I am new to this Forum but I have been working in PHEV and EV's for years. I just got a 2013 FFE. So far I have added a class 2 trailer hitch for my bike rake and a small trailer I take to hardware stores . I also had Linear Logic send me the prototype Scan Gauge board which was $25 plus shipping. Next I plan on adding extra battery power using the same method that SEFS used for the Chamdeo charger. I figure I can fit about 30kw in the trunk of Dow Kokum cells that I acquired from Oakland University in Rochester, MI. If successful, I will share the results. Shooting for 200 mile range!!!
