e) Handling Rechargeable Lithium Batteries
• Modern batteries with lithium technology do not only have a clearly higher
capacity than NiMH or NiCd rechargeable battery packs but they also have a
considerably lower weight. This makes this type of battery very interesting for
application in model construction; so-called LiPo batteries (lithium-polymer) are
often used here.
LiPo batteries (and the LiFe batteries that can be charged with the device) do
require special care however during charging/discharging as well as when being
operated and handled.
• The exterior cover of a LiPo battery, consisting solely of a very thick film, is
extremely sensitive. Never destroy or damage the battery, never let the battery
fall and do not pierce the battery with any objects! Avoid any mechanical strain on
the battery; never pull the connection cables of the battery! There is a risk of fire
and explosion!
These guidelines must also be observed when the battery is inserted into the
model (or removed from the model).
• Ensure that the battery does not overheat during usage, recharging, discharging,
transport or storage. Do not place the battery next to sources of heat (e.g. speed
controller, motor), keep the battery away from direct sunlight. There is a risk of
fire and explosion if the battery overheats!
• The battery must never heat up to more than +60 °C (observe any additional
information from the manufacturer with further limitations!).
• If the battery is damaged (e.g. after the crash of an aircraft or helicopter model)
or the exterior cover is soaked/has expanded, do not use the battery. Do not
charge it anymore. There is a risk of fire and explosion!
Handle the battery with care, use suitable protective gloves.
Dispose of the rechargeable battery environmentally compatibly.
• Only use a suitable charger to charge lithium batteries. Due to a risk of fire and
explosion, conventional chargers for NiCd, NiMH and lead acid batteries must 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).
