4. IGNITION BATTERY
Any type of ignition battery can be used: LiPo, LiIon and LiFe up to 3S, 8S NiCd or
NiMh. When connecting the battery, it is essential to maintain correct polarity!
Reversed polarity will destroy the electronics in the SparkSwitch RS.
The regulated version of the SparkSwitch RS incorporates an integral regulator
which basically limits the voltage to 6.0V. This makes the SparkSwitch RS suitable
for all ignition units whose label states 4.8V and 6.0V.
The unregulated version passes the full, unregulated input voltage (max. 13V) th-
rough, with low losses.
This means: if you connect a 2S LiPo, the ignition unit is fed a voltage of up to 8.4V;
with a 3S LiPo it is up to 12.6V.
The ignition battery can be left permanently connected to the SparkSwitch RS.
The current drain when switched off (1 μA) is so low that the battery will not be
discharged even over a period of months.
5. RPM DIVIDER / MULTIPLIER
Depending on the type of RPM sensor you are using, it may be necessary to set up
a divider or multiplier to obtain the correct rotational speed. PowerBox (Telemetry
menu) and Jeti (JetiBox) users can set this directly from the transmitter; other sys-
tems require these settings to be changed using Terminal and the USB Interface.
