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.
First computer 1959. Retired from my own computer company 2004.
Hardware - Expert in 1401, and 360, fairly knowledge in PC plus numerous MPU's and MCU's
Major Languages - Machine language, 360 Macro Assembler, Intel Assembler, PL/I and PL1, Pascal, Basic, C plus numerous job control and scripting languages.
Sure you can learn to be a programmer, it will take the same amount of time for me to learn to be a Doctor.
