4. Setup and Installation
Charging Methods
Your EASUN POWER LiFePO4 battery can be charged using two primary methods:
- Mains Power (AC Charger): Connect the battery to a compatible AC charger.
- Solar Panel (DC Power): Connect the battery to a solar panel system with an appropriate charge controller.
Compatible Charger Voltage
The charger voltage should 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
To prolong the battery's lifespan and slow down the reduction of its original capacity, a charging current below 0.5C is recommended. For example, a 100Ah battery should be charged with a current not exceeding 50A.
Connecting Multiple Batteries (Series/Parallel)
EASUN POWER LiFePO4 batteries feature a modular design, allowing for flexible configurations including up to 4 batteries in series and multiple in parallel. Identical batteries can be charged together after connection. The charging voltage for the battery bank should match the battery pack's charging parameters:
- For a 24V battery bank, the charging voltage should be 28.8V - 29.2V.
- For a 48V battery bank, the charging voltage should be 53.5V - 55V.
