Product Description
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:
The red LED glowing means the battery is charging. The green LED glowing means it finished 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.
