Charge lithium-ion batteries easily with this Li-Ion Charger featuring CC/CV technology and built-in protection against short-circuits.

Lithium batteries are charged differently than regular batteries and devices. You'll need a li-ion charger like this one to charge them. Integrated with the CC/CV charging technology, it is the simplest way to charge a lithium-ion battery.

The board has a USB Type-C connector for power, a JST-type connector for batteries, the charging circuit, a protector, and two status LEDs. Comes with 7 pins that need to be soldered.

Product usage tips:

For older Li-ion charger with protection boards, connect the TEMP pin to GND to initiate charging. The red LED glowing means the battery is charging. Easy embedding into a project with the four mounting holes on the board.

Note: This charger has protection against short-circuit, too high, or too low voltage. It has no protection against reverse polarity.
