Is there such a thing as Nano-phosphate or is it just a myth / advertising gimmick? A few quarters of Inorganic Chemistry and I don't remember any "Nano-" Prefix being used for chemical composition. I know Phosphate is PO4 and can be 1-, 2-, or 3- but the only use in real science of "Nano" I can find is as a unit, 10^-9. I know some companies like to spew out junk science made up of futuristic sounding words b'cos a section of the population will take their word as gospel; but that doesn't mean the rest of us should just accept something that doesn't really exist. Anyone?

I think the name is a gimmic (Nano-Phosphate Lithium Ion), but there is a HUGE difference between A123 Systems battery cells and other Lithium Iron-Phosphate cells out there. A123 Systems cells are rated for 30C discharge while other rip-off brands are only rated for 10C discharge.

Sorry I forgot about shipping. Add one dollar per cell. Purchased August 11th. Perhaps since then they are becoming more popular and bids are going up. Or less are available. I haven't seen the prices of them lately, but have a few I started watching yesterday cause I might buy another pack.

I just took a quick look at a buy it now price for two dewalt packs. It was under 14 USD per cell shipped. Still not bad.

I don't think the "nano" moniker on these cells has anything to do with the chemistry, that part of is is marketing hype. I believe that the "nano" refers to the cell's internal structure taking advantage of nanotechnology in aligning the molecules on the cathode material somehow. I'm a hobbyist, not an EE or a chemist, so I don't claim to fully understand exactly what they're talking about, but the idea is more efficient electron transfer like can be obtained from nicads by "zapping" them.

That's what I meant, Marketing hype, junk science, or both. It's no more nanotechnology than modern supercapacitors or carbon-fiber. At best you should be calling it something like "nano-meter structure" or such.

I bought 4x cells and installed them into my rc car. I got this: [link=http://www.youtube.com/watch?v=L7XRed-UzwQ]http://www.youtube.com/watch?v=L7XRed-UzwQ[/link]
