Just 1 point. The battery is 12V, 2 AH - Ampere-hour, which means it could supply two Amps for one hour (although you really should not make it do this as it would not be good for battery life - you should limit it to one amp.)
Good point. Thanks for pointing that out Paul. I was going on the original poster's comments and should have checked. Especially for Batteries which are only ever in AH.
