Returns the battery voltage in an unknown format.
Returns a number which can be used to calculate the voltage using <code>Vref * (value / 256)</code> where <code>Vref</code> seems to be <code>5.0v</code>.




When the charger is plugged into a fully charged unit, this value will be maximum 0xD1
When the charger is plugged into a fully charged old3DS, the value will be around 0xD1 (~4.1v)


Unplugging the charger will make the value go down to 0xCE
Unplugging the charger will make the value go down to 0xCE (~4v)
 
The voltage at 5% battery percentage just after the LEDs start flashing is 0xAF (~3.4v)
 
Plugging in the charger at this point will make the voltage go up to 0xB9 (~3.6v)
