In this video we continue learning about some best practices for getting power from your main battery (discussed in the last video linked above), to your various pieces of astrophotography equipment. The goal is to simplify cable management and allow for only one power cable to run up to the scope at which point the power passes through a fuse-box and is the distributed to the different devices. I reccomend permanently mounting the fuse-box to the scope to make setting up the rig super simple.
We also discuss choosing the right wire size, fuse size, and how to easily add remote power control into the system with a relay controller similar to the one discussed in this video: • Arduino Relay Power Co...
In Part III of this series we are going to take a closer look at both my observatory and backyard setups and how I handle power management in those instances!
In a later series we are going to tackle the challenge of how to handle data management without running 10 USB cables to your telescope.

I'll just pick up on the disclaimer at the beginning. I understand why that had to be put up but don't get too worried about it if using 12 volt dc sources. Use a decent commercial charger to top your battery up and you are fairly safe. There is a very minimal risk of electrocution from the 12 volt voltage. What you do need to be aware of is that under short circuit fault conditions these batteries can deliver a LOT of current - many hundreds of amps in some cases. Normally the current draw is relatively low - a few amps per connected device - but if a short circuit happens then the wiring can quite easily turn into an electric fire and indeed melt. So, as shown in the video, it is essential that you include fusing of some form both for the individual items and also at the battery output. Either with a standard car type fuse - readily available along with the holders or for a more sophisticated set up use a miniature circuit breaker - these are resettable and may help get you back up and running more quickly once the fault has been dealt with. Take a torch with you! BobUK.

Totally agree with this, I had a solar charge controller fail, and it basically dumped the battery and melted all the wiring, fortunately I happened to see the smoke starting and managed to kill the system before a fire started. (This was on a DIY swimming pool solar thermal heating setup)
