1. The relationship between the price and capacity of 18650 lithium batteries
Capacity is a hot topic for most new users, and the larger the capacity, the higher the cost. We know that currently, the most stable battery capacity range in the entire 18650 lithium battery market is about 2200-3000mAh, and the highest battery capacity is about 3200mAh. Generally speaking, the higher the capacity, the higher the battery price. So, when purchasing cylindrical lithium batteries in your daily life, you must choose a solution that suits your power supply needs, rather than blindly pursuing high capacity lithium batteries.
2. The relationship between the price of 18650 lithium batteries and internal resistance values
At present, there are not many devices in China that test battery capacity and internal resistance, and for most ordinary households, there is not much time to pay attention to the real parameters of 18650 lithium batteries. However, for procurement personnel engaged in lithium battery procurement business, grasping the range of internal resistance can help to obtain the final price of lithium batteries more accurately. Generally speaking, the larger the internal resistance, the smaller the capacitance, and the lower the price and quality of 18650 lithium batteries. For applications that require more power, the resistance is relatively small, and the price of 18650 lithium batteries is naturally relatively high. So another factor that affects battery prices is its resistance.
3. The relationship between the price of 18650 lithium batteries and the quality of battery cases
It is generally believed that the price of the 18650 lithium battery casing is not sensitive to most battery buyers, but we have to say that the quality of the casing directly affects the final quality stability of the battery. So the quality of the casing will also affect the price of 18650 lithium batteries.
4. Price and Explosion proof Design of 18650 Lithium Battery
Most 18650 lithium batteries are designed with steel shells, so it is obvious that this type of battery has the possibility of accidents. Therefore, explosion-proof design can effectively prevent such accidents and even tragedies from happening. Therefore, explosion-proof design is another factor that affects the price of 18650 lithium batteries.
5. The relationship between the price of 18650 lithium batteries and intelligent battery management systems
The price of 18650 lithium batteries is based on the use of IC circuits to control various overcharging, overflow, and protection. However, with the continuous improvement of modern technology, high-quality lithium batteries are fully capable of designing suitable intelligent battery management systems. The design of an intelligent battery management system is another important factor affecting the price of lithium batteries.
