What does the number of C behind the battery mean? Represents the battery discharge capacity. This is the most important difference between ordinary lithium-ion batteries and power lithium-ion batteries. Power lithium-ion batteries require a large current to discharge. The discharge capacity of the battery is expressed in multiples (C), which means the maximum discharge current that can be achieved according to the nominal capacity of the battery. For example, the standard of a 1000mAh battery is 5C, then using 5x1000mAh, the battery can be discharged with a current intensity of 5000mA. If you use a low-C battery and discharge it at a high current, the battery will quickly be damaged or even spontaneously ignite. A 1000mAh battery, the maximum discharge current can reach 1000×10u003d10000 milliampere 10 ampere (A). In actual use, the discharge current of the battery is related to the load resistance. According to the Ohm's theorem, we understand that the voltage is equal to the current multiplied by the resistance, so when the voltage and resistance are constant, the discharge current of the battery is also constant. The internal resistance of the battery sometimes runs into the battery capacity and the voltage is normal, but the low voltage alarm is always in the circuit, which is that the internal resistance of a certain battery is too high. At this time, you can measure the voltage of each battery after discharging. If the voltage of a battery is much lower than the voltage of other batteries, you can throw it away. At this time, even if you don’t add new batteries, the battery The performance of the group will also be higher than before. Or you can use the replacement method until the battery pack is normal.
