• Place the charger and battery on a heat-resistant, non-combustible surface.
• Thechargerandbatterywillheatupduringthechargingprocess.Therefore,keepasufcientdistance
between the charger and the rechargeable battery, and never place a rechargeable battery on the

• Never leave batteries unattended when they are charging.
• Rechargeablebatteriesshouldbechargedregularly(approx.onceevery2–3months)topreventthem
from overdischarging. This may result in permanent damage and render the batteries useless.

LiPo batteries usually retain their charge for several months. However, if the batteries overdischarge, this
will result in permanent damage and render them useless.

capacity. Pay particular attention to the information of the rechargeable battery or charger manufacturer.
• Never use an excessive charging current. Observe the manufacturer's specications for the ideal/
maximumchargingcurrent.
• Disconnect the battery from the charger when the battery is fully charged.
• The charger and the rechargeable battery must not get damp or wet. This may result in a fatal electric
shockorcauseareorexplosion!
Lithium rechargeable batteries (e.g. LiPo batteries) contain chemicals that are very sensitive to moisture.
• This vehicle is only suitable for two LiPo drive rechargeable batteries with 2 cells (rated voltage 7.4 V) or
two LiPo drive rechargeable batteries with 3 cells (rated voltage 11.1 V).

speed controller overheating. In addition, the vehicle's drive will be overloaded and thus damaged (e.g.
differential). This will void the warranty!
The two drive rechargeable batteries must be identical (same rechargeable battery type, same capacity,
same discharge rate, same manufacturer, same type). Never use different drive rechargeable batteries
together,becausethereisariskofre!

a full and a half-full LiPo drive rechargeable battery to the speed controller in order to prevent a deep
discharge that will permanently damage the rechargeable battery.
