7S20Amp 24V Lithium Ion Battery Management System (BMS)
₹474.58
Battery management system (BMS) 7S20A for lithium-ion 24v battery packs, it can be used with 18650 Li ion cells and Lithium polymer (Lipo) of different size.
The 7S20A Li ion BMS has protection for the battery over charge and over discharge, over current, short circuit, over-temperature. Refer product specification for more details.
The BMS 7S 20A comes with equalization function which facilitate to keep the cells at same level and ensure prolong life. The components used in the BMS is
1) Highly integrated IC,
2) low resistance MOS, and
3) high current equalizer.
One pack of BMS contains
1) Open BMS circuit board,
2) Wire with snap in connector for connection between cells and BMS.
