520			_aABSTRACT Due to the environmental damage and CO2 emissions of internal combustion engines, developments in vehicle technology have increased recently. In this context, electric vehicles are of great importance. Electric vehicles work with advanced battery technology. Batteries are a storage method that can store electrical energy as chemical energy and alternately convert chemical energy into electrical energy. The longevity of the batteries has made electric vehicles more popular. Although there are many types of batteries, Li-ion batteries are the most widely used. It is preferred more because of its high energy densities. Many studies and research are carried out to make these batteries work longer and more efficiently. In this context, Li-ion batteries are discussed in this study. Cells were compared with each other by conducting a comprehensive experiment. Due to the different types of such batteries, 2 different Li-ion battery cells, which are the most widely used in this study, were used in the experimental environment. The first is LG 21700 and the other one is Boston Swing 5300. With the help of Skyrc D100 V2 charger/discharger, the cells were charged at 1A, 5A, and 3A respectively, and discharged at 1A, 1.5A, and 2A. During the operations, temperature, internal resistance, current, voltage, and capacity values were measured and the results were obtained with the charger master software. With the results obtained, a detailed capacity and Soc calculation have been made to understand whether there is any loss. As a result of the measurements and calculations, it has been observed that the LG 21700 battery cell is more efficient in terms of performance. Keywords: Electrical vehicle, lithium-ion, battery cells, cylindrical cell, SOC, capacity, internal resistance, charge, discharge.
