Auto Cutoff Lithium Ion Battery (3.7V) Charger Circuit Diagram ETechnoG

3.7V Charging Circuit Diagram. You are in the circuit we don't use any ic or zener diode. We use three 1n4007 diodes in series and a transistor to maintain the output current. In the above circuit, whole charging is driven by bc547 transistor and relay during charging the circuit takes input form charger circuit shown above.

In The Above Circuit, Whole Charging Is Driven By Bc547 Transistor And Relay During Charging The Circuit Takes Input Form Charger Circuit Shown Above.

~ as in abouve picture glowing green led because this battery is fully charged. Web once the auto cut voltage is set the circuit is ready to use. Web for a project, i need to charge a 3.7v lipo battery.

I Also Want To Protect It From Over‑Charging / Over‑Discharging.

The charging of the battery depends on the type of the battery. Now our circuit is completed and now we have to check this circuit. There are many types of batteries using different electrolyte materials.

The Datasheets Are Available Here:

Designed a circuit diagram from easy eda needed components : Then take a short wire and short circuit the output. Web 1cell lipo battery = 3.7v to 4.2v

Check The Output If Is 5V Or 12V And Let The Multimeter Connected At The Output So We Can See If The Votlage Will Drop.

Soldering iron lead past pcb holding stand demo. We use three 1n4007 diodes in series and a transistor to maintain the output current. Web description of 3.7v to 5v, 5.3v, and 6v converter circuit the complete circuit diagram, of the voltage converter circuit, is given in fig.1.
