Level up controller no power

[AlmostRetired]

I destroyed my batteries and didn’t have enough power to even light the control panel box. Called Level Up after I had fixed power issue and they walked me through a reset. Had to disconnect a couple wires (easily accessed) and that reset. The panel still wouldn’t light up but they provided the sequence of which buttons to push without visual guidance and I got it to function. Once the 12V system was charged everything worked fine and I had no further issues.
