1S 3.7V 2A BMS for 18650 Battery

This 1S 3.7V 2A BMS Protection Board with nickel strip provides essential safety management for 18650 lithium-ion battery packs, guarding against overcharge, over-discharge, and short-circuit conditions. Its higher current rating makes it suited for applications drawing more power than the standard 1A version.

Featuring low current consumption and stable performance in a compact footprint, this module is a cost-effective, reliable choice for DIY electronics and custom battery pack projects. The included nickel strip simplifies assembly, ensuring a secure connection to your battery cells.

• Overcharge release voltage 4.23±0.05V – Precise overcharge protection
• Over-discharge voltage range 2.54±0.1V – Prevents deep discharge damage
• Over-current detection 2A~3A – Higher current protection threshold
• Nominal voltage 3.7V – Standard for single-cell lithium-ion packs
• Compact 20.8×3.5×2.4mm size – Fits easily into battery pack builds
• Includes nickel strip – Simplifies battery pack assembly
• Low current consumption – Efficient, stable long-term operation

Protect higher-current builds with this 1S 3.7V 2A BMS Protection Board – reliable safety for demanding 18650 applications.
