Brilliant, 7 years later and still the clearest explanation how to wire up a balance lead.

100% I hate other videos, this is the clearest by far. None of the usual jargon or nonsense about your cat or dog. Loved it!

[wyrick]

This did make more sense to me than most videos, for whatever reason. Thanks KTW.

Just wanted to say thanx for the info. Made myself a 4s today and without your help wood be lost on the balance lead hook-ups. Keep doin what your doin for us newbie's!!!

Really great tutorial! This is the exact info I needed to do my DIY 3S 18650 balanced battery. Thanks a lot!

Great explanation on how these leads get wired. I'm old school NiCd RC fellow. I'm new to the Lipo scene. I was recently manually balance charging LiO 18650 cells in some Milwaukee packs which have sat for years unused, but new. I have a 4 cell (individual charging slots for 1 cell each) charger from the vape/flashlight market. I made some cell adapters to place into the charger with some test leads (j-hooks) to attach to tabs on assembled packs. The goal being to charge each cell individually with each port of the 4 port charger. I used this successfully to bring cells up to 4.2V each. However, I was only able to use one charge bay, and do it one cell at a time. I bought a different 8 cell charger (for loose cells), but it would fault out when more than one cell was connected. I made a bunch of blank cells with wire leads to place in charger bays. I'd like to try to use them all at once, as I have large 12ah tool packs I'd like to bring into balance. Would using diodes maybe help? I'd like to avoid removing tabs. Should I just break down and buy a hobby balance charger? lol I actually have a lot of 4s, 5s, 7s leads from other projects.

Simplicity is the key! Most of us, trying to make some simple battery stuffs is very usefull this kind of video. Great, Like!

[MrsRabbit]

Thank you! This is exactly what i was looking for.

It's better to use correct cable colors, black for minus and red for plus, so it's easyer to see how to connect the balancer connector to the charger ect.

Thank you very much for this excellent video .
Could you please help me with my tenergy tb6b balance charger? I have lost the balance connectors and i need to charge three 18650 cells just like the video.but i don't know if i need to connect just these four cables ? Or the two red and black output port also?
Thank you for your help

You are a very good teacher! Well done! Kudos to you sir!

TY I just wired up 2s3p on imax b6 . I have 2 battery packs done now for ebike light. First balance was 4.2v and 4.11v and it brought them back in spec 4.2v 4.2v.

I heard both sides of this story from many people and although this works it less accurate because the leads are supposed to be far right is directly connected to negative and the rest go to the far positive end. But this works for me as well. Why I bring this up is because you can tap off of each of the batteries while connected in series by connecting a wire to the first battery positive and negative or connect to the first battery negative and second and the second battery positive and you will get 7.4v then connect the negative from the first battery and the last = 11.1v which leads me to believe the leads go to the far most positive and also leads me to believe there's a better method and it works perfect every time... The batteries that are wired in series will never balance out on their own so what I do is charge each battery pack individually... On a 3S I use a MPPT to charge each so I would use three separate isolated from the others by using three solar panels and they shut off when each reaches 4.2v and 12.6v total but as soon as I start to drain they start to charge and you can do this using 3 - 5v solar panels and 3 - charging modules... You can also do this by using 3 wall phone chargers connected to 3 TP4056 and it works, if you don't isolate each TP4056 by using 3 separate sources of power the chips will fry. Something to toss around.

Thank you sir, this answered my question exactly :)

Im going to get into soldering and make my own charging squids :)

[xadionwc]

can you do a 3s2p? exactly the same video but with 1 additional battery on each parallel.

[jokdigitalvideo]

Just what I needed thanks a lot .you have a new sub.

[andrewadams]

This perfectly explained what I needed to know, thank you!

[fespinosa]

Great video!!!! Thank you...please make more.

[TIMSOFNVISHOUS]

Can you do a video of how to connect a balencer lead from a I charger x6 to a battery

[brucetaylor]

Nice video mate, very clear and a great tutorial. Well done!
