3.4. IGNITION BATTERY
All types of ignition battery can be used: LiPo, Li-Ion and LiFe up to 3S, NiCd or
NiMH up to 5S. Take care to maintain correct polarity when connecting the battery,
as reversed polarity will ruin the electronics in the SparkSwitch PRO.
The unit’s integral regulator basically limits the voltage to 5.9 V, which means that
the SparkSwitch PRO is suitable for all battery types such as 4.8 V, 6.0 V. For all
other types of ignition unit please disable the integral regulator using PowerBox
Terminal.
Note: if you wish to use batteries with a voltage higher than 8.4 V, it is essential to
disable the 5.9 V voltage regulation circuit, otherwise the integral voltage regulator
will overheat under load.
The ignition battery can be left connected permanently to the SparkSwitch. The
current drain when switched off is so low (60 µA) that it will not discharge the
battery even over a period of months
