How critical they are

Hi,

Li Ion cell operating window



Cycle life and temperature

"...Although investigation has shown that some Lithium fires are due to internal short circuits as described above, many, if not most fires are caused by abuse by the user. This may be "deliberate or negligent" abuse such as overcharging or operating in a high temperature environment"

So, why they are wonderful for a new design? They "seduce". The performance is because they are "tuned".

If dangerous (critical) in airliners (air conditioned)... I prefer not think they working in GA.
