That's what I figured, pretty valid reason for your choice. I've never used an Ares so I can't comment on their internal quality, but if you really want the increase in rof and trigger response of an 11.1v battery and can afford to fix/replace parts with stronger components if they happen to break, I'd say go for it. If you have never used lipo batteries before, just make sure you get a good lipo charger/balancer as well.
