Hello everyone, a new boy to the forum so be gentle with me ! I have built a 36 volt lithium ion battery using the tried and tested 18650 cells and the solderless Vrusend kit, I also obtained a B M S of suitable voltage and amps and here is where I have come unstuck.
Those Phase wires ! I must admit that having watched various videos on How To Wire A B M S, I feel most uncomfortable when soldering the wires to ( what I believe ) are the correct cells I just don’t feel I’ve got it right.
Without connecting the battery to my eBike the B M S started to get hot so I immediately pulled the multi plug off and let things cool down ! I know the very first Black wire goes to the battery Negative but the sequence after that I find confusing ! The next wire after the Black is Red which is then followed by a Yellow wire and then another Red and so on.
I am pleased with the battery and it shows 42 volts and works very well on my ebike with the B M S disconnected, the battery is made up of 30 cells with 3 cells across, well that’s my rant over and I would be very grateful to anyone who could help with my confusion ! Cheers everyone Harry Morris.
