State of Charge
The lifepo4 battery capacity could be roughly estimated by its voltage. As there are subtle differences in the voltage of each battery, the parameters below are for reference only.
The voltage needs to be tested at rest (with zero current) after 30 mins of disconnecting from charger & loads.
100%-13.5V // 99%-13.4V // 90%-13.3V // 70%-13.2V // 40%-13.1V // 30%-13.0V // 20% -12.9V // 10%-12.8V // 1%-10.8V (recommend low voltage disconnect voltage) // 0%-9.5V
Normally, the battery will be at 100% capacity when its rest voltage drops and remains at 13.4-13.6V.
Tips: Recommend to charge with Redodo LifePO4 Charger for longer use.
