Sam, The range would be quite different because 6 volt batts have greater Amp-Hour (AH) capacity than 12 volt. Typical 6v golf cart batts hold 200-220 AH while most 12v batts only hold 100-120 AH.
Using the 144V system in your example, here's the difference: (6 volt) 144 volts X 210 AH X 0.8 (max discharge) X 0.57 (correction for Peukert effect) = 13,789 useable watt hours (12 volt) 144 volts X 110 AH X 0.8 (max discharge) X 0.57 (correction for Peukert effect) = 7223 useable watt hours If we assume you'd use 350 Watt Hrs per mile (varies depending on the vehicle) you'd get about 39 miles range with the 6 volt batts and only 21 miles range with the 12 volt batts. Another crucial factor is that 12 Volt batts (no matter what the salesmen tell you) just are not up to the task of an EV. They will die on you quickly. I tried two different sets and both only lasted about 9 months. btw - you could also consider 8 volt golf cart batteries (that's what I did) which would hold 150-180 AH. They are sort of a compromise between the two and would get you range somewhere in the middle. They wouldn't last quite as long as the 6 volts, but mean less weight to carry around. Also my 8v batts have gone about 2 years now and are just about ready to be replaced. I'm told that 6 volt batts typically go 3 1/2 to 4 years. - Peter Flipsen Jr On Wed, Oct 2, 2013 at 7:33 AM, Sam Shepherd <[email protected]> wrote: > In the same auto what would be the difference in range between 6 volt and > 12 voltlead acid? > Like 24 6 volt next to 12 12 volt? > -------------- next part -------------- > An HTML attachment was scrubbed... > URL: < > http://lists.evdl.org/private.cgi/ev-evdl.org/attachments/20131002/2e8ad7be/attachment.htm > > > _______________________________________________ > UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub > http://lists.evdl.org/listinfo.cgi/ev-evdl.org > For EV drag racing discussion, please use NEDRA ( > http://groups.yahoo.com/group/NEDRA) > > -------------- next part -------------- An HTML attachment was scrubbed...
