Request[edit]

Index Word	Description
0	Header code [0x00040000]

Returns a number which can be used to calculate the voltage using Vref * (value / 256) where Vref seems to be 5.0v.

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 (~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)

-Returns a number which can be used to calculate the voltage using this formula: <code>magic * (voltage / 256)</code> where <code>magic</code> is a constant number which seems to range somewhere between <code>4.6</code> and <code>5.0</code>. Based on calculations and battery behavior it seems like it's indeed <code>5.0</code>.
