The 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 various other applications.
Screw-connected prismatic battery cells can be easily mounted and connected with bus bars and screws, making them perfect for DIY projects.
Deep cycle capability with more than 2000 times life span - significantly longer life than lead acid batteries.
Foam-protected UN-certified cartons 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 additional testing is recommended. Basic knowledge of electronics and battery assembly is required. No refund or warranty for unprofessional operations. Some cells may have minor scratches from transportation, but this does not affect performance.

Note: Please choose your preferred shipping method. We can ship to other countries - contact us for details. Honesty is our priority. Be aware of unreliable cheap but fast shipping options.
Whether using Grade A, B, C, 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 due to the flat charge and discharge curve of this chemistry.
Proper initial balance ensures accurate capacity test results. If cells are unbalanced, it can trigger BMS protection and provide inaccurate capacity readings. Manual top balancing is recommended for large battery banks or cells with varying internal resistance.
While parallel connection allows natural balancing over time (weeks or months), manual top balancing provides immediate and reliable results, especially important for large loads and capacity testing.
