HOME / 3s 25a Lithium Ion Bms – For 11.1v Battery - KKA Industrial Storage
LiPo batteries come with all kinds of numbers, ratings, and capacities. So, I wanted to take a moment to discuss the differences in 2S and 3S LiPos in simple terms. A 3S LiPo is more powerful than a 2S pack. Full stop. So, higher voltage batteries will have a higher “S” number. However,. There are three numbers you need to understand on a LiPo battery, and they are: 1. Voltage or S 2. Capacity or mAh 3. Discharge or C rating The voltage (S) is a measure of how powerful your battery is. So if your RC car or Plane has an ESC and motor that can. When you look at any LiPo battery, you will see the letter S on the pack. The S tells you how many cells the pack contains. So, a 3S. The difference between 2S batteries and 3S batteries is the voltage. Each cell in a LiPo pack provides 3.7 volts. To calculate the voltage of a LiPo pack, multiply 3.7 volts by the number. The “C” rating on a LiPo battery stands for the discharge rate. What you need to know is the higher the C rating, the better. High C rating.
[PDF Version]Each cell in a LiPo pack provides 3.7 volts. To calculate the voltage of a LiPo pack, multiply 3.7 volts by the number of cells. Again, the number S number tells you the number of cells. A 2S LiPo battery has two cells and a voltage of 7.4v while 3S means the LiPo has a voltage of 11.1v and three cells. 2S VS 3S LiPo Battery – What Does The S mean?
The difference between 2S batteries and 3S batteries is the voltage. Each cell in a LiPo pack provides 3.7 volts. To calculate the voltage of a LiPo pack, multiply 3.7 volts by the number of cells. Again, the number S number tells you the number of cells.
The lower nominal voltage makes 2S LiPos a good fit for lightweight models where longer run times are desired. Typical uses include: The lower maximum current draw also suits 2S batteries to powering electronics like FPV video transmitters and receivers. For low-power devices, a 2S LiPo offers plenty of runtime.
It depends on the ESC (Electronic speed control) whether you can use a 3s battery on it or not. If the ESC is rated to run 2 to 4S, then you can use 2s, 3s, or 4s battery with that ESC. But if the ESC is rated 2S, then do not use more than a 2s battery on that ESC. What Is the Difference Between 2S 3S 4S Li Po Batteries?
As lipo 2s batteries have a lower voltage than 3s batteries, the motor speed for 2s batteries is also lower than 3s batteries. The motor speed for the lipo 2s battery is 31080RPM and for the lipo 3s battery is 46620RMP for a 4200kv motor. Here is the chart of total voltage according to the capacity.
To answer this question, you have to factor in battery's capacity into the equation. So a 3S 2200mAh LiPo will be heavier than a similar 2S 2200 mAh pack. So, If your shopping for a battery pack for your RC car, a 3S pack will be heavier than a 2S pack. Is a 2S or 3S LiPo more powerful?

For 1 there is a reason lithium cells require a BMS to be used safely. The biggest glaring issue with this answer is it fails to mention that not having a BMS on any additional batteries running in paraellel will fail to keep the non BMS batteries in balance. Which will cause them to degrade quicker.
