　　For lithium-ion batteries, the voltage usually reaches 4.2V after being fully charged. It is believed that most people have a mobile phone battery with universal charging. You can take a look, and the output voltage indicated on it is generally 4.2V. And nickel hydrogen can reach around 1.5V when fully charged. Besides voltage, then capacity and discharge rate. The capacity of the battery is measured in mah (milliampere hour), and the discharge rate is measured in C. To put it simply, the C number. 1C is different for batteries of different capacities. 1C refers to the battery that can operate continuously for 1 hour with 1C discharge. For example, if a battery with a capacity of 1500mah operates continuously for 1 hour, the average current is 1500mah, which is 1.5A. 1.5A is the 1C of this battery. If the above nominal value is 10C, then the maximum discharge current of this battery is 1.5A * 10=15A. This means that this battery is safe when used at 15A. For example, 1C in a 1000mah capacity is 1000ma, which is 1A. If the nominal discharge current above is 15C, the maximum discharge current is 1A * 15=15A, and the maximum discharge current of this battery is also 15A. However, the battery above operates at 15A and is discharged at 10C. In theory, the maximum current operation is 60/10=6 minutes. And 1000mah operates at 15A, which is a discharge at 15C. Theoretically, working at this current can last for 60/15=4 minutes. So relatively speaking, a 1500mah, 10C battery needs to be used for a longer time. So just looking at the C number when buying a battery is not enough. A discharge battery with a small C number may have a larger discharge than a battery with a large C number. This is related to capacity.
