I am running the same setup as you a CC54 and Don's 4800kv.. BTW I checked this setup on my power analyzer and it pulls at max 397 watts and 38.8 amps which is no where near the max output for that ESC.. As far as the battery I am using a 2200 Mah 25c battery which is capable of 55amps cont.. Of course there is the one issue that it got hot enough to cause the velcro tape to come loose and fall out of the plane.. Next time I am out I will get some accurate temp readings off the battery, but my guess it was around 120 degress as on the third run I did a feel test and it was warm but not damaging hot.. BTW if you are using the stock velcro you might want to look at a better way to secure the battery ..
