Simple elctronics help

It's been a fair few years since I've done any electronics. I was never brilliant. But I can't work this out.

If I have a device that is rated at 50A at 14.8V How many mAh would I need to run it for 30mins.

If I linked two in parallel, the voltage would stay the same but I would need double the mAh?

and if a battery is rated as a maximum discharge of 30A would that mean 10 batterys linked in series would be capable of 300A maximum discharge?

Also is any one into rc planes?
