The increased interest in IoT and electric automobiles around the world is driving an increase in the use of Lithium-Ion/Lithium-Polymer/NiCd/NiMH batteries as more devices and applications are using them, due to their high energy storage capacity to size ratio. This increased interest is, however, causing an increase in the number of batteries with “fake” ampere-hours ratings in the market. These fake ratings could lead to the failure of several projects, especially IoT projects in which developers factor in the Battery ratings in their On-time calculations. As such, to find a way of mitigating the failure-risks this problem poses, for today’s tutorial, we are going to build a battery capacity tester which can be used to get the correct energy storage capacity of any Lithium-Ion/Lithium-Polymer/NiCd/NiMH batteries (with voltage below <5v).
