Drone battery knowledge is divided into several main aspects, one is the battery type, one is the battery parameters, and another is the battery out of the interface; understanding these basics will allow you to quickly choose the right battery.

Drone battery with intelligent protection board

1, drone battery wire plug introduction

Drone battery wire and plug has a variety of specifications models, mainly according to the size of the battery discharge to do with, while the wire size but there are certain standard rules, the more common wire specifications are 8/10/12/14/18/20/22AWG, etc., as for the use of the plug type and shape on more, mainly according to the actual discharge, such as the common points XT60 and T interface. recommended XT60XT60, generally rated at 60A, T-type just like his name, looks like T-type, generally rated at 20A, etc.;

2, drone battery type

The main types of batteries used in drones are nickel-metal hydride batteries, steel-cased cylindrical lithium-ion batteries, lithium polymer batteries, lithium iron phosphate batteries (steel-cased, aluminum-cased or soft pack) these, the specific use of what battery, depending on what type of drone or players like to use what battery. For example, some model aircraft do not require high battery weight, discharge current requirements are not high, many players use may be cylindrical 18650 lithium batteries, or NiMH batteries may also be, but no matter what, most of the batteries used in drones are now soft pack lithium polymer batteries.

Because this type of battery light weight, high energy density, capacity, and support for high current discharge, can allow players to well experience the thrill and joy of high-speed drone flight performance.

3, drone battery parameters

Drone battery parameters mainly include capacity size, voltage size, discharge current size and several cells in series and parallel connection of these, these aspects of the data represent a clear meaning, not only good help to their own choice of battery, and if you can diy drones, then the choice of battery will be more like a fish in water.
Let's take a look at the following drone battery label on all the labeled content:

Drone battery without smart protection board

355.2WH is the total power of this battery with full charge, that is, if the total power of your model motor according to 355.2W stable flight, you can fly an hour, but in fact we play the average power of the model will be larger than this power, so the general flight time will be within 1 hour, if it is explosive flight, that is, continuous high-speed flight, may be a few minutes to run out of power This still depends on the power of the maximum flight is how big it.

Battery for aerial photography drone

16000mAh is the capacity of this battery, if we say that according to the overall discharge current size of the model, if the model motor work maximum current 270A, minimum working current 16A, average flight 40A, then the approximate working time of this battery is 0.4 hours, that is, about 24 minutes.
The 4S in 6S1P means that this battery is made of 6 cells in series, and 1P means that there is no parallel connection of cells. Together, it means that this battery is a pack of 4 cells connected in series in a single row.

25.2V is the full charge voltage of this battery when fully charged, because the full charge voltage of a single lithium cell is generally 4.2V, 4.2V x 4 = 16.8V;
The above is an example of tattu drone battery label above the numbers and letters represent the meaning, in fact, many model batteries brand above the numbers and letters represent the meaning of basically the same.

It should be pointed out here that the pursuit of model batteries is high battery capacity, can support high current discharge, while the smaller the volume and weight the better, currently able to meet these conditions, the better choice is the high rate of lithium polymer battery type.
