Good to know! So without balance, the BMS is really just monitoring, but actively keeping cells in balance?

Update... I was able to find a new BMS on Amazon with the same balance connector as the OEM Blix one. However, it is only 15A and didn't have on/off switch support. Soldered the B-, P-, and C- leads and presto... 54.2v at the discharge port. So it was a bad BMS. Thank you @amberwolf and...

I'm pretty sure the on/off switch is wired in series with the thermal switch. The switch has two yellow wires. One is soldered to the board adjacent to the white lead from the thermal switch (shown in photo). The other is connected to the second white lead on the thermal switch with black...

Hello all - thanks for all the help. So I have new meter with x.xx accuracy with brand new batteries. I took all the readings at the balance connector while it was disconnected from the BMS. All cells read 4.18 or 4.17 except one, which was 4.16. I also did what @docw009 recommended and took...

Is something like this helpful for the charge/discharge to get the cells in balance? Amazon.com

I have a Milwaukee meter that has autosensing voltage (AC/DC). I'll pick up a cheap meter that is more sensitive and has manual range. I do have wire, connectors, soldering gun, etc. I'm fairly handy. Have done auto electrical work.

Thank you for the response. Yes, I'd be willing to try. I have good access to the sides of the pack so would likely charge/discharge at the balancing lead attachment points. My multimeter is only good to 0.x - should I get one that measures to 0.xx? Any instructions/advice would be appreciated.

Hi - newbie here to the forum. I did search my issue and definitely got smarter, but still need some guidance. My GF has a Blix ebike and she didn't charge the battery at all this past winter. The battery does have an on/off switch and it was left off (which I guess disconnects the BMS so it...
