Just wondering...why the heck are Li-Po batteries so dang expensive?

Will 'competition' from the A123 drive prices down or is there something in/about a li-po that just fixes the cost at a premium?

Penny for your thoughts

A123 is not that much cheaper. Its only when sourced from dewalt tools that they become a bargain. Have you seen the cost of the A123 racing packs?

I guess not.

What's the difference? (Dewalt do the work yourself and A123 Racing packs)

I've just seen that I could purchase 2 6cell A123 packs made up with balance taps and a deans plug for about $290.00...that seems like a heck of a bargain to me.

Don't get me wrong I have already been converted and run A123 in two of my helis. 10s in a Logo500 and 12s2p in my Joker2. The point I was making is if it was not for the Dewalt packs they would not be as reasonable as they are. Here is the proof in my view. This is from the A123 site and shows the cost at 3 times what they cost the 'other way' from a well known auction site.

If lipo had a similar use in power tools then I bet they could be sourced for cheaper too but the lack of robustness and tendency to ignite makes them less attractive to that market I guess

Until something else comes along which is aimed directly at modelers and at a lower price then Lipo will remain expensive I think.

Thanks Fergus. That makes sense. Good ol' Demand and Supply really.

How do you like the 12s2p setup in the Joker (did I read that right? 24 cells total?)

24 cells...nice

I can't wait to get my Joker in the air.

A123 seems the way to go.

Yes 24 cells- 12s2p A123 is similar to 10s 5000mAh lipo. It is heavier so will not have as much punch as a Lipo setup but is perfect for my level of flying and gives 10min flights with 15 minute charge time.

Do you think 10s2p A123 would work in the Joker for shorter flight times?

6-8 minutes of aerial photography?
