Greg,
I assume you are running glow & looking for a receiver battery. Most RCCA pilots have gone to flying 700 mAh LiFe 2 cell packs (Zippy packs) from Hobby King. They are currently showing as back order, but I would expect them to be back eventually. You can run them all day for combat without needing to charge between rounds (I've flown 10 rounds of combat on a pack a day). Make sure your charger does LiFe packs!
Watch your 6,
Andy
