Well - Søren wrote that it is rated for 2,5A, which is a lot of current and lot more than the Soekris requires. There must be a lot more current for the bead to blow that much. I generally think it is a very bad idea to run battery packs without a fuse in the wiring. And such a fuse for supplying a Soekris should maybe in the 1-2A range and not more. Adding fuses to battery packs is something noone should forget to add. This is for protecting the cable and not the Soekris, since you can't have a cable with the required gauge for sustaining a short ending in a barrelplug, so the cable must be protected. > Bob > > > On Nov 28, 2007, at 1:59 AM, Sean Murphy wrote: > > > Greetings all > > > > I have a net4801 that, unfortunately, was running connected to a large > > battery bank when a short occurred.
