Finally got the van. Planning to have it built out as camper -- I'm not a DIY-type.
Planning on Lithium house. Live where it gets below 0 degrees F often (already 32 in morning), and planning to keep the van on my driveway.
I have read about lithium issues in the cold.
Here's what I am thinking:
Bring lithiums in the house for winter -- just use van as daily driver (have engine block heater).
If I do want to use as camper in winter, put lithium back in (already warm from the house) and go.
While camping, winter or otherwise, the lithiums should stay warm as they are inside the van -- kept reasonably warm for us humans.
Possible hitch: We decide to stay in a motel for a night on route to warmer climes, but motel parking lot goes to 0 degrees F.
Maybe shut down any draw on lithiums overnight, and don't return draw until camper is warmed up in the morning -- I suppose monitoring battery temp.
Let me know if am on a right track as an end user.
