Are 12V Power supplies any good?

I do the majority of my racing outdoors so thats what i was after. Is there nothing around like that?

Thanks for you help btw guys

there is somin out there, its called a 12 volt leisure battery

go to a good caravan store, 100amp can be had for £50, dont forget you will need a charger that maintains the 12 volt,, dont get a car battery they are different construction and designed for big bursts of power, not a constant drain such as leisure battery
