Ni-cd Battery Charging Precautions
WARNING
Always charge the nicd
battery before each flight.
If the battery goes dead during
flight, the plane may crash.
Charge the digital proportional R/C nicd
battery with the special charger, or digi-
tal proportional R/C quick charger, sold
separately.
Overcharging may cause burns,
fire, injury, blindness, etc. due to
overheating, breakage, electro-
lyte leakage, etc.

batteries.
During quick charging, the bat-
tery holder contacts may over-
heat and damage the equip-
ment, or prevent charging.
Do not short the nicd battery connec-
tor terminals.
Shorting the terminals may cause sparking and
overheating and result in burns or fire.
Do not drop or apply strong
shock to nicd battery.
The battery may be shorted and cause
overheating or breakage and electro-
lyte leakage and result in burns or
damage by chemical mater.
