What I’m imaging is having a switch like a dpdt (dual position, dual throw) switch to swap between in internal battery and an outlet which I’ll design in 3d to be mounted to the board for an external battery. I want the ability to completely disconnect the internal battery and plug in an external battery via xt60 connector.
Would a dpdt switch work for this? Could I wire this to the existing power switch/antispark? Can anyone recommend a switch which will handle the load?
