Hello,
I'm aware that the 383L+ uses 2.5A of current but obviously this will vary. Have anyone measured the power consumption (and therefore current use) during various stages of use?
i.e. During cooling, when already at your chosen set point, when imaging, etc. I'm sure it won't use 2.5A 100% of the time it's powered up.
I only ask because I'm using a Skywatcher 17Ah Power Tank and I know my Skywatcher NEQ6 Pro mount consumes 2A of current during full-speed slewing (not often). I'm weary about 17Ah disappointing me on a night's imaging use. Mind you, I only power my mount and the 383L+ from the power tank. I'm not too keen on getting a 30kg Marine Deep Cycle battery, though it may end up being the only formidable solution.
