Also, I believe it is a power window motor, not a wiper motor. But it is
definitely designed for 12 volts. It is usually run on 18. I have run
it on 12 and 24 -- it's a wee bit slow on 12, and a wee bit fast on 24.

A good idea!
It would also help to ditch the GE charger and use an individual charger
for each battery, or at least for every two (12v chargers). Hmmm, this
last only works if you connect the lift at 12 or 24 volts.
I am running my ET with six 12v gel batteries connected in series-
