BU Long-time Backup Power Series

Product features

Main application areas

1. With rich communication interfaces e.g. multiple RS485, CAN, Ethernet, dry contact input and output interfaces, supporting most of PCS and UPS communication in the market. 

2. Adopt internal cell equalization function, the maximum equalization current can reach 300mA.

3. Support high precision collection of battery voltage and temperature: ±3mv, ±1℃;

4. Achieve the parallel usage of lithium battery system easily with automatic circulating current control, and automatic parallel or offline control 

5. With complete self-test and operation status detection function. Easy to know system operation information with HMI display. When used in parallel, only one HMI display is required for each system.

6. Adopt long-time power backup design to decrease the costs for customers.


Leoch offers a safe LiFePO4 battery solution for UPS and energy storage systems with good compatibility and safe long cycle life. The battery system consists of a three-level architecture, with a module-level management system BMU integrated in the battery pack, which is responsible for collecting the information of single cell voltage, module temperature, battery equalization, and communication with upper management system. The adopted CBMS cabinet-level management system is responsible for battery current detection, data collection and analysis, alarm and protection control, and communication with the upper and lower levels. The general control GBMS is responsible for data analysis, lower level system communication, and UPS communication.
