CBAK 32140 3.2V 15Ah Battery Cell

The CBAK 32140 3.2V 15Ah Battery Cell is a high-performance cylindrical LiFePO4 power solution, engineered for safety, reliability, and long service life in electric bicycles, light electric vehicles, and portable energy storage systems. As a premium 32140 LFP battery, it leverages a robust LFP cathode and graphite anode chemistry to deliver inherent thermal stability and a low risk of thermal runaway, making it the ideal 3.2V 15Ah LiFePO4 cell for applications where safety is non-negotiable. With a nominal voltage of 3.2V and a typical capacity of 15Ah, this 15000mAh LiFePO4 battery provides 48Wh of energy, enabling the design of high-capacity e-bike battery packs that meet modern power and range demands for commuting and leisure use.

Built for durability, the CBAK 32140FS battery delivers up to 2000 cycles with 80% capacity retention, significantly reducing long-term ownership costs and replacement frequency for fleet operators and end-users. Its low internal impedance (≤3mΩ) and 2C (30A) maximum continuous discharge rate ensure efficient power delivery for high-demand operations, such as rapid acceleration in electric bicycle battery systems or peak load support in portable power stations. The cell’s wide operating temperature range (discharge: -20°C to 60°C; charge: 0°C to 45°C) ensures reliable performance in diverse climates, while its compact, lightweight design (33.2±0.2 x 140.0±0.3mm, 300±5g) simplifies integration into custom battery pack designs for OEMs and system integrators. Whether used as a core component in 32140 cylindrical LiFePO4 battery packs or as a building block for scalable energy storage solutions, the CBAK 32140 3.2V 15Ah Battery Cell combines the proven benefits of LFP technology with the manufacturing quality of CBAK, solidifying its position as a trusted choice for high-performance, long-lasting power systems.
