Batteries!

[krustyballer16]

Looking for the smallest physical sized AGM battery with around 500 cca or so...

 

Or less cca if less are needed to start my 6.0L ls "11:1" compression and 40° on the coldest day of be driving it.

 

I wanna try to save space and weight.

 

I've found a few brands (xs, stinger, odyssey) that have some 680s that say 1000 Amp max output and 150-350 cranking amps.

Some "racecars and drag cars" use this size battery so wasn't sure...

Maybe a power sports battery would work. I’ve run some 380cca agm batteries in jet skis before. lithium batteries save a ton of weight also. XS makes some nice lithium power sports batteries

Antigravity batteries are stupid light and compact, but the price is not.
