The battery is a LiFeYPO4 type but during the video I will also include Li-Ion and LiPo batteries and show you exactly how you can test their capacity and internal resistance in order to determine if they are still good to go. These tests are of course also suitable for all other battery types which means you will be the "master" tester for all of them after finishing this video ;-) Let's get started!
