Compact power for your heated gear.
Keep your Lenz heated socks, gloves, vests, and jackets running strong with the Lenz Lithium Pack rcB 1400. These lightweight, rechargeable batteries connect easily via snap buttons and deliver reliable warmth for long, cold days outside.

Built with fast-charge, temperature protection, and a storage-mode function, these batteries are engineered for performance and longevity.
