+1 for the Shorai lfx36 (540CCA) or lfx27 (405CCA). Have been working great for me and both less than 5lbs. So far plenty of power and only downside is having to hook it up after a week, etc. I'm using the Shorai battery maintainer.

A few of my buddies have this on their street cars too. Works awesome in my car, never have issues with it starting. I do keep it on a battery tender once temps drop below 40 degrees.. Car fires up within 1-2 cranks. I shaved close to 50lbs. Best money for weight savings!!

that is nowhere near the capacity of the one braille sells. i understand the desire to go with a lighter option but you can't ignore sacrifices when you make them
