Custom 24V lithium batteries require several 18650 lithium batteries.convenient energy storage power supply wholesale

　　 D USB 1.5V 6000mWh

　　Customized 24V lithium batteries must have a battery of 7 knots 18650 to connect together, and 24V lithium batteries can be used at the same time. The rated voltage of 18650 was 3.7 volts, but we directly measured the voltage of the 18650 battery to 4.2 volts. Many people are struggling, is it 6 knots 18650, or 7 sections 18650?

　　In fact, the voltage on the 18650 battery is 4.2 volt. When it is loaded, its voltage will drop sharply, and when it lasts longer (the smaller the battery capacity), the lower it will be Essence Below is a 18650 battery. Under different discharge current, its voltage distribution curve (note:: The discharge voltage distribution of the 18650 battery has different differences, and the chart below is only for reference).

　　From the discharge voltage curve of the single section 18650, it can be seen that if 6 batteries are connected, the current is 4.2 V, and its current is 1/21 V. This means that when your battery pack releases about 3/4 of the electricity, the inverter (or electronic equipment) will be in a state of no work, that is, the 24 V lithium battery of the 18650 18650, you can only use it to use it. 3/4.

　　In this way, in order to maximize the capacity of the battery, the number of batteries required for 18,650 in series, that is, the rated voltage 18,650. In the formal rated electricity pressure, the effects of load and discharge are also considered.
