I need to replace my auxiliary AGM battery and am considering my options. The van accessories don't pull a lot of juice...the main use is for LED lights, marine pump for wash-off hose, and a PROPEX heater. I've gotten away with 100 AH easily in the past.

• I would be using the van for weekend / max weeklong trips primarily, year round, in the mountains.
• Sometimes in the dead of winter so COLD is definitely a concern for both availability and chargeability.
• I've got a solar trickle charger I can use to keep it topped off when not in use, but primary charging is through the vehicle electrical system.

Here is what AI tells me:

"The best auxiliary battery for van dwelling in Colorado is a Lithium Iron Phosphate (LiFePO4) battery with a built-in self-heating function and low-temperature charging protection. Standard lithium batteries suffer permanent damage if charged below 32°F, making self-heating units a winter essential in the Rockies"

My very-trustworthy neighbor has LiFePO4 in his popup camper and swears by it (but is using it primarily for summer trips)

I'm filling out an application for PL coverage (as an independent contractor, for the first time in 20 years of geo experience) and have a couple of questions about the questions:

Does your business provide any one of the following services: Architecture, engineering or Construction management, or on-site construction services?

I assume the answer to this is YES, that my work as a hydrogeologist (well installation oversight, groundwater flow analyses) constitutes engineering and/or construction management.

Does your business provide any one of the following: Construction, Installation, Maintenance, Treatment, Cleaning or Security?

I assume the answer is NO, that my work is not in the direct business of providing these services.

Any help appreciated!
