BMS Protection Board 13S 15A Li-ion

Compact BMS (Battery Management System) protection and balancing module 13S 15A is designed for assembling and safely operating 48V battery packs based on Li-ion cells (18650, 21700 and others). Protection and balancing: Continuously monitors each of the 13 cells, preventing overcharge above 4.25V, overdischarge below 2.75V and short circuit, and equalizes cell voltages during charging. Common Port: Connection of the load and charger is made through shared power terminals (C- / B-), which greatly simplifies the switching circuit. Compact and reliable: Suitable for low-power electric transport (e-bikes, electric scooters), power tools and 48V backup power sources. Features Configuration — 13S (13 Li-ion cells in series, nominal 48 V / 48.1 V, full charge 54.6 V) Battery type — Li-ion / Li-Po (3.6 V / 3.7 V per cell) Maximum discharge current — 15 A (continuous) Maximum charge current — 8 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 (external NTC sensor) Package contents — BMS board 13S 15A, balance lead with connector
