VOLTCRAFT 1209050 Notice D'emploi page 44

• If the battery is damaged (e.g. after an airplane or helicopter model crashes) or
the exterior shell is inflated/swollen, do not continue to use the battery. Do not
recharge it. There is a risk of fire and explosion!
Handle the battery with care, use suitable protective gloves. Dispose of the
battery in an ecologically sound fashion.
• Only use a suitable charger to charge lithium batteries or use the correct charging
procedure. Due to a risk of fire and explosion, conventional chargers for NiCd,
NiMH and lead acid batteries may not be used!
• When charging a lithium battery with more than one cell, always use a so-called
"balancer" (one is already integrated into the supplied charger).
Charge LiPo batteries with a max. charge current of 1 C (if not indicated
otherwise by the battery manufacturer!). This means that the charge current may
not exceed the capacity value imprinted on the battery (e.g. battery capacity 1000
mAh, max. charge current 1000 mA = 1 A).
With LiFe or LiIon batteries, you must observe the instructions of the battery
manufacturer.
• The discharge current must not exceed the value displayed on the battery.
For example, if a value of "20 C" is printed on the battery, the max. discharge
current is 20 times the battery's capacity (e.g. battery capacity 1000 mAh, max.
discharge current 20 C = 20 x 1000 mA = 20 A).
If these guidelines are not adhered to, the battery will overheat, which will lead to
the battery becoming deformed/swollen or result in an explosion and fire!
The printed value (e.g. "20 C") does not generally refer to the constant current,
but to the maximum current that the battery is capable of producing in the short-
term. The constant current should not be higher than one half of the given value.
• No cell of a LiPo battery may be discharged below 3.0 V (LiFe = 2.0 V, LiIon =
2.5 V), as this will destroy the battery.
If the model does not provide protection against total discharge or possess a
visual display indicating a low battery, remember to switch off the model in time.
