Or get a lithium iron and have the cranking power of a full size with less weight than a lawn mower battery.

Saving 15-20 lbs just doesnt seem worth it to me. Full size battery in the corvette is pretty small and was like 100 bucks, I think its like 25lbs or so, seems lighter than others ive had in the past.

Weight isn't really that important, but the slim batteries can be dropped down on the sub frame and just basically out of the way. May just look into putting the battery in the trunk as well and keep a full size. Surprisingly my battery did take the charge so ill see once i'm able to run and get a gas can/gas if it starts or if it's dead again.

Ahh yea thats right, lowering it down is nice to open up some room. Id probably opt for the trunk configuration, loved that in the M3. Came that way factory. Batteries last longer too away from all the heat of the engine.

Yeah I hear ya. For my DSM as well as my SC300, it's a size/space thing not so much a weight thing. I ran an Odyssey battery once. It worked about as well as my lawn mower one did, and lasted one season also just like my lawn mower battery. So at the end of the day I just stuck with the $30 lawn mower one. I dunno if it's because I run dual fuel pumps, and a stereo with a sub/amp bumping constantly that maybe drains mine faster than others, or maybe my slightly larger engine just takes more juice to turn over. My car always starts in the summer, but it doesn't crank as hard in a parking lot as it does in my garage after sitting on a tender. Not a big deal, but it's noticeable and makes you definitely think about it and make sure you don't accidentally leave a dome light on or something.

I don't know on DSM's because I've never done it, but relocating to the rear in the SC is actually very easy I've come to find out. So I'm definitely going to do that one of these days when it reaches the top of my to-do list so I can run a more normal sized battery again.

Well the car is alive, picked up some 93 from a shell down the street and with a little cranking the car started and surprisingly idled pretty good. Im getting some chatter from what im guessing is the lifters because they need to be pumped up and have been sitting for so long.(Went away). Few small things to fix up. Mount my catch can and should be good to go for June.

The 51r I mentioned fits down on the subframe, that's where mine is.

How are you guys having so many problems? My IX would start even in the dead of winter after being parked outside all night in below-zero temps with aftermarket cams and injectors. Scheides left his VIII parked outside in the winter for a week once while out of town and had no issues either.

DSM vs Evo. DSM's seem to have many more issues in the charging system than Evo's. I guess I never really had too many issues with either, but I've only had full size batteries in all my cars. I plan on running a full size in the Talon, but dropped to the subframe.

WooHoo! Great to hear! I didn't realize Shells were carrying 93 up there, but cool you found it.

I had a full size in the back in a Moroso box, then moved it up to the subframe as well. It was nice having it out of the way. I had the whole engine bay pretty stripped down back then.
