I have a 240v/50A NEMA receptacle put in the garage, and am planning to pick up the Tesla mobile connector in anticipation of taking delivery of MYLR next week. The VIN number indicates Lithion Ion batteries, which I'm reading should only charge to 80% in order to maximize battery life. Since I'm not going for the wall charger at the moment, will I be able to monitor and limit charging to 80% by using a "dumb" (ie non-wifi connected) mobile connector charger?
