What is the correct way to use forklift lithium batteries

Everyone knows that the greater the mAh value of the battery, the greater the capacity of the battery. The greater the C number, the battery power will be sufficient; but what is the scientific and accurate meaning of these things? I'm afraid there are very few people who can make it clear~~ Let's popularize the knowledge here, so that everyone can know more about the various batteries in their hands. First of all, you have to be clear, whether it is the 3.7V of the lithium battery or the 1.2V of the nickel-metal hydride, it does not refer to the voltage when the battery overflows. As for the lithium battery, the voltage after the overflow generally reaches 4.2V. , Generally, the output voltage indicated above is 4.2V, and the Ni-MH overflow battery can reach about 1.5V. Then there are capacity and discharge rate. The capacity of a lithium battery is in mAh (milliampere hour), and the discharge rate is in C. As for the C number, simply say that 1C is different for different capacity batteries. 1C means that the battery can continue to work for 1 hour after being discharged with a discharge rate of 1C. For example, if a battery with a capacity of 2200mAh continues to work for 1 hour, the average current is 2200mAh, which is 2.2A; 2.2A is the 1C of this battery. If it is nominally 30C, then the maximum discharge current of this battery is 2.2A*30u003d66A. It means that this battery is safe under 66A use. All in all, the smaller the C number, the longer the maximum battery current discharge time. However, the battery life of the forklift mostly depends on your driving habits, so it is not enough to buy a battery and just look at the C number. The discharge of a battery with a small C number may also be greater than a discharge with a large C number, because it is also related to the capacity of the battery. It can also be said that a battery with a large C number has stronger vitality; if a battery with a small C number is discharged with a high current, the battery may be scrapped in a few strokes! At present, the lithium batteries used in forklifts are called lithium polymer batteries, generally referred to as lithium batteries. Due to the large quality gap between brands, their prices are also uneven. The following takes 11.1V remote control airplane model lithium battery as an example to illustrate how to use lithium battery correctly. Generally, the 11.1V remote control airplane lithium battery is made up of 3 lithium batteries in series (the most popular 3S battery, Figure 1), that is, the voltage of each battery is 3.7V. The voltage marked on the lithium battery of models, mobile phones, cameras, etc. is called the marked voltage, which is obtained from the uniform working voltage. The actual voltage of a single-chip lithium battery is 2.75~4.2V, and the capacity of the lithium battery is the amount of electricity obtained by discharging 4.2V to 2.75V. The remote control airplane lithium battery must be used within the voltage range of 2.75~4.2V. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
