8/10

CAUTION
If the ambient temperature is outside the operation range, the battery pack stops operation to protect itself. The optimal temperature range for the battery pack to operate is 0 to 50 . Frequent exposure to harsh temperature may deteriorate the performance and life of the battery pack .
5. Trouble Shooting Steps
5.1 Problem determination based on: 1) Whether the battery can be turned on or not.
2) If battery is turned on, check the LED light is off, flashing or lighting.
3) If the LED light is off, check whether the battery can be charge/discharge or not.
5.2 Preliminary determination steps: 1) Battery cannot turn on, switch on the lights are all no lighting or flashing.
If the battery external switch is on, the LED light is flashing, and the external 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 charge or discharge. If the red light is lighting, that means system is abnormal, please check values as following:
a) Temperature: Above 50 or under -10, the battery could not work. Solution: to move battery to the normal operation temperature range between -10 and 50.
b) Current: If current is greater than 150A, battery protection will turn on . Solution: Check whether current is too large or not, if it is, to change the setting on power supply side.
c) High Voltage: If charging voltage above 29.2Vdc(24V system) or 58.4Vdc(48V system), battery protection will turn on. Solution: Check whether voltage is too high or not, if it is, to change the setting on power supply side.
d) Low Voltage: When the battery discharges to 22.4Vdc(24V system) 44.8Vdc(48V system) or less, battery protection will turn on. Solution: Charge the battery for some time, the LED light turn off.
9/10

5.3 The battery cannot be charged or discharged 1) Cannot be charged: Disconnect the power cables, measure voltage on power side, if the voltage is 25.6~27.0Vdc(24V system) or 51.2~54.0Vdc(48V system) ,restart the battery, connect the power cable and try again, if still not work, turn off battery and contact distributor.
2) Unable to discharge: Disconnect the power cables and measure voltage on battery side, if it is under 22.3 V or 44.5V, please charge the battery. If voltage is above 24V or 48V and still cannot discharge, turn off battery and contact distributor.
6. Emergency Situations
1) Leaking Battery If the battery pack leaks electrolyte, avoid contact with the leaking liquid or gas.If one is exposed to the leaked substance, immediately perform the actions described below . Inhalation: Evacuate the contaminated area, and seek medical attention. Contact with eyes: Rinse eyes with flowing water for 15 minutes, and seek medical attention. Contact with skin: Wash the affected area thoroughly with soap and water, and seek medical attention. Ingestion: Induce vomiting, and seek medical attention.
2) Fire NO WATER! Only dry powder fire extinguisher can be used; if possible, move the battery pack to a safe area before it catches fire.
3) Wet battery If the battery pack is wet or submerged in water, do not let people access it,and then contact an authorized dealer for technical support.
4) Damaged Battery Damaged battery are dangerous and must be handled with the utmost care. They are not fit
for use and may pose a danger to people or property. If the battery pack seems to be damaged pack it in its original container, and then return it to an authorized dealer.
