BMS 7S 50A Protection Board Li-ion

The powerful BMS (Battery Management System) 7S 50A protection and balancing module is designed for assembling and safely operating 24 V battery packs based on Li-ion cells (18650, 21700, etc.). Protection and balancing: Continuously monitors each of the 7 cells, preventing overcharge above 4.25 V, overdischarge below 2.75 V and short circuit, and equalizes cell voltage during charging. Symmetrical port (Common Port): Load and charger connections are made through unified power terminals (C- / B-), simplifying the switching circuit in electric transport and energy storage systems. Thermal control: Equipped with a remote NTC temperature sensor to automatically cut off power in case of dangerous overheating of the battery pack. Specifications Configuration — 7S (7 Li-ion cells in series, nominal 25.2 V / 25.9 V, full charge 29.4 V) Battery type — Li-ion / Li-Po (3.6 V / 3.7 V per cell) Maximum discharge current — 50 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 7S 50A board, balancing wire harness with connector
