I charge at two locations. 220V @ 24 amps at one and 120V @ 13amps for the other (btw, 4hrs @ 120vac per day meets my daily charging needs). I've noticed that during charging, the coolant circulation pump is running continuously. Concerned that charging at 110vac will put undo wear on the circulation pump and it's fluid seals. I assume the pump is a brushless motor and not a short service brushed motor. So does anyone on this forum know the robustness of the coolant pump and it's seals?
