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

AliExpress listing
Board
SMA female connectors X6
6mm standoffs X4
M2.5 screw X4 (for standoffs)
49 pin machine contact array (7x7)
(2) 0805 49r9 calibration resistance
- 1 spare)
- Installed 49.9 ohm resistor on upper left SMA
- Installed 0 ohm resistor on upper right SMA (not in kit)
