Why is my LiFePO4 battery not charging?

Discover possible causes and solutions to maximize performance and lifetime of your LiFePO4 battery. If the battery won’t activate and allow charge/discharge over 1A, severe overdischarge is likely. Self-discharge or parasitic loads can deplete cells below 10V. Use a lithium battery charger on activation or force charge mode to revive.

What happens if a lithium battery won't charge?

If the battery won’t activate and allow charge/discharge over 1A, severe overdischarge is likely. Self-discharge or parasitic loads can deplete cells below 10V. Use a lithium battery charger on activation or force charge mode to revive. The battery management system (BMS) cuts off discharge if the voltage drops too low, preventing cell damage.

How do I fix a battery that won't charge?

1. Disconnect the battery from the charging source. 2. Reduce charge voltage by 0.2V to 0.4V for 6 hours. 3. Attempt to fully charge the battery again with the correct voltage setting. If the problem persists with a lithium iron phosphate compatible charging source and correct voltage setting, repeat the above steps.

Why does the state of charge not increase/decrease fast enough?

State of charge does not increase/decrease fast enough or too fast when charging/discharging. This can happen when the battery monitor thinks the battery is bigger or smaller than in reality. Check if the battery capacity has been set correctly. 9.5.4. Synchronisation issues

What if the battery shuts off?

The battery shuts off due to undervoltage protection. Disconnect the battery from loads, and charge the battery with a current greater than 1A as soon as possible. The battery voltage exceeds the preset threshold during charging. 1. Disconnect the battery from the charging source. 2. Reduce charge voltage by 0.2V to 0.4V for 6 hours. 3.

Does a well-balanced battery disable a battery charger?

A well-balanced battery does not disable the charger, even when the batteries are fully charged. But when the BMS frequently disables the charger, this is an indication of cell imbalance. In case of moderate or large cell imbalance it is an expected behaviour that the BMS frequently disables the battery charger.
