BMS Protection Board 10S 30A Li-ion

The reliable BMS (Battery Management System) 10S 30A protection and balancing module is designed for assembling and safely operating 36 V battery packs based on Li-ion cells (18650, 21700, etc.). Protection and balancing: Continuously monitors each of the 10 cells, preventing overcharge above 4.25 V, overdischarge below 2.75 V and short circuits, and equalizes cell voltages during charging. Symmetrical port (Common Port): The load and charger are connected through common power terminals (C- / B-), which greatly simplifies the switching circuit. Thermal control and cooling: Equipped with an aluminum heatsink for efficient heat dissipation and a remote NTC temperature sensor for automatic shutdown on 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 — 30 A (continuous) Maximum charge current — 15 A Port type — Common port (Common Port: B-, C-) Balancing function — Yes (With balance) Overcharge protection threshold — 4.25 V ±0.05 V Overdischarge protection threshold — 2.75 V ±0.1 V Protection — Against overcharge, overdischarge, short circuit, overcurrent, thermal protection (remote NTC sensor) Package contents — BMS 10S 30A board, balance lead with connectors
