Modular Music Box – Powering Arduinos

While for testing purposes the Polymer Lithium Ion Battery – 2000mAh sku: PRT-08483 and LiPoly Charger – Single Cell 3.7-7V Input sku: PRT-00726 may do… further reading of Comments and datasheets suggests they may not be a final choice.

Cons

  • ~6hrs charging a 2000mAh battery at 280mA max
  • JST connectors can be *extremely* difficult to remove!

Pros:

  • Battery includes built-in protection against over voltage, over current, and minimum voltage.
  • useful 3 connectors – one to battery, one to circuit, third for 5V that powers the charger – so can charge the battery and power device at the same time.
  • through holes in the PCB for remote LED

So looks like we’ll need something more like:

which seems a bit expensive all in… particularly since we’ll require two battery packs – one in use and one on charge… (more…)
