LiPo (Lithium Polymer) batteries have become increasingly popular in recent years due to their high energy density and low weight. They are widely used in drones, RC cars, and other applications where weight and power are critical factors. In this guide, we will focus on 4s LiPo batteries, which have a voltage of 14.8V and are commonly used in high-performance applications. We will provide you with a comprehensive wiring diagram that will help you connect your batteries safely and effectively.
Understanding LiPo Batteries
Before we dive into the wiring diagram, it’s essential to understand the basic characteristics of LiPo batteries. They consist of cells that are connected in series to increase the voltage and parallel to increase the capacity. A 4s LiPo battery has four cells connected in series, and each cell has a nominal voltage of 3.7V for a total of 14.8V.
LiPo batteries are popular due to their high discharge rates, which allow them to deliver a large amount of power quickly. However, they also have some limitations that you need to be aware of. They are sensitive to overcharging, over-discharging, and physical damage, which can cause them to catch fire or explode. Therefore, it’s crucial to handle and store them carefully and follow the recommended charging and discharging procedures.
Wiring Diagram for 4s LiPo Battery
The wiring diagram for a 4s LiPo battery is relatively simple and consists of four cells connected in series. It’s essential to ensure that the positive and negative terminals of each cell are connected correctly to avoid any short circuits or voltage imbalances. The following diagram shows the correct wiring for a 4s LiPo battery.
| Cell 1 | Cell 2 | Cell 3 | Cell 4 |
| + | – | + | – |
As you can see, the positive terminal of cell 1 is connected to the negative terminal of cell 2, and so on until the positive terminal of cell 4. This arrangement ensures that the voltage across each cell is added, resulting in a total voltage of 14.8V.
Common FAQs
Q: Can I connect two 4s LiPo batteries in series to get a higher voltage?
A: Yes, you can connect two 4s LiPo batteries in series to get a total voltage of 29.6V. However, it’s crucial to ensure that the batteries have the same capacity and are fully charged before connecting them. Also, it’s recommended to use a balancing charger to avoid any voltage imbalances between the cells.
Q: Can I connect two 4s LiPo batteries in parallel to get a higher capacity?
A: Yes, you can connect two 4s LiPo batteries in parallel to get a higher capacity. However, it’s crucial to ensure that the batteries have the same voltage and are fully charged before connecting them. Also, it’s recommended to use a balancing charger to avoid any voltage imbalances between the cells.
Q: Do I need to balance charge my 4s LiPo battery?
A: Yes, it’s recommended to balance charge your 4s LiPo battery to ensure that each cell has the same voltage. This will prevent any voltage imbalances between the cells, which can lead to overcharging or over-discharging. You can use a balancing charger that monitors the voltage of each cell and adjusts the charging current accordingly.
Q: Can I use a 3s LiPo battery with a 4s LiPo wiring diagram?
A: No, you cannot use a 3s LiPo battery with a 4s LiPo wiring diagram. The wiring diagram is specific to the number of cells in the battery, and using a different number of cells can result in overcharging or over-discharging. Make sure to use the correct wiring diagram for your battery to avoid any safety hazards.
Q: Can I discharge my 4s LiPo battery below the minimum voltage?
A: No, you should not discharge your 4s LiPo battery below the minimum voltage recommended by the manufacturer. Doing so can damage the battery and reduce its lifespan. Also, discharging below the minimum voltage can cause the battery to lose its capacity or even catch fire. Always follow the recommended charging and discharging procedures to ensure the safety and longevity of your battery.
Conclusion
In conclusion, the wiring diagram for a 4s LiPo battery is relatively simple and consists of four cells connected in series. It’s crucial to ensure that the positive and negative terminals of each cell are connected correctly to avoid any short circuits or voltage imbalances. Also, make sure to follow the recommended charging and discharging procedures and handle and store your battery carefully. By doing so, you can enjoy the benefits of high-performance LiPo batteries safely and effectively.
