 Hello everyone, so I thought I'd do a little sort of product over review of this smart battery charger and smart charger and now I've had this for a good two years and I think it works pretty good I think it's a pretty solid charger for the money it seems to have worked really well for me because I can take this outdoors by connecting it to a battery as an input and I can also use it at home by repurposing an old power supply this is an old power supply for let me just readjust the camera a bit an old power supply from xbox and this is the big xbox work it's 150 watts see that there and that is just okay for this this particular battery charger it's okay for me to do the jobs I need to with this battery charger indoors so let's give it a quick little power up before I do that I'm just going to go over very quickly the warnings and safety tips because this is a must when it comes to charging lipo batteries well whichever batteries you're charging well you don't really want to leave them unattended so make sure that if you're going to be charging be in the room or at least have it conscious in your mind if it's you know on a desk behind you whatever that you're charging batteries and things can go wrong this does if it finds anything well put it this way on my balance charger I think there's a cable that's not quite correct and it just throw an error while I'm charging stop the charging process which is great and then makes me confirm it by hitting the hitting this wheel here need to keep this away from dust then get it get to clogged up high humidity rain high temperature and a world direct sunlight and exposure to lots of high vibrations so if you sometimes you know I'll I'll be a bit naughty because I may be driving for one location to another and charging batteries while I drive but I do have a part in the back of my round where it's just metal and that's why that I'm normally sick so we can you know reduce the chance of something going wrong power input of the charger is direct current and it's between 7 and 32 volts and make sure the polarities are correct when you're plugging in it's an xd 60 connector there and place the the charger on a heat resisting non flammable insulating surface so because the last thing you want this thing to do is be getting too warm and it possibly catch now I have never come it's never come close to that with me and I charge you know sort of three four packs at a time sometimes like these you know these are 2.2 amps and I charge three four packs at a time now I do do very I do like half c charge rates on pretty much everything so if you don't know the c rating of your 18650s it's good just to go for half c rating so like these are these are 3000 milliamp three amps and so one and a half amps is fine I'd normally charge them about 1.2 just because you know that's how I do it I'm never in a massive rush when it comes to the batteries and for these these are 2.2 amps and I've normally charged these around about 1.1 anyway so make sure that the there's a fan in the back make sure that's always kept able to prevent the air out don't have that blocked as well because otherwise everything's going to get really warm in there and not only do you cause a possible problem through overheating but it will also degrade the components life a lot quicker if they are being overheated so that's always good understand the charging and discharging characteristics of the batteries as well like I said you know a few minds if you don't know what the c rating is you know go for half c so on five amps and the same for the lipo's I mean you can you know because these are what they they're 25c so if I was to times this up I should be able to charge this at a lot higher rates than what I do but for safety I don't and you know some people say we you can charge it and double quick time and everything yeah but I just don't I just don't and to be honest with you I don't really find it that necessary to do it like that but it's your choice everyone gets to make the choices on these things but keep them within the safety spec and I normally get for half some charge races just because that's the way I like to do it and I've had my batteries for years I've had my batteries for years they don't look at this like I can't um I don't know how old these batteries are now but they're at least two years old at least two years old three years old possibly um and they're still getting strong so and there's another thing as well well I'll show you that once we get the charger on so let me just plug in this power supply first one I'm just going to plug this in here now the way I've set this up here is look it's pretty crude but doesn't do it this is that the switch what would normally switch on your uh on the power supply it detects um and so these wires are just twisted together and I'm going to plug it into there plug this in here and here we go so we've not got a battery connector at the moment so I'm going to connect one in front of you guys and here you'll see all right and you'll see that well maybe we're just a light but I feel just a light to the best I can to not get any particular glare on you should be able to see there's a little notch down here um that just means that you're going to place this notch in and it just ensures that the ground goes to where the ground should be and the uh and he just put that in there and he's uh trying to look through the camera and do this at the same time so I'm trying to keep the glare off the screen so here we go plugging the batteries it's a four cell battery so you can see all four cells and you can see the voltage on the cell and you can see what voltage the total is for the battery you can also see which should be able to on the next one I think it is oh for some reason I can't see the input voltage but we'll maybe come around to that in a second but if I just quickly just hold down on this just go back there for a second and hold into here so this is if you press this um kind of what they call this but just press this uh rotation uh button in because it's it rotates like that let me just set that back to 130 watts because that's my maximum power input this is 150 watt um power supply so without trying to make it run full board um if I just do the max input as 130 the minimum input input voltage is 11 volts there um this is a 12 volt supply so that's where okay backlight is automatic uh now this makes the screen go light or darker I don't know if you can see on the camera so well but there is a little tiny I don't know if you should just be able to see that there's a sensor so I've got my finger over there I'm just trying to see if it will actually act like that and compensate there you go with the lamp there it compensates if I take that away yeah so which is pretty good because if you're out in the field which is what I use this for generally um then um it's it's a really sunny day and the sun's you know sort of on the screen it can make it hard to see so for that lighting up that's pretty good I really do like that about it we got our volume for all of the the noises that it's going to be making where you heard it there where I just put it in the wrong way around it was really good because it just tells you it's high voltage throws an error and it won't do anything it's you know it sort of protects itself it is what a smart charger completion tone you can set this so you can repeat it if I just move down these for you single or repeat I get to repeat it in case I'm just not listening correctly or I've stepped out of the room the firmware I'm not going to go into any use sort of stuff at the moment we've got different languages one set to English system self-checking that's pretty good so you can just hit that and let it do it let it do a self-check again if there's an error just press up so we we're happy that we've pulled that error out that's what we're going to the system self-checking again well let's just go there so it's just happy with itself that everything's working as it should be this back go thing I've not really looked into that particularly there's something I could look into but that's it for its system settings so we're going to go back now again we've got no voltage there so I'm going to really put the voltage in this time this time I did it again I'm so used to doing this on the balance board I'm not plugging directly into it because the balance board's always left in but that's fine we go to show it again that we have a good system it's just going to give you a warning that you've done something wrong nothing goes bang nothing goes pop and we're good with that now let me show you I've got mine set up so as you can see a lot I've got it on one amp there if I was going to start doing this so you've got your tasks which will be charge discharge and storage now it says that you can go to three amps discharging that does not happen it never does I mean it's eight watts maximum discharging so it depends on how many cells you have you can maybe work that out for yourself depending on which battery you know for how long it's going to take to discharge I've got a separate little piece of kit the cheap piece of kit also doubles up as a server something that I can set up my servos with and that's much better for discharging so but you can charge and you're discharging and you can set your storage now if I do have a little bit of a yeah with this is this is not as solid as it used to be sometimes it will miss sometimes it will jump a couple but if you're just gentle with it it's still it's still good it's not a it's not a negative it just doesn't seem to feel as great as it did the first time out so we're on the task of charge our battery type is a lipo it does go for several different battery charges lihv lipo lithium lithium ion life pd which is your like car batteries and the nickel cadiums so I've set my answer lipo and now we've got a cell voltage how high do I want this charge now it's got a thumbs up there for 4.2 which is which is ideal without that's going to charge it fully and but I just charge my just slightly under it really doesn't make a great difference but if you I look at it like this if I'm going to put a full stress on this every single time it's almost like trying to run it full board so I just drop it a little bit under for the you know for the little bit of restricted power there I may get a little bit of extra life out of the battery and I can't afford to keep changing batteries and and stuff like that let's say I do understand they are consumables and you are going to get through batteries but I don't you know I don't fly my packs like that I just fly around just general Miranda in a lot of the time or or try and go for a bit more of a long distance thing if I do that I will go to the 4.2 if I know that I'm going to try for let's see how long we can keep it up in the air for a lot with my clock I've managed to get 20 minutes out one of these battery packs and I think that's pretty good I think that's pretty good so I'm just going to leave that there just for now it will do an automatically cell count you can adjust it if you want to but because it counts itself anyway and it will go from 1s all the way to 6s which is brilliant taking into account it will do the 1s and then the current of course you know you can take this all the way up to 14 amps if you so decide you see the little jumps there when I was just doing that right like that it's a good look you get to see that there's just a little tiny bit on there but it's fine it could just be a little bit of dust or something maybe I could take it apart but I'm just going to we use that down and get that down to the 1 up but generally as you can see that's pretty down good you see the big jump then when I just moved it like a couple of clicks and it's gone straight from there to there that can be a little bit annoying but I'm not going to you know 1.1 is fine for this as well to be honest with you I've got charges a lot higher rate but I just don't I just don't uh if I'm you know if I end up putting four packs on yeah if I end up putting another three packs on I've got four packs running on it then yeah you know I'll put four amps on there or something like that but I just I just don't tend to do that and then we just get down to start um not going to do a charge on the battery doesn't really seem to be much point um um that we can go back but I do like this whole screen thing here because if you pop down there as well you get to see now the input input battery input voltage which is 12.2 volts that's what this is reading as you know you you don't expect it to be absolute spot on I mean that could be correct it may not be correct it there it's going to be around that voltage which is just okay we've got temperature we've got the amount of pieces I believe this is the amount of time so I've cycled this for charging 172 times and that's pretty good that's pretty good um I don't actually know what these are for let's have a little quick look and I'll bring up the um imagery on here where it tells you what that's actually for if it tells you and I'll tell you something else it should show us as well if we hit down I think we have to start it so let's just do the start and then if I confirm current start let's go back what I'm looking for is there we go we will get to see the the amount of resistance on each of the cells which is pretty good but just let it let it go through a little bit first before it will show us that so even though we're charging now we're charging at 1.1 amps we've got six million amps gone in um we will get to see very shortly once he's taken those measurements of he's missing that one of those I've got to go back upwards there we go so now we get to see the um resistance now nine million that's quite a bit 1.8.1 6.3 9 million that's quite a bit but that will change as this is becoming more charged no it will change as it becomes discharged as well but it's a pretty good charge like you know like I say I've had it now for the amount of time I've had it I can't remember exactly when I bought it but I do remember this summer it's been kicking away it's not really done anything this year because of all these lockdowns um last year it was with me out in the field the year before that it was with me and so you know there's a couple of there's a couple of years there it's well out of the warranty it can get a bit noisy when that fan starts going around but personally I don't care if it's cooling down the internal components I'm happy it's doing its job as it should be doing so I don't mind about that at all some people that might irritate them when it's in here everything's really quiet and it's on it does seem quite noisy but it's a little tiny fan trying to do a lot of air movement so you've got to expect that a bit if you could have a bigger case you know with a bigger fan in there then maybe I'll just slow it down and it won't seem so loud but I think if that's the only fault and a little bit of a miss on this from time to time it never used to be like that that's something I've noticed recently it could just be dust in there so it might need just taking a part and taking that out and giving it a bit of a clean out if that's the only problems I can find with it I'm more than more than happy like so if I'm using this indoors I'll I'll charge with this power supply at the back here but if I'm using it out in the I'll use this battery here cos it's a 25 volt battery 22.2 nominal and 10 amps which you know gives me quite a lot of power about 250 watts of power an ideal to take out and it means that I can you know get another four or five even six depending on the voltage that I come back in with with a battery pack I can get another six charge at least out of it and you can you know because I've made up little bits and pieces I can charge my phone and all sorts different charges on there as well which is is great it's absolutely great so if anyone said to me hey would you recommend this is anybody but I say yeah yeah for the price I think about £35 and that's not going to equate to much more in dollars to be honest with you don't know anything so very good very good it does everything that you'd hope a charge would do and include and thrown out the errors which is fantastic because that is the safety side of things for me is very very important when it comes to these things so we go back up there you can see look the if you roll back the video but you'll see that the the actual resistance is changing and the voltage is just going up very very slightly as it's only charging at half a C so let me just put this into how you stop this then so it's that easy to stop this thing then as you can see I've I actually switched on I just done it again so I forgot to do the stop part so that easy to stop this it's just you can adjust the current while you're going or you can just go for stop or go back again to you you just continue what you're doing and you'll see you can see that just continues but I'm going to go to the stop now hit that and there we go where it's charged you'll have two indicators of it being charged you'll have a pretty much quick charged which will give you a green screen and a beep to let you know hey you charged your packs ready to go but if you want it all to be thoroughly balanced leave it until the blue screen kicks in and it will give you an indication then just by leaving it alone when the green screen's there and it will give you an indication then by showing you a blue screen and beeping beeping giving it a pause in front time and beeping again to let you know that it's actually fully charged and balanced so there's another option with the charging there where you get to take it off if you want to just quickly get off and get your flight done and uh or just leave it for it's fully balanced so there you go guys that's my uh my impressions of this and I hope you enjoyed the video any comments please stick down in the old comments section and uh leave us a thumbs up if you like what i've done here speak to you again soon take care everyone bye bye for now
