bascily what you can get is a motor home battery.
i can get one for you. but postage will probably be a killer.
i can get the nice big ones for round 30 pounds max. i also havone that you can get off me. it is 1 month old and been used once at a meeting and then charged right up again. the bat lasts the whole day with the sure start heater on all day.
cheers
