Actually I was comparing equal weight in 12V or 6V batteries not parallel
strings.

But in reply to getting less range with only 1/3 the batteries...well duh!
If you have 1/3 the weight in batteries of course you're only going to get
1/3 the range (perhaps a bit more).  I'll grant you though that you might
find a newbie silly enough to be surprised by that.

>That was my point, perhaps I wasn't very clear.

I went back and re-read your post.  I still get the impression from it that
you were implying that the high voltage pack accounted for the low DOD, not
the simple fact that you were carrying more weight in batteries.
