On my 7k axles, they draw 6 amps per axle, So stick a 30 amp fuse in it and send it.

Do you know if they see a full 12v or does the brake switch limit voltage?
My brake controller shows it ramping up proportional to the force required. For emergency braking, it is directly connected to the battery, the full 12 (13.2) volts.
My trailer has living quarters and a generator, and i wanted to hook to the large battery, so I ask the inspector about the battery, he said "as long as the battery is independent of the towing vehicle" and able to fully apply the brakes if disconnected from the tow vehicle.
