I wanted to see if anyone would be interested in modules of the 26650 A123 cells. These are what I have come up with for my application and power requirements. Each module is 3.3v@115AH, possibly with a built in equalizer if you would want that.
We all know the capability of the A123 cells, which is why I chose them. These are new matched cells, not seconds or reclaimed dewalt packs.
Pricing will be $325.00/ module + shipping, no overseas shipping. Modules with equalizer will be a little more. I'm testing the water to see if there is serious interest in these. Please contact me via PM if interested.
Thanks

Pricey...

Yes, However there is no substitute for quality. These cells are manufactured to the highest standards and they follow all patents, no knockoffs. These cells produce power on a level the Thundersky and other manufacturers dream about, 52c pulsed 30c continuous, can also be taken to 100% DOD without damage, quick charged in 15 minutes to a full charge with no damage. The only manufacturer even close to this quality is PSI who makes the Lifebatt product, which is also very good and worth the cost. There is something to be said for having that kind of peace of mind when investing in a battery pack. Knowing to that you have purchased a product that is made on the up and up, no cutting corners or cheating in the process.

Nah, greater than three times the expense of others that Technologic, David85 and others are testing. While I appreciate quality and American made goods, I won't pay that kind of price if my family made them.

There is a place for these kind of cells in high power applications. I use the A123 cells everyday in an electric bicycle and I only have three packs of twenty cells in series that are paralleled together, so 20s3p cinfiguration. You could call it a 66V, 7ah pack and it weighs under ten pounds. I routinely discharge it at 60A and the voltage holds at three volts per cell with no problem.

In an application where weight is a huge factor, like a motorcyle or a bicycle these cells are perfect. Probably not so useful for a vehicle where you can handle the extra weight.

Great batteries ideal for small applications that need lots of power. But it is pretty hard to build a reasonably-priced electric car with them.

However, I am pretty happy to hear about that price . . . it is below the $1000/Kwh mark, so that is very good news!

$325/(3.3V * 115AH) = $856/Kwh

I'm not certain I follow the extra weight statement...
My modules weigh in at 8lbs a piece, my total pack is under 400lbs, compared to LA that's a dream come true.

What I was saying is that an electric car can handle the extra weight of Lead Acid or some other battery type easier than a car.

I use the A123's on my bike and you would have to pry them out of my cold dead hand to get them away from me, but I don't use them in my car because 530lbs of lead for $2000 gives me all I need.

If I was building a car for all out performance then it would be A123, but I just need it to go ten miles a day and keep up with traffic. It does that and more, so no reason to pay for something I don't need.

Oh I see.
Yes I'm going for all out performance, that's why I am building from the ground up. I'm glad you have real world use of the A123 cells and speak highly of them.

[david85]

Its encouraging to see a123 cells below the $1/wh mark, but prismatic cells are falling in price at the same rate, so its still about twice the price of prismatics.

I can appreciate the idea that these cells have much higher C rating, but in reality, we still don't have much in the way of motors or controllers to match them, so it's hard to justify the price.

wakinyantanka, I won't ask for your source, but I am curious to find out why these cells seem to be available all of the sudden. Last I heard if anyone wanted to get these cells in their electric car, they were forced to buy up a whole mess of Dewalt 36V batteries and tear them apart at a rediculous cost.

What changed?
