This Friday, I was bumped from the B main to the A main in the SC10, and I forgot to hit the charge button after hooking it up while I went back to the track for the buggy main, but the 5200 pack had enough juice to finish its 2nd 6min main without being topped off.

I do have a Dynamite 25C 6000Mah pack I keep charged on the side just in case, and use it for practicing as well. I'm planning on getting another 5200 SMC Lightning Volts as a backup too.
