Felicity Solar 2.56kWh 24V LiFePO4 Lithium Battery

Felicity Solar 2.56kWh 24V LiFePO4 Lithium Battery

The Felicity Solar FLA24100WG2 is a compact low-voltage lithium iron phosphate battery designed for compatible 24V solar inverter, off-grid and backup-power systems. It provides 2.56kWh of nominal energy capacity in a flexible enclosure that can be installed on a wall or placed on the floor.

A 100A continuous charge and discharge rating gives the battery the current capability required by suitably matched inverter systems, while its 200A peak rating supports short-duration demand. Built-in monitoring, smart battery management and expansion support make it suitable for both starter systems and installations that may require additional storage later.

2.56kWh LiFePO4 Energy Storage

• 2.56kWh nominal energy capacity
• 25.6V nominal battery voltage
• 22.4V to 28.8V operating-voltage range
• Lithium iron phosphate battery chemistry
• At least 95% supported depth of discharge
• At least 6,000 cycles at 25°C and 80% depth of discharge

LiFePO4 chemistry provides stable performance and a long service life when the battery is correctly installed, configured and operated within the manufacturer’s limits.

Strong Charge and Discharge Performance

• 100A maximum continuous charge current
• 100A maximum continuous discharge current
• 200A peak charge and discharge current for 15 seconds
• 2,500W maximum charge and discharge power

The permitted continuous current can be affected by battery temperature and state of charge. The connected inverter, cables, protection equipment and operating settings must remain within the battery specifications.

Expandable Battery Capacity

Up to 15 FLA24100WG2 batteries can be connected in parallel for a combined nominal capacity of 38.4kWh. Parallel installations must use identical compatible battery models and follow the manufacturer’s connection, protection and commissioning requirements.

Smart BMS and Communication

• Built-in smart battery-management system
• Built-in fuse protection
• RS485 and CAN communication
• Built-in Wi-Fi and Bluetooth for supported real-time monitoring
• LCD and LED battery-status display

Communication compatibility must be confirmed for the selected inverter model before installation. Correct communication settings allow the inverter and battery-management system to coordinate charging and discharging safely.

Flexible Wall or Floor Mounting

The battery supports wall-mounted and floor-mounted installation, allowing the installer to select an appropriate arrangement for the available space. The IP21 enclosure is intended for a protected indoor installation area that remains dry and suitably ventilated.
