Deep cycle capability with more than 2000 cycles lifespan. Longer operational life compared to lead acid batteries.

Protected with foam and UN-certified cartons for safe transportation.

Suitable for golf carts, RVs, solar storage systems, E-motorcycles, home energy storage systems, powerwalls, and various other applications.

Check all battery voltages and internal resistance to ensure they are balanced before DIY assembly. While all batteries are tested before shipment, verification upon receipt is recommended.

Basic knowledge of electronics and battery assembly is required. No refund or warranty is provided for unprofessional operations. Minor surface scratches may occur during transportation but do not affect performance.

We ship to other countries - contact us for details. We prioritize honesty and reliability over cheap but unreliable shipping methods.

Regardless of cell grade (A, B, C) or condition (new/used), initial balancing is essential to bring all cells to the same state of charge. Voltage alone is an unreliable indicator for LiFePO4 chemistry due to the flat charge/discharge curve.

Proper initial balancing ensures accurate capacity test results and prevents premature triggering of BMS protection circuits. If balancing issues persist, manual top balancing is recommended rather than relying solely on active balancers.

While parallel connection allows natural balancing over time (weeks to months), manual top balancing provides immediate and reliable results, especially important for large battery banks or cells with varying internal resistance.
