Description
Build your own 25.76V, 334Ah LiFePO4 battery using matched genuine EVE LF334 prismatic cells and a correctly selected JK BMS.
The 8S1P configuration provides approximately 8.60kWh nominal energy for mid-sized off-grid solar, cabin, workshop and backup-power projects.
Genuine EVE cells
Each EVE LF334 cell is rated at 3.22V, 334Ah and 1075.48Wh nominal energy. EVE specifies 4,000 cycles to 80% SOH at 25°C under EVE specified test conditions.
JK smart battery management
The included JK-PB2A16S-20P inverter BMS is configured for this pack and provides a 200A current rating, 2A active balancing, Bluetooth, CAN, RS485, temperature monitoring, configurable protection and pre-charge functionality.
CAN or RS485 hardware does not guarantee compatibility with every inverter. Confirm the supported protocol, firmware and cable pinout before ordering or commissioning.

DIY kit notice
This is an unassembled component kit, not a completed or certified drop-in battery. An enclosure, insulated cell restraint, main battery cables, lugs, fuse or circuit breaker, isolator, charger and inverter are not included unless separately stated.
Assembly should only be undertaken by a competent person familiar with high-current DC battery systems. Confirm polarity, use suitable cell restraint and insulation, install DC-rated over-current protection and configure the BMS before commissioning.
