T7 vehicle battery trickle charge using the external

[Doug & Vanes]

Can the T7 be connected to an AC power source (in my garage) using the external power cable, for long periods while the vehicle is not in use? Are there any risks leaving the vehicle connected? In other words, will this power connection keep both the vehicle battery and auxiliary batteries charged?

I see no reason why you cannot do that BUT the EV battery should only be charged to and maintained at 50% capacity, as stated in the Handbook.
You could also use a plug in timer so the Charger only switches on for 4 hrs a day.
