Your LiPo battery charger's specifications are all lies. 300 watts? 14 amps? Try it. See if you get it.
If you want to know why your lipo battery charger is not reaching its full specifications, here's the answer: you're running it off of 12v. To get the most out of your charger, you probably need a 24v power supply. I'll tell you why, and where to get one!

Parallel charging on the bed. What could possibly go wrong :)
Jakub Steiner 😂 hell no
It's just an example. There was no light on the floor of the hotel room. Come on... I'm making videos on the road you have to make some concessions. Of course I didn't actually charge the batteries on the bed.
You charged them in the bath instead? :)
Hey there's a thought, safety wise, what type of bath (or sink) would be good to charge lipos in? Cue a chance for someone to explode lipos in sinks & baths (outside obviously) for science! and fun!
It was a joke. And a good one 🤣
@@JoshuaBardwell Lol you got really defensive there
That's not Ohm's law, thats Watt's law. Ohm's law is V=IR (or R=V/I) and is about resistance, measured in Ohms
Damn, you're right.
Letting us nerds down! 😂
Learned something 👍
Joshua Bardwell I guess you learned something today
@YerRandO Wait.... Are you the guy still on 3.2!?!? I thought that was a myth!
Very clear. Loved the explanation Joshua.
Hey Joshua- those of us that fly large electric helis as well are using various server power supplies in series- personally I am using hp dps1200fb power supplies- usually you can pick them up on ebay that have been pulled from servers for 30 bucks or so apiece.. although the last pair, I got 2 for about $30- it is obviously a bit more diy.. but purchasing a comparable benchtop powersupply is way too costly.- in my heli charging case I have 2 in series for 24v 1200 watts- it is enough to drive a powerlab 6 and a powerlab 8. I have had both going showing a total of ~60amps on the charger side of the power supply.. with that setup, i can charge 6 6s 5000's in about 20 minutes on one charger and a bunch of either 3s or 4s on the other chaarger at the same time.
Thanks for the info Joshua! I was just about to get enough batteries to max out my charging board so this will help immensely!
we appreciate what you do for us Josh, Thank You. Cool ending too!
Excellent!... JB. You are a Huge source of information for technical. You are a GOD for FPV community. Thanks for all your videos!
THANK YOU MAN!!!! BRAND NEW TO ALL OF THIS!!! your explanations made perfect sense! Now off to buy a charger and power supply
24v for the win! I run my isdt and ts100 off of a 24v psu. I get the whole 14a and the ts100 heats up in like 12 seconds :D 👍 👍
As always, very good, VERY informative. You made a 2 minute video into a 10 minute video but not in a bad way, but in an epic way!
I just love your sense of humour. Kudos.
Hello JB, This was a really helpful video. Thanks JV 😎
Look like you're having a awesome time..Thanks for taking some time out for us
Joshua has done it again. Many others and I just learned something. No BS, thanks Bardwell...😎
You have got so good at talking to the camera and explaining things in such an articulate way. Also great intro and outro! I unexpectedly watched the whole thing
Dear Joshua, from all the youtubers your content is the most precise and technical, it is great for people like me trying to understand electronics to get into te fpv. I’m an airline pilot and I’m making my own ground school before I fly ( like with regular aircraft), the info is very dispersed and to find something sometimes you have to be very specific on the search, or other times the info is obsolete due to new stuff.
It will be awesome if you make short videos about each part of the drone, there is a lot about radios and goggles, but when it comes to motors or blades or any other part is hard to find info when you are new. If you decide to make a virtual school showing rotors, amperage, speed, capacity..... specific things about each part, I will gladly buy it and I’m sure a lot of guys like me would buy it.
In aviation you have to finish the ground school before you go to the plane, and I’m trying to do the same stuff here but as I told, is hard to find info. I remember in flight school there was a company name Kings school, they are an old couple giving aviation lessons and I remember that there were like 40 dvd and each dvd was about an specific theme with precise info, if you have time, take a look of that and If you like it I will recommend you to do that with drones, and I’m pretty sure that a lot of people will buy it. Anyway thanks again for your content and sharing all your knowledge and as I said you are very technical when speak and make us understand .
All the best to u guys. Enjoy. That's wat life is about. Great vid. Helped me understand a lot
Excellent video. Just so happens that I am in the market for a power supply for that exact charger.. THANK YOU!
Subscribed. Thanks for the clear explanation on how everything works.
Great as always Joshua:); following your math for the ISDT T8 "Input Amp limit 35 A" so times 24 volts = 840 Watts
Great video! Alot of help.Thanks
Great info here and I almost missed this info if not for the Arrma forums before choosing another charger. I bought a used iCharger 4010 duo and an 12 volts 75 amp RL power supply due to the iCharger input limit being 65 amps! I can charge a 4s and one 6s 6000mah lipo in under 40 minutes at only 1c. Love it. All kinds of setups. Can tell it to storage charge or discharge to whatever voltage you want (I prefer 3.85v/cell). It will discharge or charge until it's done in just a few minutes. Can discharge at a high rate into light bulb bar or resister also. All with a 12 volt power supply.
RC & quads are really alot of good education & information. Thanks!
thank you very much, JB, please stay safe and healthy 🙏👍❤️🥃🥃
Thank you, this makes a lot of sense. I was trying to figure this out almost a year ago and ended up getting an iSDT T8 and a 750w 12v server PSU. Input from that PSU is ~422w (35*12=420) and output is around ~396w. If I'm understanding right when it comes to the ISDT T8 for 4s batteries 35*16.8=588w, so I guess my charging situation is not the best that I thought ... but also not the worst either. By pure luck, it just works for what I've been using it for (10x1300mah 4s at 1c or 2c... on a JB strix board ;)) If I had a 14a input limit... YIKES.
Great video! That little bit of math was making things so clear. You saved many hours of charging time with this story :-) Also explains why my 6s field charging lipo is doing such a great job.
Thanks Mr bardwell for another great informative videos
Great info JB! Like the light hearted bit at the end@👌👌😀🏆
You've convinced me. Actually I was on board with this before from your previous videos. I've got my server PSU based power supply build already in progress. 24V, 870 Watts baby yea!... :)
The input range of the iSDT Q6 Plus is great, I can run mine off my 7S ebike battery, allowing the full 14A output for parallel charging.
phenomenal explanation! Very easy to understand and follow. Thanks
i have been using my thunder power 820 charger for 9 years she came with me from 3Dhelis to my quads and still works like its new . the charge is 800 watts 20 amp 2 charging ports and my maxamps 24 volt power supply
Even your most boring videos, such as this one, are still entertaining enough for me to watch on my lunch break and informative enough to make me say "wow I learned something".
Look into icharger 65 amp input limit on there 4010 and upto 50volt input i have 2 of these setup they are total work force chargers
Great video thank u for the info.
I’ve been looking for something (not very hard) to replace my XT60 spliced laptop power supply (it runs at a measly 16v) that I used for the ISDT Q6. Looks like this is the solution. Thanks JB! 👍🏻
What a helpful video. I"m in the market for a new charger because my old one couldn't handle my 6s battery even at 1C. The charger is 6s capable but only at much lower amps. Crazy how misleading most charger specifications seem now that I know the math. Thanks for the info.
Good info. Also note, ISDT T6 Lite is 30A input and T6 and T8 are 35A input. Being pragmatic, at 14A I can parallel charge 8 1500mah batteries at 1C. I would be curious to know how many flyers actually do that.
Bro I gotta say. Really enjoyed this one. 👍🏼
Thanks for this, it’s something I feel I should have guessed as my Turnigy chargers only ever push out 3.2amps * 16.8v yet they says they are 300 watt, just presumed they were lying like car manufacturers do for mpg!
Oh i definitely learned something today! you just confirmed what happened to me with my newly converted 650 watt PC power supply and ISDT T6 lite. Using an old hard drive to provide a load so the PS can operate at full power until I can solder in a 10w 10ohm sandbar resistor. I didn't realize it was an input voltage /watts that was causing the restriction.
T6 Lite has something like 20 amps input current so it can do better than the Q6 in this video.
Hi josh, i found explaining ohms law easy if you use speed time and distance, its clear if you change one, it effects the others. also using a triangle, you can cover the one your trying to calculate.
Killing it, good on ya!
Great video! I learned something today... again. Seems like a bad habit when I visit this channel. I'm getting to a point where I'm gonna need to start dumping less desirable knowledge in exchange for Bardwell knowledge.
Great thanks man
it’s so true what you say, that ISDT made its own PWS with voltage output of 27 V. it’s not a random choice.
nice explain! thx :)
Well explain thanks for sharing.
Thanks so much for your wonderful content! I think you may have answered this on a previous comment but isn't the power supply that your suggesting to buy more amps and Watts than the q6 (let's say for example) is rated for? Why then would that not fry the q6? I'm unfortunately ignorant when it comes to electricity. Also, I just purchased the banggood one. Would you be able to recommend a good video on how to wire it? Thanks 😊
thank you for your videos
Hi there, informative video, is this the right product on bang good? Would this power supply be able to power the ISDT Q8 Lipo battery charger? I'm looking for a power supply for the ISDT q8.
Thank you for your reply. So from what I understood even if there was a problem with the power supply these kind of chargers have some kind of fuse protection... right! so that's why you you said that it was not to go (sorry I forgot to say that the battery was at 3.80 and this happened almost 35 minutes after it begun to charge) in smoke. Thanks again.
Icharger x6 puts out 24a charge rate off a 12v marine cell battery. Amazing little field charger
Hi! I really have a question! I have 2 ISDT chargers. 1 that is 500W 20a and the second 200W and 8a but when it comes to charge batterie the first charger always stays at 0 amps and 0 mah after starting and the second chargers start charging and the amps are going up but then “abnormal input voltage”
Power supply is 400W 24V 16.6a
Please help me out!
Thanks a lot and keep the amazing work!!
Besides what law it is, it was explained well. Thank you sir.
Thank you - it was very useful. I was using modifyed laptop charger to supply q600 plus to charge not more than 3-4 batteries, but now I'm having more batteries and I was looking for new power supply - this video was right in time! And Hey - I already have your JB v2 board - it's smells power muahaha!
old vid but just wanted to thank u for the very well explained info. news to me as i was debating on a 150 or 300 watt but will most likely use 12v so 150w now sounds better and will save me a lil money. thanks
Which leads me into my favorite electricity joke.... Watts up Ohms! 🤣🤣😂😅😆😐😐😑😑😑
Thanks ! Lol at the end, crazy guys 👍
Anyone know how noisy that charger from Banggood in the description is? I had a 12V unbranded Chinese one like that but it was so noisy I switched to a lower output laptop PSU.
Hi Joshua,
Just catching up with some of your older posts.
It’s funny how critical some people can get when you make an error. Anyway i just wanted to say once again great video.
Did you actually test the charger by supplying 24 Volts DC to see how that affected the charging current?
And yes I did learn something today. I would never have thought about increasing the input voltage. Great Post!!!
Lol i love this guy. Always extremely helpful. Ty
I was dealing with this.... I was hitting my 15A input current limit on 12V and getting the same 10.8A at 4S charge. Q6 Pro. Haha. I'll change it over to my 24V supply.
Hey Joshua, quick question. Is it possible to have an intermittent motor connection on a Flight Controller? I’ve tried two different Revolts and both drop on the back left motor. They arm and spin up, but then drop after 20% throttle. And I’ve tried MULTIPLE different ESC’s. And PDB’s. And BetaFlight controllers work, but the revolts dont.
I have a flex power tool with 24V battery but no charger. I would like to know if I can use some kind of setup to charge this 24V battery which I think needs something slightly higher than 24 volts to charge. Thanks.
It's always worth comparing different chargers amp ratings if you're charging 4S, From that point of view, the iSDT SC-620 was the best value at the time, and has a 24A input limit, that means the max output is 336Watts, the 12v 24a input limit is 288watts which isn't too bad really, if you have an old Computer PSU and want to spend less than $50 on a charger i'd really recommend!
Thank you. Nice informations
Perfect sense! Thx!
Is it suitable to power ISDT Q8 to charge Lipos with a Li-Ion 24V Battery 20Ah? I ask for it overall for the discharge ratings. some recomendations?
Joshua, what is your Recommendation, for a AC to DC Volt/Amps Charger for the " ISDT Q6 Pro BattGo 300W Charger". I 'm looking to charge mostly 3s 5000mah batteries 2 at a time? Any help is appreciated.
I use a 12v psu turned up to 14.5v I can get about 13a at 4S voltage. Tops out around 230w.
I would highly recommend an Altronix power supply over other brands. We use them for nearly all of our panel builds in commercial and industrial environments because they nearly last for ever. They are also made in the USA. I’ve been using an Altronix 6amp 24vdc for charging my lipos.
you are funny man, I do appreciate it,
got a quick question please
I want to get a portable charger ( probably Q6 ) and a big battery to charge my lipos when I am not around power supply, what battery you recommend please?!
I've got a D2 charger at the moment
thanks a lot
nerdsplosion. love it JB
Totally just had this same scenario happen today with the same charger!
Everything you said makes sense to me. But i cant figure out why my hobbymate d6 charger wont charge my laptop past 1 amp at 19.5v. Its plugged it into the cigarette lighter in my car wich i know can supply at least 15 amps. Now some laptops can be tricky to charge without an oem charger but ive managed to do it with the d6 charger from a higher voltage. It really seems like i need a better charger... Any thoughts or knowledge is greatly appreciated.
Good info - even for us "fixed wing flyers" who watch your channel 🙂 Since I fly 4S 5000 mah batteries and have a power supply that has two output ports 12V @ 14 Amps each (29 amps total), I don't think I'll be trying to parallel charge multiple 4S 5000 mah batteries with my current setup.
So useful
What about 12v 120w 10a 20 usd charger for it? Im gonna charge 2x3s battery at best. Thx.
That is why you should use multiple Q6 Lite over the bigger 300W Q6. Also you don't have to watch for having all packs at the same voltage. Using 3x Q6 Lite on xbox360 power supply (the biggest one) I never had one case where I need to wait for one "voltage cluster of batteries" to be finished before charging others.
I love your explanations....going to have to refer back to these when my son turns around and says 'when am i gonna use this science stuff in real life dad?!"
RC is such a great hobby for teaching science, engineering, hand eye coordination, even art if you enjoy painting up bodies. May even try and get him reading the manuals in chinese and by the time he's off to college he'll be a flippin' PhD! :P
I have a 24 volt 1700 watt power supply. I also have a isdt T8 charger. In the future I’ll be running two chargers off this power supply. My question is will this power source hurt the charger? I think output is like 70 amps but not sure. Is it possible to over power the input side of a charger?
Thank you very very much Joshua for this eye opener. I'm new with (LiPo) chargers and have already seen a few of your videos here on UA-cam. Most are pretty clear but this one left me with a question.
Does the max current rate of the source (ac-dc or battery) play any role...or if I may qoute you "which one comes first"? You mentioned that most chargers, at the time of recording, have a max current rate input of 14-16A. But what about max output current rate on the source side...
Example:
Source : DC 30v 9A(max)
Charger: 14A max input - 14A max charge current - volt range 10-32v.
Can the charger charge a battery at a charge current of eg. 10A (higher then 9A=max output current rate source)?
Greetings from The Netherlands
This is why I went straight to using deep cycle marine batteries wired in series or 24V+ (sometimes adjustable) switch mode power supplies the day I began using a 'real' hobby grade charger which required an external power supply.. Once that HITEC 50W charger wasn't quite enough when I stared to fly helicopters larger than
I have a M600 Toolkitrc 150W max input 28v 12a lipo charger. So its safe to use 26v 16.5 amp power supply??
ahh this takes me back to my car audio days when your buddys 2000watt crunch amp only had a 20 amp fuse and you laughed at him
I'm looking for a charger that can do 1s and 7s, and at a good price. I'd like atleast 10 amps if possible. Have any suggestions?
thanks
I have the Dynamite Passport P2 which has a DC input rating of 11-18V. Would one of those work?
Hey Joshua here I go again with one more doubt. By the way that issue with that similar isdt lipo charger that I told you about it is solved my local dealer send me another one brand new, thanks for the advice. Now I noticed that the lipo charger reaches 52+ degrees Celsius when powered with a 6s lipo battery much more than when it is powered from a 12v dedicated power supply. Can you give some explanation for that. Thanks once more.
My crosair computer power supply can puts out 35a at 12v, I can charge a 6s at 11a using a ISDT 500w
I use a Q6+ and a T6 Lite , both ISDT, from a Banggood 360W, 24V supply. The best thing is both these chargers show exactly how much they are drawing, in watts. I've never come close to 300W, never mind 360W. Even in all day flies, I can keep all my packs happy, without worry.
Keep up the good work J,B. 👍Hope your not having to much fun!!!! Lol👍🌞
Manufacturer should usually list the max input current from which you can calculate what is the minimum voltage required on the input to reach the max output rated power.
I couldn't find this info for your Q6 Plus, for my Q6 nano it was available tho.
Thanks Joshua for interrupting the quadworld's blastyness for our education!
And now get the hell out and have loads of fun!!
something else to consider. Some chargers work below 12 volts while others do not...
My ISDT T8 will not work under 12v. This can be problematic if charging off a lead acid AGM battery, as soon as it sags below 12v the charger may shut off. Which means charging 4s Lipos, nearing 16V at 5amps you will be pulling a lot more than 5amps from your 12v supply. As your source battery sags you will hit that voltage limit more quickly.
Wire in series and be on a 24v system and you are good to go. Pulling less amps from 24v while being able to not worry about battery sag on the input side.
I kinda messed up on my portable box when I bought my powersupply. Did a 12v 600w setup but I keep it pegged at 13.8-14v and on a 10amp output charge I see the power supply sag to around 12.6v. If I ever rebuild I will use a 24v input.
On the M8 toolkit charger I get over voltage error when plugged into 12V power.
isdt sc-620 is a 20A charger :). However max power can only be achieved with 24V+ PS.
I have a 12v 20a led psu and there is a knob to crank up the voltage to 14v. It supplies the desired 14a on the same charger :) Also it's important to use at least 16AWG wire not some crappy wire you find laying around. It cooks itself under that load and wont provide the those amps.
After watching the whole video, yes it only works if you are only charging 4s batteries.
