External battery for Puck.js?

You can power Puck.js from an external battery - either from the 0.1"/2mm pins on the board (3v and GND) or by using a 'fake' CR2032.

However there is no voltage regulator so your voltage should be between 2v and 3.6v. That means you can't directly connect a LiPo.

You can however:

• Connect a LiPo via a diode to drop the voltage
  
• Connect to 2xAA or AAA batteries
  
• Connect to a non-rechargeable lithium battery
  
• Connect to a LiFePo4 battery
  
  

Hope that helps!
