Lithium Titanate
Hi All, I got a quote on Lithium Titanate "Max discharge rate is 10 C so 900 amps for 90 ah and 1200 amps for 120 ah The 120 will be 30% more expensive than the 90. Price for 90 ah is $150...

I’ve never heard of them, so I looked it up:

I’ll be sticking with LiFePo4’s because (per expion) they charge about 3x faster than flooded wet cell batteries which seems to strike a good balance between safety, density and charge rate - JMO

What does "3x faster mean"? 1/3 the time for restoring the same number of AH? 3 x the AH in the same time?
It takes about 2 1/2 hrs (150 min) to restore 184 AH doing a 50-90 on four 6s of 460AH with a 75 amp charger set to 14.8v, run from a 2200w gen (maxing out the gen for VA)--BTDT.
So if it means you can do that in 1/3 the time with LFP, that means in 150/3 = 50 minutes to do 184AH. So you would be charging at 221 amps for that 50 minutes. How can you do that in an RV?
At 1C, that would mean 221AH worth of LFP in the bank. At .5C that would be with 442AH of LFP.
You can carry the batteries, but howinheck can you charge at 221 amps with what size generator to run a 221 amp charger?
So what value to an RVer is the claim of "3 times faster" charging? How would you set up your RV to be able to charge "3 times faster"? I can't understand it.
