One of the most frequent queries is should I use a 2S or 3S battery? Are you also looking for the answer to it? Then you are in the right place. I’ll give it a go today for you.
Lipo battery cells come with a variety of cell numbers in series, such as 2s, 3s, 4s, 6s, etc. Their varied voltages produce different discharge performances. Today, I will compare a 2S and a 3S lipo battery to show you how they differ.
In the following passage, you will find a comparative study of 2s and 3s batteries and also which lipo battery has a long time.
2s vs 3s Lipo Run Time
LiPo batteries, also known as lithium polymer batteries, have entirely transformed the electric radio-controlled (RC) industry, particularly for airplanes, helicopters, and multi-rotors. They are the main factor making the electric flight more attractive than aircraft with gasoline engines nowadays.
A 2s battery means two Lipo battery stacks in series. As well as, 3s means that 3 Lipo batteries connected in series. Each battery has a standard voltage of 3.7 volts, a full voltage of 4.2 volts, and a storage voltage of 3.8 volts. Each battery has a standard voltage of 3.7 volts, a full voltage of 4.2 volts, and a storage voltage of 3.8 volts.
These batteries are generally used for RC hobbies, like RC cars, Drone/UAVs, RC Airplane/Heli, and FPV. It is important to know how to choose the best Lipo battery to get the best flight or running period and efficiency.
Lipo Battery: 2s vs 3s Run Time
According to the test results, the 2s battery’s depletion time is less than that of the 3s battery under the same conditions of discharge duration and capacity.
You lose less power and get a longer run time because the motor can turn more effectively at higher voltages.
Your RC car will be lighter and more responsive because the 3s battery is lighter than the 2s at the same capacity.
Theoretically, a 3s battery of the same capacity can extend your battery life by more than 33% and have a greater effect if it is configured to work with your power system.
According to the Formula: Volts *amps = watts,
the calculation result:
Racers desire to move to higher voltage batteries to extend run time or achieve better punch since some race regulations have weight and size restrictions on batteries.
It is important to note that many individuals are under the misconception that larger batteries lead to longer runtimes. The efficiency and current consumption of the RC car decrease as capacity increases. Even worse, it produces a lot of heat and burns the motor.
The Impact 0f 2s and 3s
The 3S battery has a greater voltage than the 2S battery under the same power. The voltage output influences the speed of the motor. For instance, for a 4200kv motor, the predicted motor speeds are 31080RPM (2s lipo) and 46620 (3s Lipo).
We observed, that 3s can supply the motor with more current, therefore C- The higher the rate, the higher the power. For an RC car, a 3s battery allows for faster driving.
The 3s battery uses less current to perform the same task than the 2s battery, which lessens the load on the battery and increases its lifespan. You’ll notice that the remote control car is significantly different from to drive; it is more sensitive and capable of performing challenging moves like looking up, flipping, jumping, and so forth.
LiPo batteries are composed of many LiPo cells, each of which generates a nominal 3.7 volts of electricity. So, if you add a volt to an electrical motor with a 3,500kV rating, it will spin at a rate of 3,500 RPM. That motor will rotate at about 25,900 RPM with a 2S LiPo battery. It will spin at an incredible 38,850 RPM on a 3S. Therefore, the more voltage you have, the faster you will go.
Benefits of Lipo Battery
RC LiPo batteries have four key advantages that make them ideal for RC helicopters and RC planes compared to more traditional rechargeable battery types. These are:
- Lipo battery has a large capacity means RC LiPo batteries can store a lot of energy in a small space.
- RC LiPo batteries have high discharge rates to power even the most demanding electric motors.
- There is no “memory effect” with LiPos, unlike other batteries.
- RC LiPo batteries are light in weight and can be manufactured in any size and shape.
Disadvantages Of Lipo
- LiPo batteries only have an average lifespan of 150–250 cycles.
- If the battery is damaged, the critical chemistry could explode, setting it on fire.
- It requires particular care when charging, discharging, and storing, as it has complexities.
Frequently Asked Questions (FAQs)
How long does a 3s LiPo battery run?
“For instance, if your battery has three cells, you should charge it to 11.4V for storage.” Your battery is generally safe to use, provided you kept them at the proper storage voltage. However, LiPo batteries are delicate, so while they can survive more than four years when placed on a shelf, you should keep your expectations in check.
How long do LiPo batteries run time?
LiPo batteries can last from two and three years, or 300 and eight hundred charge cycles. A LiPo battery, however, can last around 25 minutes to a few days on a single charge.
How to keep LiPo batteries in peak condition?
The same LiPo battery can be made to live longer than someone else’s with the right maintenance.
- Never let the battery get to the point of being fully dead.
- Never charge your batteries too much (and never over-discharge them, too)
- Discharging at a current greater than its rated limit will prevent overtaxing the battery.
- Don’t allow batteries to become too hot
- They should be charged, stored, and discharged in a metal ammo box, a fireproof LiPo safety bag, or some other fireproof container.
To sum up, Lipo batteries are ideal for all kinds of gadgets. It can last for a long time providing energy and safety. In comparison between 2s and 3s, 3s battery run longer than 2s. In addition, your car’s speed will largely be determined by the voltage of the battery pack.
