If you are using Li-Po batteries it is critical that you use a
battery charger designed specifically for this type of battery.
Other types of chargers will not work properly and could
cause the battery to be overcharged, causing it to swell,
overheat and rupture – possibly causing a fire if the battery
is being charged near combustible material. If the battery
becomes even warm, disconnect it immediately. NEVER
charge a Li-Po pack unattended. The Great Planes Triton
™
charger (GPMM3150) is a suitable charger for Li-Po
batteries.
Warning: Even with the proper charger, the
risk of a fire is much higher with Li-Po batteries, so
always charge these batteries away from combustible
materials and carefully monitor the charge process.
Proper charging of Lithium batteries is very important.
Consult your charger for charge procedures and for
precautions to observe. At a minimum these should include:
1.
If the battery becomes damaged, as in a model crash,
immediately remove the battery and place it in a remote
area away from combustible materials. Monitor the
battery for at least 20 minutes. If the battery remains
cool, it is safe to transport. If the battery is physically
damaged, it should be disposed of.
2. If a soft sided battery, such as a Li-Po, is dented even
slightly it should be treated as a damaged battery and
immediately isolated as above.
3. Wear safety glasses when handling damaged batteries.
4. When charging lithium batteries, use a Protective
Charge Module that monitors individual cell voltage.
5. Whenever you charge a Lithium battery, ensure that the
charger is set to the correct number of cells. Double
check the setting, then triple check it!
6. Do not charge a Lithium battery while it is installed
inside a model.
7. Charge batteries in a well ventilated area.
8. Charge batteries away from combustible materials.
9. Charge batteries in an area with smoke and fire detectors.
10. Do not charge a Lithium battery at a rate higher than 1C.
11. Use a charger specifically designed for the type of
battery being charged.
12. Do not charge any battery inside a vehicle.
13. Do not wear jewelry or watches when working
with batteries.
14. Do not put batteries in your pocket.
15. Never charge batteries unattended.
The best type of charger for NiMH and NiCd batteries is a
peak charger, because it charges the batteries until they are
fully charged, then automatically switches to a trickle
charge mode. The Great Planes ElectriFly Peak Charger
(GPMM3000) is suitable for NiMH and NiCd batteries as
well as transmitter battery packs. The Great Planes Triton
charger (GPMM3150) is also suitable.
The following applies to NiMH and NiCd batteries only:
If you have another type of charger that is not a peak
charger, you will have to calculate the length of time it takes
to charge the batteries yourself, then turn the charger off
when the batteries are fully charged. Overcharging the
batteries may damage them. Before you can calculate the
time it takes to charge a battery pack, you first have to know
the charge rate you are going to use. Nickel-metal hydrides
should be charged at a rate of no more than 1/10 of their
capacity. For the 650 mAh batteries recommended for the
RV-4 Park Flyer, this would be a charge rate of
approximately 65 mAh. Divide the capacity of the battery
pack by the charge rate to calculate the charge time. A
discharged 650 mAh battery pack charged at 65 mAh will
take 10 hours to charge.
Charge rate/time recommendations for a fully
discharged pack:
•
Charge a 650 mAh battery pack at 65 mAh for 10 hours.
• Charge a 1050 mAh battery pack at 100 mAh for 11 hours.
IMPORTANT: Monitor the temperature of the battery
frequently. If the battery becomes warm, disconnect it from
the charger.
Note: The period required to charge the batteries in the
examples above is for discharged batteries. If the battery
you are going to charge is not discharged (and you are not
using a peak charger), connect it to the motor on your
model. Run the motor until the propeller is turning slowly,
thus discharging the battery.
There are several types of covering that may be used on the
RV-4 Park Flyer, and a few that are not recommended. Use
a covering suitable for lightweight models. Top Flite
