Lithium lron has more cycle span and capacity, safety. So why AGM still recommended for RVs? thus I had read this article: https://blog.grepow....acid-batteries/

 

When i choose the battery for RV, should i consider the cold or hot temperature features?

the Choice between Flooded Lead acid, AGM, or LiFePo usually comes down to cost.

 

for similar AmpHour capacities

FLA = $$

AGM = $$$$

LiFePo = $$$$$$$$

 

any of the shortcomings of any type can be managed.

I would think that all features as well as cons for each should be considered. Just one thought could be if you spent a lot of time in freezing temps. How would you keep lithium batteries warm enough to take a charge. What would be the cost to do that.
I don’t think the only factor could or should be battery cost.
I currently have two 79ah LA batteries. Might be I could get by with just one 100ah Lithium battery. Which would reduce weight, providing additional storage, and currently live in a warm climate. So the change to one battery with longer cycles, sounds like a no brainer. I should be able to double the time between battery replacement.

LiFePO4 batteries outperform LA with two notable exceptions:

  1. cost per usable AH per years of useable life,
  2. difficulty of charging in below freezing temperatures.

The second one is a deal killer for me.

Besides price; Compatibility with your truck battery if charging the camper battery while driving can be an issue. Lead acid can also be a problem if it is in a non ventilated compartment.
