During my burn-in test of my GB Pi 2, I noticed a strange behavior with the PowerBoost 1000C -- the red low battery LED warning flashing after a few minutes of use.
I started with a fully charged battery with the multimeter reporting 4.18v and recorded the following:
- @4.18v - red LED is off
- @3.84v - red LED rapidly flashing intermittently
- @3.72v - red LED constantly lit
Spec sheet for the PB 1000C says low batt warning is triggered at 3.2v level but I'm seeing differently. This appears to be a known issue with the PB 1000C and being discussed over at Adafruit's forums.

Anyone else encounteres the same?
