Look at this page of a graph of the Polyquest XP cells (these are the same as the Hyperion Litestorm cells): http://www.elektromodellflug.de/akku-test/polyquest.htm
You'll have to scroll down a little bit to get to the 3700mah.

Oh, I see. That pic didn't load until I opened it up in a separate browser.
I think I've read that the Orion and Peak Lipo packs are 2p, and not single 4800mah cells. Unfortunately, I don't recall the source of this information.

Thwe Orion packs are indeed Kokam cells, configured in 2s2p. I plan on using the Orion cells this year myself. The packaging/size etc. is perfect IMO, and the extra runtime form 4800mah is a nice bonus. Also, the Orion 4800 packs are around $150 each.
