4s Lipo Battery Full Details

Understanding 4s Lipo Batteries

A type of lithium polymer battery with a nominal voltage of 14.8 volts is a 4S lipo battery. The “4s” in its name stands for the battery pack’s four cells, each of which has a nominal voltage of 3.7 volts. The voltages of the cells add up when they are connected in series, producing a voltage of 14.8 volts overall.

These batteries’ high energy density allows them to fit a lot of energy into a relatively tiny and light body. RC helicopters, drones, remote-controlled cars, and other electronic gadgets that need a dependable power source all frequently use them.

Advantages of 4s Lipo Batteries

  • Higher Voltage: The increased voltage of 4S lipo batteries in comparison to other battery types is one of its main advantages. They may produce more power because of the greater voltage, which qualifies them for high-performance applications.
  • Longer Runtime: In comparison to conventional batteries, 4s lipo batteries offer a longer runtime because of their higher energy density. They are therefore perfect for uses that call for prolonged usage times.
  • Lightweight Design: In comparison to other battery types with the same power ratings, 4s lipo batteries are substantially lighter. The device’s overall weight is decreased and its maneuverability is increased thanks to the lightweight construction.
  • Fast Charging: Compared to batteries with different chemistries, these batteries can be charged more quickly. A 4s lipo battery can be recharged quickly with the appropriate charger.
  • Low Self-Discharge Rate: Due to their low self-discharge rate, 4S lipo batteries may maintain their charge for a long time when not in use. Because of this quality, they are practical for sporadic use.

Factors to Consider When Choosing a 4s Lipo Battery

When selecting a 4s lipo battery for your device, several factors need to be taken into consideration:

  1. Capacity: The battery’s capacity impacts how long your gadget will operate. While offering more usage time, higher-capacity batteries may also be heavier and bulkier.
  2. C-Rating: The maximum safe discharge rate of a battery is indicated by its C-rating. Although they might cost more, batteries with a higher C rating can produce greater power.
  3. Connector Type: Be sure your device can use the battery’s connector type. XT60, EC3, and Dean’s connectors are typical types.
  4. Size and Weight: Consider the battery’s physical size and weight to make sure it fits properly in your smartphone without altering its balance.
  5. Brand and Quality: Choose batteries from reliable companies with a reputation for reliability and safety. Batteries of poor quality may not deliver the promised capacity and may be prone to malfunctions.

Charging and Discharging 4s Lipo Batteries

To preserve the longevity and safety of 4s lipo batteries, due care and attention must be taken when charging and discharging them. Observe some rules:

  • Charging: Use only a charger made especially for lipo cells. Change the charger’s settings to those recommended by the battery’s manufacturer for voltage and current. Avoid overcharging or charging at high currents because these actions can harm batteries or possibly put you in danger of a fire.
  • Discharging: It is best to avoid completely discharging the battery because doing so could result in permanent harm. To avoid over-discharge, most devices feature built-in low-voltage cutoffs. Use a voltage checker to keep track of the battery voltage while using your device if it lacks this capability.
  • Storage: Store the battery at about 50% charge if you won’t be using it for a long period of time and keep it somewhere cool and dry. It is best to avoid storing the battery at full or empty charge levels because doing so can reduce its longevity.

Safety Precautions for Handling 4s Lipo Batteries

While 4s lipo batteries offer numerous benefits, it’s essential to handle them with care to prevent accidents or damage. Follow these safety precautions:

  • Storage: 4s lipo batteries should be kept in a fireproof bag or container that is made just for lipo batteries. In the event of a battery failure, this will contain any potential fire threats.
  • Transportation: Make sure lipo batteries are adequately shielded when carrying or moving them to avoid physical harm or short circuits. Keep kids away from metallic or pointy objects.
  • Avoid Overheating: Avoid exposing 4s lipo batteries to intense heat or sunshine. The battery may bloat, leak, or even explode under high temperatures. Keep them somewhere cool with good ventilation.
  • Balance Charging: Always use a balance charger while charging multiple-cell lipo batteries to guarantee that each cell receives an equal amount of power. This increases the battery’s longevity and aids in maintaining its performance.
  • Monitoring: Never leave the battery unattended while it is charging. Keep an eye on the charging procedure at all times, and be ready to act quickly if anything goes wrong.


A dependable power source for many electronic gadgets, such as remote-controlled cars and drones, is provided by 4S lipo batteries. They have gained popularity among professionals and hobbyists due to their high energy density, lightweight construction, and extended runtime.

You may choose, use, and maintain 4s lipo batteries in an informed manner by being aware of their characteristics, benefits, and safety measures. Always put safety first and keep in mind the instructions given by the battery manufacturer.


What does “4s” mean in a 4s lipo battery?

This is why you may occasionally hear someone refer to a “4S” battery pack; it denotes that the Series has 4 cells. A three-cell (3S) pack has a voltage of 11.1V, a four-cell (4S) pack has 14.8V, etc.

How long does a 4s lipo battery last?

A 4S lipo battery’s lifespan is influenced by a number of variables, including usage patterns, charging and discharging habits, and general maintenance. A 4s lipo battery can survive anywhere from 150 to 300 charge cycles or more with good maintenance and adherence to manufacturer recommendations.

Can I use a 4s lipo battery in any device that requires batteries?

No, 4S lipo batteries are not compatible with all devices. When utilizing a 4s lipo battery, it is essential to confirm the voltage and power specifications of your device. The gadget may be damaged or put at risk for injury if a battery with a greater voltage is used than the one the device can manage.

Are 4s lipo batteries safe to use?

The majority of the time, 4s lipo batteries are secure when handled and utilized properly. They do, however, need to be handled carefully and attentively to avoid mishaps. To guarantee safe use, adhere to the safety warnings already indicated and never abuse or improperly handle the batteries.

What should I do if my 4s Lipo battery swells or gets damaged?

Stop using your 4S lipo battery right away and take the necessary precautions if you observe any swelling or damage. Carefully remove the battery from the gadget, then place it in a bag or container that can withstand fire. Follow local laws and regulations while disposing of bloated or broken batteries.

Can I charge a 4s lipo battery with a regular charger?

What does LiPo stand for?

The Lithium Polymer battery is also known as LiPo. It is a rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid electrolyte.

What is the difference between a 2S and a 4S LiPo battery?

The difference between 2S and 4S LiPo is the number of cells in the battery. LiPo cells are rated at 3.7v, so a 2S LiPo is a 2-cell battery with 7.4v, a 3S has 11.1v, a 4S has 14.8v, and a 6S has 22.2v.

What is the capacity of a LiPo battery 4S?

A LiPo battery 4S is a type of rechargeable battery that consists of four cells connected in series. Each cell has a nominal voltage of 3.7 volts, so the total voltage of a LiPo battery 4S is 14.8 volts. The capacity of a LiPo battery 4S depends on the size and quality of the cells, but it is usually measured in milliampere-hours (mAh). The higher the capacity, the longer the battery can provide power to a device. For example, a LiPo battery 4S with a capacity of 5000 mAh can theoretically deliver 5 amps of current for one hour, or 10 amps for half an hour before it needs to be recharged.
