Why would Roger consider getting his PbSO4 wet-cells from: Costco,
Interstate, or GC2's with small 75Amp golf cart terminals?
If for his home solar or his e-tractor

small lead battery terminals for low power use should be OK.
I agree. His E-tractor isn't likely to pull high currents. Golf cart
terminals are designed to routinely handle 75 amps for extended periods.
That should be enough.
If for Roger's 96V EV conversion
http://www.evalbum.com/1313
using a Curtis 1221 controller, perhaps the terminals could get hot, but
that controller only draws 400 battery Amps (someone verify that).
A Curtis 1221 will only pull that 400 amps under special circumstances,
and only for a very short time. The current rating is motor amps; not
battery amps. Battery amps are (almost) always less. The only time it
would ever reach 400 battery amps is with a) a stone-cold controller, b)
at full throttle, and c) at exactly the right motor RPM so its back EMF
is the same as the pack voltage at that 400 amps. This condition is only
likely for a matter of seconds. The 75-amp golf cart terminals should
easily be able to handle that.
I'll assume Roger's EV cables that are set up for L posts are large and
robust. So getting enough metal to metal contact to keep from melting posts
is Roger's concern.
Yes. It's not that a good golf cart terminal can't handle the current.
It's that a *BAD* golf cart terminal cannot (dirty, loose, corroded,
assembled wrong, etc.)
