Miniature BMS 1S 3A 3.7V Protection Board with Pre-Soldered Nickel Strips

The miniature BMS 1S protection board is designed for safe operation of single lithium-ion (Li-ion) or lithium-polymer (Li-Po) batteries with a nominal voltage of 3.7V (and a full-charge voltage of 4.2V). The device continuously monitors voltage parameters, preventing critical overcharging, deep over-discharge and short circuits. The pre-soldered nickel strips significantly simplify integrating the board into the battery pack using a spot welder. Features: Product type: miniature lithium-ion battery protection board / 1S BMS (Battery Protection Board) Specifications: 1S configuration (for single cells with a nominal voltage of 3.7V / maximum 4.2V), operating current up to 3A, compact elongated shape, factory nickel strips for quick installation Purpose: protection of single lithium-ion (Li-ion) and lithium-polymer (Li-Po) batteries from overcharging, over-discharging and short circuits
