Paul's comment #4 in this thread:
https://forum.pjrc.com/threads/54054-Teensy-3-5-could-withstand-6-4V-Vin
...leads me to believe that it might be possible to run some, but not all, Teensy boards on a 2S LiFePO4 battery (5V-7.2V) without needing an additional voltage regulator. If I'm reading that comment and the linked schematics correctly (which I might well not be), it seems like it might be safe to run a Teensy 3.2 or 3.5 directly from that voltage on VIN, but not a Teensy LC, 3.0, 3.1, or 3.6.
Is that correct, or would an additional voltage regulator be required for a Teensy 3.2 or 3.5 powered by a 2S LiFePO4 battery?
FWIW, if it makes a difference, I'm planning on around 30mA of current draw from the 3.3V pin.
Thanks!
