Very Inexpensive Battery Maintenance Charger
1.0 ampere output. 13.8 volts regulated charge limit. This unit is good for 100 amp hours worth of batteries. IMO the voltage is a tad high for a high antimony RV battery with temps 60F or higher but ...

I am one of those whose batteries see widely ranging temperatures. So I'm about to install a digital temperature meter to my bank. But it's just one of those basic wire-with-a-probe-on-the-end thingys that gets attached to a battery post. And I can't help but fret over how (in)accurate it may be at displaying the actual temp of the batteries. The way I see it, on a cold windy day, the open-to-the-outdoors cabinet will cause the probe to read the ambient temperature of the cabinet, more than it will the batteries themselves. Likewise for very warm, calm days.
To at least help control the cabinet temps, I've considered partially blocking the large vent, adding a small piece of insulation over the post where the meter is attached, and perhaps even adding some hot water radiant heat to the cabinet, for cold weather conditions. Likewise, I plan on installing fans to help power vent the cabinet in hot weather. But I can't help but wonder if any of that is going to give me a realistic reading of the batteries themselves?
