LiPo packs are manufactured in a state of the art facilty in Malaysia
using the highest quality Lithium Polymer cells produced exclusively
by Enerland of Korea. The continued in-house development of lithium
polymer chemistry has allowed even more performance from LiPo
brings a fully rounded product lineup taking advantage of improvements
in technology and a wealth of experience. This provides you with
the best selection for your application based on cost, weight,
and performance. The following products below will be summarized
to help you decide which one is best for your application.
EVO F3A Competition
has created several series of Lithium Polymer packs, each with
different formulations, to provide a wide range of choices to
the customer. One of these series below is bound to be well-suited
for your application.
capacities from 350mAh up to 5350mAh, the EVO LITE series
are lighter in weight and lower in cost per unit capacity. All
of the packs deliver an 18/28C performance, except the 5350mAh
pack which is a 17/28C product.
EVO LITE pack is designed for tiny foamies, park flyers,
.50-size conversions, and two-meter aerobatic aircraft where
weight and flight duration are major factors in flyingperformance.
Notable members of this group include a well proportioned 1320mAh
pack, and an 800mAh pack that fits the Blade. A 2500mAh pack
that fits the T-Rex and .30-size Katana.
EVOF3A 5350 Competition is the flagship of this group
- a matched 10s pair of two 5s packs with super lightweight
construction is rapidly proving to be the 2007 pack of choice
for International F3A competitors. Fast charge rates up to 2C
are approved in conjunction with balancing.
EVO 25 V-Power series provides an optimum balance of
weight and power for helis and acrobatic aircraft. The series
has a wide range of capacities from 1200mAh to 5000mAh. The
1200-1800mAh capacities boast a 25/40C discharge rate and a
25/50C rate for the 2170-5000mAh group.
V-Power series is a stunning improvement on the
previous generation's already excellent EVO 20 and EVO 20NF
products. This series has more reliable capacity with lower
temperatures and truly sparkling performance. 600e sized helis
have been transformed by EVO 25 making 6s setups a completely
members of this group are the outstandingly popular 2170mAh
3s and the 5000mAh 6s packs for the T-Rex 600. The 3700mAh 10s
sticks for the Mikado Logo and Raptor 620e machines are also
very popular. For power hungry F3A competitors, there is a 5000mAh
10s F3A Competition pack with super light weight construction.
Fast charging rates up to 2.5C are approved in conjunction with
EVO 30 Premium series has pack capacities from 700mAh
to 4500mAh. These are premium cells with increased weight and
cost per unit capacity for applications where only power
EVO 30 Premium products deliver a whopping 30/60C rate.
EVO 30 is designed primarily for EDF projects, .90-size
3D competition helis, and F5B where flight time is less of a
consideration than raw power and reliability under extreme load
counts for everything. Fast charge rates up to 3.0C are approved
in conjunction with balancing.
F3A COMPETITION setup is a high power configuration consisting
of a single 10s 5000mAh block that can deliver 25C continuous
current and 50C burst. It is ideally matched to large high current
draw Plettenberg, EVO, and CYCLON outrunners with 22x12 props.
light weight F3A COMPETITION setup uses two cell-matched
5s 5350mAh blocks that can deliver 17C constant current and
up to 28C bursts. This setup is ideally matched to Hacker C50
14X XL motors with a 22x12 prop. Rear link leads are provided
for convenient arming and disarming.
FlightPower V-Balance Module is an intelligent hi-rate equalizing
balancing system for 2s-6s packs. The V-Balance system is a
charge-through balancer that will work with all Lithium-Polymer
chargers and FlightPower packs by connecting between the charger
and the battery. This system features LED's for each cell to
indicate balancing activity, a battery capacity fuel gauge and
the capability of handling charge currents of upto 10A for 2C
charging of large FlightPower packs. V-Balance boasts many more
features including individual cell analysis and discharge features.
has a wide range of leads for connecting new or original FlightPower
packs to the new V-Balance. Also note that FlightPower packs
are compatible with ThunderPower balancers and chargers.
Preparation and Testing:
My FlightPower EVO25 5-cell 5AH packs arrived in plastic bags,
each containing a sheet describing safety information and handling
precautions. I soldered on my favorite Dean's Ultra connectors
and tested the fit in my Hangar 9 150-size P-51D before attaching
Velcro. The 23oz packs fit perfectly and the two 5-cell packs
in series (10s total) can easily provide the 3000 watts needed
for my application.
goal for my P-51D electric conversion project was to have a full
throttle current between 80-90 amps. This would allow the P-51
to provide bursts of about 3000 watts with a 10-cell LiPo voltage
for some impressive fly-bys. The 25C 5000mAh FlightPower EVO25
pack can deliver 125 amps continuous and double that for short
bursts. LiPo savvy users know that by not pushing the limits
of the pack current ratings or capacity, over 300 pack cycles
can be obtained.
full throttle, the power system measured 3300 watts at 100amps
using the two 5-cell packs in series (10s total). This provided
the P-51D with a fantastic power level around 200w/lb at an
all up weight of 16lbs.
Charging and Compatibility
packs are compatible with ThunderPower node connectors so your
existing LiPo charger may be all you need for safely charging
the packs. In the photo above, the FMA BalancePro 6s charger uses
the ThunderPower/PolyQuest adapter to safely charge and automatically
balance each cell in my 5s 5000mAh pack.
images on the right show various screens and the charging graph
from my BalancePro 6s software while charging the 5s 5000mAh FlightPower
pack. Note on the bottom graph, the FlightPower packs are shipped
at half charge (or 3.8v) and that all 5 cells follow the same
curve. This is an indication of a healty pack.
V-Balancer with Complete Lead Set offers a range of leads for
connecting original FlightPower packs and new FlightPower packs
(with the Highrate V-Balance connectors) Also, for connecting
new 3s FlightPower packs (with the new Highrate V-Balance connectors)
to the original 2-6s Staybalance module, the "Highrate 3s
- Classic 3s Adaptor" can be used, which will then have to
be plugged into the conventional 3s adaptor lead.
FlightPower V-Balancer uses alternating green and amber lights
next to the printed cell numbers 1 through 6 for visibility. It
stops the light from one channel appearing in the next channel.
There is no difference in meaning between the green colored light
and the amber colored light. By using the FlightPower V-Balancer
in-line with your existing Lithium charger, the pack stays healty
since all the cells are balanced during the charge cycle.
Dual V-Balancers Balance a 12s Pack
V-Balancer can safely charge and balance up to a 6s (or 6 cell)
pack. By connecting two V-Balancers in series, you can safely
charge huge packs up to a 12s configuration. For detailed information
on connecting several V-Balancers together to charge up to a 12
LiPo pack, visit the www.flightpowerusa.com
