Just got the battery flashing from my Cuboid. Measured at 3.38 V on my doohikey. Tesiyi batteries.The brown turds can safely be discharged to 2.5v to get the full 3000mah.
I suspect other batteries have a higher cutoff voltage and thus seem to give more power.
Can anybody tell us what the voltage of the batteries are when they come out of the Cuboid drained?
I suspect the Cuboid might have a standard cutoff voltage of perhaps 3.2volts.
