I hear this a lot, and I have no doubt that the combination terminals that
golf cars often use are not the optimum. However, I have never had
problems
with these terminals, either on the ET or on a road EV with a current
limit of
anywhere from 250 to 400 amps. I use ordinary split washers combined with
flat washers - not even Bellville washers - and just apply a wrench
(gently)
every few months.
So far, the only battery connection I ever had fail was the cruddy generic
bolt-on clamp terminal that I used "temporarily" (uh, yeah, that's it ;-)
on
my Comuta-Car.
If you are running a 700 or 1000 amp controller, no question about it -
you
need the absolute best connection possible. But at the currents the ET
requires, it's not such a big deal, IMO. Use good stuff, but don't spend
your
entire allowance on high-priced lugs or clamps.
