Circuit Diagram of TP4056 LiPo Battery Charger For RC Toys

Robotronicdiagram. - Maybe you know that LiPo (Lithium Polymer) battery is the battery that has taken the electric RC gizmos world by storm,especially for Radio-Controlled (RC) toys like electric helicopters, airplanes and boats. Usually this battery is a type of rechargeable battery that provides high energy storage to weight ratios in an eternal variety of shapes and sizes.

Charging LiPo cells/batteries is not an easy task. LiPo battery obviously have a very different characteristics from conventional rechargeable battery types. Therefore, charging them correctly with a charger specifically designed for lithium chemistry is critical to both the life span of the battery pack, and ofcourse your safety.So you need special electronic circuit diagram for this battery charger like in figure 1 below.

Component List
  1. IC TP4056
  2. Resistor (see diagram)
  3. Capacitor (see diagram)
  4. LED (see diagram)


Circuit diagram like in figure 1 above is Circuit Diagram of TP4056 LiPo Battery Charger For RC Toys. The main component from the diagram is IC TP4056. The TP4056 IC is a complete constant current/constant-voltage linear charger for single cell lithium-ion/Lithium Polymer (LiIon/LiPo) batteries. Its SOP-8 package and low external component count make the TP4056 ideally suited for portable applications.

Furthermore, the TP4056 can work within USB and wall adapter. Other features include current monitor,under voltage lockout, automatic recharge, and two status pin to indicate charge termination and the presence of an input voltage.
