What do the racers run for a battery? I am looking to shed weight but still have enough to crank it over.

I be more concern about getting the weight distributed to get the car corners balanced. I would suggest that u reloate to the trunk getting weight off the left rear.

Bob Slusher suggested this one. it looks perfect. Light and has enough power to start the engine.

You might want to consider this one also- for only double the price it looks like you could chop the weight another 73%!

I just found it... this looks like this might be my next battery as it only weighs 4 lbs and would appear to have plenty of juice for starting. Lithium ion batteries really have come a long ways!

I was thinking, moving the battery to the trunk is a popular move, but you also have to add battery leads running to the front which will add more weight overall. Makes me think going with one of these super light batteries in the back would be better overall.

For our Drag cars we use lipo motorcycle batteries. Honestly feels like they are empty. We run 2 batteries to get the cranking amps and charge between rounds. Ours are older and don't like a standard car charging system. I hear the newer style has a built in converter to work with an alternator. Think they weigh 1.5lbs each.

We use a very lightweight cable for the run. it is feather light. Weight in the front is good for road racing.

I agree with Odyssey batteries. I had one in my race car, Lotus Super 7, running a 13:1 compression ratio 2.0 L. It was 14 years old when I sold the car last year, and still cranking like new. One drawback is these gel type batteries don’t like cold weather. One time at Roebling Raceway the temperature in the morning was 36 degrees and the battery would not crank. 2 hours later, temps around 54 degrees and the battery came back to life. Battery was around 6 pounds, measured around 3” X 6” X 6”. Cost is around $180 now for this battery.

I spent about $100 3 years ago for a tiny Lithium Ion battery for my motorcycle. It will barely start it now.

What kind of battery box do you run when using these small batteries? Standard boxes are all for group 24 sizes and up. Seems like too much empty space.

Mine used an aluminum strap holding it down. It’s a gel battery so the position of the battery isn’t important. Mine laid down on its side. For SCCA racing, I needed to cover both terminals with a small piece of duct tape.
