Hi everyone
I'm wondering what people use to power their EQ6 R pro when they don't have access to mains power? I'm thinking a battery box with a 105 amp deep cycle battery in it? What do you use?
A deep cycle battery is good - Gel is probably the technology to choose (excellent cycle life, supports deeper discharges before sulphation).
105Ah is overkill though unless you're going bush for a week.
Your EQ6R will draw about 1A tracking and 2A slewing. At 50% depth-of-discharge (when voltage drops to about 12.35v), that gives you around 50 hours continuous operation. At 75% depth-of discharge (when voltage drops to 12.0v) you'll have around 75 hours continuous operation.
The greater the depth of discharge, the shorter the battery life - a common recommendation is to keep it to 50% or less, but 70% is acceptable for irregular use.
You'll need to work out how often and for how long (between re-charges) you intend to use the battery.
Yes 105 Ah is overkill and weighing around 30Kg+ will not be easy to cart around. I never use mains converter for my mount - too many wires in wet grass. Always use a 45AH deep cycle battery that will last a couple of nights easy, then I just charge it up again.
Shirley I use a 12AH gel battery to power my AZEQ6, weight is maybe 5kg like a counterweight. No issues ruining it for a couple of nights. This, charger and a simple wiring harness made on the spot at Batteryworld cost of the order of $60-70.
The big question is whether you want to power other stuff such as dew heaters, camera or laptop which can be quite power/hungry.
A really stable battery is a Mercedes Benz auxiliary battery. Off the top of my head I can't remember how many aH they are but it will be plenty and in the aftermarket they can be had for about $120. Big bonus is they weigh next to nothing and are about the size of a can of baked beans.just don't go to the dealer to buy one, it will cost you 4x that.

Though expensive an alernative is fusion power LIFEPO4 batteries, expensive but light, around 3kg for 30 ah.

That is a memory save battery found in a lot of ML class and GL class Mercedes. The one I'm referring to is for the W211 chassis E class. The part number is A211 541 00 01 and they are 12Ah. I happened to have an old one at work to check.
