Yes it is. But it'll be hard if not impossible to find a 12S balance charger. It'll be better just to use a BMS.

@@vuaeco Thanks for reply. I am thinking of making 2 packs at 24V independently can I connect both packs to make it 48v? How do you do that from the outside of the cell?

It's an ISDT 8S balance charger, cheapest 8S balance charger you can get on the market.

mines 26s and i wonder if the have to be seperated into 6s for my 6s charger. looks like he didnt seperate his, just bent it in half 7 and 6s still conected? i gotta know

@@williamwindex3890 He left the 6s and 7s connected. I think he can charge at the same time because he is using two separate chargers. I worry that if one was trying to charge two parts of a connected pack with say one of those dual channel chargers, then unless the grounds on both channels were independent, you could burn out a channel because the grounds of both parts would be at substantially different voltages.

Yep, when a cell gets hot, it's time it's gotta go. It might also bring down any cell parallel to it. The 100V LED meter wouldn't drain that much. You can use a single 18650 to power it if you have to. I would just install a switch and turn it on when I need to then draining power would no longer be an issue.

I have an Accucel 6 balance charger and it's been running for 8 years. I use it almost everyday. Besides the cooling fan which is now loud due to bad bearing (as expected because use it a lot), it has no problem. I would buy it again if I needed one more.

100W? :D

@@vuaeco I am new to ebike business. In the past I used emergency computer backup battery unit to charge the scotters 6volt battery. That work. Also I used Bosch tool battery charger to charge all kinds battery by hard wiring using refg copper pipe as connector. Somehow this Bosch battery charger that come with tool know how much Volt battery should be charge. It can charge battery from 9volt to 30volt. After watched so many your video last few days. Realized you have all kinda battery charger. I don't know exactly what each one does or what you are talking about with all electrical terms. Anyway, if I just want to buy one charger, which one to buy? Recommendation?

I'd recommend a Turnigy Accucel 6. It's cheap, easy to use, durable, and it can charge all kinds of batteries from NimH, NiCad, Lead Acid, and Li-ion... And most importantly, it can balance charge. That's the one you see at the end of the video where I was charging my 6S battery pack.

The orientation depends on how you hold your balance connector. Try like what I show in the video and compare it with your method. Don't trust the colors on the balance cable, they are all random.

yes i just checked itvaag 's video he said with flat connector facing down the negative will be on right so i changed leads over its ok

Yes, if the flat side faces down, the negative is on the right if the wires are away from you. If the wires are on your side and the flat side down, the negative is on the left.

I will once I have spent enough time on it.

exactly my problem - it obviously must ballance only the group of batteries. But the batteries within the group still are unballanced. It doesnt tackle the each individual cell anyways.. so wtf ???

@@magnetorsfour1612 all cells in parallel are automatically balanced. It is a basic rule. So when balancing you only care about balancing the group of cells together

A 14S balance charger is virtually non-existent. Or if there's one, it's gonna be very expensive. You don't have to completely split your battery into 2 pieces. You can just still connect balance cables without splitting it into 2 pieces. You can do 6S and 8S and use 2 balance chargers to charge it. I did this in my previous video right before this one.

@@vuaeco Thank you for your answer and for your excelent educational videos. Thumps up for you. I saw the video you mentioned and understand how you do it. Do you think i could balance wire my pack as you did and still use my BMS which i like to have because of low voltage cut off. My cells are old and therefore out of balance. I saw this video from a dude that made his own DIY 19 cell balancer. Have you seen his video and what you think about his project?

That would add more cost, time, and complexity to the build. Not to mention most BMS has reliability problem unless you get the expensive ones. Whatcha gonna do when your BMS breaks? That's another day wasted just to get it fixed and replaced. It's just another added component waiting to fail. Why is it so necessary when you already have a balance charger? Afraid of overdischarge? Get a volt meter. :D

it makes it simpler one plug to charge not 2 rc chargers thats why on my pack im running a bms but its only for charging so if it breaks I can still ride just not charge plus ill have spares.

Yesn't.
