I currently get a good 6 hours imaging out of my setup.
I can't connect both tanks together unfortunately. They're the Celestron power tanks. All closed. No access to the battery terminals. Later on I'm thinking of replacing them by one big Battery. Got a couple of friends who use 100Ah batteries on the field. They're not that big either. Just heavy.
Would you know how much the Gemini draws? I also saw in a post very recently that it's bad to run the motors on 12V DC. It should be closer to 14V DC. They overheat. Is this correct? I though it's all good as long as you correctly balance the load. Mine are the high torque motors and I never had any overheating problems to date.

Hi Marc,
Ah ok that is good that you do not steip up and then down.
The Gemini runs OK from 12volt to 18volt. Overheating is always a result of unbalance.
With a higher voltage you get a higher torque in the motors.
The Gemini draws about 3amp when you slew with both motors at the same time at maybe 1200x to 1400x.
At tracking I guess it does not draw more then 750mamp if I remember well when I measured it once.
Well about connecting in parallel the both tanks there is a way as you have an output on both but if you do not feel safe doing it ...
