It is best to use a dedicated LiFePO4 battery charger to charge LiFePO4 battery. High quality LiFePO4 chargers ensure high performance and long battery life.
Is it possible to use a lead-acid battery charger?
You can use lead-acid to charge LiFePO4 battery. However, there are two issues to be aware of here:
1, Extended charging time
Lead-acid battery chargers will reduce the current output as the battery voltage increases. This will result in longer charging times.
2, Cannot fully charge the battery
When the battery voltage reaches 13.1V, the lead-acid battery charger has almost no current output. So the lead-acid charger cannot charge the LiFePO4 battery to 14.6 V(The full charge voltage of LiFePO4 battery is 14.6 V ).
Will the use of other types of chargers damage LiFePO4 batteries?
If you have a BMS with charge protection in your battery pack, it will protect the battery from damage.
When should I charge?
You can charge your LiFePO4 batteries after each use or when they have been discharged up to 80% DOD (20% SOC).
What is the temperature range for charging LiFePO4 batteries?
LiFePO4 batteries can be safely charged between 0°C to 45°C (-32°F to 113°F). Do not charge below 0°C (-32°F) without heating, as this can damage the battery.
Can I fully discharge a LiFePO4 battery?
Although LiFePO4 batteries can be discharged to 100% of their capacity. To optimize the performance of your LiFePO4 battery, achieve a higher cycle life, and avoid the BMS disconnecting the battery, we recommend limiting the discharge to 80% capacity.
If the BMS disconnects the battery due to low voltage, at 100% depth of discharge, remove the load and recharge with a LiFePO4 charger to reactivate the BMS.
