The 26700-50E is a high‑capacity, safety‑focused lithium‑iron‑phosphate (LFP) cell. Its key advantages are an ultra‑large 5,000 mAh capacity and the inherent high safety of LFP chemistry, coupled with a stable 3.2 V nominal voltage and an internal resistance of just 15.0 mΩ. It supports 2.5 A charging and 10 A discharging, making it ideal for long‑duration applications such as portable energy storage systems and both large and small devices. The cell employs a high‑energy‑density LFP cathode material paired with a dedicated electrolyte to enhance both capacity and cycle life. Production utilizes a fully automated assembly line, with rigorous quality control ensuring 100% inspection and passing stringent cycle‑life and safety tests to guarantee product reliability. Its core competitive edge lies in balancing exceptional capacity with superior safety: after 1,000 cycles, capacity retention exceeds 80%, while its lightweight design—weighing no more than 99.0 g—makes it perfectly suited for 26700‑size equipment. Applications span energy storage, high‑power portable power supplies, and compact electric devices, with options for customized solutions and comprehensive technical support.
