I would like to know if all batteries that can be recharged get recharged at the same speed I am looking for a rechargeable battery that can get charge extreme fast thank you for any answers Kurt Stocklmeir -- --- Posted from http://lu7abf.org.ar/news --- news://freenews.netfront.net/ - complaints: news@netfront.net ---

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

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

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
