Fire safe battery boxes

[Bobiam]

What do you guys think about using fire resistant boxes (aka Lipo boxes) for battery charging and storage? Lipo batts are much more hazardous and not often seen for e-bikes, but any Lithium Ion batt can be hazardous under certain conditions. These boxes that cost very little appear to be a reasonable safeguard for charging batts in the home. Opinions???? Experience???

Most are worthless. Truly protective bags are very expensive. Get a surplus ammo box. Remove the waterproof gasket and latch the lid. Drill a hole big enough to thread the charger wire through. Line the hole with a rubber grommet.
