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..

I was going to try and steer her towards lithium but she wants
zero, absolutely zero chance of fire, so no lithium.

HI Willam
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.
