<div>Kurt,</div> <div> </div> <div>You can connnect anything together you want in series. It may not be a good idea, however. :-)</div> <div> </div> <div>Ideally, the packs should be the same mah capacity, and the same condition (identical cells, health, amount of use, etc). They do not have to be the same cell count. If you have mismatched packs, one pack may drop in voltage quicker than the other, and the LVC of the ESC will only see the series voltage and not the voltage of the individual packs. You could end up toasting the lower capacity pack.</div> <div> </div> <div>JMHO.</div> <div> </div> <div>Bob R.</div> <div><BR><BR><B><I>Kurt Bozarth <kurt@bozarthhomes.com></I></B> wrote:</div> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid"> <META content="Microsoft Word 11 (filtered)" name=Generator> <STYLE> <!-- /* Style Definitions */ p.MsoNormal, li.MsoNormal,
