Battery Box for storing lithium lipo4 batteries

Trying to find a fireproof box to store my lithium batteries.   Everything I see when I search is for RC cars, electric bikes and drones.   Has anyone found a box for boat batteries.   The reason I ask as I store the batteries in the house and I had a friend who had a garage fire in a kids electric car.  Thanks.

To be honest I haven't thought about it, but now you have me interested as to what is in the market. I have always purchased basic battery cases from Amazon or bass pro but they are just a thick plastic.
