The battery you described should work just fine. I run 1800mAh 15c's and 2200mAh 15c's in my T-28. Like biged point out, it is the motor and prop combo that will determine how much current is pulled out of the battery.

Just make sure that the battery you get fits snug in the plane. It has a pocket that the battery slides into. Basically friction holds the battery in place. Having the battery in this spot usually sets the CG right on the money.

You'll love the T-28. I wouldn't necessarily recommend it as a first plane but for a second plane or even a 100th plane, it is great.
