Battery relocation using Optima battery

do I still need a battery box to contain any fluids?

Are you doing anykind of racing that the rules say you need one. I have used Optima's in the trunks on the last two racecars I built. I always put them in a box just to protect them. I think it looks cleaner too. But as far as I know there is nothing liquid wise going to come out of those batteries. I ran one in a solid chassis roadster (old funny car chassis) with no problems at all. It took alot of abuse over the rearend from tire shake and bouncing. I like those batteries because of the way there made. If they could get more amps out of them the would be the best thing since sliced bread. There is a picture of my setup in the link below.

What do I do with the ground cable up in the front when I move the battery to the rear ? I know I have to ground in the rear. Any other suggestions when moving the battery ?
thanks

Fastlane, there is alot less outgassing with the Optima but it is possible. A more important concern is the chance of a spark that close to gas fumes! I would put any battery in a sealed and vented box, especially if your running the stock gas tank.

You might want to relocate the ground to the shock mount in the back.....that is a popular place. It would be wise to ground your engine to the chassis in the front as well. Fuse the main power wire too, with a fuse higher than your alt but not too much.
