The Roamer 100XTREME is the world's first lithium battery that can be fast-charged at -30°C without a heater. Where standard LiFePO4 batteries shut off charging in cold weather and heated batteries wait to warm up first, the XTREME simply charges — from -30°C, right now.
Military-grade cylindrical LiFePO4 cells with a specialised electrolyte prevent lithium plating in arctic conditions. Built for overland expeditions, winter van life, and any build where cold weather is a real problem rather than a theoretical one.
