If you are building a robot or portable device that needs 7.4V, you usually connect two 18650 batteries in series. However, charging them safely requires this board. It constantly monitors the voltage of both batteries individually. If one gets full (4.2V), it stops the charging to prevent explosion. If one gets empty (under 3V), it cuts the power to prevent permanent damage. It connects between your batteries and your load, acting as an automatic safety switch.
