• Disconnect the boat battery from the model before connecting it to the charger. Never leave the battery
connected to a speed controller when it is charging. This may damage the charger, speed controller or
the battery! Always remove the battery from the model boat before recharging it.
• Placethechargerandrechargeablebatteryonanon-ammable,heat-resistantsurface(e.g.stonetiles).
Keepthechargerandbatteryawayfromammableobjects.Maintainasufcientdistancebetweenthe
charger and the battery. Never place the battery on top of the charger.
• 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.
• Ensurethatthereissufcientventilation,asthebatteryandchargermayheatupduringthecharging
process. Never cover the charger or the rechargeable battery!
• Never leave batteries unattended when they are charging. Inspect the charger at regular intervals to
ensurethatthebatteryisnotoverheatingorexpanding.Thisindicatesanimminentriskofareorexplo-
sion. If the battery overheats or starts to expand, disconnect it from the charger immediately and take it
toalocationwhereitwillnotcauseanyadditionaldamageifitexplodesorcatchesre(e.g.outdoors).
• Disconnect the battery from the charger when it is fully charged.
• Never damage the casing of a rechargeable battery. Never charge damaged, leaking or deformed bat-
teries.Thismaycauseareorexplosion!Discontinueuseimmediatelyanddisposeofthebatteryinan
environmentally friendly manner.
• Rechargeable batteries should be charged regularly (approx. once every 2-3 months) to prevent them
from overdischarging. This may result in permanent damage and render the batteries useless.
LiPo/Li-Ion batteries usually retain their charge for several months. However, if the batteries overdis-
charge, this will result in permanent damage and render them useless.
b) Additional information about lithium rechargeable batteries
Modern lithium rechargeable batteries have a signicantly higher capacity than NiMH and NiCd bat-
teries and are more lightweight. This makes lithium batteries (especially lithium polymer batteries)
particularly suitable for use in model making.
However, LiPo/Li-Ion batteries require particular care to ensure safe charging/discharging, opera-
tion and handling.
The following section provides an overview of the potential hazards associated with LiPo/Li-Ion
batteries and explains how these hazards can be avoided to ensure a long lifespan.

drop or insert any objects into lithium batteries. Do not apply mechanical loads or pull on the battery’s
connectioncables.Thismaycauseareorexplosion!
Always observe these instructions when inserting or removing a battery from your model.
• 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reorexplosion!The
temperature of the battery must not exceed 60 °C (or the maximum temperature stated on the battery).
