1S BT2.0 Voltage Meter

Since there were no affordable voltage meters for 1S BT2.0 lipos available on the market, I decided to create my own.

Parts you need to buy:

1x 0.28 Inch DC LED Digital Voltmeter (2 wire version) (e.g. https://www.aliexpress.com/item/1005003922909295.html)
1x Female BT2.0 plug (e.g. https://www.aliexpress.com/item/1005004465425088.html)

You also need a soldering iron, ~3cm of silicon wire (to connect plug to voltmeter), ~4cm of transparent heat shrink tube.

Instructions:

- Print the 3D part in the vertical position with support just for the "pin" (which will fit into the Voltmeter PCB hole)
- Solder the wires to the BT2 plug (you can rotate the bt2 pins so you can better route the wires to the bottom of the 3D part)
- Fit the plug inside the housing
- Attach 3D part with BT2 plug inside + wires to the voltmeter (slide pin into the PCB hole to lock part into place and prevent stressing the wires when you pull the lipo out of the BT2 plug)
- Solder the wires into the
