The 2S 7.4V 5A Lithium Battery BMS Protection Module is a compact protection circuit board for two-cell (7.4V nominal, 8.4V full charge) lithium-ion battery packs. It safeguards 18650 and similar Li-ion cells from overcharge, over-discharge, overcurrent, and short-circuit conditions during everyday use.
Key features:
- 2S Cell Configuration: Designed specifically for two lithium-ion cells wired in series (7.4V nominal, 8.4V fully charged).
- 5A Continuous Current: Handles up to 5A of continuous discharge current for small power tools, lights, and battery packs.
- Overcharge and Over-Discharge Protection: Automatically disconnects the load when either cell’s voltage exceeds a safe limit.
- Short-Circuit and Overcurrent Protection: Cuts power instantly if a short circuit or excessive load current is detected.
- Compact Slim Profile: Narrow PCB fits easily inside battery packs, flashlights, and portable device enclosures.
