Well tomorrow we can maybe start to look at the example of the actual
stuff we are using.
Since you told me about the previous attempt at putting things between
the battery and the GSM stuff, I didn't fail to share some of your
concerns. But I didn't really understand the exact failure mode of the
last try, we can talk about it tomorrow.
It would be interesting to characterize the peak current on the Vbat
rail on the current design and maybe simulate VB_SYS there and observe
the reaction at this dangerous temperature.
