an excellent Lion charging circuit for you. The circuit load current is limited by resistor R2. For safety reasons, it is set to a maximum value of 500 mA. It is possible to increase the charging current by decreasing the value of the resistor. thanks for watching, don't forget to subscribe and like, you can download the circuit diagram from the link below.
A list of materials
1X LM317T
1XBC547
1XBC557
1XLED
1X 25V/470uF
1X 2.2R/2W resistor
2X1K resistor
1X 220R resistor
1X4.7R resistor
3X 1N4007
1X 10K Trimpot
today in this video I've shown how to make a precision li-ion charger circuit. The heart of this circuit is the tl431 regulator. You can easily adjust the current by changing the 47ohm resistor, decreasing the resistor value will increase the current. you can use any online tl431 calculator to get your desired voltage. Before connecting to the battery, please check the output voltage first.
Components required for this project:-
1.tl431 regulator
2. d882 transistor
3. 1k ohm resistor
4. 680 ohm resistor
5. 47 ohm resistor
6.leds
