EVolution
Dear customer,
We are delighted that you have decided to purchase the PowerBox Evolution from
our range.
We wish you every success with your new PowerBox Evolution, and hope you have
loads of fun with it.
1. PRODUCT DESCRIPTION
The PowerBox Evolution is a modern power supply system containing all the electronic components required to power modern receivers, servos and models. Every
single element, ICs, micro-controller and electronic circuit which is essential to a
reliable power supply is duplicated!
Features:
- Dual regulated output voltage
- Enlarged heat-sink area for even higher performance
- Signal amplication for a total of six channels
- Three voltage indicator LEDs
- Minimum value memory displays any voltage collapses which occur in-ight
- Support for four battery types: LiPo, LiIon, NiMH/NiCd, LiFe
- Suppression of any servo feedback currents which might occur
This range of functions makes the PowerBox Evolution the ideal battery backer
for large model aircraft with wingspans in the range 2.0 m to 2.6 m, as well as
helicopters and gliders.

3. FIRST STEPS, THE UNIT IN USE
a) Connections
- First plug in all the servos to the desired channels. The channel assignment is
left up to you; for example, input 4 corresponds to output 4.
- Connect the receiver to the PowerBox Evolution using the six patch-leads sup-
plied in the set. Power is fed to the receiver via these leads.
- Now connect the SensorSwitch to the appropriate socket on the unit, ensuring
that the ribbon cable faces up as shown. In models subject to severe vibration
we recommend that you secure the ribbon lead by at least one additional point
to avoid the connector working loose. If the connector were to fall out, it would
have no effect on the switched state of the backer, but would prevent you switching the system off.
- The optional ultra-bright external LEDs can now be connected to the unit. We
urge you to connect them and mount them in the fuselage side, as they enable
you to detect battery problems when the model is ying.
- The nal step is to connect the batteries to the backer’s integral MPX connec-
tors. We recommend the use of batteries or 1500 mAh or 2800 mAh capacity
from PowerBox-Systems. If you prefer to use other makes of battery, or wish to
make up your own packs, it is absolutely essential to maintain correct polarity.
- Check twice rather than make a mistake! Connecting a battery with reversed
polarity will instantly ruin the backer’s regulators. In order to minimise power
losses, the backer does not feature reverse polarity protection. The + (positive)
indicator can be seen on the case cover.

b) The procedure for switching on and off
Switching the unit on and off is very simple, and the process effectively prevents
accidentally changing the backer’s status. This is the procedure:
Locate the SET button on the SensorSwitch and hold it pressed in until the central LED glows red. Now press buttons I and II in turn; the backer is now switched
on. Repeat the procedure to switch off: hold the SET button pressed in, wait until
the central LED glows red, then conrm by pressing buttons I and II in turn.
Once switched on, the backer can only be turned off again using the switch unit.
Intermittent contacts or interruptions in the power supply cannot cause the backer to be switched off permanently.
c) Setting the battery type
The default battery type setting is Lithium Polymer. If you wish to use two-cell
LiPo/LiIon packs, you therefore need to make no changes at this point. For all
other battery types adopt this procedure:
- Switch both batteries on.
- Hold the SET button pressed in, and watch the central LED on the SensorSwitch.
- The LED will light up, and then go out again after a brief period.
- After a few seconds the LED emits one brief red ash. If you now release the
button, you have selected the battery type LiPo/LiIon.
- If you allow the LED to ash twice before releasing the button, you have selected ve-cell NiCd/NiMH as the battery type.
- If you hold the button pressed in until the LED has ashed three times, the vol-
tage indicator is prepared for LiFe (A123) packs.
