Question around Pi and the 12v Power supply

[JacoG]

I have 3 batteries in parallel, do I just connect the 12v power supply to the terminals of one battery?

Yes but before you do that put a dc fuse(1~2A) in series with the pos lead cut the lead and put the fuse inbetween the cut wires.

Thank you Talia, I was worried about just connecting straight to the battery, where did you buy that fuse Holder?

Don't know which province you situated but when i was still in Gauteng there is quite a few electrical outlets that sold them Bright Lighting is one of them they have the dc fuses as well.

If you are in the East Rand you can try GT Electronics in Boksburg as well

Mmmm so I didnt do this, I just connected as is to each terminal...bad thing if its not connected via a fuse like this?

As the saying goes what can go wrong could go wrong. The chances are good the Pi will have an internal fuse don't really know as i haven't opened one up yet, but with batteries that can supply high currents in the event of short curcuits it is just good practice to install an external fuse.

Update: I ordered one from SA yesterday and to my surprise it arrived today and there is already a fuse attached.
