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 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.

Weight

A 25c 2000mah Lipo battery can weigh from 170 grams to 270 grams. When you look
to buy a battery, weight should be one of the thins you look at. Some 1600mah
batteries weigh as much as some 2200mah batteries. A batteris has a huge effect
on the planes power to weight ratio. Two extra ounces will make a big
difference in your planes performance.

Physical Size of TTF Longest Lasting Drone Battery

For a battery to be right for your model it must fit within the model’s
battery compartment. Not all batteries are the same size. While most
manufacturers try to stay consistent in sizing, the dimensions can still be
quite a bit different. Sometimes a 2mm difference in size might keep it from
fitting in your model.

Discharge (C)

Discharge is the amount of power the battery can supply your power system. The
‘C’ rating is an multiplication of the capacity. Example: A 20C battery can
discharge at 20 x 2,000mAh which is 40,000mAh or 40Amps. This is an important
number to consider. It’s always good to use a wattmeter to measure the demand
of your system. The millamp hours divided by 1000, times the C rating, equals
the maximum continuous discharge amperage the battery is capable of sustaining.
That’s mah/1000 x C = Amps. So 2200mah/1000 x 25C = 55Amps.

The Charge Rate

Some batteries will display a ‘C’ rating for charging. MOST batteries are
rated at a 1C charge rate. The formula is this:
XXXX mAh / 1000 x (Charging C rating) = XX amps
For example: If you had a 2200mAh LiPo pack with a charge rating of 2C you
would not want to charge the battery at rate more than 4.4 amps.
It’s the lower amperage you charge your batteries, the longer they will take
to charge. However, a slower charge is always better for the health of your
battery. If you have the time… take it slow. If you can’t find charge rating
on your battery, then play it safe and charge at 1C.

Hard or soft?

Normally LiPo batteries come in two different forms: as soldered packs wrapped
in shrink wrap or as so called hardcase packs that feature an outer plastic box
to protect the cells.

If you just bash or race non-sanctioned races softcase (shrink-wrapped) packs
are ok as long as you make sure that there is no possibility to damage them
during use. Damage can be done by rocks, stones, wood and basically everything
that you can find off-road. In this case hardcase packs are the way to go. When
your model is equipped with an enclosed diy drone battery compartment shrink-
wrapped are ok too.
