A 18650 box mod is one of the most popular types of vape mods in the market. This type of mod is known for its durability, versatility, and power. It uses two or more 18650 batteries that are arranged in a series or parallel configuration. In this article, we will discuss in detail the wiring diagram of a 18650 box mod.
What is a 18650 battery?
A 18650 battery is a cylindrical lithium-ion battery that has a diameter of 18mm and a length of 65mm. It is commonly used in laptops, flashlights, and other electronic devices. This type of battery has a high energy density, which makes it ideal for high-power applications such as vape mods.
The 18650 battery has three parts: the cathode, the anode, and the electrolyte. The cathode is the positive terminal, while the anode is the negative terminal. The electrolyte is the medium that allows the flow of ions between the cathode and the anode.
Series Configuration
In a series configuration, the 18650 batteries are connected in a linear manner. The positive terminal of one battery is connected to the negative terminal of the next battery. This results in an increase in voltage and a decrease in capacity. The wiring diagram for a series configuration is shown below:
| Battery | Positive Terminal | Negative Terminal |
|---|---|---|
| Battery 1 | + | – |
| Battery 2 | + | – |
| Battery 3 | + | – |
In this configuration, the voltage is equal to the sum of the voltages of each battery. For example, if each battery has a voltage of 3.7V, then the total voltage would be 11.1V (3.7V x 3 batteries). However, the capacity is equal to the capacity of the lowest capacity battery in the series. For example, if one battery has a capacity of 2000mAh and the other two batteries have a capacity of 2500mAh, then the total capacity would be 2000mAh.
Advantages of Series Configuration
The main advantage of a series configuration is that it provides a higher voltage output. This is especially useful for high-powered devices that require a lot of power to function properly. Additionally, this configuration is easier to build and requires fewer components.
Disadvantages of Series Configuration
The main disadvantage of a series configuration is that if one battery fails, the entire circuit will fail. Additionally, this configuration may lead to voltage drop if the batteries are not well-matched in terms of capacity.
Parallel Configuration
In a parallel configuration, the 18650 batteries are connected side by side. The positive terminal of each battery is connected to the positive terminal of the other battery, and the negative terminal of each battery is connected to the negative terminal of the other battery. This results in an increase in capacity and a decrease in voltage. The wiring diagram for a parallel configuration is shown below:
| Battery | Positive Terminal | Negative Terminal |
|---|---|---|
| Battery 1 | + | – |
| Battery 2 | + | – |
| Battery 3 | + | – |
In this configuration, the capacity is equal to the sum of the capacities of each battery. For example, if each battery has a capacity of 2500mAh, then the total capacity would be 7500mAh (2500mAh x 3 batteries). However, the voltage is equal to the voltage of each battery. For example, if each battery has a voltage of 3.7V, then the total voltage would be 3.7V.
Advantages of Parallel Configuration
The main advantage of a parallel configuration is that it provides a higher capacity output. This is especially useful for devices that require a longer battery life. Additionally, this configuration provides a more stable voltage output and may extend the lifespan of the batteries.
Disadvantages of Parallel Configuration
The main disadvantage of a parallel configuration is that it requires more components and may be more difficult to build. Additionally, if the batteries are not well-matched in terms of capacity, this configuration may lead to uneven discharge and reduce the lifespan of the batteries.
Wiring Diagram
The wiring diagram of a 18650 box mod depends on the configuration used. However, there are some basic components that are required for a box mod. These include the batteries, the battery sled, the firing switch, the 510 connector, and the wiring. The wiring diagram for a basic box mod is shown below:
| Component | Wiring |
|---|---|
| Battery Sled | Connect the positive and negative terminals of the battery sled to the positive and negative terminals of the batteries. |
| Firing Switch | Connect the positive terminal of the firing switch to the positive terminal of the battery sled. Connect the negative terminal of the firing switch to the 510 connector. |
| 510 Connector | Connect the positive and negative terminals of the 510 connector to the positive and negative terminals of the firing switch. |
This wiring diagram is for a basic box mod. However, there are other components that can be added to the circuit, such as the voltmeter, the wattmeter, and the potentiometer. The wiring diagram for a box mod with additional components will vary depending on the configuration used and the specific components added.
