<![CDATA[Swollen M5Stack Battery.]]>Hello,
On one of my M5Stack devices the battery in the bottom module is swollen. That worries me!
I have used the M5Stack with the additional battery module. Then both batteries are connected in parallel, right?
Can that be the cause? Has anyone ever observed this when using the extra battery module?

I suggest you to keep it away from house.
This happens to them due damage, overheat, overcharge and other usage with impropriate conditions.

I recall in the past they had issues with one of their battery vendors.

You need to immediately put that in a strong metal tin incase it ruptures.
