E-Flight has a responsibility as a battery supplier display these warnings for your information, they relate to ALL Lithium Polymer, Lithium Ion (Li-Po, Li-Ion) cells currently available. The fact that a supplier of Lithium Polymer, Lithium Ion does not label or warn of the dangers of their product does not make that product safe.

Under modelling discharge rates, the capacity of rechargeable Lithium packs or cells declines gradually, after 50 cycles it may be as low as 50%-80% of a new pack. E-Flight is unable to ensure that the correct charging regime is applied to this product, once the cells have been charged/discharged we cannot accept any claim under our normal guarantee. Please read these instructions & disclaimer carefully, they will also be supplied with any cells or packs purchased from e-flight, they must also be passed to any new owner should the cells or packs be sold. Misuse of these cells can & will lead to explosions, fire, smoke & risk of poisoning.

Please note Li-Poly battery must be charged with a dedicated Lithium charger. Buyer understands there are risks, known and yet unknown, to the use of Li-Poly battery in RC hobby.

• Only use chargers designed specifically for Lithium Polymer battery.
• Double check the charger, number of cell selection setting, and mAh
before every charge.
• Only charge the batteries on a non-flammable non-conducting surface, such as bare cement floor.
• Do not charge the battery inside the model plane, inside of ones car, home furniture or wood floor/carpet, or anywhere near flammable material.
• Monitor the charging of the battery pack at all times. Do not leave the battery unattended.
• Place a fire alarm above the Li-Poly battery charging location. Follow the fire alarm installation instructions.
• After a crash, inspect the battery pack for damage. Discard the pack outdoors if there is any sign of damage.
• Store the pack fully charged in a cool and dry location and out of reach of children.
• Do not assemble packs in series into parallel packs, as mismatch could result in fire.
• Do not carry or leave Lithium Polymer/Ion with model fuels such as Petrol/Gas or Methanol
• Do not store Lithium Polymer battery inside a car.
• Do not short the battery as it may catch on fire. If you accidentally short a battery, place it in open space and observe the battery for 10 minutes. It may swell up and possibly even catch on fire.
• Do not discharge Lithium Polymer battery below voltage according to the number of cells in series in the following chart.

Before charging, your Lithium Polymer should have this minimum voltage. Check battery pack voltage before charging S = Series, P = Parallel

Minimum voltage
1 Cell 1SXP = 3.0V
2 Cells in series 2SXP = 6.0V
3 Cells in series 3SXP = 9.0V
4 Cells in series 4SXP = 12.0V


Check your charger for safety. After charging, check battery with a digital voltmeter, voltage should read between Min and Max:

Full charged pack should voltage between these numbers:

Minimum full charge to Maximum full charge
1 Cell = 4.16V to 4.23V
2 Cells in series = 8.32V to 8.45V
3 Cells in series = 12.48V to 12.68V
4 Cells in series = 16.64V to 16.9v


Maximum discharge: Do not discharge your Lithium Polymer battery below the voltage listed below, no load and load voltage. Max Discharge Voltage for Li-poly cells and packs

No Load (Motor not running)/Loaded (Motor running)
1 Cell = 3.0V/2.5V
2 Cells in series = 6.0V/5.0V
3 Cells in series = 9.0V/7.5V
4 Cells in series = 12.0V/10.0V


There may be a slight chance the battery pack could combust due to unmatched cells in capacity or voltage, damaged cells, charger failure, charger setting errors or many other factors. By purchasing these products, buyer understands the risk associated with the use of this experimental product, and will take the necessary precaution for its safe use and hold the manufacturer, seller, all affiliates and agents harmless in case of damage, injury or death. Buyer is solely responsible for any damage or injury resulting from the use of this experimental product. There is no warranty implied or expressed on Lithium Polymer battery and packs, as the intended use of these batteries in RC airplane application is beyond the design specification of the manufacturer. By purchasing Lithium Polymer battery products, buyer fully understands the delicate nature of this battery and risk associated with this product, and agrees with the terms and conditions listed above.
