Yes I guess that's right but I still plan to use the Rosenberger plug since I found a source that will sell them in Germany and have ordered 5 of them. The price of 20 euros plus 16% VAT is not too bad but shipping was a bit high which is why I order 5 and they are slowly making their way to the US. I just don't want to mess with the wiring or put any extra access holes in the frame or side covers. I suppose there are ways to do that without damaging things but I just think it's cleaner with the Rosenberger plug if it can be purchased. I see now that Luna Cycles in the US has discontinued ordering that connector so it's fortunate I found a source, Powerbutler in Germany, willing to sell and ship them to the US.If i am understanding right, you dont even need a Rosenberger connector. You can solder on two wires under the Rosenberger plug in the Focus harness and bring them out where you want. Then just plug your extended battery on.
If i right the System recognizes the range extender an drains it first. I see no reason why this will not work. I am planning to build a 10s5p Extension with Samsung 35e . Maybe a switch like on the tec pack is needed addionally. Greetz
