Capacity tester for 4 Li-ion batteries

The capacity tester for 4 Li-ion batteries is a circuit with which we check the capacity of lithium batteries that we have recycled from the power supply that we use as an energy source in portable tools and computers. By checking their capacity, we can replace faulty batteries and thus extend the time of using the device’s power supply. Based on the test, we can separate those that can be used to power less energy-demanding devices. Defective batteries are then disposed of.
