Battery management system (BMS) 13S40A for lithium-ion 48v battery packs. It can be used with 18650 cells and Lithium polymer of different size.
The 13S40A 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 13S 40A 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.
