BAT (Battery) Detector v1.0
Do you have a battery and wonder how much power left? Then try this Battery Detector. Simply connect your polymer lithium battery to the JST connector on the board, you can easily know the probable power percentage.
The battery detector is able to work when the input voltage range is 3 to 4.2 volt. With the 3 on-board JST sockets (1 x JST 1.0, 2 x JST 2.0), it can detect most batteries. If your battery has neither JST 1.0 nor JST 2.0 connectors, don’t worry, there are 2 battery soldering pads can adapt the connector to different battery types.
Once you connect a battery to this detector, the 4 on-board LEDs will indicate the remaining power by percentage range:
- 1 LED = 0 - 25%
- 2 LEDs = 26 - 50%
- 3 LEDs = 51 - 75%
- 4 LEDs = 76 - 100%
If you plug the connector in a wrong way, a fifth indication LED will light.
- Dimensions: 80mm x 100mm x 7.30mm
- Visual indication on remaining power of a battery
- Different JST sockets for different battery connectors
