5S 18.5V 10A Li-Ion Battery Protection Board (BMS) for 18650 Batteries

The 5S 18.5V 10A Li-Ion Battery Protection Board (BMS) is designed to provide advanced protection and battery management for 5-cell lithium-ion battery packs built with 18650 cells. It safeguards the battery during charging and discharging by monitoring cell voltages and current levels, helping prevent overcharging, over-discharging, overcurrent, and short-circuit conditions. With low power consumption, low internal resistance, and support for continuous currents up to 10A, this BMS is suitable for battery-powered electronics, robotics, portable power systems, DIY battery packs, and energy storage applications.
