3S 10A BMS Protection and Balancing Board for Lithium Batteries (Triangular)

The 3S BMS protection and management board is designed for the safe operation of a pack of three lithium-ion (Li-ion) cells connected in series, with a nominal total voltage of 11.1 V. The module features a convenient triangular form factor, allowing it to fit compactly inside the battery pack. An integrated control circuit and power MOSFETs protect the battery from critical overcharging, over-discharging, short circuits, and load current exceeding 10A. The board has clearly marked contact pads to simplify wire connections.

Features:
Product type: lithium-ion battery protection board (BMS, Battery Management System)
Specifications: 3S configuration (nominal voltage 11.1 V, maximum up to 12.6 V), operating current up to 10A, compact triangular shape
Connections: pads for connecting the cells (B-, B1, B2, B+) and the load/charge power terminals (P-, P+)
Purpose: comprehensive protection of a battery pack made of three Li-ion cells in series against overcharging, deep over-discharging, short circuits, and overcurrent
