BMS - Battery Management System

BMS battery management system
BMS - battery management system is device that extends battery life by precise monitoring battery status and high‑safety communication to prevent overcharge and over discharge. Advanced algorithm precise calibrates status of lithium‑ion batteries based on data collect from performance tests with a deviation of less than 5%.
