No. It's not so much by chemistry -- there are both fast and slow charging NiCd cells, LiPo cells, etc.

How fast is "extremely"? Getting a full charge on a NiCd cell in 10 minutes is doable. I don't think there's many LiPo cells that can charge that fast, at least not without occasionally bursting into flame. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com

** Only one I can suggest are Panasonic Rapid Charge types. Back when I did some 1/10th scale car racing ( track and velodrome) Sanyo NiCd cells were the only ones that coped with 15 minute charging and 4 minute race times. The best were their SCR types. Now, Panasonic make the same types. http://industrial.panasonic.com/www-cgi/jvcr21pz.cgi?E+BA+3+ACC4003+4++WW .... Phil

No, they are very different.

Extreme is a relative term. You can easily find batteries specced for 8C charge rate: http://hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=19128 That means that you can theoretically charge them in 7.5 minutes. In reality, we're talking 12-15 minutes if you want them fully charged, since you cannot charge at 8C all the way to 100%. Since you do not specify any capacity or voltage requirements, a cpacitor will handle extreme charge rates. -- RoRo
