The 1S 5A 18650 Lithium Battery Protection Board is a compact BMS (Battery Management System) designed to monitor and safeguard a single 3.7V 18650 lithium-ion rechargeable cell. With integrated overcharge, over-discharge, and short circuit protection, this board ensures long battery life and stable performance in a wide range of battery-powered applications.
This BMS comes with a pre-soldered nickel strip for immediate integration into DIY battery packs. It automatically cuts off power when voltage thresholds are exceeded or dropped below safe limits, and can auto-recover or be reactivated by applying input voltage. Engineered for long-term operation, it supports up to 30,000 hours of performance in harsh conditions.
