Key Features of Lead Acid BMS Board

bms with High-accuracy SOC/SOH

High-accuracy SOC/SOH

An upgraded lead acid battery management system delivers precise SOC and SOH estimations, narrowing SOC errors from ±20% to ±5%. It achieves this through online parameter tracking and self-correction during charging, ensuring SOC errors stay below 5%, thereby enhancing battery utilization and operational safety.

bms with Efficient Low-Power Design

Efficient Low-Power Design

The battery monitoring module draws power from the battery monitor itself. When it comes to lead acid batteries, our BMS employs smart power management and an upgraded power supply circuit. This setup allows the lead acid battery monitoring system to operate with an ultra-low current of just 3mA, ensuring it has minimal impact on the batteries it's monitoring.
