Thank you for purchasing your Lipo pack from Airtek Hobbies. Lipo batteries outperform previous battery technology such as
Ni-Cd and Ni-MH by a significant margin in terms of capacity, voltage and weight. The downside to these performance gains
are that lipo batteries require special handling and care. When following these guidelines you can expect safe and reliable
performance from your battery pack.
PLEASE THOROUGHLY READ THE FOLLOWING INSTRUCTIONS BEFORE USING YOUR BATTERY PACK FOR THE FIRST TIME.
• Never leave your battery unattended whilst charging is taking place and charge in a fireproof location. Lipo batteries have
been known to spontaneously combust so must be attended at all times during charging.
• Always charge your lipo in a fireproof bag. They are inexpensive and can contain a fire should one occur.
• Always remove your battery from the model during charging. A hot pack could ignite foam plastic or wood.
• Never trickle charge your Lipo Pack.
• If your battery exceeds 140ºF/60ºC during charging it is possible that it has been previously damaged. Terminate the
charging process immediately and dispose of the battery pack.
• If you see any smoke or swelling of the pack during the charging pack terminate charging immediately. The chemicals
used in a Lipo pack, if leaked may ignite upon exposure to the air. Remove the battery pack to a safe place and leave for 60
minutes.,
• If you crash your model check the battery for damage. It may appear to have no physical damage but there may be a
delayed chemical reaction internally which could cause a fire. Remove to a safe fire proof location and leave for 24 hours.
• Do not allow the batteries electrolyte to get into your eyes or on your skin. Wash affected areas immediately and seek
medical attention.
• Always transport your Lipos in a fireproof bag or container and do not leave in a hot car.
• Always store your Lipos in a fireproof bag or container in a temperature of between 40º to 75º F out of direct sunlight and
away from any liquids. Make sure all plugs and connectors are adequately covered to prevent accidental shorting.
• Never carry your Lipo pack in your pocket or clothing.
• Never modify, disassemble or puncture your Lipo pack.
NOW PLEASE READ THE USAGE INSTRUCTIONS BELOW
• Charge your battery using a charger specifically designed for the charging of lithium polymer batteries. If your charger is
capable of charging other types of battery always ensure it is set to Lipo mode. NEVER EVER use a charger designed for Ni-
CD/Ni-Mh batteries.
CHARGER SETTINGS FOR LIPOS DESIGNED FOR MAXIMUM OF 1C CHARGE ONLY
If your Lipo Pack is marked at 1C maximum charge rate DO NOT ATTEMPT TO CHARGE AT A FASTER RATING. As an example,
for a 3 Cell 2200mah battery set the cell count on your charger to 3 cell (some chargers will auto detect) and the charge
rate at 2.2amps, for a 2 cell 500mAh battery set your charger to 2 cell and your charge rate to 0.5amps i.e take the mAh
rating of your battery and divide by 1,000 to find the charge amperage rate. Therefore an 1800mAh battery is charged at
1.8amp, a 1300mAh battery is charged at 1.3amp etc.
CHARGER SETTINGS FOR LIPOS DESIGNED FOR UP TO 5C CHARGE
As battery technology improves many packs (particularly the Kypom Packs) are capable of charge rates of up to 5C.
This considerably reduces the charging times which for many modellers provides greater convenience and flying time.
However, the downside of using high C ratings is that battery life will be reduced. We would reccomend a compromise of
1c Charge in your workshop and fast charging on the field. A charge rate of 2 or 3c is a good compromise. As an example to
charge a 1200 mAh cell at 5c you would set your charge rate to 6amps (i.e. 5 x the 1c rate of 1.2 amps). To charge the same
pack at 3c you would set your charge rate at 3.6amps (3 x the 1c rate of 1.2 amps). Irrespective of the C rating you charge
your pack at the mAh setting on your charger should remain the same - i.e. a 1200mAh pack should be set at 1200mAh,
only the C rating (amps) change when you fast charge.
It must also be noted that charging lipos at higher C ratings requires a charger with a suitable output. Many budget
chargers of around 50A may only allow a 2c charge rate.
