Creative Muvo 2c battery case

thingiverse

Muvo 2c didn't have a good battery to start with and a new one costs more than the speaker itself. With this case you can replace it with a 18650 battery. You need to route the battery wires from the speaker through a drilled hole. The case is glued to the speaker to retain waterproofness. NOTE: you need to add some foam padding at the ends of the battery (see fig.). Also you may need to peel off plastic from the battery if it doesn't fit the cradle properly. IMPORTANT: When you peel off the rubber pads from the bottom of the speaker, you'll find a hole under one of them (see fig.). I'm assuming this is for equalizing atmospheric pressure. You need to cover it with a piece of sticky tape. I used super glue to attach the pads to the new case. NOTE 2: when you route the battery wires, note that the upper cradle part has a notch for the routing.
