10S20A BMS is the battery management system design for the 10 series battery pack of Lithium-ion cells which produce 36V. The Lithium batteries are prone to degrade if used without protection in non-favourable condition.
The 10S20A BMS, extensively used in Electric bilke (E bike) battery pack, protect batteries from Over discharge, Over charge, Short Circuit and over current. It is common port design with cell balancing feature.
10S20A Battery management system comes with moulded concealed body for the water and oxidation proof feature gives battery a long life.
There is snap in type balancing wire comes with the BMS facilitate easy and quick assembly.
This BMS has common port design help to reduce the number of connection for the ease of manufacturing.
One pack of BMS contains
1) Open BMS circuit board,
2) Wire with snap in connector for connection between cells and BMS.
