Arduino Nano Battery Tester: Soldering Timelapse

This is a continuation of the previous project video “How To Build A Battery Tester” where we take an Arduino Nano and a few other electronic parts to build a AA battery tester that will give us fairly accurate “real world” readings on NiMH batteries. This little device will come in handy for the next project on the list, so be sure to subscribe for more how-tos!

Do you have some rechargeable batteries lying around that need a capacity check? Let’s put together an Arduino-powered Battery Tester so we can verify the listed capacity of these cells!

The PSIVEN Helping Hands are the best prosumer level soldering helping hands that I have been able to find!
