- This is a Lithium-Ion Charger, it can charge either 1 cell (default), or 2 cells in series (aka 2S), depending on a solder jumper.
- The board comes configured for single-cell charging, to change to 2 cell in series close the “SET” jumper with a blob of solder as shown in the picture.
- Recommended Input Voltage: 12v, Max 15v
- Based around the TP5100 Charge Controller IC, google for datasheet (in Chinese).
- Do not connect the battery backwards or all the magic smoke will escape.
