- Some quick little tips to help people out there when it comes to charging Lipo batteries. I know there can be a lot of numbers and things to understand when it comes to batteries and it is important to get them right because Lipos can be dangerous in used incorrectly. Happy flying everyone. If you found this helpful leave a like so can help other people too.
Like what I do. Support and help me grow the channel at / uavfutures every little bit helps and will allow me to make more videos like this more often. Big thanks to the people who already do support the channel. You guys rock. Happy flying
EDIT: I accidentally said miliamp hours instead of amp hours at points in the vid, But im sure you get the idea : )
TIP: If you're using this charger (Turnigy Accucel-6 80W) to charge fat shark batteries you'll need to upgrade the firmware of this charger! You can't balance charge fat shark's batteries so you'll end up with an error by default. Here's the link to the firmware. hobbyking.com/... Download "ACC6 80W firware v1.13 patched to fix balance connect error" and follow the instructions inside!

Thank you so much! I am a beginner looking to get into the hobby and this is exactly what I was looking for.
Wooden chop sticks tap at a lower frequency than the plastic ones for less interference and a warmer feel. You made me smile, thanks a lot.
I got into fpv because of your channel. got a 5 in racer and a set of goggles. I'm having so much fun and I keep coming back for videos like this. my board just came in and I'm watching this to know what I'm doing. thank u so much for this channel. super informative and helpful. Currently my favorite
Enjoying your channel!
I have grown up with those chopsticks!
They have always been "the" preferred chopsticks over the fancy lacquer or plastic ones in our household for 50 years. Way better grip on your food! They also are just handy around the house for all purposes as you know!
Never mind the metal ones. Eating food in Korea is much more difficult than in Japan.
Can’t believe that getting into RC would open up a whole new world of unknown basics like lipo charging and frequencies and what not 🙂 thanks for the quick guide! Was very helpful. Found they ship the batteries uncharged for safety reasons
Just a little mistake, you said .1V difference per battery, but it is per cell, do on a 3s they can be .3v apart, and on 4s .4V :) having them closer is better of course, if mine are a little closer to the .4v apart I just leave them in for a few minutes before I start the charge so they balance. Also in the beginning you kept saying 1.4 milliamphours, haha. Quite a small battery ;) 1.4 amp hours. Just being nit picky, it was a great video and will help lots of people :D
thanks mate. yeah sorry about the numbers, but hopefully people got the idea
UAVfutures Yeah, it won't mess anyone up as you showed putting it in :)
I am not sure the voltage difference works according with the number of cells, whatever the number of cells of the LIPOs, i have always charge my batteries with 0.2V difference max per cell. Another important point for me is you have a LIPO with one bad cell, don't charge it in parallele with other LIPOs, there is a risk that this LIPO could damage all the other LIPOs.
ABMNS PRODUCTION It is by number of cells...but everyone has their own "standards" but you should never exceed .4 total for a 4S. Some people only charge at 1C, but I do 2-3 if I need them quick, so it really just depends on how much you know and trust about your gear :)
sorry still don't get this.
could be because I'm not English and it will not get into my fat head. lol.
Please bare with me.
I'm talking 4S here.
So is it .4V difference per BATTERY or per Cell?
let's say i have Lipo's perfectly balanced. one is 14V and the other 14.4. that's a .4 difference per LIPO. but only .1 per CELL.
Or is it .4 difference per Cell of ALL the lipo's going to be charged in parallel.
So let's say between 3.5V and 3.9V between cells.
That's a .4 difference.
Because then the voltages PER LIPO can get between 14V and 15.6. If they came down perfectly balanced and the 14V Lipo is 4x3.5V and the 15.6V battery is 4x3.9V.
you get what I'm saying?
So can somebody please clarify this before I burn down the house with me, my wife my son, and the cat in it :D
I'm a complete noob in the drone/fpv hobby and I appreciate your videos and the info you provide! (I do read the comments too!) Keep up the the good work Stew, and thank you!! I've been more inspired to get into the hobby because of your videos than any others on RUclips!!
Thank you. I have watched a stack of vids on this and good lord, it feels like no one can just say what the heck to do in plain English. This vid made it plain enough that even I could understand. Oh also, it was your $100 builds that got me interested on race drones, rather than the camera drones I was flying. Thanks again!
I can't stress how thankful I am for your videos. They've really helped me along the way. Even with becoming comfortable with soldering on boards. I appreciate the help and knowledge!
You made this so long ago, But its still helping many like myself. Your a legend mate. Thanks from Pete.
I feel like no one ever tells this guy good day back. So good day UAV Futures :)
thanks
Ahh Mr. Big shot and his nice chopstick. Great video Stu! I always count on you for direction. Now I can safely parallel charge my 450mah whoop batteries. Thank you.
This was a great little refresher from being away from the hobby for much too long. I got a good chuckle when you brought up the chop stick and laughed my ass of when you started giving specs :)
Thank you for the super clear explanation! I already ruined 2 battery's and a drone because I'm a beginner.. should have watched this video first ;)
Even on a screwed up day I cant hold myself when you start your video with your typical awesome Aussie welcome ..😄👍 best regards from Germany
Haha stew you crack me up.. great vids and nice chop stick! I been wondering how many of those you go through, and strangely enough I feel satisfied now haha, happy flying!
Loud and Clear for beginner like me!
now I lay 24 batteries out at a time... before I watched Stu and this video, took all day to charge 8 batteries... gamechanger
Awesome tips m8 but allow me to comment on something which might get you into a revised already awesomeness. You can equalize the batteries voltages by just letting them rest on the parallel board (main leads and balancing connectors). so if you have one 3s bat with 3.70/3.71/3.70 and a second one with 3.4/3.41/3.42 within a few minutes resting them on a parallel board, both batteries will have similar cell voltages and ready to be charged in parallel. (ps: of course I am talking for same batteries, cells, capacity and discharge rate) Thanks again for your video. keep em coming. I really enjoy your channel!
good to know, thanks
Thanks buddy! this video really helped! I love your channel! I just got into FPV, flew my 1st race drone the other day after training with the DRL simulator! It was the most awesome experience ever, got my self a QQ190, its a beast! thanks again! keep posting! ur killing it!
Hi folks,thanks for great video.
just my 50 cents of info to improve this guide.
There is few bad scenario still exist when you connect all this cells in parallel,each and
every pack & cells have different internal resistance so the consequences might be harmful because of next reasons:
1- not equal current flowing in each cell (you better not charge whole pack at its 1c,for example 5 packs 1000mah each not so safe to charge at 5 amps),safest side is to charge at C rating of 1 pack which is far over protection but u decide.
2- if you have one bad cell the balancing process might take way more time and potentially damage all of your packs at same cell number.
so be careful and better of all write on each battery pack it's cell internal resistance and try to match packs as much as possible.
BR all.
Thanks for your advice I did it on 2.6amp and gave up with the idea of taking the car out in the end so I will try 4 amp now 👍🏻
I've been charging a 2.2amp battery at 1 thanks. goodbye 3 hour charge time😂
Hey Stew, thanks for this video mate, certainly gonna help me when i start buying and charging 3-4s batteries. Glad I watched till the end! You are such a funny guy!
another brilliant video. I would have assumed that a parallel charger was a charger, so would have had to order a charger after it arrived 😐 big learning curve 😊
thank you now I'm not scared to charge my batteries. good tutorial.
Great video thanks!! Ordered my lipo batteries yesterday, shame they will be here a couple of weeks after my quad. At least I know how to charge them correctly now.
Been watching your videos .and I'm now buying all the parts to build a quadcopter. Thanks man your videos are awesome and really helped me understand this stuff. Thanks !
Great video. I never charged my LIPO at 1C lol Always 1/2C. For me one crucial point when charging in parallel is to make sure that all these LIPOs have healthy cell. One LIPO with a bad cell can damage all the other LIPOs.
Thanks a ton for sharing Stuart and have a great week
thanks. Great point about the cell
1/2c is a bit under kill. 1c should be fine if you want to keep you batts in good shape but I don't really think it would hurt the cell to charge them at 1 1/2c but it might reduce the Mah you can put back into the cell. I charge 3 4s SMC 37a 1300Mah packs at 5.3 amps but I should charge them at 3.9amps because that's 1c. If your in a rush to fly charging them normally or at 1 1/2 shouldn't really hurt them at all. If you have a slightly puffed/damages pack with a bad cell then definitely charge it separate.
Crøblë FPV There is nothing under kill, LIPO had been designed for delivering power not storing it :)
The less C rate you use when charging your batteries, the more longer and the more better they will perform because you don't hurt the chemistry inside them like you do when charging at higher C.
Of course you have also to be careful and do not push them beyond their limits while discharging and you should also respect the basic rule of putting them on storage state when not using even for a short period.
Thank you for the video, I know it helps a lot of people that is new to the hobby. I will recommend this video to a friend that is just getting into the hobby :)
fantastic stuff as always. particularly enjoyed the chopstick review! 😁
lol
great video Stu! I just throw my batterys onto the parallel board with no balance leads to balance Eachothers voltage for 10 mins then I connect the balance leads for another 10 mins... that way when I go to charge them again they are all the same cell voltage... I typically do that at the end of a day of flying (useing the same methods that you use for charging e.g. same cell count and mah ratings)
Nice beginners vid. Thanks. Im not into the RC hobby, I'm in the live music industry and we're starting to see LiPos in our world. I've been warning co-workers about the dangers of improper charging and I dont think they get it...
lipos are scary.
Can’t I just cut the xt60 plug off and shuv the leads in my house manes
yeh bruv that'll work just make sure you chuck open a beer and watch from outside in the garden on your folding chair ye? don't want cha dead mate
Blake FPV sure u can!!
Psychonaut hahahaha 😂
Lmao
first check the amperage by short-circuiting the battery with your multimeter.
Best class I have seen about charging batteries. Thanks!
thats a nice chopstick!....lmao!
thanks
u sound triggered lol ;)
Chopstick was the best part
It's almost 2018, USE A FREAKIN LAZOR!
Naw. I like the chopstick. Requires no batteries to charge! :)
This helped so much!!!. Im just getting more batteries and beginning to need a multi charger. Grreat video Stew!!!
Great info im using a bunch of chargers for my lipos so your vid has helped me out big time!
If this were my video, I would've mentioned to not leave the batteries alone while charging, and probably recommended some sort of LiPo-crarging-pouch, as those greatly limit the possible damage of LiPo explosion. Also, the craging area should be clear from flammable materials. Friend of mine survived from LiPo explosion with black floor and little shock, but if there were anything flammable around, the result would've been a lot more sad. That being said, your video told a lot of important things many would never figure out by themselves.
1.4 amp hrs. not mah. it would be 1400mah /1000 =1.4 ah Not huge but a tip for newbe
Dude thanks lol how do you know when the batteries are charged or need charged? I dont have a cell checker I just have a multimeter. The battery said it's a 4s 14.8v but the read says it's at 15.44v
Thanks for the info. Turns out I figured it out right but better safe than sorry!
The chop stick specs at the end cracked me up lol 😂
Nice to see someone doing this. Well done! 😃
cheers dude, got a parallel thingy mabob but havent got around to using it as i wasnt sure about the level each lipo should be or if it mattered or not. so now thanks to your vid i now know the answer.
:)
keep up the good work.
if you have one of those smart battery cell checker that can also balace your lipos with you can plug all your batteries into the charging board and plug the board into the lipo checker and balance all your bateries together so you dont have to sort them per voltage👍
You are a great tutor. Best of luck.
the chop stick was very informative lol.
Well, I was watching this video and my question is how you plug your power sistem or your charger, I don't know how to do it because I don have the regular cord for the power or do you have any video talking about that
These Turnigy chargers have a handy voltage tester that can be found on the BATTERY/PROGRAM level of the menu, which shows all the cell voltages on screen at once, when you connect the balance plug. It's a bit quicker than using the portable tester and having to wait for it to cycle between cells.
Love the chop stick part.
Thank you so much for the info. I just bought some and didn't know anything about them.
Great info, thanks alot...looks like I'll be doing some parallel charging from now on!
Such a quick and precise video! Thanks for the upload :)
For anyone wanting to know the math, remember P = A * V. So you need to multiply the voltage (11.1 here) times the amps to figure out the power draw. His charger was only an 80 watt charger, so 11.1 amps * 7 amps would draw 77.7 watts of power. That is probably too much for this charger, I have heard you should always leave 20% headroom for any power supply. So for 80 watt charger, probably don't put more than 64 watts through it.
Aaron Writes Code its P=U*I
My one batter is 1500ma 75c and other is 1550ma and 95c is it ok to parallel charge both same time?
Love your channel ! miksing mah and amp sometimes.. you should do a video where you talk about how to match charger and power supply. I think many people is miksing thing up there..
Just a tipp: Lithium cells don't like high charge rates. The oxide layer on the electrodes inside the cells cloggs faster with higher charge rates and so the cells "degenerate" faster. Just charge them at ~0.5C, that's actually the recommended charge rating from the manufacturers (Just take a look at Datasheets from LiIo/LiPo cells from LG Chem, Panasonic, Sanyo (sony), Samsung...).
TL;DR: The lower the charge rating, the more happy the battery is (:
Excellent video and g'day from Canada :) Do you know or have you ever tried using the balance board to place multiple batteries in storage mode? Often when I come back from the field and I have multiple batteries, it would be so much easier if I could put 6 batteries at a time in storage mode, just wondering if the balance board would work safely and properly for that as well. Thanks again for your passion and dedication and taking all the time and effort to do these great videos. Happy flying! Cheers, Scott
This is one of the most helpful videos out there. Thank you!
Hey Stu - great content as always but please let your viewers know that the current AC version of this charger will not charge Fatshark batteries. It does have a CHARGE mode (as opposed to BALANCE) however it still requires a balance lead :( I already went through this and had a friend suffer through the same. The DC version seems to have different firmware that works OK. Instead the iMax B6 will get the job done and is AC powered which is preferable for us n00bs.
it charges my fatsharks fine. but it might be the newer fatsharks it cant charge
Thought you were running the DC version on the video. My bad.
MojoPapi FPV f N DC commonplace bin mignon yyjdo c know hgfo
Thanks for doing this video.
thanks for watching and your support
Charge option and Fast Charge will also balance the battery when balance wires are plugged
Great videos and well explained!! can't wait till I can afford my first drone.
Thank you for your videos!!
Any chance you can do an updated version of best lipo chargers? Looking to buy a second one I'm currently using imax b6 thanks
Cheers great help. I was just chucking all the same batteries on a balance charge with out checking the cell count😓
be careful lol
You can safely charge at 5c occasionally. I do it about every 3rd cycle or so. So a 1000mah 11.1 3s can charge at 5A. full charge in 12mins
Looks like the iMax B6 has the same firmware. I ended up charging my first time using the iMax manual. Argh, that was painful. Your video helps clear many questions I had. Love your style, keep up the great videos. Sub'd!
Thanks for the vid , just ordered one of those balance boards..... now I know how to use it , great review 👍 and now I know what weight chop stick to use lol
lol glad to help
Silly question but how do you know when it's fully charged 😳
it will beep
it will do this
“EEEEEEEeeeEeeeeeeEeeEeEeeeeeEeeeeeeeee”
@@dj3j944 Ohw shit i heard the exact tune in my head xD
After watching your Beginners guide to charging LiPo batteries + parallel charging video, I thought, is it OK to storage charge multiple lipo packs, using a parallel board following the same rules for parallel charging and simply selecting "storage mode" on the charger ??? Essentially, can a parallel storage charge via a para board ?
Thanks, your videos are a must see
I want to put two batteries in parallel. If only one of them is connected to the charger, will the other battery charge too?
best drone tutorials for newbs like me xD
Thanks for the awesome video! Just getting all my parts in a Monday so this helps a lot. Think you could make a video about the different charging modes and when to use them? Charge, discharge, storage, ect...
just use balance for all charging, and storage for when you are not going to use them for a long time. e.g. more than a week. thats it. simple : )
I have those 65C 1400mAh multistar batteries in 4S. They get the job done and are reasonably cheap.
Best chopstick review ever! 16:52 :)
For me. I will be charging (2) 7.4 2S 5200mah 50C batteries. My set up for the amperage will be 10.4A for an hours charge for the two. I am better off not parallel charging because I be charging two at 5A for 2 hours Either way I still get done the same time if doing one at 5.A, or two at 5.2A? I will be needing a battery checker. thank you
if charging is through the skinny wires, then why do we need to hook up the 2 thick wires?
what is the safest discharge vaultage for a 7.4v battery? is it 3.7v or 3v for each cell?
Thank for all your videos you have educated me and saved me a lot of money
Hey Love your drones on a budget videos,which are great!!!Just was wondering could you do battery's on a budget video.. I'm shopping around starting to realize that is one of the most expensive things. (If you want atleast10) if you could that would be great..keep it up ur the man. Have a GOOD DAYYYYYY!
If you are in a rush, most chargers have fast charge... Charges to around 95%, the last 5% or so takes along time.Also if you have the time charge at 0.5C make the battery last alot longer.
I would recommend buying a parallel board with replaceable fuses just as an extra safety precaution
good tip, as long as the fuse is small and will actually blow before the battery
What power source is the cord on the left of the Accucell plugged in to?
I have the same question. I ordered this exact charger and it doesn't come with that black cord with the female xt60. Help us please 🙏
Great video Stu. I now have enough batteries, that I need to a parallel charge board. I love your channel and I always get a lot out of it. Thanks. I do have a couple questions. First, where did you get those XT60 connector covers? Also, I saw a video of yours, where you showed a really cool USB charger deal that you connected to one of your LiPo's for charging in the field. Do you recall, what I'm referring to and if so, which video was that? I would love to pick one up. Thanks again for all the content. Your channel is my favorite.
great video. I had no idea how to do this when I first started.
Question: For years I have had RC scale off road trucks that required the lipos to charge using both the regular connector and the balancing connector, but recently I started flying fpv quads, and now my fat shark battery charges using only the power supply and then I have a Rise vusion battery that charges using only the balancing connector.. WTF?
I know this video is a few years old. Is the Turnigy Accucel-6 80W | 4 Button still a good charger or are a lot of folks using something different now. Just getting into FPV...thx!
Thanks, mate! Nice video and very professionally done!
Thank you for this video. Helped me in ordering charger for FPV setup i ordered earlier today also which what was based you your recommendations.
I can't find a charger that'll charge at 25.9V for my lipo they all say 2-20V what do I do?
I also recommend covering the deans connector on the board to avoid accidental shorting.
I have 2 huge gold banana plugs sticking out of my charger (1cm apart) for years and I never shorted them out (it actually makes me extra careful when charging batteries)
newbie here..what happends if accidentally plug one of the balance leads the wrong way and short the board? can I still use it?
it won't actually fit the whole way in, but it might make a small amount of contact which will result in a short...smoke, fire. you know.. the good stuff : )
+UAVfutures .. I was able to make a little contact and I did get the magic smoke. does that means the board is no longer good? I haven't used it since then but I've been wanting to is just that the idea of a fire getting out of control doesn't sounds fun
unfkwthabls
That sounds quite bad for the parallel charging board I wouldn't use it outside my line of sight anymore (it might also be a good idea to measure it thru to make shure there isnt an internal short or resistance)
The charger will probably be fine (if it is a quality hobby charger)
How to charge heng long stock battery?
Thanks for these videos geared towards the rest of us👌😉🖒
If i got 2 pack with different C rating, for an example a 4s 1300mah 75c and a 4s 1300mah 100c. Am I still able to parallel charge them or should I only parallel charge packs with the same C rating?
Can you link the batteries/chargers/charging board etc. you used in the video?
Very educational man ....thank you
Lol that chopstick review was amazing! Does it run 5s?
4 gram "Chopstick" I'm very impressed
Thanks for the reminder
I don't understand how the Charger can measure 6 times 3cells (for a 3S-pack)? It would need a 18pin-balance-port.....or how does that use?
I have a problem why when i press start to charge my battery it keeps saying cell error voltage invalid
