-- 2 8xAA NiMh rechargeable batteries connected to the MoPi, no mains power
-- the battery packs drained and the power shut off
-- I removed one battery pack to put them on the charger (they were all between 1.11 - 1.14 volts)
-- I connected a 5V power supply to the RPi USB plug, powering on the RPi, leaving the 2nd battery pack attached
-- this morning (9 hours later), I arrived and went to place the batteries from the 2nd battery pack (which was left connected) into the charger. They were around 0.9 volts. One battery was showing 0.1-0.2 volts, much lower than the safe discharge.
I guess my point is:
-- is power still being drained from a battery pack while the RPi is plugged into mains? If so, shouldn't it still prevent draining the batteries past the safe discharge level?
