I'm running 4s1p a123 (built them from dewalt packs) in my Lightning Stadium 10 now with a Lehner 1930/6 and its getting 12-15 minutes of runtime on a charge. Its has real good punch too. Hard running of constant full throttle acceleration slow down for the turn and full throttle acceleration down the straight again in oval racing. Just about as hard as I can run it. They do drop voltage under the load, but thats why I'm running 4s with a 3400kv motor. The a123s take it well. The packs are for sure warm when they come out, but nothing alarming (around 110F)

I have 3 packs and it works perfectly for running almost constantly. I have one pack in the truck running, one pack cooling after the run and one pack charging. I'm using the Xtrema charger and charging at 8 amps so it takes around 18 minutes to charge fully. They just rotate around and it keeps going... and going... and going....

Next time I go out (hopefully friday if the weather is decent this week) I'll try and get an eagletree on a full pack run and post up the real world data.
Heres a link to the thread with pictures of the setup.
