Set up Adjust the trimmer to get a 12 Volt direct current input across the charging terminals. Connect the trimmer and the 47k resistor. Allow constant recent influx of around 0.5C to flow through the cell. A Li-ion Battery Charger Using LM317 As The Controller IC Primarily, an LM317 helps to supply a constant and steady voltage to the output.
Simple LM358 OPAMP based USB Liion charger Circuits DIY
Circuit Diagram. The the following figure shows the Li-Ion charger circuit diagram. Lithium-Ion battery charger circuit diagram (click to enlarge) The above schematic, the 19.5 V of the power supply are stepped-down to 5 V by the 7805 voltage regulator U1. The 5 V is used for powering the Arduino board.
Current Controlled LiIon Battery Charger Circuit
Step 1: Disconnect the battery to be charged. Step 2: Connect the DC power supply to the input. Step 3: Adjust the variable resistor till you get full charge voltage at the output terminal. (For 3.7V Li-ion output voltage will be 4.2V but here we will set it to 4.1V to increase the battery life).
Liion battery charger circuit (source ref. [21]). Download Scientific Diagram
During discharge of a Li-ion battery, ions move from the negative electrode through an electrolyte to the positive electrode, causing electrons to move in the opposite direction around the circuit to power the load. Once the ions in the negative electrode are used up, current stops flowing.

Here is a tried and tested sample circuit of a Li-Ion battery charger that can be used to charge any 3.7V Li-Ion battery using a 5VDC (USB, Solar Panel…) power supply. At the heart of the circuit is one microchip MCP73831, available in SOT-23-5 package.
Schematic Diy 18650 Battery Charger
This lithium ion battery charger circuit is very similar to the previous, with two differences. First, instead of just using the MOSFET, you also pass the input supply to the load through a diode. By connecting the FET gate to the input power supply and a diode (normally a Schottky) in series, the system load takes power from the input supply.
Battery Charger Circuits
The battery charger circuit is designed around a dedicated lithium-ion battery charger TP4056 IC. TP4056 is a complete constant-current/constant-voltage linear charger for single-cell Lithium-ion batteries. Its SOP package and low external component count make the TP4056 ideally suited for portable applications.
