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)
