thanks guys think i scrap them batteries and go for something a bit bigger but i still like matts idea about two batteries. how heavy/big are the omnipole batteries?
the ones i have got are not that heavy and they have got a built in handle which makes it easier for carrying
why use 2 batteries when you only need one i would get fed up having to change my battery half way through the day also you would need 2 battery charges to charge them up at night
just get the one good battery.
