U-Charge RT – ‘Plug ‘n’ Play’ Cobalt-Free Battery with Internal BMS The U-Charge® RT module is a ‘plug-and-play’ replacement module for lead acid applications typically requiring longer run time, zero maintenance, reduced charge time and high frequency operation readiness.
The U-Charge® RT series offers built-in automatic protection and an optional State of Charge indicator (Battery Discharge Indicator) and can be put in systems up to 48V. At less than half the weight of a comparatively sized lead-acid battery module, the U-Charge RT offers 70% more runtime and is increasingly being used for applications that are restricted by lead acid battery limitations and replacement down time.

U-Charge RT Peripherals ensure optimum performance, monitoring and control of battery modules.
The Battery Discharge Indicator provides a simple and elegant solution for display of basic information for the RT battery modules.
The BDI can be used with up to 2 U-Charge® RT 24V battery modules connected in series or parallel for fault and state of charge indication.
The Diagnostics ToolKit enables a battery module to communicate directly with a PC. It includes an RS485 to USB converter allowing data transfer.
Commonly used in starter batteries for internal combustion engine (ICE) vehicles Lead Acid is normally a low-cost secondary battery, composed of a lead-dioxide cathode, a sponge metallic lead anode and a sulphuric acid solution electrolyte. The heavy metal element makes lead acid batteries toxic and improper disposal can be hazardous to the environment.
U-Charge RT Lithium Iron Phosphate (LiFePO4) modules have considerably greater energy density making them particularly suitable for numerous applications. LiFePO4 is considered safer, less toxic, and more energy efficient with significantly longer cycle life.
