Product Description
This 3S 12.6V 6A BMS lithium battery protection board is a professional battery management and balancing module specially designed for 3-series 18650 lithium-ion battery packs. It integrates multi-dimensional safety protection and cell equalization functions, effectively solving common problems such as battery overcharging, overdischarging, overcurrent, short circuit and inconsistent cell voltage, greatly extending the overall service life and working stability of the battery pack.
Built with high-quality control IC and premium MOS tubes, this protection board supports 6A continuous discharge current, with stable output and strong load capacity. The built-in cell equalizer can automatically balance the voltage of each single battery during charging, avoiding partial overcharge and discharge caused by voltage difference between cells, and improving the charging efficiency and cycle life of the battery pack. Equipped with intelligent temperature protection and automatic recovery design, it can cut off the power supply in time under abnormal conditions and resume normal work after troubleshooting, which is safe and worry-free.
Compact in size, easy to install and wire, this BMS board is perfectly compatible with 3S 11.1V/12.6V 18650 battery packs. It is widely applicable for electric drills, electric screwdrivers, power banks, small household power supplies, DIY energy storage equipment and other low-power electrical devices, serving as an essential safety accessory for lithium battery assembly and modification.
