Hi
I have 52v shark battery. The case broke and it got wet inside and then the bike would shut down after a few minutes of load. I took it all apart and found 2 blocks of 5 cells that were showing 3volts the others all showed 4.3 or 4.4
So I have changed the cells but when I charge it up the new blocks don’t get charged up which I assume is correct since 12 cells at 4.4 is already getting me close to the 58v cut off
Because of this when I put load on the bike shuts down after a minute or two.
I am guessing this means the bms can’t balance such a big difference in voltage between the blocks- does that make sense
If so I am planning on bypassing the bms to be able to run the other cells down and hopefully then when the bms is reattached it will be able to balance them as they should be closer together. Does that make sense or should abms be able to balance it anayway and it just needs a new bms?
Thanks for any help
