Those are Questar's problems. I have a Q3.5 and a Q7 with PG 1's installed and have never encountered them. The main problem is for the user--switching the battery in the scope's base when the old one goes dead. Removing the little Q from its tripod is no big deal but rather inconvenient. But removing the 50-lb Q7 from its base is a major operation even during daylight when I'm feeling fresh and strong--doing it late at night in the dark when one is not as alert is a potential recipe for disaster; if the Q7's battery goes dead early in the evening, I may resort to the slow motions, but later on it's easier to just quit for the night.
Does the PG-1 in the Q7 have a 12V input? Then you could carry a jump-start battery and appropriate cord, plug it into the base, and carry on observing.
It does but I don't use it. My luck with jump-start batteries has been dismal, and it goes counter to Questar's concept of the "self-contained observatory". I would run it off the car, except I have a foreign car whose cigarette lighter port doesn't work when the car's not running, plus it's rare to have the car next to me.
