3S Battery Protection and Balancing BMS Board for Li-ion Batteries (model XR-AL-3S5216-V70)

Compact protection and control board (BMS) model XR-AL-3S5216-V70 is designed for safe operation of battery packs made of three series-connected Li-ion cells (3S with nominal voltage 11.1V and maximum 12.6V). The module effectively prevents emergency operating modes, protecting cells from overcharging, over-discharging, current overloads and short circuits. The fiberglass board features clearly marked contact pads for cell balancing and connection (B0, B1+, B2+, B3+), load power wires (P+, P-), and a mounting spot for a thermistor (T). Features: Product type: protection and battery management board / BMS 3S (Battery Management System) Specifications: model XR-AL-3S5216-V70, 3S configuration (for assembly of three Li-ion batteries 11.1V / 12.6V), connection contacts B0, B1+, B2+, B3+, power terminals P+ and P-, thermistor contact T Purpose: comprehensive protection of battery packs against overcharging, deep discharge, overcurrent and short circuit
