I want to add fuses to my portable battery packs from what I understand from reading other threads is that a .65A 60V raychem resettable fuse will work for my UA-5 that draws 450ma. I'll be wanting to put the fuses on 1000 and 1600mah RC battery packs, and also some 3000's in the future. If anyone has experience playing around with different fuses for UA-5 power it would be great to hear about it. From what I understand I just put the fuses on the positive battery pack wire?
