Thanks , you just saved me from buying an expensive power supply for my lipo charger. I can get unlimited broken computers at the transfer station(dump)
Conclusion ? you can put a automatic switch in place of manual switch. and where you wanna go with this video ? i dont understand nothing you done ther, cut a bunch of wires, 12VDC ? you could just left the Power suply intact and do your 12VDC. and what i mean with good charge ? faster ? or better ?
@obsequeiousphil try to load more than 17V, the Amps doesent matter, the law say more Amps better and faster charging and if the Volatage low or upper than the source you could burn the source or the PSU dies.
Does the single yellow wire carry the 10 amp 12 volt load OK (without heating up?) Could two yellow wires (from different harnesses) be attached together if necessary?
I'm in the process of converting an old ATX PSU to power my Turnigy Accucel 6 charger. I'm just looking around for ideas of the best way to connect the charger to it. Maybe bananas, I'm not sure yet. Anyway I just thought I'd point out that you said the black wire is -12V, which is isn't. I forget which colour that is but the black is 0v or ground.
nice video.I have bought a f-20 that works with a li po 11.1v battery . the problem is that im trying to charge it with the specified charger but it wont charge only a red light [power] is on .the green light doesnt come on .its a winsky 501bc charger .is there any other way i can charge this battery . where im from ,i cannot get another battery r charger n to oder it will be very expensive
That's all great, but it's pretty useless for people like me who have no understanding of amps, voltage, wiring, circuits... whatever. It may as well be in another language.
@RCSlashJFREE2003 Normally it shouldnt be any problem, most chargers including the cheap $10 turnigy ones control the input of the voltage somewhere between 10V and 17V DC even the 4-6s chargers only require a 10V-17V DC input.
So this means the charger raises the voltage to what they require its a extremely simple process the only downside is that it will draw a little bit more current doing this but your batterys receive the same and your PSU can easily handle upto 8amps for charging like this
I think you mentioned that power supply was a 250W? If so, do you know how large a pack you can charge with one 250W power supply? At least a 6S or two 3S simultaneously? I have several 3s/5700mah packs on a scooter and so have 4 small 3s charger/balancers and one 6S charger/balancer. I have a buddy shipping me two 300W power supplies and am wondering if that will care for all.
PSU power is the TOTAL power it is capable when ALL rails are driven at their rated current (which many times cannot be done w/o smoking it).
The reality is that you wont get 300W of +12V out of a 300W PSU, it will depend on what brand it is, how truthful the specs are, and how the mfr. designed each supply rail.
You have to check the PSU label for the specs.
Also, you CANNOT connect multiple PSU outputs directly together.
No, you cannot use a PC power supply to successfully charge your car battery. 12 volt car batteries (they are lead acid batteries) need a constant 13.8 volts to charge them, you also need some method of knowing when the battery is fully charged so that you don't overcharge it and boil it dry.
@1Davo2 well in a pinch, you can. As long as the PSU has a load on it, it can output anywhere between 12.30v to 12.70v @ 12 to 14amps. It's good enough for a float charge but just be careful the battery doesn't get too warm.
dang, u must be smart im 12 and i made rc under carrage lits of at back viberator and halloween lights and my video will be up soon 4 that but this seems difficult and you can charge lipos of the wall bro i do it 4 my eartquake 8e lipos 2s so idk comment back dude nice job;)
Or worse, don't do THIS: My PSU fan bearings were dry; it would go slower, make noise and stop. Knowing exactly which holes the blades were behind, I would by feel, poke an unbent paperclip into the "blade area" and flick the fan and get it running again. I did this many times. Once, leaning over at an awkard angle, going by feel, I poked the clip at an angle and not straight! The loud "BANG", sparks, instant shutdown, tiny wisp of blue smoke, then "the smell" says it all!
Good video, but one small mistake - when you were showing the wires as yellow (+12V) and black, it's incorrect to call the black -12V on an atx supply. It is actually 0V, or ground, or the circuit common, because there is 12V difference between the yellow +12V line and the black line. The -12V line on an ATX supply is the blue wire, so there will be 24V between 12V and -12V. However, if you wish, you could simply just refer to the black wire as "the negative wire" if you feel that is more clear
Absolutely. I was going to correct him too. Ground is never called "negative x volts" as some rails ARE negative polarity. Ground/Black is always the reference point.
@yaaddamean No. The charger will only draw as much current as it needs. 42A refers to the max possible current, not what is being drawn at any given time.
hi, i have a question to you; i've got a battery. it's has 5 wires. black+red is the first group and black+red+white is a second group wires comes out of battery. it's says on it: 850mAh and 7.4V. i want to charge it with a power supply. is it possible or not? i'm scared it's may explov :P btw, i guess it's a lipo battery, i'm not sure.
Hi Nightflyer, I was wondering if you could help me. I'm new to the rc flight world and you seem very experienced. I just got an Eflite Blade mSR and it is great but I am wondering about the lipo batteries.

I have been doing it just because I thought it was good to do so, but I have been hearing this may actually cause lipos damage.
@frankovich213 you can recharge lipos from any level of change because they dont have the memory effect but overdischarging them may damage them but most have a micro controller that shuts them off before they are discharged too much.
@xmodsdude Thanks for your help, also do you know much about 12V Gell Cell batteries? I was wondering at what voltage are they fully charged and the voltage for when they need to be charged?
@frankovich213 srry i have no experience with gell batteries but google around and you may find something. Also there is a typo in my previous post it should say "you can recharge lipos from any level of charge*"
can i use my psu to charge a car bettery? it gives out like 40amps and its an OCZ game xtreme 600watt psu but the battery is a big 600amp with 72ah. will it work if i just connect the +12v wires from the psu (yellow) to the +12v terminal on my car battery and the same with the GND wires to the GND on the battery (black) ? thanks for any help
I am going ti get a turnigy accucel 6 with my b'day money soon. I have a power supply that i might be able to use. It says. 12v 1.5a switching. Does the switching mean anything and is it ok to use?
your the best dave...helped me so much....i got a newer pc power supply i got a switch but the van wont run when i swich it on....but when i connect the green and black cable the van is running....thank you....greetings from munich...
Why did you leave all the unused wires there? I desoldered all but 3 blacks, 3 reds and 3 yellows and removed them. Then I soldered the remaining wires to red, yellow and black binding posts on the case. Then I fitted a cigarette lighter socket into the hole where the wires used to come out and connected that to the yellow and black. It makes for a much neater job.
got an olde PC 12vdc 5A supply jumped from the green to a black and a yellow and black running to my eflight 1.8A lipo charger but my supply only was reading 11.74 output - guess ill need to get a better supply --took 3 minutes for the brushless fan in the supply to quit vibrating but it did - i think its a lot faster @ 5 A. than the little Dynam 1.5 A supply was - even tho im only getting 11.74 VDC out of it -
Don't throw out that supply! The 12V won't reach normal voltage without some load on the 5V supply. Just put a 4.7 ohm 10W resistor across the 5V (red and black) and you'll get 12V off the yellow-black.
@Geoffh777 yep- its pulling my lipos up to whatever theyll take - some stop at 12.4 and some ,(my good ones), go up to 12.6 - thanks Dave and Geoff-- what do you use the red one for Geoff? i cut off all the xtra wires coming out of the box
i got a ATX PSU & it doesn't start .... i got a switch & doesn't move they are both brand new what am i doing wrong do i need to short the green + black?

Oh yeah, every PSU these days have switch in the back, only the really old PSU doesn't or some of those brandname PSU used in system like Dell don't have switches.
Unlike some of other PC ATX PSU convertions you have seen, resistor is not needed, you simply connect the charger to your 12v molex of your PSU.
Another important note is... depending on the load 12v can go below 12v. Keep that in mind.
In my personal PC, I overclock my system and 12v dip down to 11.8'ish.
There are two type of 12v rail in PSU these days. Most PSU these days use multiple 12v rails with each providing around 15A or so depending on manufacturers (labelled like 12v1, 12v2, etc...). Also there are PSU with single 12v rail. I personally have in my computer is 750W PSU with single 12v rail with 60A.
Which every type you get, as long as 12v rail(s) can provide enough Amps to allow you to power multiple chargers at once.
if your worried about electrocution, get some rubber gloves. also to the guy that wanted a manual charger, i make a realy nice one with a light bulb, and a diode. the bulbs wattage controls how many amps you charge with,,,,100w = .4 amps. and so on. chears
people that are planning on trying this, if you don't have electronics experience DON'T. There is enough power stored in a computer Power supply to kill you even if it's unplugged
Not at all, like I said. If you don't open the case you're completely safe. Any one of those wires will only put out 12V with a maximum potential of 24V which is much much less than the 50v required to send just 1ma through you.
you must have missed the second half of the vid where he OPENED THE CASE. also i don't care if it hits you with 12v or 50v, Amps kill not volts. a typical computer power supply has between 20-30 amps running through it, some of that is stored in capacitors and even unplugged has enough energy to stop the heart. All i'm saying is don't be careless and do your homework first.
@fireraisr it is the amount of amps that flow through you that kill you. However, you need at least 50 volts to push enough amps just 1ma though your body. At 12v you would never get 20 amps through anyone's body. Unless they were made out of copper lol.
Any 12 volt supply will power on a charger but if you need to charge 5000 mAh lipo batteries you need much higher AMPS at the power supply to charge the battery properly and efficiently.
...However, they still can and will be charged to 100%, but it takes a little longer. And that might be more healthy for the LiPo battery in any situation.
thi si happening because the switch cuts power to the AC lines coming into the ps, so you still nedd to jump the green wire for any power supply to come on, and its okay if you have more than one ground, use any of them ,they all serve thae same purpose. this video is qwsome but doesnt explain that most power supplys that do have switches still need to have the green and black wires jumped, unlike his switched power supply were he didnt need to do that. hope that helps!
TY for the vid. Great info. Quick question I am pulling 11.74v atm with my 200watt PS. When I put a load on the 5v side I can pull 11.84. I am not running any resistors. Any ideas on what I am doing wrong? Thanks for the help
That is because the PSU (computer power supply) is meant to power a computer, and in normal operation this means a combined power draw on both 5V (red) and 12V (yellow) lines.
If drawing only the 12V's is unsafe or might damage the PSU or not, I DON'T KNOW!
take a 9V and use aligator clips to hook it up to the lipo charger and when its done the battery will bee 9V charged then you have 2V left you have to charge...
I just bought (out of recommendation) the Hyperion EOS0615i DUO3, which is state-of-the-art. It takes everything up to 6S (12S), and is an advanced 2x180Watts digital charger. All types of batteries (2x6S) and power supplies (<28V) are supported. Look it up :)
I use it for ballanced/synced charging of my two 2S 5500mAh LiPos.
Hi Dave, just a question regarding the computer power supply. Is it possible to run multiple chargers off the same supply? Would you use the same source wire or another accessory wire from the supply? I have 2 extra eflite chargers(Blade400) and 1 parkzone charger, all with no AC adapters.
Thanks, you are an inspiration to all up and coming pilots! Keep up the great work!
Yes, you can use the same wire. There are multiple 5 volt supply wires however on most PS's. That should work fine, long as the PS has enough supply amperage.
Very nice videos. all of them :) i might have some questions once i get a heil, just got an easystar a few weeks ago, ill stick to it for now :)
About you powersupply, If you place a 10Ohm 10Watt resistor between Black(Ground) and +5V(Red) the power supply will be more stable when under load :)
((and a little correction, -12v is the Blue wire. if you want you can use +12v(Yellow) and -12v(Blue) to get 24volts ))
Colours can vary between different makes and models too, so always double-check the colours or the different wires before connecting it to anything!
Also, like Dream said, you can get different voltages by trying different voltages. Example, +12V and -5V would give you 17V, or +5V and -5V would give you 10V etc.
They are used by the motherboard (as in a PC) for anvanced voltage manipulation stuff, and DO NOT carry any Amperes of any use for charging batteries! They are rated in mAmps.
I flew gas for 51 years. There is more support equipment required and it is more costly and messy and loud. I like it a lot, but dont think it is less complicated. You have to know how to get the right sound out of gas or it will quit in the air. Electrics have no engine tuning requirements.
Generally a square plug with 2 yellow+ and 2 black- can be used as a 12v source. I use 2 yellows and 2 blacks. Most computer power supplies(PS) will provide 10amps at 12v which is enough for most lipo chargers. If your power switch does not turn on the PS (fan should start) then you may have to ground the green wire. As long as there is a power switch (120v) you can ground out the green wire to the chassis properly, otherwise switch the green wire. Remove the excess wires that lead from the PS
Battery's are like gas tanks. They hold milliamps that you need to fill it up. If you have a 2000 mah battery and a 500 ma charger it would take 2 hours to charge it at 500 mah an hour. All battery's are the same, but lipos need special chargers. This is a power supply to run those chargers, not actually charge the battery.
i have an allied a300atx power supply with a switch on the back.
when i turn it on, the fan does nothing and using my voltmeter, i tested many different combinations of wires to see if there was any voltage. whenever i touch the green or purple wire and another wire, i get 5v. i have tired every combination possible.
i used some simple wire and created a contact between the green and black wire on the main plug and flipped the power switch. to my surprise, i heard the fa kick on and i now get 12V from any plug with a yellow and black plug.

Hi Dave, first of all thanks for great vids and answering many questions for us.
I have few question, How many times can I charge Blade 400 battery from car battery before not enough juice left to crank the car?
Also How do I know what Amperage am I getting from 12V output from PSU? I have seen the label on it and it shows both "-12v 0.8A Max", and "+12v 18A Max".
Your welcome. Think of your battery as a gas tank and the car battery as the gas station.
If the gas station holds 100 amps of power, and your battery tank holds 1 amp, you can charge it 100 times, but I dunno how low it would go before your car would not start. I dont think you could kill it in a day, as maybe you could charge it only 8-10 times considering an hour to charge.
Yes the negative voltage, (no concern to you) is 800 mah, and the +12 is 18 amps. (1800 mah), plenty to run a charger.
Yes, that should work just fine. Red is positive 12 volts, but it never hurts to check with a voltmeter, to make sure your getting the full 12 vdc from your power supply.
what ac adaptor? The computer supply in this video puts out 12 v DC. It is used to run the charger. Usually the center pin is +, so use a ohm meter or a light bulb and battery to see which wire is what. THe stripe on the wire is usually + also. After hooking it up, make sure to test the tip, to make sure polarity is right. YOu have a 50/50 chance. Good luck.
Hi, great vid. Can I use the 12v 3amp power supply for a stock blade 400 charger to power a polycharger 4? Also, how do I know which is pos. on 12v power supply? Thanks in advance

Why did you leave all the unused wires there? I desoldered all but 3 blacks, 3 reds and 3 yellows and removed them. Then I soldered the remaining wires to red, yellow and black binding posts on the case. Then I fitted a cigarette lighter socket into the hole where the wires used to come out and connected that to the yellow and black. It makes for a much neater job.

got an olde PC 12vdc 5A supply jumped from the green to a black and a yellow and black running to my eflight 1.8A lipo charger but my supply only was reading 11.74 output - guess ill need to get a better supply --took 3 minutes for the brushless fan in the supply to quit vibrating but it did - i think its a lot faster @ 5 A. than the little Dynam 1.5 A supply was - even tho im only getting 11.74 VDC out of it -
santatigerclaus 1 year ago
Don't throw out that supply! The 12V won't reach normal voltage without some load on the 5V supply. Just put a 4.7 ohm 10W resistor across the 5V (red and black) and you'll get 12V off the yellow-black.

Will the triton charger work with a np-25 ni-mh
battery as to charge it.its a 12V 4.0Ah
cooljazzman1 2 years ago
Oh yeah, every PSU these days have switch in the back, only the really old PSU doesn't or some of those brandname PSU used in system like Dell don't have switches.
Unlike some of other PC ATX PSU convertions you have seen, resistor is not needed, you simply connect the charger to your 12v molex of your PSU.
Another important note is... depending on the load 12v can go below 12v. Keep that in mind.
In my personal PC, I overclock my system and 12v dip down to 11.8'ish.
So be sure monitor it.
xxgg 2 years ago
Some Tips for buying a ATX PSU!
There are two type of 12v rail in PSU these days. Most PSU these days use multiple 12v rails with each providing around 15A or so depending on manufacturers (labelled like 12v1, 12v2, etc...). Also there are PSU with single 12v rail. I personally have in my computer is 750W PSU with single 12v rail with 60A.
Which every type you get, as long as 12v rail(s) can provide enough Amps to allow you to power multiple chargers at once.
Enjoy.

@fireraisr
Not at all, like I said. If you don't open the case you're completely safe. Any one of those wires will only put out 12V with a maximum potential of 24V which is much much less than the 50v required to send just 1ma through you.
didaloca 2 years ago
you must have missed the second half of the vid where he OPENED THE CASE. also i don't care if it hits you with 12v or 50v, Amps kill not volts. a typical computer power supply has between 20-30 amps running through it, some of that is stored in capacitors and even unplugged has enough energy to stop the heart. All i'm saying is don't be careless and do your homework first.
fireraisr 2 years ago
@fireraisr it is the amount of amps that flow through you that kill you. However, you need at least 50 volts to push enough amps just 1ma though your body. At 12v you would never get 20 amps through anyone's body. Unless they were made out of copper lol.

Any 12 volt supply will power on a charger but if you need to charge 5000 mAh lipo batteries you need much higher AMPS at the power supply to charge the battery properly and efficiently.

...However, they still can and will be charged to 100%, but it takes a little longer. And that might be more healthy for the LiPo battery in any situation.

macdaddy1600 2 years ago
thi si happening because the switch cuts power to the AC lines coming into the ps, so you still nedd to jump the green wire for any power supply to come on, and its okay if you have more than one ground, use any of them ,they all serve thae same purpose. this video is qwsome but doesnt explain that most power supplys that do have switches still need to have the green and black wires jumped, unlike his switched power supply were he didnt need to do that. hope that helps!

That is because the PSU (computer power supply) is meant to power a computer, and in normal operation this means a combined power draw on both 5V (red) and 12V (yellow) lines.
If drawing only the 12V's is unsafe or might damage the PSU or not, I DON'T KNOW!

Hi Dave, just a question regarding the computer power supply. Is it possible to run multiple chargers off the same supply? Would you use the same source wire or another accessory wire from the supply? I have 2 extra eflite chargers(Blade400) and 1 parkzone charger, all with no AC adapters.
Thanks, you are an inspiration to all up and coming pilots! Keep up the great work!

Yes, you can use the same wire. There are multiple 5 volt supply wires however on most PS's. That should work fine, long as the PS has enough supply amperage.

Hello NightFlier.
Very nice videos. all of them :) i might have some questions once i get a heil, just got an easystar a few weeks ago, ill stick to it for now :)
About you powersupply, If you place a 10Ohm 10Watt resistor between Black(Ground) and +5V(Red) the power supply will be more stable when under load :)
((and a little correction, -12v is the Blue wire. if you want you can use +12v(Yellow) and -12v(Blue) to get 24volts ))
Dreamlgider 2 years ago
Well said. Thanks for the extra tips.
NightFlyyer 2 years ago
Colours can vary between different makes and models too, so always double-check the colours or the different wires before connecting it to anything!
Also, like Dream said, you can get different voltages by trying different voltages. Example, +12V and -5V would give you 17V, or +5V and -5V would give you 10V etc.
ThePhailedRoflcopter 2 years ago
No no, please DON'T use -12 or -5V to get 24/17V!

Well if you have to solder a new plug on, otherwise take it to a hobby store and ask them to do it.
NightFlyyer 2 years ago
Generally a square plug with 2 yellow+ and 2 black- can be used as a 12v source. I use 2 yellows and 2 blacks. Most computer power supplies(PS) will provide 10amps at 12v which is enough for most lipo chargers. If your power switch does not turn on the PS (fan should start) then you may have to ground the green wire. As long as there is a power switch (120v) you can ground out the green wire to the chassis properly, otherwise switch the green wire. Remove the excess wires that lead from the PS

To charge the blade 400 how many amps do you need.
Helipro3218 2 years ago
Battery's are like gas tanks. They hold milliamps that you need to fill it up. If you have a 2000 mah battery and a 500 ma charger it would take 2 hours to charge it at 500 mah an hour. All battery's are the same, but lipos need special chargers. This is a power supply to run those chargers, not actually charge the battery.

love the video but i need a little help.
i have an allied a300atx power supply with a switch on the back.
when i turn it on, the fan does nothing and using my voltmeter, i tested many different combinations of wires to see if there was any voltage. whenever i touch the green or purple wire and another wire, i get 5v. i have tired every combination possible.
is there a way to get 12v?

You should be able to touch the green and black wire together to trigger the switch.

SexyToshi 3 years ago
Your welcome. Think of your battery as a gas tank and the car battery as the gas station.
If the gas station holds 100 amps of power, and your battery tank holds 1 amp, you can charge it 100 times, but I dunno how low it would go before your car would not start. I dont think you could kill it in a day, as maybe you could charge it only 8-10 times considering an hour to charge.
Yes the negative voltage, (no concern to you) is 800 mah, and the +12 is 18 amps. (1800 mah), plenty to run a charger.
NightFlyyer 3 years ago
Yes, that should work just fine. Red is positive 12 volts, but it never hurts to check with a voltmeter, to make sure your getting the full 12 vdc from your power supply.

Usually the center pin is +, so use a ohm meter or a light bulb and battery to see which wire is what. THe stripe on the wire is usually + also. After hooking it up, make sure to test the tip, to make sure polarity is right. YOu have a 50/50 chance. Good luck.
