Let me sum it all up, if the plane came with 3.7v, I should stick to that. And I can change from 150 mah to let's say 5000 mah without having any problem. If the 150 has 12c, the 5000mah can be 200c or even more as long as its not lower than 12c. This is last question, if I switch from 150 mah 12 c to 160 mah with 30c, will my motor be more powerful and decrease the fly time? Or won't be more powerful but last longer? And if I have a 20c 200mah vs a 20 c 5000 mah, they will produce the same pow
@Johnnyperson132 Right, if it came with a 3.7, then stick with a 3.7. And if your motor gets faster with a higher C rating, then your old battery didn't have a high enough C rating. The motor will only pull as much power as it requires. The battery just supplies the power, the motor actually pulls the power. Rc-Help.com
Another question, what do u mean when u say my voltage is right, how do I know that? Another stupid question that I think I know but I am not sure is that u can't switch from a 3.7v to a 11.1v right because it will burn? And as long as the voltage is the same, u can use however big mah you want? Like switch battery from a 150mah to a 1500mah? TY for answering the question. I appreciate.
@Johnnyperson132 The only real way to know the voltage is with the specs of the motor it's self. If it came with a 3s, then stick with a 3s. And you are correct, you can run as much mah as you want, as long as it can carry the physical weight. Also, you are correct that if it's spec'd at 3.7v, you can't run a 11.1 on the motor without smoking it. Well, you can, but it won't last long lol. Rc-Help.com
Hey I am new to plane and helicopters. How do u know when u have put a battery that is too big for the motor? Another thing, if I normally use 12 c battery, is it ok if I switch to 30c with out having any problems? And the charging rate is battery amp/1000? So if I have a 150 mah battery, I should charge it at .15 right?
@Johnnyperson132 As long as your voltage is correct (2s, 3s and so on), you can run as big of a mah and c rated battery as your aircraft can handle. It's only bad when the C rating is too small. So going from a 12c to a 30c is perfectly fine. And your battery will tell you the C charging rate. On a 150mah battery, you are correct with .15 amp. On a 1000mah battery, it would be 1 amp and so on. More info on our forum, hope to see you there. Rc-Help.com
@ABLSHATTA It's been a while since I purchased this charger, but I think it came with Deans plugs installed on one of the leads. If I'm thinking of another charger, then yes, I soldered them on. But I remember one coming with them. I did just look on the page where I purchased them, and it does NOT come with the Deans plug installed. So either they changed what plugs it comes with, or I'm thinking of another charger.
@RcHelpDotCom I'm new to this and i'm confused.The first equation was c rating x 1000/1000= amps. Then later it was c rating x mah/1000= amps. So i have a 3800 mah, 25c, 3s battery. What is the amperage?
@pstock426 On the first battery, it was a 1000mah battery. Thats the reason I had c*1000/1000. If you have a 1000mah battery however, the amp rating will always be theC rating. On your battery, it would be 25*3800/1000=95 amps. Another way to do it is to start out by dividing your mah by 1000. mah/1000*C=A
Hi. I have some questions i need to get an answer on from someone that understands :)
Can i have as many mah i want in any model if the battery is light and small enough for my model or could i damage the electronic? Same with the c-ratings, could i use as high as i can get my hands on or can it be to much?? Or is it the votlage only that destroy the electric if it get too high?? If the are limitations , how can i calculate what battery mah and c-rating i should use? best regards/ richard
@vattenskoterchaffor You are correct, you can have as high of a mah or C rating as you want as long as it fits in the model. I would suggest a higher than required C rating just in case you want to go with something bigger motor wise. Just match the voltage, and the rest can't be too big, electronic wise.
If there is anything else that I can help with, come hit me up on our forum. I'm on there all the time. See ya soon. Rc-Help.com
@vattenskoterchaffor One thing to remember is the motor PULLS the energy. The battery and ESC doesn't push it. If you are burning wires, then the wires are too small for the amp draw. If you trash an ESC, then the ESC needs to be bigger. Just like you can't run too many mah or C rating, you can't run too big of an ESC other than physical size and weight. Hope this helps. Rc-Help.com
@RcHelpDotCom I am really satisfied with youre answer :) This is the main thing that was holding me up on my model building :). Burned one old reciver once when i connected a pretty strong battery (voltage was same but with many amp) and have never dared too try again :) but it was probably the reciver that was in really bad shape then, i thought it was the power from battery hehe. I will for sure come in too youre forum.See you there some day
@vattenskoterchaffor Remember to never put more than 6vDC to the Rx. This is where the BEC or UBEC comes into play. In the smaller ESC's (40 and below) they are almost always built into the ESC. But when you get up into the big ESC's, you have to run an external BEC. I'm guessing it was the voltage that trashed the Rx and not the amps. As with the motor, the Rx only pulls power, the battery doesn't push it. Don't be afraid of it, get out there and fly! :-) Rc-Help.com
@Nitroazza You are correct, 1000mah does equal 1 amp. But, when I explain this in the video, I'm doing so for those that don't understand this concept just yet. Most people are running 2200's or 2650's, and it can get confusing for them. So I chose to explain it with the extra step involved. Thanks for the comment, Hope to see you on the forum soon. Sounds like you would be a great asset there. Rc-Help.com
so if i get a tekin rx8 bl which has a continuous draw of 210 amps, a 5000mah 45c-90c peak 3s lipo will be ok? because you said c rating times mah = amps so 45c x 5000 = 225,000= 225amps right so that will be fine because the motor continuously draws 210amps right? please reply
@landonowski I'm going to guess that you are talking about the 2200mah battery. At a 1c charge rate, it takes about 45 minutes from all the way down. If you have a battery that you can charge at a higher C rating, then it can take less than 30 minutes. Hope this helps. If you have other questions, come on over to our forum. Rc-Help.com
Thanks for that nice video. I fly nitro helis as of now but thinking of getting electric helis next time. Thinking of the new T Rex 550 electric or T Rex 600. What batteries should I use with these machines? Thanks and happy flying!!
@iamsonny7 Sorry for the late reply. I used Turnigy 6s 3000mah batteries (one in the 500, and two in the 600) when I had mine. Even though they are larger than what they suggest, the heli was perfectly balanced. If you want to get more indepth on this, come on over to the forum and post up. Hope to see you there. Rc-Help.com
I was watching another vid about lipos and he was very thorough in his teaching so I don't know Who is right you or him he said 3 s means 3 are wired in series p would I guess be parallel ahhhh help I Jackie even moved to lipo yet cuz I wanna know it all first
@yfs2times Each cell of a lipo os 3.7 volts. A 3s lipo would be 3, 3.7v batteries wired in series to equal 11.1 volts total. I will be doing a new video shortly on matching everything up, so subscribe if you haven't yet so you don't miss it. It will better explain everything that you need to know about lipo's, brushless motors, and brushless ESC's. If you have any more questions, post them up on our forum at rc-help.com. Hope to see you there.
Hi tony I hope its ok to ask since you are in the rc hobby very long what sort of Lipo battery brand would you recommend that is not so expensive and at the same time that would last long.
@reynolds26n You can ask anything you want, that is why I'm here. The Blue Lipo brand you see in the video from Hobbypartz has worked for me really well. Also, in my 250, I'm running a Gens Ace battery, and I love it. In my 450, I'm running a Zippy and it's working pretty well, and in my 500 and 600, I'm running the Turnigy batteries. They are all doing really well for as cheap as they are. Now, the Gens Ace are going to be more, but you get what you pay for too lol.
@reynolds26n Also, if you get them, do it from hobbyking in the USA warehouse. They are by far the cheapest. If you want, you can come over to my forum and I will get you links to anything that you are looking for and help you with your decision. rc-help. com/forum is the addy, just be sure to take out the space.
