Please stop spreading some FUD here, there's reputable lifepo4
systems that have inbuilt fire suppression. Yes there's a lot of cheap
stuff out there, but if you are not buying directly you are in good
shape with the right UL etc markings.
Look at something like what they use in a solar setup, you can
purchase a 14.3kW battery + inverter for ~7500 and just wire a L6-30
for your PDU as appropriate.
Look at the EG4 for an example:

And the battery has inbuilt fire suppression system:

Most things can catch on fire, sure.. but not everything lacks any
safety systems.
Either way, this is fairly plug and play, and you can get two for 1+1
setup with options to have it control generator or other power input
(eg: solar) including controls to test generators etc or to charge
battery if you live in an area like me where we have some of the lowest
grid reliability in north america.
