• Do not charge batteries when they are still hot (e.g. due to a high discharge current in the model). Allow
the battery to cool down to room temperature before charging it.

LiPo rechargeable batteries usually retain their charge for several months. However, if the batteries
overdischarge, this will result in permanent damage and render them useless.
b) Additional information about lithium rechargeable batteries
ModernlithiumrechargeablebatterieshaveasignicantlyhighercapacitythanNiMHandNiCdbat-
teries and are more lightweight. This makes lithium batteries (especially lithium polymer batteries)
particularly suitable for use in model making.
However, lithium batteries require particular care to ensure safe charging/discharging, operation
and handling.
The following section provides an overview of the potential hazards associated with lithium batter-
ies and explains how these hazards can be avoided to ensure a long lifespan.

Pay attention to this when the rechargeable battery is attached to the model or removed from the model.
• Ensure that the rechargeable battery does not overheat during usage, recharging, discharging, transport
or storage. Do not place the rechargeable battery adjacent to sources of heat (e.g. cruise control, en-
