I have a JK-B2A8S20P-H on a 2P4S battery assembled from CATL 200Ah LiFePo4 cells. Settings as per Andy’s Off Grid Garage video on this BMS. Running for about a month now as the 12V house battery in my motorhome, completely separate from the 24V truck system.
All good - except the BMS randomly crashes when the app is opened.
What do I mean by crash? When opening the app, the BMS does the initial two beeps then tries to reboot. It shuts down the battery and gets into a loop, beeping and rebooting every few seconds - now over 1300 reboots! While in the loop the BMS won’t respond to the app or the on/off button.
Crashes are usually early in the morning with little or no charge from the solar controller and very light loads, battery 70-80% charged, 13.2-13.3V. Cells stay within 0.004mV even with balancing off.
What could possibly be causing this?
Is anyone else experiencing this problem?
