MCIGICM 12 AWG Inline Fuse Holder with 30A ATC/ATO Blade Fuse, 5 Pack

I added a battery tender and a USB outlet to my motorcycle. Each one required a dedicated circuit from the battery (trying to tie into the factory fuse block would have been a nightmare).When adding a circuit, ALWAYS add a fuse as close to the battery as you can get it. If an unfused power wire accidentally grounds itself to the frame, the best you can hope for is that it will melt in half before it sets anything nearby on fire. I’m not willing to take that risk, especially when fuse holders are inexpensive.I bought these holders because they have a rubber cap that covers the fuse and fuse socket. Since these live under the seat of my bike (not normally hit by splashing water but not totally shielded either), it made sense to have everything covered.I soldered and heat-shrunk all the connections, then plugged a fuse in. Everything works fine. My battery tender is on one circuit, my USB outlet on another. I put a little dielectric grease on each fuse to add an extra layer of protection against corrosion, but that’s not necessary in most cases.It’s been about a year and both circuits are working correctly. I used a third one of these when I put an electric fuel pump on my lawn tractor, and that one also works fine. Not much to say about these except that they’re a good value and they work well.
