POWER BOX Evolution 40/16

You should check before every flight - by “stirring the sticks” - that the voltage of
both batteries remains stable. If the batteries in your model are too “weedy” for the
application, i.e. of inadequate capacity, this check will immediately show up the
shortcoming. In general terms, small batteries of high capacity are not suitable for
use as receiver power supplies because they have very high internal resistance;
this means that their current delivery capacity is often inadequate for powerful, high-
speed digital servos.
Please believe what the voltage display tells you!
For even better monitoring of the power sources, the battery backer also features a
minimum value memory (low voltage memory) for both packs. This memory
records all voltage collapses - separately for each battery - during the flight.
This is a very important feature, as it provides you with important information
regarding battery performance. You can now check the state and capability of your
batteries in a long-term test (over the full duration of the flight) as well as in a brief
pre-flight test.
After each flight you can call up the minimum voltage memory by “pressing” both
sensor buttons I and II simultaneously before switching the system off.
The memory is reset when you switch off the power supply system; the recording
process begins anew when you switch on again.
The voltage display is not linear, but matched to the discharge curve of today’s
Nickel-Cadmium (NC), Nickel-Metal-Hydride (NiMH) and Lithium-Polymer (LiPo)
cells. It is not possible to make general predictions regarding useful battery
operating times, because this varies according to the battery capacity, the number
of servos, the type of servos, and the frequency of control commands.
The PowerBox 40/16 Evolution is switchable to suit different battery types, i.e. you
can switch the unit from NC to LiPo batteries yourself.
The default setting is for LiPo batteries. If you wish to switch the unit to suit NC
batteries, first disconnect the two power supply batteries from the PowerBox.
