280Ah LiFePO4 lithium battery is a favorite choice for DIY users in solar energy storage and off-grid backup systems. Ideal for caravan, camp caravan, golf cart, forklift, electrical bike, motorbike, and more.
Screw-connected prismatic battery cells can be easily mounted and connected with bus bars and screws, making them ideal for DIY projects.
Foams and UN carton packaging for safe transportation.
Please check all battery voltages and internal resistance to ensure they are balanced before DIY assembly. All batteries are tested before shipment, but you should verify them as well. You must have basic knowledge of electronics and battery assembly. No refund or warranty for unprofessional operations. Some cells may have small scratches due to handling or transportation, but this does not affect usage.

Please choose your preferred shipping method. We can ship to other countries - contact us for details. We prioritize honesty and reliability over cheap but unreliable shipping options.
Whether using grade A, B, or C cells, or used LiFePO4 cells, initial balancing is essential to bring them to the same state of charge. Voltage alone is unreliable for determining state of charge in this chemistry due to the flat charge and discharge curve.
Proper initial balance ensures accurate capacity test results. If cells are unbalanced, it can trigger BMS high or low voltage protection, leading to inaccurate capacity readings. For large battery banks or cells with varying internal resistance, manual top balancing is recommended regardless of initial voltage readings.
