What the heck is with Dewalt battery prices on ebay

[itron]

I'm not sure that's a good idea, Unfortunately i'm on the wrong side of the Atlantic
and the final cost would include custom tax Indonesia - Italy and Italy - US.It has to be a continental group buy.
Maybe you American could start first and let us European know how it goes..

Don't do it.

This guy is scamming you ... any money you send him via wire is gone forever.

His usual mode of operation is to sell multiple DeWalt packs, demanding a money wire up front.

When will people learn? Do not use Western Union unless it is to someone that you personally know!!

I just saw something on Dateline that said they not only scam you, but they steal your credit card info and then the real scamming starts.

when are they going come down in price by june???????

Why not move over to the Milwaukee packs? Sure they "only" discharge at 10-15C, but at $85 for 84Wh versus $130 for 76Wh... 1Wh/dollar versus 0.58Wh/dollar. For RC applications, the a123s are clearly better, but for our larger ebike packs, what's the issue?

Erm, that's $1/Wh vs $1.7/Wh

 

[curious]

I finished building my second pack - now dewalt prices should revert to normal

 

[manfred59]

Yes indeed the price of DeWalt packs with a123 cells inside is very high about $ 125 excl. shipping. United hobbies sell them $16,50 without shipping!
But I have read in another EV board about the K2 cells, similar to the a123 cells.
Who knows them? Are these cells really like the m1's?

and here is the test of these cells: http://zeva.com.au/tech/K2/
They sell them at $ 11,50 link: http://store.peakbattery.com/lfp26.html

As I understand it, A123 will last you at minimum twice to potentially as much as six times as many cycles.
$1.7/6; making it effectively be as low as $0.28/Wh.

I'll agree with that compared to Chinese LiFePO4 or average lithiums, but I'm talking about E-Molis. These are good, high-quality bits of kit.

To be fair, neither has been on the market long enough to get any meaningful measure of lifespan.

 

[Toorbough ULL-Zeveigh]

I stand to be corrected, but aren't Emoli's standard 500 cycle life 1000 tops? Compared with 3000+ for a123 as well as having a longer shelf life.
I agree it has yet to be proven in real life, not simply life cycling projections.
But the early indications from RC forums seems to back up that the Emolis lose their edge sooner.

 

[disadvantage]

Then lower the peak voltage that you charge your Molis to, for example 4.1V or even 4.0V, instead of the usual 4.2V

This extends their life dramatically. Anyone could do this with Gary & Bob's new 16 cell BMS.
