LifePO4 chemistry is not prone to thermal runaway. It's simply not a concern.
They are fine to use in place of lead acid batteries, they will only be able to charge to about 90-95% of capacity with a lead acid charging profile. That same profile will also not take advantage of how quickly lithium can charge. The biggest downside will be the BMS- on smaller capacity lithium batteries the BMS is usually pretty weak and limited to 10a-20a discharge rates, which is not much when converted to AC. Lead acid are much better at higher discharge rates, but have a much lower capacity.
As far as this battery, yes it is larger (x2) and heavier (x1.5) than a standard lead acid deep cycle, but it has about 5 times the usable capacity, will last 3-4 times as long and recharges much faster. It's a much better use of limited space... But again for high drain applications, lead acid is usually better.
Community Reviews
This 12V 280Ah LiFePO4 battery is being used for off-grid backup power, solar setups, and inverter-based loads, where its big appeal is the large usable capacity for the size. It can run small appliances, lights, routers, and even a small air conditioner for hours, and the Bluetooth version adds monitoring that was missing on earlier units. The battery is heavy and much larger than a standard car battery, so it needs an inverter, proper wiring, and fusing. A few reports also raise concerns about slow transfer timing, lead-acid charger compatibility, and occasional bulging units.
The battery can support off-grid setups when paired with a sine inverter and appropriate safety wiring and fusing.
The automatic transfer feature can work well for protecting sensitive electronics when cutover speed is managed with an inline UPS.
The LiFePO4 chemistry can reduce thermal runaway concerns compared with other battery chemistries.
The battery can run practical loads like an EcoFlow Delta 2 through a 2000W sine inverter with less day-to-day hassle.
The automatic transfer feature can be relatively slow at about 30ms cutover, which may be too long for some equipment.
Charging from a UPS designed for lead-acid behavior can cause compatibility issues because the LiFePO4 BMS may not handle lead-acid pulsing and desulfation cycles well.
A non-Bluetooth version can deliver only about 2800Wh when used with an inverter at 90% efficiency, which can feel underwhelming.
Some units can arrive bulging as sealed batteries, and support may be poor based on returns and waiting for a replacement.

If you really want to use it, you'll need a ton of stuff to do it safely: inverter, high quality heavy gauge copper wire sized for the maximum draw of your inverter, a fuse or other overload protection device sized the same, etc...
I built a DIY solar setup using batteries like this. It was fun, and I enjoy using it. In 15 years I might even break even on what I paid for it. =)
I do plan on loading this up into my truck and wire the lights up to it and run a solar charger so I can run lights all night for fishing and not worry about draining the truck battery. Not sure how the 280ah is going to effect it but i'm sure it's more than enough.
