Analysis of common nouns of lithium battery

1. Battery capacity (mah): The capacity of the battery is usually calculated by AH (ampere/hour). In model airplanes, the capacity is usually small, so it is accurate to mAH (milliampere/hour). In fact, the correct expression of mah is mA/H. m represents the unit millisecond, A represents the current unit ampere, and H represents the time unit hour. For example, 2200mah means that the battery can be discharged at a constant current of 2200 mA for 1 hour, and the amount of electricity released is the capacity of the battery. 2. Discharge rate (C number): In addition to the battery capacity, the more important thing is the discharge rate, which is the C number we often say! 1C means double the discharge current. For example, for a 2200mah battery, 1C currentu003d2.2A, then 30C is: 2.2A×30Cu003d66A. This is the maximum output current of the battery. 3. Section (S): Lithium battery cell voltage is 3.7V, a single cell is called CELL, or S is used to express, if you want to obtain a higher voltage, you need to overlap multiple cells in series For example, 2S (3.7+3.7u003d7.4V), 3S (11.1V) and so on.
