IP2312 4.2V 3A Lithium Battery High Current Charging Circuit Single Cell Li-ion Lipo Type-C USB Input 4.35V Battery Battery 18650 You need to charge your batteries with the current they need.

Charging the battery with high current reduces the number of battery charging cycles.

If you do not know the battery charging current

levels of battery capacity such as 2/10 3/10 are normal charging current.

IP2312 integrated used 3A Lithium/Lipo battery charging circuit.

It has a Type C feed inlet socket.

There are 2 pads next to the USB socket for external voltage.

The status of the charge can be monitored with the charging resume and charging completed indicator LEDs.

The charging current is fabricated 3A.

The charging current can be adjusted to lower currents by changing with the resistors given below.

Charging voltage 4.2V rounds.

If desired, the charging voltage can be increased to 4.35V.

Batteries below 3V cannot be charged with high current.

Trickle is charged slowly with current.

After the battery voltage is increased above 3V, the high-current constant current continues to charge.

Completes charging when the battery is charged by monitoring the battery voltage.

Switches to constant voltage mode when the charging voltage is 4.2Va and the current is below 300mA.

Continues to charge or stops charging according to the battery voltage ( 4.15 V) at 4-minute intervals.

When it falls below 4.1V, battery charging starts again.
