In case the BMS goes into protection mode due to over-charge, over-discharge or unsafe operating temperatures, please switch off the battery and wait
for 2 seconds. Then, switch the
BMS to “ON” mode and wait for 10 seconds. Please make sure the unsafe conditions are cleared, then the procedure
of restarting the BMS would make the battery pack ready for charging / discharging.
