You could use a leasure battery, the type they use in caravans. My local caravan dealer is doing 85Ah jobs for a little over £50, just to give you an idea of price.

When you buy it, depending on the shape of the 'posts' on the battery you would make a power lead that connects to one of those car ciggy lighter multi sockets, bear in mind when making the connections that the centre pin on a ciggy lighter plug is '+'.

A battery like that would keep you going for quite a few nights if you are only running a mount from it, but as with all Lead Acid batteries I would keep charge it after every use.

You could then get real fancy and build a box with all sorts of accessories in it, maybe Blinky will post a pic of his power supply, or should that be 'Pimp My Power Supply'? lol

If you have the celestron power tank you can take it apart and put a new 7AH battery in (assuming its the smaller of the 2 units). Just need to de-solder wires and insert new battery. Might be a cheaper option.

I've said it a few times now, IMO the best and easiest solution is to buy a couple of 20Ah gell cell batteries and an electronic charger.

They can easily be lifted in one hand re-charge pretty quickly and last forever if looked after properly.

The deep discharge caravan/ boat batteries are OK, but they also need a good electronic charger and are pretty heavy to lug around...
