I have 3 Hawker SBS60's in my Elec-trak.  I never accurately tested them,
but expect they are about 52Ah or so new.  I run them for about 40 minutes
at a time, but that pulls them down to about 90% discharged when not used
often.  Not a big deal since the tractor is used at most 50 or so times a
year.

Lee Hart has I believe the same battery in his E16, but he used 6 of them,
a string of buddy pairs.  I haven't heard yet how those are working for 
him.

I have a few dozen cycles on mine, since last July.  At times I've wanted
more capacity, and will likely add 3 more.  This will still be lighter than
the
original pack.
