12 volt outlet

I’ve not taken delivery of my new Rancher yet….

I will probably add a DIY 12 volt "cigar lighter" type outlet to my 2015 Rancher soon. I’ve added those to countless motorcycles, always connecting them directly to the battery, and adding an in-line fuse if one was not provided with the outlet. I’ve mounted the outlet itself to the handlebars or a convenient frame section. I like to have an outlet for my GPS, cell phone, air compressor, etc. I generally don’t add an inline fuse to keep things simple. I’ve been reading on this forum about several folks who have done something like what I plan, but they have not connected directly to the battery. I know Honda makes a plug-n-play outlet, but the cost is nuts when I can do my own for $10 (less actually, I have an outlet in my garage right now!)

If access to the battery very difficult on the Rancher? Is that why no one connects directly to it?

Thanks.
