U-Charge® Battery Management Systems (BMS) are designed for use with U-Charge® XP battery modules.

The BMS provides numerous system integration options facilitating temperature, voltage, current and state-of-charge monitoring. One single BMS is capable of managing up to 48 U-Charge® XP battery modules in 12V,18V or 36V configurations.

U-Charge® Battery Modules offer twice the run-time at nearly half the weight of similar sized lead-acid batteries, offering outstanding intrinsic safety, excellent float and cycle life resulting in low cost of ownership. Thousands of U-Charge systems have been deployed since 2006, across numerous motive and energy storage applications.
