BMS Protection Board 7S 10A Li-ion

Compact BMS (Battery Management System) 7S 10A protection and balancing module is designed for assembling and safely operating low-power 24V battery packs based on Li-ion cells (18650, 21700, etc.). Protection and balancing: Continuously monitors each of the 7 cells, preventing overcharging above 4.25V, over-discharging below 2.75V and short circuits, and equalizes cell voltages during charging. Symmetrical port (Common Port): Load and charger are connected through common power terminals (C- / B-), which greatly simplifies the switching circuit. Compactness and reliability: Suitable for low-power electric transport, 24V backup power supplies, portable speakers and LED lighting. Features 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 — 10 A (continuous) Maximum charge current — 5 A Port type — Common port (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 (external NTC sensor) Package contents — BMS 7S 10A board, balance lead with connector
