You can add a 10 AA battery pack to the Scorpion, that's been discussed before. If you need a ton of extra sounds, just load up another SD card and trade them out whenever you want. That'll give you 400 sounds, only 200 at a time control from the remote though. Of course, you'll have to plug in your remote and download whatever the new soundlist is on the other card, but that's not a big deal.
