Best battery choice?

[Henderson,Eric]

It's not a better battery argument - it's a weight issue....

There are plenty of us nicad stalwarts!
Mark, I agree with your reliability/convenience assessment.
My 5-cell SR 1000 mAH is good for better than 5 flights, as I have
repeatedly measured the consumption of a all-digitals practice flight at 145 mAH.
I'm considering going to a 500 pack and after every flight top-ups with the Sirius.
That gets the weight to the point where any disadvantage to the nicad is, in my opinion,
greatly outweighed by their reliability.

Lol....ok Anthony...then there's two of us flying Nicads.  I use some of the newer technologies for my electrics, but with regard to Pattern, the new batteries appear to fix problems I don't have.  I run a 5cell 6v 1400mah nicad pack.  I personally haven't heard an argument that even comes close to making me want to change.  Cost/reliability/convenience all seem to favor Nicads.  The only one against it is weight.  And from my perspective, if I need that ounce...I have bigger problems.   Just my .02...I'd love to hear others opinions on the subject...

It seems like every month a new battery technology is introduced. NiMh, Lithium ion, NiCad etc. Each one claiming to be better than the last. It seems like I am the last pattern flyer still using old familiar, heavy, memory burdoned NiCads. I am considering investing in updated batteries and all of the other things needed to maintain them. I have accepted that I will need not only the battery, but a new charger, regulator, and all the other fixins. Given that condition, what is the latest info pro and con on the new battery technology. I know there was an availability issue with the duralites that has seemed to be resolved, then I remembered hearing something about them overheating or blowing up or spontaneously combusting or something. My point is, there is a lot of misinformation out there and I am trying to find out what works best from those who use it. 
In order of importance of features:
1. Reliability
2. Weight (lighter is better)
3. Capacity, can I get 5 flights on them, can they be quick  charged?
4. Durability / margin of error / expected life span. If I leave the RX on do I have to replace them?
5. Price
6. Availibility  

I appreciate any information you guys can provide.
Thank you.
Anthony
