Default Which NiMH Batteries

I just bought an OMP Katana V2 70 that I will be running 4 Hitec 5625's plus a Hitec mini 225MG on the throttle. I am thinking I would need to maybe go with a 2100 or 2300 mah NiMH pack and running 6 volts. Does this sound about right? Also, would I be going for AA batteries or something bigger?

Thanks in advance.

Once you go above 1650 It's hard to get a AA pack. If you really need a 2100 pack I'd go to an 2150 Series Sanyo 4/5 'A' pack. Check the weight.
Just my 2 cents,
John

Check out the NoBS batteries. I just bought two of the 1100's and they have other sizes as well.

Sanyo, Panasonic, Duracell and Energizer all have 2100,2300 and 2500 Mah AA Nic Metal cells.

I've been know to be wrong before. Guess I am again.

EDIT - > This is what happens when you make a list of suitable battery packs for giant scale 6 months ago.
Then you forget why you made it. Here I am always trying to preach about low internal resistance and then forgetting why I choose these batteries. Darn right embarrassing.

See Joe Airports post below.

1100 Series GP '2/3 A' Rx pack, 5 cell

http://www.hangtimes.com/sportrxpacks.html

Keep it light since it's a profile. This pack will last longer than a "typical" 1100 mah pack since it's internal resistance is only 7 milli Ohms. Most NiMh packs are around 20-25 milli Ohms. This thing will be great for high torque servos since the low internal resistance means very high discharge rates. It will yank those servos around with very little drop in voltage. That's what you want.
