Lithium 12v LifePo4?

I understand people recommend Lto batteries over the LifePo4 batteries, but I saw a video of someone running a high powered setup on LifePo4 batteries and it seemed to be holding voltage better than agm. I was thinking about getting some over Lto because they are cheaper? Is this a bad idea for 8k to 10k watts with a 370 amp alt?

Lifepo4 is more practical than lto for most applications. Most people on this site are parrots.

Why is agm better than flooded for car audio?

I see Limitless has some LifePo4, but they are way more expensive than the other LifePo4 batteries I'm looking at. I'm talking about the same 12v batteries people use for solar.

Be careful with the lithium solar batteries. Most of them have a BMS that limits their output amperage. I looked at one that was 31 series size, and it would disconnect the battery at 100 amps continuous or 150 amps peak.

It comes down to time vs money. You'll get more for your money by building your own lithium bank. If you prefer convenience and a warranty, then get a preassembled battery. My hp40 has been great, but if i could go back I would build my own.
