3.2V 20Ah Wide-Temperature Prismatic Battery Cell (-40°C to 55°C) | ATOMFAIR

COMMERCIAL GRADE PRODUCTION

Product Overview
The ATOMFAIR® 3.2V 20Ah wide-temperature prismatic cell is engineered to deliver reliable discharge at -40°C and stable charging at -10°C, addressing the most demanding extreme-environment applications. With a 3.2 V nominal voltage, 20.0 Ah rated capacity, and energy of 64 Wh, this platform demonstrates exceptional capacity retention and voltage stability across a broad temperature spectrum from -40°C to 55°C. Featuring 2C continuous charge and discharge capability at ambient temperatures, along with 0.2C charging at low temperatures, this cell ensures robust power delivery under cold conditions. The cell is designed with safety and longevity in mind, utilizing long-life lithium iron phosphate chemistry. This commercial-grade solution is ideal for electric motorcycles, portable energy storage, lead-acid replacement batteries, AGV systems, and humanoid robot applications where wide-temperature performance is essential.
