Hi David -

By fresh batteries, I mean a fully charged deep cycle.  Mine was about 6 years old, so I replaced it with an AGM deep cycle today.  It’s a 60 amp hour battery, which should be enough capacity for a 5 hour imaging session.

My original power box with a group 24 lead acid battery powered a cooled DSLR, an NEQ6, an Intel Compute Stick, Moonlite focuser, a powered USB hub, and a Surface Pro for about 5 hours.

I’m going to put an ammeter in-line on the power supply to the PMC-8 to see what the real time consumption is while slewing and tracking.

I’ll post my findings as well.

Unless you are doing photography, or are using a
large magnification, it should be fairly easy to
keep objects in the field of view even if the motors stop running.

Fresh batteries sound like an expensive long term
proposition. I am using a YUASA NP7-12 7.0 Ah
rechargable lead acid battery. I am also making
up a 12-19 volt convertor to keep my laptop
running from the same source. Time will tell
whether this has enough capacity for the job. Watch this space... :)
