How to make your own 18650 (or any lithium/li-ion) cell/battery capacity checker/tester. In this series, I design a really simple circuit and talk you through it. I walk you through every single step in both the electronics and code. In this video, I improve the ADC accuracy by using the internal voltage reference.
