$830 for a battery, ouch. It is 14#s though. That is some major weight savings.
The lithiumax is less than half that price.

Are you sure you don't mean recovery tank/ice tank?My thought is to try and mount a relatively large water to air heat exchanger at the rear as a bit of ballast
Yeah, I mean what I said, just an experiment though, I can go back to front mount if the rear mount is completely ineffective
If it works, it could be a novel concept for some track guys that have issues with cooling due to limited frontal area/intercooler blocking half of the radiator.
I think he is assuming your bathroom scale is in lbs... 24kg to lb = 52lbs for the stock 760cca battery.
The Li battery is about 7lbs? Sounds about right for that CCA. You can get a 400-500CCA Li battery that weight about 5lbs for $200. That will crank the car just fine in warm weather. If you really need to drive your car in the winter it wont work well at all (I've tried it) but you can just drop the stock battery back in.

Lithiumax batteries on the other hand are designed for automobiles and have considerably higher Ah capacity and sophisticated BMS systems for that purpose. We also have a motorcycle/Powersports battery that has enough punch to start high compression V8s but there is no way we would recommend that for anything other than a small Formula, open wheel race car, for ultimate light weight, as weighs only 800g (2lbs).
Lithiumax are opening in the US next month so we will be able to ship by road to 48 States and Canada from December/January.
