Ouch! $1500 is a ton for a battery, can't believe that Braille is only $250, not too bad, especially considering it's made out of CF. And at that point, 7.5 lbs. is not that much of a drop. I wonder how light I could go, considering my car does not have any electronics that stay on, and it's only a 3.4 I6. I wonder if I could get away with the 6.6....
Damn that would be nice, instead of my 50 lb. Optima, plus my car is nose heavy, so this could be a potentially great mod.

What would you guys recommend getting if I need to use my rear reservoir tank at the track? I was thinking of getting the 15 lb. battery for the track and when using the rear reservoir to circulate the water I would hook up another battery...too much work? Any suggestions on how to handle this? I could get the 21 lb. battery but reducing weight wherever possible would be preferred.

My rear reservoir is 3.2 gallons and is setup to run when the ignition is in the on position. I'm thinking of now getting the 17 lb. battery. What are your thoughts?

It doesn't really matter how big your reservoir is, it matters how much power your pump takes. Mine is wired the same way. Whether you choose anything between the 15lb and 21lb battery it wont really make a big difference in weight (6lbs is negligible) so if you are going to worry and stress with a 15lb battery in your car and feel safer with a bigger one then just go with the bigger one. 6lbs is not worth the stress IMO. I run the 15lb battery and haven't had any problems

FYI....
When you first hook this thing up, you're bound to see all sorts of failures on your MFD. I got warnings for ESP and cornering headlights. Plus my airmatic ran uber stiff. Twice as stiff as sport mode, and I even had my ELM turned off. I turned off my headlights, AC, NAV, and drove for 30 minutes. All problems solved. I guess they don't come completely charged from the factory and don't have enough juice to run all of the electronics.

Guys, my car still has its original battery and according to my tech, it is time to change it. The car does sit for a few days of the week. Is the 21lb best suited for me?
I was thinking maybe I can install a cut off switch if I park it for longer?
Thanks
Paul
