LiFePO4 Battery Discharge and charge Curve
LiFePO4 batteries don''t need to be float charged because they don''t leak charge the way lead acid batteries do. If you can, disable float charging on your charge controller or battery charger. If you can''t, prevent the battery from entering float charge by setting the float voltage to that recommended in the battery manual — usually 13.6 volts ± 0.2 volts.
