What is the voltage of the time travel machine? Is it out of power?
In recent years, FPV Drone has become a new favorite among technology enthusiasts and model aircraft players due to its unique experience of high-speed flight and first-person perspective control. However, for novices, how to judge whether the battery voltage of the traversal machine is exhausted is a key issue. This article will combine the hot topics and hot content on the entire network in the past 10 days, analyze the voltage threshold of the traversing machine in detail, and provide structured data for reference.
1. Basic knowledge of time travel battery

Travel machines usually use lithium polymer batteries (LiPo Battery), whose voltage range is different from ordinary lithium batteries. The nominal voltage of a single LiPo battery is 3.7V, the full voltage is 4.2V, and the discharge cut-off voltage is generally 3.0V-3.3V. The following is the voltage range of common battery packs (S number):
| Battery type | Nominal voltage | Full voltage | Discharge cutoff voltage |
|---|---|---|---|
| 1SLiPo | 3.7V | 4.2V | 3.0V-3.3V |
| 2SLiPo | 7.4V | 8.4V | 6.0V-6.6V |
| 3SLiPo | 11.1V | 12.6V | 9.0V-9.9V |
| 4SLiPo | 14.8V | 16.8V | 12.0V-13.2V |
| 6SLiPo | 22.2V | 25.2V | 18.0V-19.8V |
2. How to determine if the time traveling machine is out of power?
When the battery voltage of the time-travel machine is lower than a certain threshold, it will be considered "depleted". Here are a few ways to tell if your battery is dead:
1.voltage alarm: Most of the flight control or video transmission systems of the aircraft will be equipped with a low-voltage alarm function. When the battery voltage drops to a preset threshold (such as 3.5V/single cell), the flight controller will sound an alarm.
2.Flight time estimate: Depending on the battery capacity and flight style, usually a 1500mAh 4S battery can last 5-8 minutes under high-intensity flight. If the flight time is significantly shortened, the battery may be aging or the voltage is insufficient.
3.Battery back pressure phenomenon: The battery voltage will drop due to load during flight, but the voltage will rise slightly after stopping flight. If the voltage is still lower than 3.3V/single cell after back-pressure, it means the battery is close to exhaustion.
3. Hot topics on the Internet: Battery management skills for time-travel machines
Through the analysis of popular content on the Internet in the past 10 days, the following are the battery management skills that players are most concerned about:
| hot topics | focus of discussion | Recommended voltage threshold |
|---|---|---|
| Extended battery life | How to avoid overshoot | Single section is not less than 3.5V |
| Effects of low temperature flight | Winter voltage sag | Reserve 0.2V margin |
| Fast charging and balanced charging | Charging efficiency and safety | Fully charged 4.2V±0.05V |
| Second hand battery testing | Internal resistance and voltage relationship | Storage voltage 3.8V-3.9V |
4. Practical suggestions: voltage thresholds in different scenarios
Depending on the flight scenario, it is recommended to use differentiated voltage thresholds:
1.racing flight: When pursuing extreme performance, the low-voltage alarm can be set to 3.2V/single section, but the flight time must be strictly controlled.
2.aerial photography flight: In order to ensure safety and redundancy, it is recommended that the alarm threshold be set to 3.6V/single section and 20% of the power be reserved for return.
3.Novice exercises: 3.7V/single cell alarm is recommended to avoid sudden power outage due to unskilled operation.
5. Summary
The "depleted" voltage of the flying machine is not a fixed value and needs to be comprehensively judged based on the battery type, flight scenario and equipment characteristics. By properly setting low-voltage alarms, monitoring flight time and paying attention to battery health, battery life can be effectively extended and flight safety ensured. It is recommended that players regularly use professional tools to check the internal resistance and voltage consistency of the battery to obtain the best flight experience.
