Paging Mr. Mundy. Alexander Mundy to the white courtesy phone please!
Sorry, working in the field all waking hours currently. I have not put one together "stock" nor is my OliveR "stock" so I can't give a true comparison. Also I kept the fuse link in OliveR which is the largest voltage drop in it aside from battery internal resistance. I can tell you that with the Rossum wire in place of the bolted together pieces and the Mundy magnets, Reo pin, and 10 gauge wire soldered in place of the brass threaded rod and nuts they are very very low resistance mods. Don't remember the number I got off the top of my head (it's in the beta discussion somewhere) but it might be days or weeks before I have time to look or measure again.
