The discharge and charge processes of LiFePO4 battery packs are controlled by a LiFePO4 BMS. So, if something goes wrong during these procedures, the BMS protection kicks in and either modifies the charging settings or completely shuts down the power flowing to and from the battery pack.
I have a used 24v lifepo4 pack, and I can charge it up to any max voltage I want but it will quickly settle back to 26.5v (equivalent to 13.25v for you). This is not necessarily bad - while discharging, the pack stays in the 26.0 to 26.4 range for a long time (showing the famous flat discharge curve for lifepo4).
An MPPT charge controller is more suitable for charging a LiFePO4 battery pack with solar power, as it is more efficient. Although a PWM charge controller is cheaper, it is less efficient compared to an MPPT charge controller.
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.
A LiFePO4 battery cell fully charged to 100% will hold a voltage of around 13.3-13.4v. For comparison, a lead-acid battery cell at the same state of charge will have a voltage of about 12.6-12.7v.
The number of cells (and their chemistry) in a battery pack will determine its nominal voltage. Individual LiFePO4 cells have a nominal voltage of 3.2V. This way, connecting four LiFePO4 cells in series results in a battery pack with a 12.8V nominal voltage. Amperage is a measure of electrical current flow.
If the voltage is lower than 10V (for a 12V lithium battery) or 20V (for a 24V lithium battery), your battery is in under-voltage protection mode. Remove all connected wires afterwards, use an appropriate lithium battery …
