battery cell group will be closed to shunt the charge current around the highest-voltage battery
cell group through the bypass resistor until the voltage dierence drops below the set value. To
avoid excessive energy loss, the battery cell balancing is only performed during the charging
process.
Troubleshooting
If any problems occur during the battery operation, please refer to the following instructions or
contact us for assistance:
●If the battery is unable to be activated with a charge/discharge current greater than 1A or the
battery is activated with a resting voltage below 10V, the battery may have been severely
overdischarged due to self-discharge or parasitic loads. Please revive the battery with a
battery charger or charge controller featuring lithium battery activation or force charging.
●If the battery voltage is 0V, the internal fuses may have blown due to severe over-current.
Please contact us for assistance.
●If the battery shuts o due to undervoltage protection, please disconnect the battery from
loads and charge the battery with a current greater than 1A as soon as possible.
●If the battery cuts o the charge current due to overvoltage protection, please disconnect the
battery from the charging source and discharge the battery with a current greater than 1A as
soon as possible. If the problem persists with a lithium iron phosphate compatible charging
source and the correct voltage setting, please rst reduce the charge voltage by 0.2V~0.4V
to balance the battery cells for 6 hours before attempting to fully charge the battery again.
●If the battery temperature gets too high/low during the operation and triggers the high/low
temperature protection, please disconnect the battery from the charging source and/or loads
and cool down/warm up the battery. The battery will automatically recover from the high/low
temperature protection and continue operating.
●If too high a current passes through the battery and triggers the charge/discharge over-current
protection, please disconnect the battery from the charging source/loads as soon as possible.
The battery will automatically recover from the charge/discharge over-current protection after
1 minute. If the charge/discharge over-current protection is triggered 3 times in a row, the bat-
tery will no longer recover automatically. Please discharge/charge the battery with a current
greater than 1A to recover the battery from the charge/discharge over-current protection.
●If the battery is shorted and triggers the short circuit protection, please remove the short cir-
cuit as soon as possible and charge the battery with a current greater than 1A. The battery
will automatically recover from the short circuit protection.
