Enerland batteries offer a wide selection of battery
packs for any type of electric aircraft you may have.
motor and through the tail cone. This
patented design actually keeps the motor’s
operating temperature lower than normal
ducted-fan setups that have an external
motor attached to the fan.
HOW EFFICIENT?
The fan unit has a swept area of 3. 87 square
inches and operates on a 3 to 5-cell LiPo
battery, which produces about 54,000rpm
(on 5S) and pushes out a static thrust of up
to 4. 3 pounds. All of this, while only
pulling 100 to 102 amps on a 5-cell pack
and down around 82-84 amps with a 3-4

cell pack. In comparison, some of the best
ducted-fan setups now need about 120 to
125 amps to push out the same static thrust.
Now we have a 70mm ducted-fan unit that
operates in the 1500 to 1900 watt range and
is capable of producing a very large amount
of thrust for its class.
STORED POWER
If you’re looking for some powerful batteries for that electric-powered aircraft, a
one-stop place is Enerland batteries. This
company has a good selection of 30C LiPo
that can produce the power you need for
just about any size electric aircraft. They
provide plenty of power and come in all different sizes. Enerland is also one of the
leading makers of Nanophosphate Lithium
Ion A123 batteries. These are the future of
electric flight for many reasons, but right
now they have limited use in smaller aircraft and are quickly becoming the batteries
ULTIMATEELECTRICS
of choice for helicopters and larger aircraft.
The batteries come in a wide choice of pack
configurations, for just about every need.
The beauty of these batteries is that they
can be charged in about 20 minutes and are
very hardy when compared to LiPo batteries. They can be discharged at a continuous
30C with bursts of up to 60C. There is much
less of a risk of damage and any subsequent
venting (fire) from the batteries. Fast charging and less chance of damage make these
batteries much safer then LiPo packs. Even
the chargers are much easier to use. The
Nanophosphate Mini distributed by Enerland has only one button on it, and is used
to set the current and to start/stop the charging. The charger has a balance plug that
keeps all the cells in balance during charging. These are the batteries of the future and
they’re available now. If you have a larger
aircraft, you’ll want to try these out.
The Nanophosphate Mini charger is very simple to
use and will charge the A123 batteries in less
than 30 minutes.
LOW-TECH INNOVATION
Sometimes a low-tech idea with high-tech material is just what the
doctor ordered. Such is the case with the new Dymond Li-protectors
bags for your LiPo batteries. In the event of a crash, these bags
offer the best possible protection for your aircraft. When an electric
aircraft is involved with a sudden impact with the ground, sometimes the battery pack will get damaged and this may cause a
short, which causes the pack to vent or erupt in flames. Of course,
this destroys anything inside the
plane that may have survived the
original crash.
To prevent this from happening,
Dymond Modelsport now offers two
different size Li-protector bags made
from Nomex, the same material that
protects our firefighters form burns.
This lightweight bag (8g - 1⁄ 3 oz.)
has special Kevlar thread stitching
that will hold up to just about any
impact; even if the battery shorts
out, there will be no open flame as a
result. However, there will be lots of
smoke and the smell that goes
along with it, but all of your onboard equipment will be fine. The
best part, the bag will still be useable for another battery. The Li-Protector is available in two different sizes for batteries up to 5S
4500mAh—stay safe with these bags!
Every day, there are new developments that make it possible for
electrics to go faster, longer and be safer. I can’t wait to see what
we’ll have available to us next year. Enjoy!
