Hi all,
I have a JK BMS on a 14s pack leaf pack.
The cells all populate correctly on the app, but once the pack is under any load over 5 amps one cell will show crazy voltages, seemingly at random. Using a multimeter I have verified that all cells stay balanced while discharging. I am using a programmable load and slowly creeping up the discharge. The JK app starts displaying wrong voltages above 600w, and shuts off discharge.
Pack wiring and overall setup seems fine, and has been cycled recently. It had a smaller dalybms, but was upgraded for the higher recharge/discharge rate. I’ve rewired and rechecked the bms leads a few times, definitely roast it if you notice something that could be improved. Red leads are for the JK, yellow leads are unused for now.
Thanks for any advice
