Lithium Battery Charger/Discharge Module TP4057 (LX-LBC3) Type-C USB 1A

Lithium Battery Charger/Discharge Module TP4057 (LX-LBC3) Type-C USB 1A

With this small module with TP4057 integrated circuit, you can safely charge Lithium-Polymer and Lithium-Ion batteries. You can supply power at the input via a Type-C USB cable or via the + – terminals on the sides. The voltage riser on the module can provide a stable +5V without the need for an additional booster module.

Electrical characteristics:

• Model: LX-LBC3
• Charging chip: TP4057-1A
• Input voltage: 4.5 – 5.5 V
• Output voltage: 5V
• Charging current: 1 A (max), adjustable, select according to battery capacity (xxx mA*H/4)
• Battery charging voltage: 4.2 V
• Static discharge current: ~80uA
• Indicator LED: 1x discharge (blue), 1x charge (green)
• Note : There are contacts on the back of the module for external input.

Usage Method

• The module can be used by connecting the positive and negative electrodes of 3.7V lithium battery. The module itself has overshoot and over discharge protection, and the lithium battery can also be added with a protection board.
• Type-C port, solder hole and reserved input/output interface on the back are the same. The line is directly connected.

Matters Needing Attention

• Do not connect the battery in reverse, connect the reverse burning plate.
• Connect the charging head before connecting the battery, and test whether the charging lamp of the module displays normally.
• The wire should not be too thin. If the power supply current cannot keep up, the wire must be welded
• Batteries can be connected in parallel, not in series. Only 3.7V lithium battery, full of about 4.2V.
• This product is not intended to be a power bank. Its power is relatively small, with a maximum of 45 watts. And there is no charging protocol. It may cause problems in the use of some mobile phones, so when it is used to modify the power bank, our store will not be responsible for the use problems of some mobile phones.
