Latest Project, 72V Precedent

[Revolution]

Kelly G, how are those 12 volt US batteries working out for you? My 72 volt club car has continental 12 volt batteries and they are only good for about 425-475 amps before the voltage sag gets to the danger zone.

I only realized the batteries limitations when I switched out the Alltrax AXE 72450 for the SPM72650.

So I am curious what your voltage drop is and the max amps you can get from the US batteries.

Thanks.... I'm afraid someone else is going to have to answer your question about Lithium batteries though. I have no experience with them.
