Hi, I am looking into building a 18650 charger/tester. I am thinking of something like a 16 cell tester or something. From what I have researched I have seen most people using an arduino as the controller. The problem is the I have never written code for an arduino and so the code would probably have to be already written. I do have some experience with hardware though, but I would be interested in something that is designed already and that I could just build off a schematic.
So basically, a tester that has the code and software ready to download and the schematic designed for the hardware.
Any suggestions?

Honestly, just get some off the shelf Lithium C/D/C chargers like the Liitokala Li-500 or the Opus.
I got 7 chargers, totalling 28 bays for just 100€ and dont have to bother with the whole pcb design, calibrating & writing software stuff.

And this is why I love this forum because I don't have to reinvent the wheel and can iterate on others work instead :) Now I just need to find a forum community like this for PCB design/esp32 coding/smarthome projects.

Yeah I like GitHub but does it have a social platform just for connecting in a less technical project specific way?
