Project Description

PRODUCT INTRODUCTION

The BM21 Smart battery monitor is a high-precision meter that allows you to check the status of your battery via your Smartphone with the smart battery monitor App.

Through the use of a 75A/150A/500A current shunt, the battery monitor measures the discharge or recharge currents and calculates the Ampere-hours(Ah) going in and out of the battery.

High-precision voltage measurements are taken and displayed in real-time through the use of a field-installed sense wire. BM21 battery monitor is well-suited for lithium, LiFePO4, Lead-aid and nickel-metal hydride batteries.
