Drone Battery

The next part of your drone is your esc battery. Modern RC drones use lipo batteries, which have a good power to weight ratio and can discharge a large amount of current very quickly.

Choosing the correct Lipo RC quadcopter battery for your drone involves many factors, and you must first have an idea of the voltage and amp requirements of the motor/prop combination that you intend to use. There are a number of factors to consider when it comes to choosing a battery pack. Before making a purchase, think about these points:

* Voltage

* Capacity

* Weight

* Physical Size

* Connector

* Discharge

* Charging Rate

Lipo DIY Drone Battery Voltage (S)

All Lithium Polymer cells have a nominal voltage of 3.7v per cell. When fully charged a LiPo cell should be 4.2v and when discharged it should never be below 3v. You will notice that LiPo packs are made up of layers of multiple cells. A 1S = 1 cell (3.7v). If the LiPo pack is listed as being 3S this means it is 3 cells x 3.7v (per cell) which is 11.1v (3s 11.1v lipo battery). It has 3 layers of 3.7v each. The rating for each cell is always referenced by its nominal voltage (3.7v), NOT the maximum voltage (4.2v).

Capacity (mAh)

This is usually the biggest or most obvious rating shown on the LiPo pack and is measured in mAh (Milliamp/hour) or Ah(Amp/hour). The capacity is an important factor to consider. Think of capacity (mAh) as the amount of fuel in your car’s fuel tank. A higher capacity tank will run your car for longer. 55 amps is the maximum safe current a motor can draw from this battery.

The mah rating: 2200mAh is 2200 milliamp hours or 2.2 amp hours. That is the amout of energy the battery can hold. This battery will give 2.2 amps of current for one hour. Or 4.4 amps for 1/2 hour, or 8.8 amps for 15 minutes.
