So took a quick look at the Braille website. Battery that seemed most suited to our cars was 15lbs and about $168 regular case or $275 carbon case(suppose to protect battery from engine heat). Battery can mount vertical or horizontal and they sell an aluminum mounting case for $75. They also had lithium ion even smaller for close to $2000 lol.
