Adding a battery

• My unit did not come with a battery
• Added an SMT mount ST connector to the board
• Added an 850 mAh LiPo battery
• The pinout on the card was backwards from the pinout of the connector at the end of the battery wires
  • Removed the pins from the battery wire connector and flipped the pins
• Charging works
• Battery is a bit too thick to screw the back on completely
• Switched to longer standoffs
• Someone else's page (they added an inline connector and wired to the card)
  • Adding a battery
