Hello experts!
I am new. Do you think with the below data that my next step in determining why my LVC keeps tripping the BMS while biking using my old battery I picked out of storage is because of a damaged/old cell, or because it needs to balance longer? Should I let it balance longer before riding again? Should I let the battery sit off the charger and measure again tomorrow to see if any cells drop significantly?
Battery: Panasonic 37v 9Ah, from a e-Moto Velocity 2.0.
BMS: KL3688CL3
Volt at battery output: 42V
Charger output: 42.3V
Days on charger: initially 2 days, then a bike ride where system shut down several times under load but rode 12 miles, and then another day on the charger (24hrs). The following is the result after the 2nd session on the charger.
Cell volts:
1: 4.27
2: 4.27
3: 4.17
4: 4.17
5: 3.89
6: 4.27
7: 4.27
Any input is welcome, I want to see if I can fix it vs. spending hundreds... obviously group 5 is pretty low...
