FAQs

1. Which batteries is this 14.6V 20A charger compatible with?

This charger is designed for 12V battery systems and supports multiple charging modes, including LiFePO4, NCM lithium-ion, and SLA/AGM lead-acid batteries. Please select the correct charging mode before use.

2. How long does it take to fully charge a LiFePO4 battery?

Charging time depends on the battery capacity and remaining charge. As a simple estimate, divide the battery capacity by 20A. For example, a 100Ah LiFePO4 battery usually takes about 5 hours from low charge to full, depending on battery status and charging conditions.

3. Does the charger stop automatically when the battery is full?

Yes. The charger uses smart CC/CV charging and automatically switches through the charging stages. Once the battery is fully charged, it stops active charging to help prevent overcharging.

4. What does 0V activation mean?

0V activation helps wake up a deeply discharged battery when its BMS has entered protection mode. This can help restore charging when the battery appears “dead” due to low-voltage protection.

5. Is the charger safe to use?

Yes. The charger includes multiple protection features, including overvoltage protection, overcurrent protection, reverse polarity protection, short-circuit protection, and overtemperature protection for safer everyday charging.
