Lithium Battery management system (BMS) or protection control module (PCM) for 1S2A lithium-ion 3.7v battery. It can be used with 18650 cell, 21700 cell and Lithium polymer of different size.
The 1S2A Li-ion BMS has following protections
- Over charge protection
- Over discharge protection,
- Over current protection,
- Short circuit.
Refer PCM 1S2A product specifications for more details.
The BMS 1S 2A is must to protect the Lithium cells from extreme load conditions and ensure prolong life. The components used in the BMS are
1) Highly integrated IC,
2) low resistance MOS.
3) Nickel Strip for ease of assembly with cells
