A 3.8V LiPo (Lithium Polymer) battery is a type of rechargeable battery with a nominal voltage of 3.8 volts per cell. This type of battery has gained popularity in various applications, particularly in the realm of drones, RC models, and other high-performance electronics. The 3.8V LiPo battery is often referred to as a "high voltage" (HV) LiPo, distinguishing it from the more common 3.7V LiPo batteries.

Difference Between 3.7V and 3.8V LiPo Batteries

The primary difference between 3.7V and 3.8V LiPo batteries lies in their nominal voltages and maximum charging voltages:

●3.7V LiPo Batteries: These have a nominal voltage of 3.7 volts per cell and a maximum charging voltage of 4.2 volts.

●3.8V LiPo Batteries: These have a nominal voltage of 3.8 volts per cell and can be charged up to a maximum voltage of 4.35 volts.

This difference in voltage translates into variations in energy density, performance, and usage applications. The 3.8V LiPo batteries are designed to handle higher voltages, offering improved energy storage and output capabilities.

Is it Safe to Charge a 3.8V Battery up to 4.35V?

It is safe to charge a 3.8V LiPo battery up to 4.35V, provided that the battery is specifically designed and rated for this voltage. Yes, it is safe to charge a 3.8V LiPo battery up to 4.35V, provided that the battery is specifically designed and rated for this voltage. The 3.8V rating of the battery refers to its nominal voltage, which is the average voltage during its discharge cycle. The full charge voltage, which is the maximum voltage the battery can be safely charged to, is indeed 4.35V for 3.8V LiPo batteries.Charging beyond 4.35V can be dangerous and should be avoided. It's crucial to use a charger that is compatible with HV LiPo batteries and to adhere to the manufacturer's guidelines for charging procedures to ensure safety and prolong the battery's lifespan.

Why Use a 3.8V LiPo Battery?

There are several reasons why one might opt to use a 3.8V LiPo battery:

●Higher Energy Density: The 3.8V LiPo batteries have a higher energy density compared to their 3.7V counterparts. This means they can store more energy in the same physical size or weight, providing longer runtimes for devices.

●Enhanced Performance: With the ability to handle higher voltages, 3.8V LiPo batteries can deliver more power to high-performance applications, resulting in better efficiency and performance.

●Better Power-to-Weight Ratio: Especially important in applications like drones and RC models, a better power-to-weight ratio means improved maneuverability and longer flight times without adding extra weight.

Advantages of Using 3.8V LiPo Batteries Instead of 3.7V

●Increased Capacity: Due to their higher nominal voltage, 3.8V LiPo batteries can store more energy, offering longer operational times for devices. With a higher voltage, the energy capacity (measured in watt-hours, Wh) of the battery increases even if the ampere-hour (Ah) rating remains the same. For example, a 3.7V LiPo with 1000mAh capacity stores 3.7Wh, while a 3.8V LiPo with the same 1000mAh capacity stores 3.8Wh.

●Improved Voltage Stability: These batteries maintain a higher voltage level during discharge, which helps in maintaining consistent performance until the battery is nearly depleted.

●Higher Peak Power: The ability to charge up to 4.35V means that the batteries can deliver higher peak power, which is beneficial for applications requiring sudden bursts of energy.

Advantages of Using High voltage LiPo batteries

High voltage (HV) LiPo batteries, such as the 3.8V lipo battery, offer several distinct advantages:

●Longer Runtime: With higher energy capacity, devices powered by HV LiPo batteries can operate longer on a single charge, which is crucial for applications like drones, where extended flight time is desired.

●Weight Efficiency: Higher voltage batteries can achieve the same power output with fewer cells, resulting in lighter battery packs. This is particularly advantageous in aviation and portable electronics.

●Performance Boost: Higher voltage batteries provide a performance boost due to the increased power output. This is beneficial for high-drain applications where maximum performance is required, such as racing drones or high-speed RC cars.

●Thermal Management: Higher voltage batteries can operate more efficiently, often generating less heat compared to lower voltage batteries. This can lead to improved thermal management and longer component life.

Conclusion

The 3.8V LiPo battery represents a significant advancement in battery technology, offering higher energy density, better performance, and improved efficiency. Its ability to safely charge up to 4.35V makes it a versatile and powerful option for high-demand applications. Whether for drones, RC models, or other electronic devices, the 3.8V LiPo battery provides numerous benefits that make it a superior choice over the traditional 3.7V LiPo battery. As a global leading lipo battery manufacturer, Grepow offers custom 3.8V, 3.85V and 3.9V high voltage battery cells to meet the needs of high energy density consumer and industrial applications.
