The U-Charge XP lithium ion battery series is a family of 12V, 18V, 24V and 36V lithium battery modules. The U-Charge XP modules are traditionally arranged in a multi-series/parallel configuration and not as a single battery replacement. Our Battery Management System (BMS) monitors and communicates with the batteries and is required with all U-Charge batteries.
