<p>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.

<div>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..</div>

Thanks for the input.<br>
I didn\u2019t know that trojan was sold, and from
what you say, yeah scratch them off. <br>
<br>
It\u2019s currently at 30kwh. And thats probably a
good size. <br>
As always, cost and time is a factor. <br>

I\u2019ll check the others out.<br>
