Kinetik Batteries

[sik68]

I am wondering if any of you have experience / comments about these batteries. I was talking to my local speedshop about Braille (light weight, good cranking and durability) and he mentioned that he's a dealer for Kinetik.

Here's their audio website:

and racing website:
http://www.kinetikracing.com/



The racing site is "under development" but here's their catalog.

Looks like the KR912 (22lbs) and KR1212 (28lbs) are the only light-ish batteries...but they don't mention cranking amps or amp-hours.

Thoughts?

Thanks,
Steven
