Battery Charging
This lithium polymer battery pack is equipped with an internal cell balancing circuit that allows
the battery to be charged from standard RC battery chargers. Charge the battery by
connecting the barrel connector via the supplied adapter cable and setting the charger for
7.4V, 1000mAh Li-Po, 1A (1C). Some RC chargers require a balance lead connector to be
connected to the charger, or else the charging attempt will result in an error.
The balance
lead on the battery is not a true balance lead and is only used for powering the
optional fan faceplate.
To charge this battery set your LiPo charger to Fast Charge mode,
which usually disables the balance lead requirement (set at 7.4V – 2cell - maximum 1A). On
some LiPo chargers none of the above procedures will work. In that case you can set the RC
charger to NiMH mode and set max charge rate to 1A (1C).
Note (1):
In NiMH mode the charger may fail to announce completing the charge. You should
be able to estimate your battery charge amount by either timing (a fully depleted battery will
charge in 1 hour at 1C) or monitoring the mA charge rate on the RC charger display (will drop
to almost zero as it becomes full). Remember, you can always remove the battery from the
charger and depress the battery level indicator button to check the charge level.
Note (2):
If battery becomes fully discharged or shorted, an internal safety circuit will trip. To
reset the battery, tap 9V direct to the barrel connector via the discharge adapter cable’s
banana connector. This will instantly reset the battery and it can be recharged as normal.
General Lithium Polymer safety and handling instructions:
• NEVER balance charge this LiPo battery.
• NEVER leave a LiPo battery unattended while being charged or discharged.
• ALWAYS monitor the battery and charger during the entire charging process.
• ALWAYS charge LiPo batteries in a fireproof location.
• ALWAYS have a lithium approved “class D type” fire extinguisher available.
• NEVER charge LiPo batteries at currents greater than the “1C” rating of the
battery (“C” equals the rated capacity of the battery).
• NEVER continue to charge LiPo batteries if the charger fails to recognize full
charge. Overheating or swelling of the LiPo cells is an indication of a problem and
the battery should be disconnected from the charger immediately and placed in a
fireproof location
• ALWAYS discontinue charging or discharging a LiPo immediately if at any time
you see smoke or the battery starting to swell up and leave it in a safe fireproof
location for approximately 30 minutes.
