COMMENTS: In addition to NiMH batteries, Lithium batteries can be used to
power both power systems of the Siren ARF. Using Lithium batteries
will increase your flight times substantially while decreasing the
final weight of the model slightly. The following are the
recommended Lithium batteries for the Siren ARF.

Brushed Sport Package
This power system requires two 7.4V 1500 mAh batteries wired in
parallel for a 2S-2P configuration. Required for this is:
Two Great Planes Lithium-Polymer packs - GPMP0830
Two W.S. Deans 2-Pin Ultra Plugs - WSDM3001
One W.S. Deans Wet Noodle Flex Wire - WSDC1410

Brushless Option One
This power system requires two 11.1V 1500mAh LiPo batteries
wired in parallel for a 3S-2P configuration. This configuration
will diliver slightly less performane than the 10-cell NiMH pack,
but the run time will be increased to 5-6 minutes. Required is:
Two Great Planes LiPo 1500mAh 11.1V 3-cell pack - GPMP0831
Two W.S. Deans 2-Pin Ultra Plugs - WSDM3001
One W.S. Deans Wet Noodle Wire - WSDC1410

Brushless option 2
Four 7.4V 1500mAh LiPo batteries wired in series and parallel
for a 4S-2P configuration. This configuration will deliver the
highest performance and 4-5 minutes of run time. Required is:
Four Great Planes LiPo 1500mAh 7.4V 2-cell packs - GPMP0830
Four W.S. Deans 2-Pin Ultra Plugs - WSDM3001
One W.S. Deans Wet Noodle Flex Wire - WSDC1410
