BATTERY RAPIDLY DEPLETES ENERGY BETWEEN CHARGES

Problem
The battery module rapidly depletes its energy between charging� Possible causes
for this problem are:
• The battery pack is out-of-balance�
• The battery pack has reached the end of its useful service life�
Solution
To resolve situations where the battery rapidly depletes its energy between charges:
1� Use a CC & CV charger for 48 hours to balance the battery packs cells�
2� Replace the battery pack�

BATTERY CURRENT DISAPPEARS WHEN CHARGING

Problem
Battery current disappears when charging� Possible causes for this problem are:
• The battery overheated, enabling over-temperature protection�
• The battery pack is out-of-balance�
• Charger voltage is too high�
Solution
To resolve situations where current disappears when charging:
1� Allow the battery to cool�
2� Use a CC & CV charger for 48 hours to balance the battery packs cells�
3� Reduce charger voltage to 14�6 V or less�

VOLTAGE DROPS ABRUPTLY

Problem
Battery voltage appears constant, then drops abruptly�
Solution
This is normal for this product� Constant voltage throughout the batterys SOC ensu-
res maximum usable life� Once the voltage of a cell within the module drops below
2�3 V, the module's circuitry enables under-voltage protection, which creates an
open circuit
at the terminals�
