ACROBOTIC TP4056 Micro USB 5V 1A Lithium Battery Charger with DW01 Battery Protection IC


Regular price $9.99

Want to easily add a rechargeable battery to your electronic projects? Then the TP4056 charger IC paired with the DW01 battery protection IC in this module are for you! This tiny breakout board is perfect for charging single-cell 3.7V 1Ah—or higher LiPo cells such as 16550s—that don't have their own protection circuit.

The fantastic TP4056 charger IC (datasheet) and DW01 battery protection IC this module will offer 1A charge current then cut off when finished. Thanks to the protection IC, when the battery voltage drops below 2.4V the protection IC will switch the load off to protect the cell from running at too low of a voltage. In addition, this IC also protects against over-voltage and reverse polarity connection, usually destroying itself instead of the battery. Nonetheless, we cannot emphasize enough to please check you have it connected correctly the first time.

This breakout board makes it easy to add a rechargeable Lithium battery to your microcontroller board or single-board computer such as Arduino, ESP8266, BeagleBone or Raspberry Pi!
