You mentioned 2-2 1/2 hour run time and an equal amount of time to charge.
Almost all batteries are designed to safely take a 1C charge which means a 1000 mah is charged at 1 amp, a 2000 mah at 2 amps etc.  At a 1C rate a battery should charge in 1 hour.
Many batteries are in fact designed to handle a greater rate of charge.  
Also, if you are getting 2 1/2 hours on a 2000 or 2200 mah pack your engine is drawing less than 1 amp.  Not bad for the large O scale you describe.
