You will cook your batteries! Some people have used 4400 ma 20c batteries (88 amps) and they still puffed. The 600 needs a good battery like flight power or thunder power 4900-5000 ma. The Trex 600 can peak over 100 amps. The only way you could use the 3s 2200's would be to use 4 packs with 2 in series and 2 in parallel. This would give you 22.2 volt @ 4400 ma that might last a while if they are good batteries.
