I put an Odyssey 1500 in the trunk of my race car a couple of years ago. I run a 50 amp alternator as required by the rules, but I charge between rounds during cooling anyway because of the electric fan and water pump. I liked it enough to buy pair of Die-Hard Platinum batteries for my 2004 Dodge diesel dually because they are manufactured by Odyssey, just relabeled - and less expensive!

I used Optima Red and Blue before with good luck, but now have the Optima as my auxilary trailer battery.
