BMS Protection Board 10S 20A Li-ion

The reliable BMS (Battery Management System) 10S 20A protection and balancing module is designed for assembling and safely operating 36 V battery packs based on Li-ion cells (18650, 21700 and others). Protection and balancing: Continuously monitors each of the 10 cells, preventing overcharging above 4.25 V, over-discharging below 2.75 V and short circuits, and equalizes cell voltages during charging. Symmetrical port (Common Port): Load and charger connections are made through unified power terminals (C- / B-), which greatly simplifies the switching circuit. Thermal control and cooling: Equipped with an aluminium heatsink for efficient heat dissipation and a remote NTC temperature sensor for automatic shutdown in case of overheating. Features Configuration: 10S (10 Li-ion cells in series, nominal 36 V / 37 V, full charge 42 V) Battery type: Li-ion / Li-Po (3.6 V / 3.7 V per cell) Maximum discharge current: 20 A (continuous) Maximum charge current: 10 A Port type: Common Port (B-, C-) Balancing function: Yes (With balance) Overcharge protection threshold: 4.25 V ±0.05 V Over-discharge protection threshold: 2.75 V ±0.1 V Protection: Against overcharge, over-discharge, short circuit, overcurrent, thermal protection (remote NTC sensor) Package contents: BMS 10S 20A board, balance lead with connectors
