Lithium Ion (Li-Ion) batteries have become the dominant energy storage device and are widely used in various applications such as energy storage for electric vehicles, and electronic devices such as cell phones and laptops. This is because these batteries have several advantages such as high energy density, high power density, and long cycle life. In this research, the charging and discharging process was carried out on 8 Lithium-Ion batteries with a capacity of 1200mAh. the battery charging process takes 10 data samples from 2413 population data, while the battery discharging process takes 11 data samples from 2813 population data. Based on monitoring results, the voltage value increases when the charging process occurs during testing. The minimum average voltage value is 3.52V, after charging, the voltage increases to 4.16V. The maximum average voltage value is 3.75V, after discharging, the average voltage decreases by 2.99 V. Each battery cell has a different voltage value and battery capacity. The greater the battery voltage value, the greater the battery capacity value. © 2023 IEEE.
