As a rule, it seems that for equal capacity, pb is 10x the weight for 1/10 the cost of Li. Li options do not supply as much current so the max power out (P=IE) is limited.<br><br>For Pb conversions, you should estimate 1/3 of the GVW as lead. Too much will cut your range, too little will (of course) cut your range.<br>
<br>50 miles at highway speed will take some effort.<br><br><div class="gmail_quote">On Sun, Jul 6, 2008 at 11:44 AM, Mike Seningen <<a href="mailto:mseningen@austin.rr.com">mseningen@austin.rr.com</a>> wrote:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

I'm reading -- Pb are cheaper -- but heavier<br>
Li Ion are getting cheaper -- but not there yet.<br>
<br>
One of the problems with reading internet articles -- is that there are<br>
rarely time stamped -- so<br>
you really don't get a feel for what "not there yet" really means.<br>
<br>
Can someone point me to prices for Pb, and Li Ion batteries/packs to<br>
continue my homework.<br>
I'm trying to get values to plug into a spreadsheet and see what my $$$,<br>
and weight deltas would be.<br>
<br>
Assume I'm looking to do 50 miles, at highway speeds in the Hill Country<br>
on a single charge,<br>
make up of 2 or 3 equal distant runs.<br>
<br>
merci!<br>
