AGM batteries and engine heat? Or heat tape?
So I have these 135aH Fiamm's for my new van build., and I am thinking about how to keep them warm. I was planning to mount them under the high-clearance van, alongside the frame, for ballast and ...

Thanks, everyone!
Best I can tell, my PD 9280 is not temperature compensated. But if I use it to charge 2 batteries @135aH, I am at around the 0.3C recommended for low temps. So that should be ok, yes?.
My concern is boondocking for, say, a week with nighttime temps in the 20s, without any driving.

I've been using AGM for about 20 years in my ice machine. My experience is that they are good (albeit a bit weaker) down to about 40 degrees, but once they get into the 30s they are nearly useless.
When I move camp to a place with warmer nights, it takes maybe 48 hours for my 45aH ice machine batteries to warm up, just from ambient temps. I'm concerned it may be a very long time for the bigger ones!
