Features
-
01
High discharge Capacity
Under low-temperature conditions, it can provide the required current to the load while maintaining a small capacity for the li-ion battery. This significantly reduces the overall weight of the low-voltage power supply and lowers the cost.
-
02
Mature BMS platform
High-precision sampling, hardware coulometer, OCV and EKF calibration ensure SOC accuracy.
MOSFET instead of traditional fuse, millisecond fault response capability.
Multiple low-current charging circuits of 0.5A, 1A, 2A, and 4A, adapting to different application scenarios such as low temperature or severe undervoltage to extend battery life. -
03
Customizable
We can customize the structure, cell, BMS and other system solutions according to the actual needs of customers.
