The XT-60 Fuse(TM) Fuse
Everything important needs to have a fuse to protect from a catastrophic event. Sometimes you want to control the current especially if not using a BMS (i.e. a raw battery pack.) This little device is your "last ditch protection" for your power source. It inserts easily into existing systems allowing you to retrofit more protection for your equipment.
I had this manufactured exclusively for us and are very good quality. We include a 20A fuse with it but you can use up to 30A safely.
Finally, for the sake of clarity I would also offer that the two in-line fuse products, both the "The Ender 3 Fuse(TM)" and "The XT-60 Fuse(TM)" are exactly the same.
I wish everyone the best in these difficult times.
