The new Artesky lithium battery allows you to power your products in the field for many hours of use without needing electricity and power supplies!
When you need to power your visual or astrophotography setup, you are forced to use a 220V power supply, your car's cigarette lighter socket or a large, heavy lead-acid battery ... Use an Artesky lithium battery instead!
This battery allows you to power your mount, drive chamber, camera, computer and more!
Light, transportable and very compact, it is an incredible tool to improve your exits and avoid the transport of large batteries and useless weights.
The lithium battery is inserted inside an anti-shock, anti-dust and water-resistant case, this to guarantee maximum safety for transport and use.
On the battery there is also a small LCD screen with on / off button that allows you to see the remaining capacity in Volt of the battery and the instantaneous consumption in Amperes!
The battery offers two 12V outputs (maximum current 20A / hour) so ideal for powering your mount, a computer, your driving room, etc ...

How can I calculate the average duration in hours of the Artesky lithium battery?
Nothing could be simpler!
We only need to consider the average consumptions of the most used instruments with which you can compare, once the sum of the average consumptions is made, divide the battery capacity by the sum of the average consumptions and you will get an average duration in hours.
Skywatcher EQ6-R / AZEQ6 frame average consumption: 1.5A / hour
Average recovery chamber consumption with Peltier cooling: 2.5-3A / hour
Average computer consumption (with a fully charged computer battery): 1.5-2A / hour
Average Discovery consumption (Mini PC for astrophotography): 0.75A / hour
Average electronic focuser consumption: 0.5A / hour
Average reflex camera consumption (with false battery connected to the lithium battery): 0.2-0.4A / hour
For example, if we have an EQ6-R mount (1.5A / hour) + a ZWO ASI071MCC camera (3A / hour) and a Mini PC Discovery (0.75A / hour), the total will be 5.25A / hour.
A 48A battery will last about 9 hours (48 / 5.25 = 9.14 hours)
