@Kosha2905 Lithium cells are usually limited to 3.7v ideally, 4.1v would be the full charge limit.
The battery shield probably uses boost regulators that increase a lower voltage to a higher voltage, and it does this by drawing more mAmps and rapidly charging and discharing a regulator, you can get 9v out of a 1.5v AA battery, but it'll drain the battery very quickly.
Also, he was testing the voltage of the battery cell directly, not the voltage after being regulated.

4.13 v ? Is this because the battery is under load? Cause i thought the minimum voltage for the arduino is about 7v (well, 5 v, but 7v is the "safe" voltage according to the specs)
