Default Power recommendation for Rappy 50

Anyone have a recommendation for a good battery pack for a raptor 50? Size? Volts? Type? I'm leaning towards li-po, but thats not set in stone.

Thanks!

I have Duralite Lithium-Ion 4000mah in all my helis. I can fly my R50 all weekend on a full charge. They aren't cheap but I think it was some of the best money I've spent on the thing. With a 5.1V regulator with a fail safe switch you get basically get dual battery packs and no switch failures and a LOT of flight time for your money.

The regulator has the switch wired to it. The switch shuts off the regulator. If you cut the wire going to the switch (or if it failed) power to the regulator stays on. Hence a switch failure would only result in you not being able to turn the reciever off. With a switch where the power goes through it on its way to the reciever, if the switch fails open, then no power to the reciever and helicopter immediately seeks mother earth or something attached to it, or worse, flys off into the setting sun.

If you have the money go with a lithium battery. If not, get a NiMH battery of 2000mah or higher. I run a 1950mah 4 cell NiMH pack in my Raptor 50 until I can get a lithium setup.

You might consider reading over the info on the Hangtimes hobby website. Steve has a lot of great info there on batteries and why to choose 1 or the other. He also has great prices, services and the best battery packs I have seen in my 23 years of R/C.

Here's the battery I am using, Sanyo 1950mah NiMH:
