2S 18650 Li-ion BMS Protection Board 20A Balanced Version 8.4V

This 2S 20A balanced BMS board is used for 2-cell 18650 lithium-ion battery packs with a full-charge voltage of 8.4V. It helps protect the battery pack and supports balanced charging for better cell safety. It is commonly used in small robot cars, portable speakers, rechargeable LED lights, mini UPS projects, and compact battery-powered devices. This is a good choice for projects that need more voltage than a single 18650 cell but do not require a 12V pack. Package includes the same components as the picture.
