Lithium Battery management system (BMS) or protection control module PCM for  1S5A lithium-ion 3.7v battery. It can be used with 18650 cell, 21700 cell and Lithium polymer of different size.

The 1S5A Li-ion BMS has following protections

1. Over charge protection
2. Over discharge protection,
3. Over current protection,
4. Short circuit.

Refer PCM 1S5A product specifications for more details.

The BMS 1S 5A 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) Additoinal Nickel Strip for ease of assembly with cells
