I have JK BMS 8s with 2 amps active balance, it shows no errors when charging with epever solar charge controller even at 30 amp but start to show error CPU AUX anomaly when charge with PowMr all in one inverter solar grid charge controller even at 10 amps (same solar panels cause the problem when battery is charged with this stupid cheap inverter). HankzorBMS and PowMr aliexpress stores were not helpful at all. Has anyone came across this and how did they fix it? thanks
