(ET) battery cost

["Christopher Meier" <mr23 mn rr com>]

I switched an E16 over to 3 12v Hawker SBS60's.  Runs well,
has enough energy for my (spring/summer/fall) needs.  I used it
for the first time last week to mow and sweep the grass.  Then
my kids and I dropped the attachments, and raced the much
lighter vehicle around the yard.  Boy the steering lightens up
with no battery weight in front.  Feels like power steering in
a '70's GM-mobile, drive it with a pinkie.  Bought the SBS's
(new, recent date code) surplus for $27/each plus shipping.
