I'd planned for the Milwaukee battery to be in the cab.
I like the "switch" idea.
Thank you.

You're welcome. It seems to be easier than unhooking a battery every time.I like the "switch" idea.
Thank you.
I dont know why, but this thread reminds me of a guy I know, that since the heater core was plugged in his truck, used a small diesel fueled torpedo heater on the seat to keep warm. Generator in the bed.
The only problem with that scenario is that, without the belts, there's nothing to turn over the water pump. Hopefully you'll never find yourself in that situation again.
Since we are talking these
It looks like we have 8 Ampere-Hours or so, and a 2 amp inductive load ( FSS solenoid on IP ), and you only need it for a few minutes.
Theoretically, you should be good for four hours.
I don't know if those Milwaukee batteries shut themselves down if they drain too far. One of the things lithium batteries hate is being drained too low...and this setup has no under voltage lockout at all. Pure simplicity.
I am not familiar with those batteries. They may have under voltage lockout circuits in the battery itself. This is only a heads-up over what might go wrong.
I'd go for a pigtail
And a 3 ohm ballast resistor
And run the wire to the FSS.
I would probably mount the resistor to any handy metal support member and tie all the electrical cordage down to that just to have some place to store it, ( and the resistor also functions as a mechanical stress relief to take unwanted tugs on the longer battery lead. Resistors are a lot cheaper to replace than IP connectors ). Just store it all in place and tied down out of the way awaiting the day you need it.
You probably have a handy spot to connect to ground nearby where you mount the resistor. The ballast resistance should swamp out the resistances of the lamp cord.
Terminate the lamp cord at the resistor and engine ground. The other end of the resistor goes to a connector that fits the IP.
In the event of disaster, unplug the IP from vehicle control and replace the feed wire with the wire coming from the resistor. Release the Hank of lamp cord with the Milwaukee pigtail attached, stretch it out ( 10 feet or so? ) Out the hood, over to the window, back into the cab, plug into the Milwaukee, and push away.
IDI BRONCO brought up an excellent point above. You have no coolant flow either.
Carry a spare? I am aware of these but I have never had any experience using one ..
The link that I posted, for the "stepdown" is advertised as working with the kids' cars.Or use the module. If it powers kid's cars ( motor-inductive load) ok, it oughta power a solenoid just fine.
