Re: (ET) batterys in my I-5



ET's usually aren't used 7 days a week like street EV's.
The pack in my first ET arrived 2 years old and out of
balance, with 1 especially weaker than the rest.  Yet I
used it that way 1-3 times a week, mowing, sweeping
or plowing, most of the year.  You ought to have enough
capacity for several acres of mowing, and unless used
daily or more, the pack will probably die of old age
before running out of cycles, even if you discharge to
80% or more.
