What you're doing is working. Trojan and USBattery, along with many others are available. Don't try to save five bucks buying a much cheaper quality import battery. FLA will do you fine, as with most boaters. In my working as a electrical engineer with submarines the worst fire I saw was a total lost $880mil ASDS. It was a battery fire and it wasn't a FLA.

Lipo is a completely different chemistry than Lfp ( lifepo4) of lifeYpo4) .

That is the sad part. Lithium other-chemistry are not differentiated from Lithium iron chemistry. The more dangerous are used for the little bit of extra energy. Then with a problem, all lithium chemistries are held at fault.

Yes.

Which is why it's important to shun the use of over-general "lithium ion"

and insist on identifying specifically LFP, NMC, LiPo etc
