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

The TP5000 charging module is a versatile charging solution, similar to the TP4056, but with the added capability of charging LiFePo4 (Lithium Iron Phosphate) batteries. To use, simply connect a 5V power source to the input, and the battery to the B+ and B- output terminals. The charging status is indicated by a red LED, which turns green once the charging process is completed.For charging 3.6V LiFePo4 batteries, the F jumper pad should be desoldered. For charging standard lithium-ion or LiPo batteries, the F jumper should be reconnected.

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

By changing the resistor beneath the “SANYA” label, the output current can be adjusted. The default setup includes an R100 resistor for a maximum output of 1A. Adding an extra resistor can increase the output (e.g., 1.5A with an additional resistor, 2A with a 0.1Ω resistor). For outputs above 1A, it is recommended to use a heatsink.

Features

• Uses high-quality multilayer ceramic capacitors (X7R) for stability and safety.
• Features copper strips that support a large current of 5A in a compact, fully enclosed design for minimal interference.
• Efficient DC-DC buck mode for less heat generation and improved charging efficiency compared to linear chargers.
• Provides 1A charging with only ~0.7A input current.
• Offers the flexibility to charge either lithium-ion or lithium iron phosphate batteries with a jumper setting.
• Compact design with overheating protection that reduces current if overheated.

Advantages

• Switch buck mode for higher efficiency and less heat generation compared to linear circuits.
• 1A charging current for reduced charging time and improved thermal performance.
• Selectable for lithium-ion, lithium polymer, or lithium iron phosphate batteries.
