I believe the Good to Know app says that, if you are not going to use the car for a long period of time, you should keep the 12v battery connected to a 'battery tender' and keep the car plugged into the EVSE.first question: in this situation should I attach a trickle charger (designed for a lithium battery) to my 12 volt battery?
second question: if I leave the main battery charged at say 85% will it survive the 6 months without draining itself?
The battery tender I have at home just for this purpose is a 'Noco Genius battery maintainer'. I haven't used it yet since I haven't made any multi week trips since Covid. But I plan to.
