All About Multirotor FPV Drone Battery Chargers

FPV racing and freestyle drones are power-hungry machines! At a minimum
there are 4 high-speed motors driving propellers at thousands of revolutions
per minute (RPM). The power systems on the drones operate at voltages ranging
from 4.2 volts (v) for the micro drones, to 25 v for the high-powered mini quads.
Volts are important, but amperage makes power! The motors on the racing and
freestyle drones pull upwards of 25 amps each, multiplied times 4 motors and
we have a 210mm drone capable of using upwards of 100 amps in a high-speed
punchout! This kind of speed requires a special set of requirements.
Currently, the battery of choice is the lithium polymer battery, called a "LiPo".
us minutes of flight time. These batteries are also rechargeable,
and thus the FPV Drone battery charger is a key component to your FPV arsenal!

Charging Batteries:
The FPV Drone Battery Charger we use is a smart piece of technology.
|Using microprocessor controlled circuitry, this FPV Drone Battery Charger
monitor the battery of the LiPo battery. Most modern drone battery chargers
are capable of charging a variety of voltage. Goggle batteries for example
may require 8.4v while drone batteries may require 16.8 v and above.
Drone battery chargers should be available for a variety of user-selectable
voltages. That way a drone pilot can use a single charger for all his batteries,
from the radio transmitter battery, fpv video receiver battery goggle battery
and batteries for many different types of drones.

Balance Charging and Battery Types:
For drone battery safety, it is crucial that the batteries have their individual
cells "balanced," meaning the charger will adjust, up or down, the voltage of
each cell in a battery so that they match. Modern battery chargers will have
"balance" ports so that the batteries can be balanced. While on the market, you
can use multiple types of batteries in addition to the LiPo. For example, most
chargers are also capable of charging lead-acid batteries like what is in your
car, or NiCd batteries for other uses. The control circuitry can be adjusted with
the voltage and charge rate. This makes battery chargers useful tools around
the home workbench as well.

Field Charging your Batteries:
Nobody likes to wait for their batteries while their friends are flying without them.
This can be prevented by having a large number of batteries. 2) charge multiple
batteries at the same time. Todays battery chargers can often use many sources or
input power from alternating current (AC) in your home, to the direct current (DC).
Furthermore, it is important to note that your battery charger has a built in AC / DC
converter, so that it can be plugged in to your wall outlet at home directly. Without it,
some battery chargers require an external AC / DC converter. Many battery chargers
have multiple outputs, so that they can be charged separately. Using a battery charger
with the ability to utilize the DC input which also has multiple outputs in the field.
This can be a great advantage when the race is a hero off the beating path, or there
are no available outlets. It is also cost effective, if you have a full day of flying!

Conclusion:
An FPV Drone Battery Charger is a crucial component of the drone hobbyist's
collection. They are versatile enough to charge just about any type, size, and
voltage battery you may have. They are also a key component or drone power
system safety. LiPo batteries, while safe, can present a danger in the fire,
especially when incorrectly used. Modern battery chargers utilize smart
programming to help your batteries last a long time without damage or danger.
Battery chargers are also becoming miniaturized, with some units ready to fit
in the palm of your hand! There are many good chargers available, and many
have very similar menu functions, allowing you to select the type of battery,
voltage, battery charge and other battery conditions.

Be sure to charge your LiPo batteries in a fire-resistant LiPo bag,
and never leave a charging battery unattended.
