I was looking at a recent copy of Jameco a few days ago, and I discovered this:
http://www.jameco.com/webapp/wcs/stores ... tId=134237

It's a Li-ion D CELL that is RECHARGEABLE. AND ITS RATED AT 16.5 amps!!!! No, that is not a typo. Just two of these could drive even the most gas guzzling portables (Ben's PS2P for example) for more than four hours.
At about $16.00 a piece, you could make a 7.2v pack for around $35!! That's way lighter and less expensive than a comparable NiMH pack(which uses 6 cells instead of 2).
How to charge them, you ask? Since they are lithium ion, you could hook them up to a Infolithium(L size) charger. That should theoretically work, but if anyone knows a better way, let me know.

Whoah!

Thats awesome! I can't believe it's 16.5 Amps

That's a very cheap price compared to a normal li-ion battery.
This could be a breakthrough in portables!

Excellent find!

Once I get some money I'll have to buy two and see how well they work.

Anyone have a good guess of this battery's dimensions?

Oh, and could two of these still be charged with a Radio Shack RC charger?

These are the size a normal alkaline D size battery.
That's about 2 inches tall, and about 1.2 inches in diameter.

And no, you cannot use a normal NIMH charger. Lithium cells are a special case, where you have to have a computer controlled charger to monitor the internal structure. These batteries will explode if charged with a normal charger. I suggest looking into modifying a Sony Infolithium charger(or similar) that is already made for the application.
Look on Ebay for a good deal on one.

Cool, thanks. Yes more things to put on my wish list.

Sweet, nice find.

..........woah, 16,500 mah

.................I wonder if it could be charged with an Astroflight 109 Li-poly charger.....I sure hope so

Look again, there is a difference between Lithium and Li-ion batteries.
Who knows though, you might be able to use the same kind of charger.

Post by **Gamelver** » Mon Feb 14, 2005 2:24 pm

I sure hope so

.....even if it can charge lithium batteries, it says that the maximum mah it can charge is 8000 mah.....if it can charge these batteries, though, I suppose it'd just take a bit longer....

Whoa 85 AH!

er, I think it's .85 Ah............85 Ah on that one battery is pretty much impossible right now

.85

Whenever the voltage is 3.6 on a lithium, it means it is rechargeable. Unchargeable lithiums are only 3v.

That does make me wonder though, since it is such a high capacity, it might need a custom built charger.

Eh, anyways I might get me a couple and experiment.
