Obviously, the 2 cell type needs a higher capacity (as measured in Ah) to provide the same amount of juice.<br><br>So doing a quick math with rounded figures and ignoring the voltage drop during discharge, you get about 103Wh on the first battery, and 98Wh on the second. That's a negligible difference and easily reverted depending on the discharge voltage curve.<br><br>Martin<br><br>_______________________________________________<br>music-bar mailing list<br><a href="mailto:music-bar@lists.music-bar.org">music-bar@lists.music-bar.org</a><br>http://lists.music-bar.org/cgi-bin/mailman/listinfo/music-bar<br></div></blockquote></div><br></div></div></body></html>
