use in a RC model aircraft or a drone? The voltage varies with charge
from 4.2 v down to about 3.7 v
I think it should work since the Pi has a regulator that drops the 5v
supply voltage to 3.3 for internal use, but I don't know what minimum
voltage the internal regulator needs to work correctly.
FWIW, I'd prefer to avoid using a standard off-the-shelf 5v output power
- They're are rather bulkier than a bare LiPO and, if possible, I'd like
to get a Pi zero plus the battery into the space behind a Pimoroni
HyperPixel - 4.0, which is 86mm x 56.5mm
- Almost all power packs only have a single mini USB connection for both
charging and power output, so it would need a additional wiring and at
least an external socket plus plug to avoid the need to unplug it from
the Pi to charge it - adding more bulk and fiddling.
