runaway. This makes them a great substitute for
applications that might take more abuse than
you’d be comfortable with for regular Li-ion cells.
I prefer to use these for the added safety, albeit
at the cost of energy density. These are becoming
more common in solar harvesting applications
such as solar yard lights (usually 14500 or 18500
sized), solar power banks, boats, and RVs.
