The protection thresholds below are supplier information requiring confirmation for the actual revision. The source lists both 2.50 V and 2.55 V as discharge thresholds. Do not use these conflicting figures as design limits.
B 6S 12A BMS 18650 Lithium-Ion Battery Protection Board
Meet the 6S 12A BMS 18650 Lithium-Ion Battery Protection Board – a protection board for six 3.7 V lithium-ion cells in series. It monitors the pack and disconnects under certain fault conditions. Suitable cells, a fuse, correct wiring and a separate compatible charger are still required.
The board is intended for battery protection, not charge regulation. Check current limits and cooling for the actual hardware revision. The conflicting current limits in the original listing must be resolved before use.
Key functions
- Protection for six Li-ion cells: This board is specifically designed for battery packs with six Li-ion cells in series, monitoring the connected battery pack.
- Precision integrated circuit: Monitors fault conditions; does not replace a CC/CV charger.
- Overcharge and overdischarge protection: Keeps batteries within their intended range with automatic detection and protection against overcharging and overdischarging.
- Short-circuit protection: Helps protect the circuit against short circuits.
- Check before use: Individual load and ageing tests are not documented. Verify board operation in the finished system.
