Harveypower's BMS system monitors and regulates wall mount battery charge and discharge status. The monitored battery characteristics include the detection of battery type, voltage, temperature, capacity, state of charge, power consumption, remaining operating time, charge cycles, and more.
It can process and monitor up to 16 wall battery pack at the same time, provide a battery balancing function, manage different batteries with the same charge and discharge requirements, and ensure the optimal utilization of the remaining energy in the battery.

Build an LED display outside the product group to visualize the overall data and status of the battery pack. You can also DIY the operation functions of the display according to your needs.
Not only can we know whether the remaining available capacity of the battery can meet our demand for the total temporary power consumption, but also know when each single battery and battery pack needs to be replaced and repaired.
