TP5000 Lithium Battery Charger Module 1A Li-ion Lipo LiFePo4 4.2V/3.6V

The TP5000 charging module functions similarly to the TP4056 but offers additional support for charging LiFePo4 (Lithium Iron Phosphate) batteries. To operate, simply connect a 5V power source to the input, and connect the battery to the B+ and B- output terminals. A red LED indicates charging, and once complete, the module stops charging and the LED turns green.

For 3.6V LiFePo4 batteries, desolder the F jumper pad. For regular lithium-ion or LiPo batteries, reconnect the F jumper.

Specifications

• PCB Size: 21.5 x 14.5 x 4.2 mm
• Input Voltage: DC 4.5-9V (recommended max. 7V)
• Output Voltage: DC 4.2V (default) or 3.6V
• Output Current: Max. 1A (adjustable)
• LED Indicator: Red for charging, green for fully charged
• Compatible Batteries: 4.2V lithium batteries and 3.6V LiFePo4 batteries

Switch Modes

• F jumper connected for 4.2V output (Lithium-ion/Lipo)
• F jumper disconnected for 3.6V output (LiFePo4)

Adjusting Output Current

• Change the resistor beneath the “SANYA” label to adjust current.
• Default setup: R100 resistor for 1A max output.
• Add an extra resistor for increased output (e.g., 1.5A with additional resistor, 2A with 0.1Ω resistor).
• For output above 1A, a heatsink is recommended.

Features

• Utilizes premium multilayer ceramic capacitors (X7R) for stability and safety.
• Copper strips support 5A large current in a compact, fully enclosed design for low interference.
• Efficient DC-DC buck mode for reduced heat and enhanced charging efficiency over linear chargers.
• 1A charging with only ~0.7A input current.
• Option to charge lithium-ion or lithium iron phosphate batteries with a jumper setting.
• Small form factor, with overheating protection that reduces current if overheated.

Advantages

• Switch buck mode for higher efficiency and less heat than linear circuits.
• 1A charging current, reducing charging time and improving thermal performance.
• Selectable for lithium-ion, lithium polymer, or lithium iron phosphate batteries.
