U-Charge® U1-12RT

U-Charge? U1-12RT

12V Battery Module

U-Charge? RT offers a simple `plug-and-play' replacement for typical lead-acid battery applications.

The Lithium Iron Magnesium Phosphate module offers 40Ah with a peak load capability of up to 80A incorporating built-in automatic protection.

Overview

Providing twice the run-time at approximately half the weight of a comparatively sized lead-acid battery, U-Charge? RT is a perfect choice when lower voltage and intrinsic safety are prerequisites.

Thousands of U-Charge? RT modules are currently in service within numerous industrial products. Excellent float and cycle life results in low operating costs, providing high investment returns for end user applications.
