Melting the cases is not a fire. And every melted agm case is due to incorrect charging mechanisms.
But there have been some cases on this site of catastrophic lithium failures.
I am starting to see people asking about fires and lithium.
These batteries are in the house. Not my design and not an easy fix to move them.
Thanks again

I had the exact same thing happen(even down to the crowbar) with the only set of full river 400 6's I've ever installed. I personally lean away from agm though we've had pretty good luck with the Outback and Northstar PLR platform over the year..
The only thermal runaway event I've ever seen, was with AGM in an
over insulated battery box. Got so hot that the cases fused to
each other, and we had to pry the batteries apart with a crow
bar. She wants ZERO risk of fire? She needs to live in a
concrete bunker with no electricity at all. Every electrical
connection, every outlet, every appliance has a risk of fire.
Period.

I hate to be the one to say it but LFP has arguably less
fire risk than agm. A short circuit in an agm could be
disastrous and AGM is not necessarily any safer or less prone
to thermal runaway events than modern LFP. I'd recommend a
cobalt free LFP like homegrid, simpliphi, or midnite if it
were me..
Thanks for the input.
I didn’t know that trojan was sold, and from
what you say, yeah scratch them off.
It’s currently at 30kwh. And thats probably a
good size.
As always, cost and time is a factor.
I’ll check the others out.
