I ordered from Towerhobbies a receiver battery pack for one of my airplanes, a HydriMax Ultra NiMH 750mAh, because I wanted a bit more assurance that it would not drain off as I was using one servo that was digital. To my surprise the pack is made up of 4 AAA cells not the usual AA size. I was wondering if this pack would drain quicker than say a 750mAH NiMh pack that was made up of AA cells, even though they are both 750 mAH?
