Here's a link to a FB video showing what "could" happen when a LiPo experiences Thermal Run Away.... this one was intentionally OVER CHARGED to an extreme. What would this do in your charging area??
You'll have to CLICK on the tile below and watch it on FB (sorry).
The creator of the video I linked is trying to upload it to YT for our enjoyment. It's a Thermal Run Away on THERMAL camera... very dramatic to say the least
