5. What is the internal resistance of the battery?

When the battery is discharged, the internal resistance of the battery includes ohmic internal resistance and polarization resistance. The ohmic internal resistance is the electronic conduction resistance of each component, the ion conduction resistance and the sum of the contacts, which are related to the electrode structure and the assembly process. The polarization resistance is formed by the electrode reaction and is related to the nature of the electrode reaction and the battery material. The smaller the internal resistance of the battery, the lower the voltage drop inside the battery when the battery operates to output current, the higher the operating voltage and the larger current, the more the output energy and capacity.

Deep Groove Ball Bearings

Deep groove ball bearings The out looks of them are nearly the same,the only different is the size,you may need other models please check the following table for reference.are the most widely used bearing type and are particularly versatile.
They have low friction and are optimized for low noise and low vibration which enables high rotational speeds.
They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types.
deep groove ball

Deep groove ball bearings are divided into the following series: 6000series, 6100series, 6200series, 6300series, 6400 series, 6700 series, 6800 series,6900 series,16000 series etc.
