<div dir="ltr">I saw the results of a laptop battery catching fire while the laptop was in use. It was connected to a home-brew 3D printer. I can't image the fault that caused it but the aftermath in stink and smoke was awful.

<div>I’ve used LiPos quite a bit with RC planes and copters, I still have few
bats and two chargers. I have two LiPo protection bags that I regularly
used whenever transporting the batteries. I also use metal ammo cases to
both charge and transport LiPos. There has never been an incident here
regarding LiPos, but I’m not willing to burn down my house on a chance.</div>

<div>The biggest thing is to watch the batteries, and if they start to puff up
significantly, store them in a safe container until you can get rid of them
safely.</div>

If I do everything correctly when charging will this type of battery still have
