Sounds like you've purchased wisely Ken. A mount and guider shouldn't draw more than 1amp, unless you're slewing all of the place continuously (which usually isn't the case for imagers).
Max discharge down to 33% gives you 26ah, which should give you at least 2 very long nights of imaging. Recharge as soon as you can, and trickle top up from time to time. Sounds like you already have a good charger which is very important.
I've bought from Aussie Batteries before with no probs at all. You can always buy an extra >100ah 2nd battery in the future if you start running dew heaters, laptops and other juice hungry beasts!
