A123 cells galore..
 
Ebay auctions

$70 for 12 cells, I make that $5.83 a cell, plus ~$20 shipping. If you can find a better deal than that, I'll eat my socks. :yes:

Now only if they weren't so big. And heavy. And if they had better capacity. And if only they came assembled. Then this would be a steal!:yes:

Can they be flattened down so they match normal lipo form factor?

Metallover 05.28.2009 06:39 PM

wow wow wow

Woot! Thanks Neil! :yipi: I've been waiting for a deal to come along. If I could afford it I'd buy a few packs... but 12 will do for now.

LOL @ BrianG- I suppose you could hit them with a hammer, but that might not do them much good. Its just a shame they only really fit emaxxes and 1/5 scale stuff, but then again, everyone has an emaxx dont they? :wink:

No.... .. . :cry:

Good deal. Are these genuine A123 cells or some chinese knockoffs?

What's_nitro? 05.28.2009 08:23 PM

They bear the copywrighted A123 Systems logo, so I hope for the seller's sake that they're genuine.

I have a 50 ton press... I can flatten them to any size you want... no guarantee they still work when done though. :lol:

Just run 1p, they are like 70c cells right? I am sure the voltage drop is not that bad...:whistle:

BL_RV0 05.28.2009 10:13 PM

Says those cells are 10C, 70A cont. Not sure how they got that- If they were 10C wouldn't you get 23A cont? If they do deliver 70A cont, the cells should be about 30.4C.

I think they are referring to a 10c charge rate. I think.:neutral:

Product Feature
Nominal voltage: 3.3V
Nominal capacity: 2.3Ah
Core cell weight: 70 grams
Internal impedance: (1kHz AC) 8 mΩ typical
Typical fast charge current: 10A to 3.6V CCCV
70A continuous discharge
120A, 10 sec pulse discharge
Cycle life at 10C discharge, 100% DOD: over 1,000 cycles
Says 10C discharge...

Metallover 05.28.2009 11:50 PM

hmmm... I think that's for testing the life span, not the maximum continuous rating.

"70A continuous discharge
120A, 10 sec pulse discharge"

70 ................120
2.3 = 30.4c....2.3 = 52.2c
