A long time ago we had two small batteries mounted on our old car to create 24 volts we just hooked our accessories to one of the batteries to get 12 volts

MSD says their stuff is ok with 18v, but not 24v.

I run my onboard stuff off a Milwaukee M18 drill battery.

A few years ago we moved from two 12 volt car batts in the back of our truck and long cables, problem was moving the truck in place, and getting out of the way.
Then I made to two Odessy batts that we could take out of the truck.
Then I made the lightest battery paks using litheum batts that with a  alum carry case weighs 10 lbs with cables. For one reason all of our crew are close to or over 70 years old.
We have been using the Hayden light weight battey paks for 5 years.
We do run an on board 14 amp battery , that weighs one lb to power the RacePak and trans brake.
One idea I've been working with a Heritage AF team with a blown Alan Johnson Hemi is running the two Hayden batts on board that uses a hi-torque flywheel starter, that works Great, we also have another Hayden Pak to plug in if any crew forgets to keep the on board batt charged up. My idea is Heritage AF can only run Heritage races, but if the FED is self starting he could run some Top Dragster races, IE more TNT and seat time.
The point I'm making is any blown car could use this system with out the hassle of using the blower starters. Yes, the on board batt's weigh about 8 lbs total, but if you don't need to get lighter, all you'll need is a crew member with a primer bottle.
Let me know what you think,
