If you have 12.75V at the battery and have T1 power, the charger is most likely dead in the controller and you will need a new control panel. I think you mean 2A charger, but even still, that battery should be higher voltage than that with a charger hooked to it... Most chargers run the battery up around 13.5VDC when fully charged.
I have one more of those panels left in stock right now. https://shop.gentekpower.com/products/g ... trol-panel

Did you make any changes since last we spoke? Still sounds like you have a bad controller to me...

If you have power into the controller from T1 and also the battery and no life out of the controller, there's not much else to test unfortunately
You could try to power cycle it by removing a battery cable and the T1 harness and then reconnecting everything and see if it comes back to life.
