Battery Voltage
IMPORTANT: D0 NOT use a 4-cell 4.8-volt battery to power the
PowerSafe receiver.
Four-cell 4.8-volt batteries do not provide enough voltage headroom (additional
margin needed) necessary to power the system when heavily loaded. Under load
the system voltage can drop below the voltage system's minimum operating
voltage threshold (3.5 volts) and cause loss of control.
The PowerSafe receiver is capable of handling voltages from 6.0 to 10.0 volts.
The voltage limitations are generally the servos. Most servos are compatible with
5-cell 6-volt packs. Five-cell 6-volt NiMH packs have become the standard for
many giant-scale applications.
Be aware that NiMH batteries have a tendency to false peak when being fast
charged. Be especially careful when using NiMH batteries that they are fully
charged and have not false peaked.
Many pilots are using 2-cell LiPo batteries to power their aircraft. LiPo batteries
offer greater capacity for their size and weight, and are easier to manage when
charging. Before using LiPo batteries, please check the voltage specifications
of your servos. Use of a voltage regulator, such as the Spektrum VR6007 (SPM-
VR6007), might be necessary.
When a battery is connected to the PowerSafe, a low current drain of less than
1mA occurs even when the switch is turned off. If the system is going to be
stored for any length of time, it's important that the battery(s) be disconnected
from the PowerSafe receiver to prevent over discharge.

Installation

The PowerSafe receiver requires a minimum of one remote receiver to operate.
Two or three remote receivers are included and, in most cases, it is recommen-
ded that two or three receivers be used. Each receiver functions independently
and additional receivers (up to three) offer a more secure RF link in difficult envi-
ronments. The added security of redundancy should a failure occur will outweigh
the slight additional penalties of cost and weight.
