After a whole month of working on this project, I was able to fit everything and solder the bms to the battery holder, and battery connector, and today it’s the first boot for the controller.
I still have a long way to go (because I used a pair of joycons that were mistreated by the previous owners, and they had stick drift) but the future looks bright.
It’s a little project for a friend of mine. I’m fitting an 18650 cell inside a pair of joycons with stick drift. I 3d printed the battery support (because I didn’t have a support for screwing in the battery holder) and the backshell too.
Why? 3/4 batteries inside of the joycons (I recieved) became spicy pillows. AND because I wanna upgrade the battery capacity from 500mah to 3000mah (for the lolz).
The plan is to install the battery with a bms, swap the old joystick with drift. And trying to figure out how to make the side button’s play tunable.
