High-Power Series Lithium Polymer (Li-Po) Batteries
Thank you for purchasing an E-flite Lithium Polymer (Li-Po) battery. E-flite Li-Po batteries offer an excellent blend of weight, power and performance. However,
like all Li-Po batteries, they require proper handling and care for safe and maximum performance.
Lithium Polymer batteries come partially charged and are significantly more volatile than the alkaline, Ni-Cd or Ni-MH batteries used in RC
applications. Keep batteries out of reach of children, unless supervised by a responsible adult. All instructions and warnings must be followed
exactly. MISHANDLING OF Li-Po BATTERIES CAN RESULT IN FIRE. For more information, please read the following instructions in their entirety before
handling and using. By handling, charging or using this Li-Po battery, you assume all risks associated with lithium polymer batteries. If you do not
agree with these conditions, return the battery in new, unused condition to the place of purchase immediately.
Handling and Storage Guidelines
1) Li-Po batteries should always be handled with extreme care. Care should be taken to prevent them from being dinged, dented, punctured (especially
by metallic objects such as screwdrivers or hobby knives) or otherwise damaged.
2) Care should be taken to ensure that the battery is never shorted. Even a brief short can cause permanent and catastrophic damage to the battery and
can result in fire. A battery that has been shorted for even just a split second should be placed in an open area away from flammable materials and
observed for at least 15 minutes. It should also be removed from service entirely. To help prevent shorts, it is best to store and transport the battery in a
non-conductive (and preferably fire-proof) container and/or to cover the connectors with a non-conductive material.
3) When temporarily storing or transporting the battery, the temperature range should be from approximately 40–120 degrees Fahrenheit for the best
results. Do not store the battery in a car or direct sunlight whenever possible. If stored in a hot car, the battery can be damaged or even catch fire if the
temperature inside the car becomes too hot.
4) Store the battery at room temperature and approximately 1/2 charge for best results. A Li-Po cell is approximately 50% charged when it is at 3.8V.
The approximate 1/2 charge voltage for a 2S (7.4V nominal) battery is 7.6V The approximate 1/2 charge voltage for a 5S (18.5V nominal) battery is 19.0V
The approximate 1/2 charge voltage for a 3S (11.1V nominal) battery is 11.4V The approximate 1/2 charge voltage for a 6S (22.2V nominal) battery is 22.8V
The approximate 1/2 charge voltage for a 4S (14.8V nominal) battery is 15.2V
Before the First Charge
1) Make a visual and physical inspection of the battery. Look for any damaged or loose leads or connectors, broken shrink tubing or other irregularities which
may cause a short circuit and eventual fire.
2) Check for proper polarity of the factory installed leads and connectors. Use a digital voltmeter to ensure that the polarities are correct.
3) Check the voltage of the battery using a digital voltmeter or the E-flite Power Meter (EFLA110). The voltage of the cells within the battery should be
between 3.5V and 3.9V each.
The voltage of a new 2S (7.4V nominal) battery should be between 7.0V and 7.8V
The voltage of a new 3S (11.1V nominal) battery should be between 10.5V and 11.7V
The voltage of a new 4S (14.8V nominal) battery should be between 14.0V and 15.6V
The voltage of a new 5S (18.5V nominal) battery should be between 17.5V and 19.5V
The voltage of a new 6S (22.2V nominal) battery should be between 21.0V and 23.4V
4) In order to comply with shipping regulations and safety, the 6S 5000mAh battery is equipped with external series wire leads with gold bullet connectors
that are shipped disconnected so the pack is considered as two 11.1V packs connected in series. You are required to connect the series wire leads before
first use by connecting the two bullet connectors in order for this pack to properly operate as a 22.2V pack. Before shipping this pack for any reason in the
future, you will need to disconnect the series leads first.
If any damage or irregularities are found, the polarity of the wire leads or connectors are not correct, or the voltage of the battery is more or less
than the ranges listed above, call 877.504.0233 toll-free to speak to a service technician. DO NOT continue to handle or attempt to use the battery
without further instructions.
Charging Guidelines and Warnings
1) You MUST use a charger specifically designed to charge Li-Po batteries ONLY. The charger must be capable of “constant current / constant voltage”
charging. Failure to use the proper charger may result in a fire causing personal injury and/or property damage. DO NOT use an Ni-Cd or Ni-MH charger
at any time.
2) The battery should always be charged in an open area away from, and not placed on, any flammable materials. The battery should never be charged
inside of the model or a full-size vehicle. It is also suggested that an “ABC” type fire extinguisher be readily accessible in the charging area in case any
issues resulting in fire are experienced.
3) Never charge the battery unattended. When charging the battery, you should always remain in constant observation to monitor the charging process
and react to potential problems that may occur.
