Hi friends, welcome to the new post. In this post, we will discuss the 2025 Comprehensive Guide on 3S Lipo Battery & its Applications, Pros & Cons. The 3S lipo is a rechargeable battery configured on lithium-ion technology. It uses polymer electrolytes rather than liquid electrolytes. It comes with high energy density in a compact structure and is best for small sizes where weight is important. The 3S lipo comes with 3 individual batteries in a single pack. So let’s get started with 3s lipo battery
What is a 3S Lipo Battery?
The 3S lipo battery is a lithium polymer battery for RC uses and electronics. The 3S is a battery pack with three series of connected cells.
The overall voltage for this battery is 11.1 volts (3 cells x 3.7 volts), with each cell having 3.7 volts.
This balanced value offers good power to operate different RC models.
This battery is neither unimpressive nor overbearing, offers good operation, is easy to use, and is best for RC users.
How Does a 3S Lipo Battery Work?
The Lipo battery is made with separate cells and connected to make a specific battery. One Lipo cell comes with a nominal voltage of 3.7 volts. Connection in series voltage increase that means 7.4 volts will get from two cell battery, 11.1 volts for three cell battery. and 14.8V for a 4-cell battery, etc.
Advantages of 3S Lipo Batteries
It is best for starters since their high energy density helps to store enough energy in small areas. It covers longer runtime for RC cars, drones, and some other electrical devices.
Its good discharge rate helps to generate steady power generation and high power operation.
This battery is less weight than other nickel batteries, reducing the total weight of devices.
Disadvantages of 3S Lipo Batteries
- Some disadvantages of lip batteries are
- It supported less recharge life, which is about 300 to 400 cycles.
- It needed special care at the time of charging, discharging, and storage.
- It is high-cost and double the price of a Li-Ion battery.
Applications of 3S Lipo Batteries
- Its common uses are
- Drones, radio-controlled equipment, and aircraft.
- Personal electronics.
- Electric vehicles.
- Uninterruptible power supply systems.
- Jump starter.
Maintaining of 3S Lipo Batteries
- To maintain the battery condition, do not drain the cell less than 3.0 volts. So 3S lipo will be dead for 9 volts. But there is a storage charge that is a safe voltage for cells to work longer, which is more than 3.8 volts.
- Not charging over 4.2 volts per cell or over discharging less than 3 volts per cell. Do not leave Lipo Pakes unattended at the time of charging in the vehicle. Do not leave the battery pack plugged into the vehicle when not in use.
Understanding LiPo Battery Numbers
These numbers on the Lipo battery define the configuration, and the battery that comes with 2S means it has two cells in a series. 3S means three cells are in a series combination.
High voltage is high power, and high capacity is longer working time.
Here is the voltage for the Lipo types used for RC cars:
- 1S battery: 1 x 3.7V = 3.7V
- 2S battery: 2 x 3.7V = 7.4V
- 3S battery: 3 x 3.7V = 11.1V
- 4S battery: 4 x 3.7V = 14.8V
- 5S battery: 5 x 3.7V = 18.5V
- 6S battery: 5 x 3.7V = 22.2V
- 8S battery: 5 x 3.7V = 29.6V
What is the voltage of 3 S LiPo batteries?
The voltage of the S series can be defined through the battery name. In the 3S lipo battery, the nominal voltage is 11.1. Each cell provides 3.7 volts when connected in series. In 3S battery, the full voltage rate is
- Fully charged voltage = 12.6V (4.2V per cell)
- Nominal voltage = 11.1V (3.7V per cell)
- Low voltage cutoff = 9V (3V per cell)
11.1 v lipo battery
11.1V Lipo comes with 3 cells; when completely charged, it has 12.6 volts combined or 4.2 volts for single cells. 11.4 volts is about 50 percent of the capacity left.
This battery is used in airsoft guns, planes, remote control cars, etc.
3S lipo rc battery
The 3S Lipo battery is a common lithium polymer alternative to RC electronics. The 3S defines the battery pack as three series of connected cells. The total voltage is 11.1 volts, and each cell has a nominal voltage of 3.7 volts.

What is LiPo battery cell count?
LiPo battery pack configured denoted of lipo cells in series and number of lipo cells in parallel combination. The 4S2P pack can come with four cells in series combination and two cells in parallel, for a total of 8 cells. The 4000mAh 4S2P pack comes with a capacity of 4000mAh (2 x 2000mAh) and a voltage of 14.8V (4 x 3.7V).
LiPo batteries each cell has a nominal voltage of 3.7V. 1S = 1 cell = 3.7V. 2S = 2 cells = 7.4V. 3S = 3 cells = 11.1V.
What is LiPo battery capacity?
Battery capacity is the amount of energy stored and measured in milliampere hours or ampere hours. Capacity is about 28000 Mah,
What is Discharge Rating (C Rating)?
The C rate is a measurement of the rate over which the battery is discharged according to high capacity. The 1C rate is the discharger current that discharges the battery in one hour. In case of a capacity of 100 Amp-hrs, a discharge current of 100 Amps
discharge C rate = discharge current/battery capacity
Such as if a 3.7v 1000mAh LiPo battery discharges 5000mA, then its
discharge C rate=5000mA/1000mAh=5C.
relationship between C rating and discharge time:
| C Rating | Discharge Time |
|---|---|
| 1 | 1 hour |
| 2 | 30 minutes |
| 3 | 20 minutes |
| 4 | 15 minutes |
| 5 | 12 minutes |
capacity of 3S LiPo batteries
3S Lipo Battery 2000mah
- This battery is stable for weight and power ratio. The average cost of this battery is about 20 to 25 dollars based on battery type. It makes the battery best for RC projects like RC plans.
3S Lipo Battery, 3500mah
- It is best for different uses, but not limited to high-performance drones, RC aircraft, medical instruments, and cameras. Its price is $30 to $35.
3S Lipo Battery 5000mah
- It is used for high-performance devices. Since it comes with high power capacity, the runtime of electronic projects becomes double. It is best for RC planes and vehicles, drones, etc.
Internal Structure of a Lithium Polymer Battery
- 4 components of this battery are a positive electrode, a negative electrode, a separator, and an electrolyte.
- The separator can be of a polymer, such as a microporous film of polyethylene; if the cell has a liquid electrolyte, it will be polymer.
- The positive electrode is divided into three parts: lithium-transition metal oxide (LiCoO2 or LiMn2O4), a conductive additive, and a polymer binder of poly(vinylidene fluoride) (PVDF).
- The negative electron also has three parts replacing carbon with lithium-metal-oxide. The main difference between lithium polymer cells and lithium-ion cells is the physical layout of electrolytes. iPo cells use dry solids, gel-like, while Li-ion cells use liquid electrolytes.
How long does a 3S LiPo battery last?
- The capacity of the battery is important for working longer. High battery capacity means longer backup. Such a 3S lipo battery with 500 mAh can work longer than a 200 mAh battery.
- The devices that use more current will draw larger current. The larger drone depletes the battery faster than that low-power toy.
- The discharge is rare and also affects battery backups. 3S Lipo battery has a high continuous discharge rate of 10C to 20C. If we cross it, it will reduce battery working life.
- The 3S battery 5000 mAh comes with this runtime.
- Connected with a 1000 mA device: 5-hour
- Connected with a 2000 mA device: 2.5 hours
- Powering a 5000mA device: 1 hour
