Protection and balancing board for lithium batteries BMS 3S 40A with balancer function (model HW-288)

The three-channel protection and balancing board (BMS) model HW-288 is designed for safe operation and longer service life of 3S battery packs (based on three series-connected lithium-ion or lithium-polymer cells with a nominal voltage of 11.1V and a maximum charged battery voltage of 12.6V). The module supports a high working current of up to 40A and features a balancing circuit that ensures even charging of each individual cell. The built-in multi-level protection effectively prevents emergencies caused by short circuits, excessive discharge or overcharging. Features: Product type: protection and balancing board for lithium-ion batteries (BMS Protection Board) Specifications: 3S configuration (for 3 series-connected cells), maximum working current up to 40A, built-in cell balancing function, full charge voltage 12.6V, model HW-288 Purpose: protects battery packs from overcharging, over-discharging, overcurrent and short circuits, and equalizes the voltage across the cells
