1200 E-techs would be a good choice for your requirements. Bishop Power has the old E-techs for 22 bucks a pack right now I think(2series). That's about as cheap as you'll find them. I have the Apache 2500 charger and have been very pleased with it.

If I run my 1200's down to where the heli only has power to remain in ground effect, it takes about 1 hour 20 minutes, give or take a few minutes on the apache2500. That is, out of my 4 Lipo chargers, the fastest of all of them.
On my set up...I run both brushless main and tail motors...I get about 14 minutes hovering.. I fly for 13 minutes in forward flight, fast forward flight, and aerobatics out side of course. I like to leave a little reserve battery capacity to be able to land when I want it to land...

Thunder power 1300s are better packs than the etec 1200s (longevity and power). I have some of both (2s and 3s) and the TPs have more juice for about the same weight. Worth the extra cash? Buy some of each!

Of course if money were no object I'd certainly recommend other cells. But the E-techs seemed to fit Sworrix's criterea....hmmm criterea....is that spelled right ?
Personally I don't want to play the 50 dollar battery pack game again. I'll wait for the price to come down.. Having nearly 30 Lipo packs now..I can afford to wait..
I do however really like the Apogee 830's. If you don't mind the shorter flight times, these batteries have the best voltage under load I've seen...in their catagory...and they're fairly reasonably priced..
The 2 series TP..you mentioned pbmax, seem like the next best thing regarding cost vs. performance. How much do the 2 series TP 1320's weigh ? Are they close to 60 grams ? But again, they are 13 dollars more per pack than the "old" E-techs. Anyway, if money were no object...definitely go for it. I always say, buy the best you can afford.

http://www.allerc.com lists the etec 1200 2s packs at 51 grams and the TP 1300 2s packs at 60 grams.

The reason I bring up the TP packs is that they supposedly last a lot longer than the etecs and are able to provide significantly higher current for longer w/o damage. Some pretty experienced electric heli pilots I've seen posting swear by TPs and claim that etecs lose capacity too soon.

Myself I can attest to the higher juice of the TP packs (both 2s and 3s), although my 2s etecs have lived through almost a year of abuse now (30 - 40 minute flights in my carbon falcon, lots of heli time) and are still pretty strong. Bang for the buck, I think the etecs win, but the TP 1300s offer a compelling alternative...

I'm more of the "invest now" mindset - getting the good stuff first instead of slowly upgrading and spending more cash in the long run. I've gotten bitten by inexpensive stuff too often!

30 lipo packs? Geez, talkin about unlimited budget I have 6 - 2 etec 2s 1200s, 2 etec 3s 1200s, 1 2s TP 1300, and 1 3s TP 1300.

I have a large number of hacked together surplus ion packs, but these are only good for maybe 5 minutes of heli flight time (10 with a brushless setup) and 20 minutes or so of airplane time.

Supposedly the best out there are the Irate and Tanic packs. I wouldn't know as I haven't tried either.

ahm,
with 30 packs that's a lot of flying! how do you keep them all charged?????? i only have 2 so far and i'm already thinking about not wanting to wait....

pbmax,
i've been bitten that way too (buying cheap and needing to upgrade) but i got hit the oposite way (planning ahead and somehow loosing something) when i got a spare battery for my laptop... partly my fault - i left it on the shelf too long with a full charge and without cycling it and the "smart" battery was smart enough to declare itself dead. now i don't think in long terms when i get batteries, but i do look for deals, like when i got my hornet2 i got 2 3s etechs at a discount rather than 1. and that's what helped me be ready for my hb cp setup. so i guess did look to the future too.

pet_heli, I keep them all in a charged state..ready to fly. Very easy to do since Lipos really hold their charge over time. I have 4 Lipo chargers at home and can charge 4 packs at a time in 2 hours or less. I have never used all my packs in a day of flying.
When I got into E-flight, I wanted to ensure I had enough batteries to avoid field charging..especially since it really isn't time practical with Lipos. Last summer, I worked about 70 hours/week at my job. This afforded me the $$$ to stock up on Lipos but left me little time to fly. This season will be different ! I have mostly E-techs, a few older gen. kokams and just recently added some Apogees to my stable.
That's why I recommend the older gen. E-techs if you just want some cheap(er) fun for your heli. I've gotten great longevity out of mine(all my original E-techs still have "like new" capacity) and at 22 bucks for a 2series pack...that's as cheap as any 6C Lipos will get.

Yup, those are the correct batteries.... proceed with caution though. I've always gotten good service from HH, but there are some seriously disgruntled folks here that can tell you stories...hehe
