Battery operation with fipy + pytrack
I'm trying to get a pytrack/fipy running on battery but it has trouble starting. Fine to keep it going once running but can't start when plugged in. It appears something is current limiting, Vin measures at 1.8 or so when battery is 3.9-4.2. Hitting reset doesn't help.
I've seen comments about using lipo's for their current capability, I am using a generic Li-ion 26650 which is certainly capable of multiple amps (haven't measured draw yet) so that seems unlikely. Any suggestions ?
Hardware schematics certainly would be useful to figure out what is going on.
Update: I've tried the same with my pysense board, it starts fine with the battery so likely some difference between pytrack and pysense, maybe the GPS module needs 5V to start ? (though datasheet for it indicates not, max 29 mA@3v3)
@niallp I am having the same issue. Did you find out what the problem was?
