FiiO Snowsky Retro Nano Extended Battery Case

Tired of FiiO's poor power management? Wish you could get a whole day out of your Snowsky Retro Nano? Well now you can and somewhat in style.

Fits a 963450 battery, but this can be altered with relative ease as I've included a STEP file.

WARNING - Be careful with lithium ion batteries. Battery fires are no joke. If you're not comfortable handling batteries, then please do not proceed with using this model.

Orientation

• Print the base with the exterior face down.

• Print the case with the top face down.

Assembly

• Make sure both the included 10440 battery and your new battery are fully charged.

• Carefully remove battery door from the FiiO Snowsky Retro Nano (you'll need a small, thin object to bend the retention clips out of their locating hole).

• Solder some thin terminal shims to the new battery wires.

• Securely wedge the shims between existing battery and contacts.

  • If you can't manage to do this securely or use shims, then solder the wires to the terminals.

• Insert Retro Nano and battery together carefully.

• Place base on bottom of the case.

Screw together with some M3 SHSC screws (M3x4 to M3x8 length).
