Battery Requirements

IMPORTANT: Do not use a 4-cell 4.8-volt battery to power the
AR7100/AR7100R.
Because of the built-in regulator the AR7100/AR7100R has a minimum
recommended operational battery voltage of 5.5 volts and is designed
to use 6-volt 5-cell NiMH, 7.2-volts 6-cell NiMH or 7.4-volt 2-cell
LiPo batteries. (Higher voltage should be used only if the servos are
compatible.) While the AR7100 will continue to operate down to 3.5
volts, the AR7100/ AR7100R features a built-in 5.2-volt regulator for the
Rudder, Aux 2, Gear 2, Throttle 2 channels output. A 4-cell 4.8-volt battery
will not provide sufficient headroom (voltage margin) to maintain a 5.2
regulated voltage. Regulated outputs are provided to allow the gyro, gyro
gain and throttle to be operated at the necessary lower voltage while the
cyclic servos (aileron, elevator and pitch) are powered directly by the pack
voltage (typically 5-cell 6-volt NiMH or if high voltage compatible servos
are used 2-cell 7.4-volt LiPo batteries).
