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.
