With the Hobbywing ESC it was actaully running fine but less static spec the 40C.
That weird gov like mode is either the esc hitting current limiting or low voltage cutoff. I would guess your esc is shutting down because the TP has lower internal resistance and is providing more current at higher voltage. The old batteries were the over stressed component in the system before, now since the batteries are up to it, the controller has to govern the current to save itself.
