This is the second post i’m seeing that says to solder the power button from the back. but i wish there are some pictures actually showing the back!
Question.
is the switch in use like a push button switch? just need to trigger open->closed->open for a while? what if i were to use a normal slide switch? would that work?
As Chris_McIntosh already said, there are only two holes visible on the back of the battery board! (See “J6” in the picture.) You can thread the wires through there and solder them.
I originally planned on using a push button switch until I realize that the switch does the opposite (I have to hold it to turn it on lol) so I decided to use a toggle switch and added a 2 point SJT connection for easier removal (with annoying wiring).
