“S” stands for the number of cells in series within the battery. For example, a 1S battery has one cell, a 2S battery has two cells in series, and so on.

For a single cell (1S), the LiHV Lipo battery’s minimum voltage should not fall below 3.3 volts, as it could cause irreversible damage to the battery. In the drone or RC model fields, for safety reasons, the cut-off voltage or safe voltage for LiHV Lipo batteries is typically set around 3.5 volts.

These parameters can be used to correctly set the cut-off voltage, storage voltage, and full charge voltage for each type of battery. Avoiding overcharging or over-discharging is key to prolonging the battery’s lifespan. By adhering to these guidelines, users can ensure that their batteries function efficiently and last as long as possible.

Based on the chart, we can observe how the voltage of a LiHV (Lithium High Voltage) battery varies with the discharge state for battery systems ranging from 1S to 6S. This can be applied to various types of equipment, such as drones, radio control cars, etc., that rely on these types of batteries.

However, these values are nominal and should be taken as a guideline rather than absolute values. In real-world applications, several factors can cause these values to deviate. For instance:

  • Manufacturing Differences: Different manufacturers may use different materials in the production of the batteries, which may vary in terms of energy density, internal resistance, the voltage gap between cells, heat dissipation efficiency, and so forth. All of these aspects can significantly impact the real performance of the battery.
  • Environmental Conditions: The operating environment can also have an effect on the performance of the battery. Extreme temperatures, either too high or too low, can affect the efficiency of the battery and hence the voltage levels at different states of charge.

Therefore, it’s crucial to consider these variables while evaluating the performance of LiHV batteries based on their state of charge. The users should be aware that the actual performance may differ from the specifications given due to the aforementioned reasons.

Frequently Asked Questions about LiHV

Q: Is a LiHV Lipo battery better than a regular Lipo battery?

A: LiHV batteries are a kind of Lipo battery that has been modified to safely charge to a higher voltage, often around 4.35V per cell compared to the typical 4.2V per cell of regular Lipo batteries. This means LiHV batteries can store more energy per unit weight than regular Lipo batteries, resulting in a higher energy density. This can provide longer flight times for drones or longer runtime for remote control cars and other similar applications.

However, the higher voltage of LiHV batteries may not be suitable for all devices. Some electronic components may not be rated for the higher voltage, which could potentially cause damage or shorten the lifespan of the device. Therefore, it’s crucial to ensure your device is compatible with LiHV batteries before using them.

Q: How to properly use LiHV batteries?

A: Charge with a LiHV-compatible charger: Because LiHV batteries can be charged to a higher voltage, you will need a charger that is designed to handle these higher voltages. Charging a LiHV battery with a regular Lipo charger could result in undercharging the battery.

Device compatibility: Make sure that your device is compatible with the higher voltage of a LiHV battery. Some electronic components may not be rated for the higher voltage and could potentially be damaged.

Q: In which fields are LiHV batteries most commonly used?

LiHV batteries are commonly used in applications where a higher energy density is beneficial. This includes RC vehicles, such as drones and cars, where the extra energy can lead to longer run times. They are also becoming increasingly popular in the FPV drone racing community due to their potential for increased performance.
