Description
Introduction:
EK-NCM-07S-30A-0CB-1-ST1 is an 7cells battery pack designed in series for battery protection solution by EBAK,
Which use for the application on LiFePO4 base battery packs. this series include 7S 24V 15A/20A/30A/40A/50A/60A/80A/100A/120A/150A/200A/250A bms which is used for 7 series 24V battery pack.
* Monitors temperature, cell voltage, pack voltage, current, state-of-charge, work status
* Over charge protection, over discharge protection, over current protection, short-circuit protection, temperature protection etc.
* Automatic cell-to-cell balance control
* Accurately calculate the capacity and life of the battery
* BMS manufactured by high quality Mos and IC imported
* Use top quality (A-level) protective integrated circuit IC, from the solution of Seiko of Japan.
* Extreme low power consumption. The consumption of the whole device is less than 50uA.
