Yes i can understand the confusion...
Capacity and draw rate are two different things...
the "Ampere hour" rating tells you how long your batteries will
supply a given current...this is the battery capacity
However....
batteries don't like being charged or discharged too quickly....
(too great a draw rate will reduce their lifespan)
So you need more of them in parallel to spread the load....
...and when you do this, it also increases your capacity.
(there, now i have cleared that up ;-) )
