value. Of course, it is perfectly feasible to use both processes in parallel, in which case
the temperature monitoring process provides an additional safety margin when charging
at high currents. In this case you should select the desired Delta Peak sensitivity, and
set a termination temperature of, say, 45ºC.
- When charging NiMH batteries the value for Delta Peak sensitivity must be set to 0DV.
- The value for final charge voltage is not relevant when charging NiCD and NiMH
packs, and should be set to the maximum value of 53 V. If you set a different tempera-
ture, the charge process will terminate as soon as the pack reaches the set value.
General information regarding charging and discharging batteries
As a basic rule please be sure to observe the battery manufacturer’s recommendations,
especially the information regarding maximum charge currents.
To ensure that the automatic Delta Peak circuit is able to work as efficiently as possible,
only properly balanced packs should be fast-charged. This means that new batteries, and
packs which have not been used for a long time, should be discharged at regular intervals
and re-balanced by slow-charging at a low rate, typically C/10.
An occasional complete discharge process also helps to avoid and/or eliminate the
MEMORY EFFECT.
It is possible to charge a transmitter battery which is installed in the RC system transmitter,
but the charger’s discharge functions are only available if you either by-pass the protective
diode in the transmitter’s charge circuit, or remove the battery from the transmitter and
connect it to the charger using a direct charge lead.
Conversion work on the transmitter should only be carried out by an expert, ideally by your
nearest robbe Service Centre.

Notes
-
When charging and discharging packs using high charge or discharge currents it may
be necessary to allow the battery to cool down. This varies according to battery type.
- The maximum charge and discharge currents vary according to the number of cells in
the pack; see „Specification“.
- Don’t end the charge or discharge process simply by disconnecting the battery pack;
always stop the process by pressing the START/STOP button.
Charging transmitter and receiver batteries at the RX / TX output
The RX / TX output does not feature any form of automatic termination, and is designed
for charging transmitter and receiver batteries.
The charge current is approximately 250 mA, and this value may fall off slightly towards the
end of the process when charging an 8-cell battery, depending on the pack’s voltage curve.
Short-circuits and long-term reversed polarity must be avoided.
Never connect a pack consisting of more than 8 cells to this output.
