Brief description: Make a simple and practical lithium battery charger. Changing the 4 ohm resistor in the picture can change the charging current. D1 is the power indicator, and D2 is the charging indicator and current limiter. Simple and practical lithium battery charger Make a simple and practical lithium battery charger
by changing the 4 ohm resistor in the picture to change the charging current. D1 is the power indicator, and D2 is the charging indicator and current limiter. During debugging, replace the 6.8K resistor with a 10K trimmer resistor. Use a digital meter to monitor the battery voltage when it reaches 4.2V. Adjust the 10K trimmer resistor to
