What voltage level should a LiPo battery be?
The nominal voltage of a fully charged LiPo battery is 3.7 volts per cell. For example, a 2-cell LiPo battery will have a nominal voltage of 7.4 volts, and a 3-cell LiPo battery will have a nominal voltage of 11.1 volts.
When a LiPo battery is fully charged, its voltage will be slightly higher than the nominal voltage. The voltage will gradually drop as the battery discharges.
However, it is essential to note that LiPo batteries should never be discharged below their minimum safe voltage rating. Discharging a LiPo battery below its minimum safe voltage can damage the battery and reduce its performance or even cause a fire or an explosion.
What is the maximum voltage for a 2 cell LiPo battery?
The maximum voltage for a 2-cell LiPo battery is 8.4 volts. It is crucial to avoid overcharging your LiPo batteries since it can cause them to catch fire, explode, or even burn your house down.
When charging your 2-cell LiPo battery, it is best to use a charger that has an automatic shut-off feature, which prevents overcharging. You should also charge your LiPo batteries in a fireproof container or on a fireproof surface to prevent accidental fires.
What is the voltage of a 4 cell LiPo battery?
The nominal voltage of a fully charged 4-cell LiPo battery is 14.8 volts. The actual voltage of a fully charged 4-cell LiPo battery varies between 16.8 and 14.0 volts, depending on the type of charger, its capacity, and its age.
It is essential to store your 4-cell LiPo battery in a cool and dry place, away from direct sunlight or excessive heat. Prolonged exposure to heat can reduce your battery’s performance and lifespan.
What voltage is a 7.4 volt LiPo battery fully charged?
A 7.4 volt LiPo battery is a 2-cell battery, and its nominal voltage when fully charged is 8.4 volts. However, its actual voltage when fully charged can vary between 7.6 volts and 8.4 volts, depending on the type and capacity of the battery.
It is best to use a LiPo battery charger that has a voltage monitoring feature to prevent overcharging or undercharging your battery. Overcharging or undercharging your LiPo battery can damage it, reduce its lifespan, or even cause it to catch fire.
Conclusion
The LiPo battery voltage chart is essential for anyone who uses LiPo batteries. Knowing the nominal and actual voltage of a LiPo battery at different levels of charge can help you use it more safely and effectively.
Remember never to overcharge or undercharge your LiPo batteries, and always store and charge them in a safe place. By following these guidelines, you can ensure that your LiPo batteries last longer and keep you powered up during your RC adventures!
