18650 Lithium Battery Capacity Tester using Arduino
With the advent of technology, our electronic gadgets and appliances are becoming smaller and smaller with more functional and complex applications. With this increase in complexity, the power requirement of the circuit has also increased and in our quest to make the device as small and as portable as possible, we need a battery which can provide high current for a long period of time and at the same time, weigh much less so that the device should remain portable.
