Ok car has one 12v Braile battery now.While it cranks over so so,its not as strong as it needs to be. I can add second 12v and cars is setup for it.Next option is 16v battery. Have heard lots swear by 16v. I know its not wiring.Same voltage at starter as at battery,used o wire thru out.  Starter being problem is possible 2 braile's weigh almost same as 16v.While adding weight sucks,it is in front of axle center line,so not terrible.

 Wondering what others are running with on board battery?

If i was going to carry a battery, it would be a 16v.

Chris You will see a big difference with the 16 volt ! It will crank a lot faster ! The down side is weight and you will need a 16 volt charger !

You may want to consider a Marine type 12v battery with over a 1000 amp rating.

Marine battery way to heavy. Already have a 12,14,16 volt charger and from reply's on DRR  and Bill's seems 16v is deal to go with. Yes its more weight,but about same as two Braile 12v. Plus it is out front and we know FED's never need nose weight.LOL  Hate adding weight,but at same time have to be able to depend on car cranking when in line.My luck it would only screw up in semi or finals of big money race and cost me 10 time cost of battery.
