Lithium Ion batteries

xul · Oct 26, 2011

Anybody have experimental data at room temperature for discharge rates above 1C?
The Peukert numbers only work for batteries at constant temperature during discharge, and Li batteries heat up.

I'm sure by fussing with Excel I can come up with an equation that characterizes these batteries for sizing purposes when used at high discharge rates.

TIA.

I am also waiting for the data for about 18650 li-ion battery.

Thanks for it in advance.

Perhaps this would get more attention if it were put in the section titled "Flashlight Electronics - Batteries Included"?

You can always check my website, there are lots of LiIon battery test all made at room temperature, but I do nothing to prevent the battery from heating up.
