The thing that got me to buy Li was when I learned how fast I could charge the lifepo4 , fast charging is a really big deal to me because since I'm able to charge the battery so fast I can get by with a single $850 100 ah battery but keep in mind I use a generator and some people don't like generators.
The single 100ah Lifepo4 gives me reliable power when boondocking because even if I ever did get low on soc I fire up my genset and battery charger and in a very short time I can get the soc up no matter what the weather conditions are like and even at night time
.
This system allows me to have a very simple system with hardly any wires or components at all and also no solar panels
Imo if your boondocking with a generator lifepo4 is definitely the way to go or you'll end up buying multiple lead acid batteries over the years and end up paying more then the li battery.
If i had access to shore power I'd probably stick with lead acids for economical reasons , charging them correctly and getting there full life span.
Solar panels and AGM or solar panels with li ?? I have no clue but it looks like Iternerant1 is showing us some good info.
I'd be curious if there is some sort of fast charge advantage when using solar panels and li????
The other features of the Li didn't impress me much.
Lighter weight ?? It's not like I'm going to carry them around , the vehicle would carry the weight, I prefer lighter weight but not if I have to pay for it.
Better performance when running high amp appliances??
That didn't impress me much because I don't believe in running high amp appliances from batteries, I use the genset for that and save my battery soc.
Another thing I just thought about is ,, personally I don't charge from alternator/Invertor/charger but if somebody does the fast charging from li may be a huge help on keeping fuel costs down .
