I am back again still with no luck
I really can't believe it.
A set of cells is now dead on this new battery. I spent a lot of time to get these charged up, confirm they held. I installed a new board from battery space and they held for a bit. Now a week later, series 1 is at 1.3v and effectively dead.
I have no choice but to move away from this board now.
I followed fetcher's description for connecting B- | Balancing Harness | B+ but I am going to ask to confirm something more:
With a 13s 2p pack I am connecting the board in the following way:
Series 1 - I connect B- wire from board along with a balance wire to a tab at the negative pole of the series. There is other series connection at the negative terminal here.
Series 2-12 - I connect the series alternating positive and negative.
Series 13 - I connect the two B+ charge and discharge wires along with a balance wire to a tab at the positive pole of the series. There is no other series connection at the positive terminal here.
I am assuming all of this is in order because I don't get any crazy sparks and the batteries run.
At this point, I am really wondering if those boards are LiFePo? I just don't get it....
