I’m putting together my first ebike build out of an old mountain bike. I’m assembling the battery pack from scratch using salvaged 21700 cells. I don’t imagine many people install fuses on their battery packs but given how violent these unprotected cells could be in the face of a short… I would sleep better at night if mine had one. Trouble is, I am having difficulty finding a suitable fuse. The vast majority of fuses I can locate online are automotive/marine/audio fuses usually maxing out at 32V. The pack I plan to build will be 14s lithium ion, and thus tops out at 58.8v. Has anyone else done a battery pack build with fuse? What fuse type/rating did you use? Where did you buy them? What brand?

Any info would be appreciated.

Thanks!!
