Title: Starting Battery Setups/Carts
Post by: opa1 on August 05, 2018, 12:30:15 PM
Looks like I'm going to have to make a battery cart with quick connects to start my injected FED. What voltages are be used? Former owner of my car uses 24vdc to spin it over quickly. Pic's of your setup would be nice. It will give me ideas on what I need to build.

im going to use my golf cart as battery supply to start the FED.  no sense in spending a grand when you dont really have too.  i think eventually it would be nice to have a separate kit if needed.. say for starting at home when the cart is in the trailer.

i think on the starters you can throw 48 at them, assuming its a blower type starter.  just makes them spin faster.  i have a chart from the person that built my starter showing starter type, voltage, and rpm.

Put a 12 volt battery in the car and use a block mounted starter. If its a MSD mag you might run a 16 volt battery. We use a Powernaster starter on 12 volts to start our 377 SBC w/6:71. We began with an external battery. Its a hassle unless you buy into the compact batteries.

When we had a block mounted starter on our car we used a TCI starter and two PC680 Oddysey batteries wired in series to create 24v this set up worked great for us for quite a few years

I have a new Braille 17 battery in the car and a hi-torque mini starter. It was enough to fire the car today. I might not need the starter cart. I did have to prime the pump by pressurizing the vent tube in the fuel tank. After that it started right up. I'll see how it does when I run the car. Thanks for the tips.

This is what I use which sounds the same as Paul used. It is quick,easy on the crew, inexpensive and lasts about 6 years.

I like that setup. The Odyssey batts are AGM so my charger would work. I'll have look into it.

That is nice. I think i'm going to buy 4 of them for my blower starter. i hate my battery box...too heavy.

So if you wire two twelves in series, can your ignition, water pump, etc. handle 24 volts?

You are just using the two batteries for the starter.(plug the batts in, start, unplug batts) You would have a separate onboard battery for the electronics.

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,
