Battery Fires, why they happen.
Typically, LifePO4 (Lithium Iron Phosphate) batteries don't catch fire, but they do get hot internally with a lot of power being drawn off them. This heat, if not controlled can cause the battery cells to swell, and in worst cases, generate explosive gas that will explode.
World Wide, battary (LiFEPO4) explosions are EXTREMELY RARE.!
Basics:
All Batteries are dangerous, even the small flashlight cells can be.
The industry makeing the Lithium Iron Phosphate batteries is not under any control to warn people of this explosive gas danger. It's no surprise as the Lead Acid battery in your car has a history of explosive gas issues and there is no control over them either. Common sense is your best defense.
Don't drop or abuse your battery, this can cause an internal leak issue leading to a leak of toxic chemicals and in worst case, a gas explosion.
To date: June, 2026, only 4 explosive gas instances with LiFEPo4 batteries has occured world wide. (At least as far as I can find)
So the track record for these types of batteries is quite good, and much much better than your car battery which over the years has killed and injured quite a few.
What can you do ?
If you are very safety consious, you can put a ventilation system into your battery storage area to vent any dangerious gas out before an explosion can occur.You can ask me about how.
