Lightweight rally battery !

Had to replace the battery on the mrs's car so i gave her my one out the Uno and bought one of these

RMD Racing 25 Battery

Seems to work nice, cranking, lights etc, and is super small and light, i mounted my battery in the boot previously, so this hardly takes up any space, plus the lighter the car gets the faster and better it will be at braking!  

interesting only 5.4 kg that must b quite a weight saving on a standard battery what do they weight about 25 kg at a guess

I think they're around 15kg, its less than half size too

I'm trying to lose some weight for the next track day next month, gona remove the passenger seat for the day and a few other mods, if i can lose around 50kg should notice the difference!

That's cheap Rich !!   Odyssey batteries aren't that cheap.
