1S 5A Lithium Battery Protection Board BMS for 18650 Cells

This 1S 5A BMS module offers overcharge, over-discharge, and short-circuit protection for single-cell lithium batteries. Designed for 18650 batteries, it ensures safe and efficient operation for DIY electronics projects.

• 1S 5A BMS protection module
• Small size designed for a four-cell battery pack.
• Over-charge/Over-discharge Protection.
• Pre-soldered Nickel Strip ready to mount on battery.

BMS (Battery Management System) – a battery management system that is designed to monitor the status of batteries, control the process of charging/discharging the battery, etc.

This BMS charge-discharge controller module comes with pre-soldered nickel strip ready to use for a single 18650 rechargeable cell. The module has protection against short circuit, overcharge and over-discharge. One of the functions of the charge controller is to turn off the power supply for the batteries when the maximum capacity of at least one battery is reached. This BMS controller is designed for more than 30,000 hours of operation. The maximum allowable current is 5A.

If the maximum permissible value of the supply voltage is exceeded, the charge controller activates the “protection” mode. In order to restore the module, it is necessary to re-apply voltage to the input of the BMS board or wait a while until the charge controller automatically disables protection.
