Me too not sure what’s happened 😅. Anyway, I used a low gauge cable and I replace it with better one in an enhancement video for the same project. Thanks for your feedback

What I can imagine is, he is holding that bzel with negative and positive terminals outside. negative terminal is already connected and is pointing downwards while he is trying to route cable through the positive terminal. I guess he touched with negative terminal a positively charged place on naked BMS.

or, the other way around. It is actually negative terminal he is connecting.

I guess so that’s what’s happened 😄 we must be careful when dealing with batteries

@@abdelbary8 true. Very nice video tho. I will use it to make my own battery to power up my sons e-quad. thanks!

Lithium advantage in storage capacity. its important to concern to choose the right cells with specs like discharge rate and the real capacity based on your application

Bangood, Aliexpress, Temu or Amazon

It will work as they are lithium ion batteries within the board max current

@@abdelbary8 That is what I thought. Thanks for confirming that.

You can use either 12.6v adaptor or multi cell lithium 3s usb type c board

Repairing lithium battery pack could be done by replacing the cells with new. There’s many tricks to refurbish/getting them alive back lithium cells but be careful as that’s risky

I agree with you, insulation paper used to isolate the nickel strips, Thanks for correcting me. Batteries and bms both are Chinese and need to do test on your own as I mentioned in the video. Anyway it’s working and FYI this battery around 1600mah only 😄
