• Ensure that the battery does not overheat during use, recharging, discharging, transport or storage. Do
not place rechargeable batteries next to sources of heat (e.g. a speed controller or motor) or expose
them to direct sunlight. This may cause the battery to overheat, which can cause a fire or explosion!
The temperature of the battery must not exceed +60 °C. (If necessary follow additional manufacturer
specifications for the battery!).
• If there are any signs of damage or the outer casing starts to swell or expand, discontinue use immedi-
ately. Do not charge it any more. This may cause a fire or explosion!
Exercise caution when handling the damaged battery and use suitable protective gloves. Dispose of the
battery in an environmentally friendly manner.
Never store such batteries in an apartment or in a house/garage. Damaged or swollen lithium batteries
may suddenly catch fire.
• Always use a compatible charger to charge lithium batteries and/or always use the suitable charging
method. Do not use NiCd, NiMH or lead-acid battery chargers, as these may cause a fire or explosion!
Always select the correct charging method for your rechargeable battery.
• Always use a balancer when charging a lithium battery with more than one cell (the included battery
charger comes with a built-in balancer).
• The charge rate for LiPo batteries must not exceed 1 C (or the value stated in the battery instructions).
This means that the charging current must not exceed the battery capacity (e.g. battery capacity =
1000 mAh, max. charging current = 1000 mA = 1 A).
• The discharge current must not exceed the value stated on the battery.
For example, if "20 C" is printed on the LiPo battery, the maximum discharge current is 20 times the
battery's capacity (e.g. battery capacity = 1000 mAh, max. discharge current = 20 C = 20x 1000 mA =
20 A).
Exceeding the maximum current may cause the battery to overheat or become deformed, which can
lead to a fire or explosion!
However, the printed value (e.g. 20 C) generally does not indicate the continuous current but the
maximum current that the battery can deliver for a short period. The continuous current should not be
higher than one half of the stated value.
• Do not allow the individual cells of a lithium battery to become fully discharged. Overdischarging of a
lithium battery may destroy the battery or cause permanent damage.
If the model does not have overdischarge protection or a low battery indicator, stop using it before the
battery becomes empty.
