Product Highlights

Intelligent Control

Intelligent Control

Support 4 outputs, each output has independent electronic switch, can quickly respond to circuit fault such as short circuits or overcurrent, isolate safety loads from regular loads.

Extended Service Life

Extended Service Life

Ultra long lifespan design, Cycle Life ≥ 8000 cycles, which is about twice as much as mainstream products. It ensures customer's product life, reduces annual usage costs, significant total life cycle cost advantage compared to traditional lead-acid batteries.

Mature BMS Platform

Mature BMS Platform

High-precision sampling, hardware coulometer, OCV and EKF calibration ensure SOC accuracy. MOSFET instead of traditional fuse, millisecond fault response capability.
