4. Operating Instructions
4.1 Charging the Battery
Your Easun Power LiFePO4 battery can be charged using two primary methods:
- Mains Power Charging: Use a compatible battery charger connected to a standard electrical outlet.
- Solar Panel Charging: Connect to a solar panel system for DC power charging.
Description: Diagram illustrating two charging methods: 1) Mains charging via a wall socket and a battery charger, and 2) Charging from solar panels (DC power).
Compatible Charger Voltage:
The charger voltage must match the battery's nominal charging voltage range. For a 12V battery, the charging voltage should be between 14.4V and 14.6V. When using specific chargers, ensure the charging mode is set to 'LiFePO4 battery' or 'Lithium battery'.
Charging Current Limitation:
For a 100Ah battery with a 100A BMS, the battery can handle a charging current between 1A and 100A. To prolong the battery's original capacity and extend its lifespan, a charging current below 0.5C (e.g., 50A for a 100Ah battery) is recommended.
Charging Connected Batteries:
Identical batteries connected in series or parallel can be charged together. The charging voltage must be appropriate for the combined battery bank:
- 24V Battery Bank: Charging voltage 28.8V - 29.2V.
- 48V Battery Bank: Charging voltage 53.5V - 55V.
Recommended AC Charger:
Any lithium charger with a 14.4V-14.6V charging voltage is suitable. The crucial point is to ensure the charging current does not exceed 50A (0.5C).
