Weigth loss: Battery

[Robert986]

I´m trying to put my Box on a diet, without sacrifying to much of the streetability (is that a word btw?). I use it as a Daily driver, but also take it to the track.

My present battery is 42 Pounds, and as we all know placed high in the car.. Would love to address this somehow.
I have looked into standard "racing batterys" Braille, Odyssey etc, but so far not found anything that feels right. So I started to look at Lithium batterys, that give a bit more drastic weight reduction, but they are quite exepensive..

Came across this: Lithium starting battery lightweight racing The first one I found with more reasonable prices, but would it really work?

Any thoughts?
