TROUBLESHOOTING

The LiFePO4 battery module is an extremely reliable battery module that provides
greater useful life than comparable 12 V lead-acid batteries� Despite the high relia-
bility, you may encounter situations where the battery module does not operate as
expected� These situations are typically the result of misuse, abuse or a non-opti-
mal operating or storage environment� This chapter details potential issues you may
encounter with and the appropriate troubleshooting procedures�
CHARGER TRIPS USING CC & CV
Problem
chargers trips when charging the battery module� This is due to the low impedance
of the module creating a current inrush�
Solution
Reset the charger and try again�

TERMINAL VOLTAGE ABSENT OR LOW

Problem
Using a multi-meter to check terminal voltage shows the terminal voltage is low� Possi-
ble causes for this problem are:
• The voltage of a cell within the module dropped below 2�3 V, causing the micropro-
cessor to enable under-voltage protection�
• The module overheated, causing the microprocessor to enable over-temperature
protection�
Solution
To resolve situations where terminal voltage is absent or low:
1� Allow the battery to cool and then recheck terminal voltage�
2� Connect the battery to a charger to wake the battery and recover terminal voltage�
Depending on the module's voltage and state of balance it may take up to 48 hours
to completely charge and balance the module�
