Hi, have installed 7kW podpoint home charger which pod point stated was compatible with my 2015 Nissan Leaf. I am just a bit concerned as I have noticed battery degradation (12 bar to 11 bar and irregularity of available mileage drop during the journey) only 3 weeks after I started to use this. I haven't been using the app just plugging the charger straight in. Be grateful if anyone could confirm that they are compatible? Is adjusting the charge voltage a thing if I sort out the app?
