okay thanks. If I cancel my renogy order I could go with a different brand without the self heating function (I can’t afford the other brands with this function) and keep them in the cargo area or get AGMs and be able to keep them in the cab space. If you feel like it, can you explain why you have a negative opinion of the renogy batteries? Just general low quality?
There is literally nothing that they sell that I would recommend. I have seen some of their stuff on vans that come into my shop with problems and sometimes it puts me one step away from a stroke.
Before I suggest alternatives for the batteries, tell us a bit more about your goals for power / solar / how often you will drive, will it be routinely plugged in / inverter power use, etc.
If you like, feel free to send a PM.
I am also not sure if you live in the PNW part of Canada or a place that gets really cold.

Consider to mock up a cardboard box the size of a few batteries like the size 27s and size 31XTs and see what will really fit in that location.
When I build electrical systems for customers, it is typically 2 batteries for a 1 kW type setup and 4 batteries for a 2 kW setup. Does not really matter if they are Lifeline AGMs or BB LiFe as they are both pretty close for continuous discharge capability.
