No, not joking.

If you are worried about it, why not take an old lipo and throw it in the water?
Just spend the 4 $ or so for a test.

When I charge liion and lipo I always have safety procedures in place,
basically it is 2 to 3 meters from the door to the tiled terras, and I have HUGE pliers to grab a burning
one and put it outside, and a hose to stop any collateral fires it may have caused.

But some _advice_
IF you are so WORRIED why not use Lifepo4?
I have some lifepo4 cells in AAA form (about 3V per cell, in one keyboard, and in my temperature meter),
and those are safe, and have hardly any self discharge.
Lifpo4 high power is used in ships, and if you type lifepo4 in the ebay search window you find many variants and sellers.
It is MUCH safer than lipo or liion.
