Lithium Battery management system (BMS) or protection control module PCM for 2S3A lithium-ion 3.7v battery. It can be used with 18650 cells, 21700 cells and Lithium polymer cells of different size.
The 2S3A Li-ion BMS has following protections
- Over charge protection
- Over discharge protection,
- Over current protection,
- Short circuit.
Refer PCM 2S3A product specifications for more details.
The BMS 2S 3A 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) Additional Nickel Strip for ease of assembly with cells
