I have a good number of A123 cells for sale, new and never built into a pack or charged, with tabs, 2300 size.

I'll sell them at $11.50/each + shipping within CONUS. You can PM for a shipping quote, but I am going to use USPS and whatever it charges.

If you order 8 I'll sell for $95 shipped.
I realize that I have no rating on this forum, but if you're concerned at all, please PM and I'll show you my 100% rating on another forum.

Thanks!

I'm interested.

Can you give any more specs? Discharge rates(MAX, BURST & CONTINUOUS), and weight. Exterior dimensions too but not totally necessary.

Just to make sure. 2300mAh and 11.1volts right?

They're rated at 3.6 Volts/cell and you need to build the packs in a way similar to NiMH building. Their discharge rates are, in theory, 60 amps continuous/120 amps burst. In reality, 40-60 continuous and 80 burst is probably more reasonable. They are can-shapped and weigh about 74 grams/pop.

If you google A123 cells you'll find a lot of info on them--they're the same cells used by a123racing.com (that site appears to be somewhat down for some reason...).

The main thing about them is they are a bit heavier than lipo from a capacity standpoint, but can deliver at least as much power and are very robust. They can be charged easily at 4C (15 minutes), and some charge at 6 C or higher, for hundreds of cycles. They can be used for many hundreds of cycles without an appreciable loss in capacity and tolerate over-charge and over-discharge gracefully, unlike a lipo will will destroy itself if that happens.

Most decent chargers now have an A123 setting, but you'd need to look for that first to be sure.

Thanks!

I ordered 11 cells from JWilliams a week ago last Monday. I sent the money order out and 7 days from my mailing the cells were at my door in a very well packed box.
Very good communication and very fast service.

Hi guys, sorry and I do apologize, I have none left; I should have updated the thread title.

SJHi, at this stage I'm inclined to think not. The best source would probably be ebay and either the Dc9280 packs (8 cells) or dc9360 packs (10 cells)...

Robotic Power Solutions has them in stock.

James -- that link is dead. It's almost like the entire web site is down... :o

Didn't you tear apart a Dewalt pack to get to the A123 cells? How'd that work out for you?

Hmmm, links working for me? Maybe it was down when you checked it earlier, try it now.

I tore into Black and Decker VPX packs. They are 1100mah M1 cells. I shorted the pack out on the bench and never got a chance to fly it :blah:. I never did build another pack.
