Battery tester - all but big LiPO RC types
This is the charger https://amz.run/7td0 I decided to get. It will charge, discharge, charge for storage and calculate capacity for all sizes other than the big RC LiPO packs. I have personally charged AAA, AA, 18650, and 26650. I am enclosing a screen shot of the batteries it does, the list is too long to type in.
Battery chemistries are in 3rd pic.
I prefer to use the phone app, it's simple. The instructions for the charger are too complex for me so that is why I use the phone app. I have not tried the PC app yet on either Windows or Mac.
