Independant power

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.

The ones I googled are only 1.2 amp hours? https://www.ebay.com/itm/Mercedes-Be...-/282360817166

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

Cheers

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.

Iíve used two 20 Ah golf buggy batteries for over ten years, use a triple charger and they seem to last for ever.
Highly recommended.

I use a 36AH battery made from 36 x 18650 used laptop lithium batteries. But then I'm weird.
