Trouble Shooting Steps                                                                                           

1 Problem determination based on:
1) Whether the battery can be truned on.
2) If battery is turned on, check the red light is off, flashing or lighting:
3) If the red light is off, check whether the battery can be charged/discharged.
2 Perliminary determination steps:
1) Battery cannot be turned on, switch on the lights are all no lighting or flashing. If the battery extemal switch is ON, the RUN light is flashing, and the extemal power supply voltage is 48V or more, the battery still unable to turn on, please contact distributor.
2) The battery can be turned on, but red light is lighting, and cannot be charged or discharged, red light is lighting, that means system is abnormal,please check values as following:
3) Temperature: Above 50ºC  or under -10ºC, the battery could not work.
Solution: to move battery to the normal operating temperature range between -10ºC and 50ºC.
4) Current: If current is larger than 100A, battery protection will turn on.
Solution: Check whether current is too large or not, if it is, to change the settings on power supply side.
5) High Voltage: If charging voltage above 54.75V, battery protection will turn on.
Solution: Check whether voltage is too high or not, if it is, to change the settings on power supply side.
6) Low Voltage: When the battery discharges to 37.5V or less, battery protection will turn on. Solution: Charge the battery for some time, the red light will turn off.
Excluding the four points above, if the faulty is still cannot be located, turn off battery and
repair.
