May 15, 20242 yr I have 3 batteries in parallel, do I just connect the 12v power supply to the terminals of one battery? https://solar-assistant.io/shop/products/dc_usb_psu

May 15, 20242 yr Author 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. https://britelighting.co.za/products/in-line-fuse-holder Edited May 15, 20242 yr by TaliaB

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.
May 16, 20242 yr Author Update: I ordered one from SA yesterday and to my surprise it arrived today and there is already a fuse attached.
