Working on the stand alone battery power for the bottle heater. Made some progress on that today...
The bottle has an adjustable pressure switch that will turn off the heater when it reaches 1000 psi. Uses DeWalt 20v cordless batteries for power to maintain temp yet keep the drain off the car battery in the staging lanes.
That is such a great idea using the dewalt battery. Do you have a photo of the panel mounted in the trunk??
