.7 volt is with a meter. A new Sure-Power 70-2 or 160-3 at 50% of design I rating would typically show 1.2 - 1.4 volts drop across the junction. Going the KKK 1811-AA route was not much better. The Skottky device isolators had a ridiculously high percentage failure rate. Ralph Scheidler was a PhD in thermodynamics. He designed the heat sink radiation area meticulously for each device. Those fins are NOT THERE to dissipate a .7 volt junction drop.
Silicon device battery isolators went the way of rotary dial telephones thank god.
