Product Description
Lithium batteries can’t be charged as regular batteries or devices. Instead, you’ll need a li-ion charger such as this one. 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, and two status LEDs.
Product usage tips:
The red LED glowing means the battery is charging. The green LED glowing means battery is charged. Easy embedding into a project with the four mounting holes on the board. Comes with 5 pins that need to be soldered.
Note: This charger has no protection against reverse polarity, short-circuit, too high or too low voltage. If you’re looking for a charger with a protector, click here.

Excellent, compact, charging current adjustable by replacing the resistor. Ordered 10 pieces without problems.
Is it possible to charge 2 batteries at the same time on that charger?
