We are very pleased to be able to offer you these new ultra High performance Duralite
Evo 20 Li-Poly batteries as they are the best we have seen. They will easily power the
bigger models and helicopters and give long life and incredible output. Also these battery
packs are perfect for many electric sailplanes as the current output is incredible! The
size is perfect for the narrow fuselages so common with electric sailplanes. Try the 3700,
or the 5000 series for any 3 meter sailplane for incredibly long flight times. The high
discharge rates also means much lower resistance. What this means to you the modeler is
steadier, higher voltage even at full throttle and heavier loads. This results in quicker
response, more power and longer flight times. The average load will be well within the
specs of the battery meaning more recharges and longer life to the battery packs.
While the 3700 series is perfect for most any airplane as it will provide good flight
times and low weight. We suggest using the 3-5 cell 3700 in any of the Accord, Samba, or
Vermont Belle airplanes. This series will also fit in many of the 3 meter sailplanes are
are a good match in size and weight. The 3700 series is also perfect for any helis such as
the Swift, or Logos.
The 5000 and 6600 series are excellent for many of the larger airplanes will provide
phenomenal power. You can power a Samba with the 3s2p 5000 mah pack and you can go up to
1/4 or 1/3 scale for the 6s 3P packs! The 5S and 6S packs are perfect for the Logo and
Swift Helis. The ability to demand such high current will give outstanding climb power and
no bogging. The Evo 20 packs clearly blow away the competition.
Here are the outstanding features:
- 20C constant and 30C burst capabilities bring more power to all types of model.
- Exceptional voltage held under load (3.5V under 10C load) gives more all round power to
weight ratios than ever before.
- Wired for easy connection to DURALITE Stay Balance ModuleTM
for a completely integrated state of the art cell balancing system unlike anything on the
market today.
- Use with correctly specified Li-poly chargers that recognize cell count. (Examples:
Orbit Microlader Pro, Schulze, Sirius Charge Lithium and Astro Flight Lithium Chargers)
- 14GA wire-no connectors, w/Stay Balance Module Rainbow Ribbon connection
- Compatible with #90-2/6 Stay Balance Module
