Battery Voltage

CAUTION: D0 NOT use a 4-cell 4.8-volt battery to power
the PowerSafe.
Four-cell 4.8-volt batteries do not provide enough voltage headroom (additional
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
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. LiPos offer
greater capacity for their size and weight, and are easier to manage when
charging. Before using LiPo batteries, please check the voltage specifications
(SPMVR6007), 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 to prevent over discharge.

Installation

The PowerSafe requires
a minimum of three
remote receivers to
operate and one receiver
must be plugged into the
A receiver port. Three
remote receivers are
included and in most
cases it is recommended
that three or four receivers
be used. Each receiver
functions independently
and additional receivers
(up to four) offer a more
secure RF link in difficult
environments. The added
security of redundancy
should a failure occur
outweighs the slight
additional weight
and cost penalties.
