we will test all the lifepo4 batteries' capacity, voltage, and Internal Resistance. The capacity must be above the rated capacity, the voltage deviation must be less than 0.5V. We balance all raw batteries to ensure that the internal resistance, voltage, and capacity are completely matched and balanced before packing.

Using laminated production technology, LiFePO4 Battery has higher capacity and better performance in charging and discharging, and life cycle, with a thinner body, lighter weight, more flexible size, and shape, which can adapt to a variety of applications, has better stability and tolerance in high-temperature discharging.

We provide original raw battery cells with intact QR Codes and Grade A+ performance. Our supply comes directly from CATL, EVE factory. We also own a warehouse in Germany, shipping by FedEx, with a complete supply chain, making the lead time within 1 week
