b) Transmitter
• Use batteries or rechargeable batteries for the transmitter.
• Always replace the entire set of batteries or rechargeable batteries in the transmitter.
• When using rechargeable batteries in the transmitter, the operating duration will reduce due to the low voltage (rated
voltage of the battery = 1.5 V, rechargeable battery = 1.2 V).
If you want to use rechargeable batteries anyway, we recommend use of NiMH rechargeable batteries with low
self-discharge.
• If you do not use it for any extended period of time (e.g. during storage), remove the batteries/rechargeable batteries
inserted in the transmitter to prevent damage from leaking batteries/rechargeable batteries.
c) Vehicle
• Use only two Li-Ion rechargeable batteries of type "17500" (rated voltage 3.7 V each) for the vehicle. Never use any
other rechargeable batteries or batteries in the vehicle.
• If you do not use it for any extended period of time (e.g. during storage), remove the rechargeable batteries inserted
in the vehicle to prevent damage from leaking rechargeable batteries.
• Never use rechargeable batteries with different charge states in the vehicle. Operation of the vehicle may otherwise
cause deep discharge of a rechargeable battery, which will cause permanent damage to it.
• Always use two Li-Ion rechargeable batteries of the same build for the vehicle (same manufacturer, same type,
same capacity).
• Charge the two enclosed Li-Ion rechargeable batteries only using the enclosed charger. Never use any other charg-
er; this may cause fire or explosion of the Li-Ion rechargeable batteries.
