Battery
With the new PCI-HV ignition we have set the greatest value on a really strong spark.
Of course, high- energy sparks are not possible without higher input power from the
battery, but we believe this is a fair price to pay. With modern battery technology, the
battery weight no longer matters, so why not go for the best possible starting, reli-
ability and performance?
The PCI-HV ignition contains a very efficient voltage converter, which is capable of us-
ing the higher voltage instead of converting it to heat, as in the case of the common
linear voltage regulators. With the PCI-HV ignition the rule is: the higher the voltage,
the lower the current. Therefor it is best to use a 2s LiPo directly, without an external
regulator, the flying time will be the longest.
Beside the 2s LiPo battery, there are quite a few other options. This can be a two cell
A123 or LiFePO4 battery.
Also a 5 or 6 cell Sanyo Enerloop 2000 NiMh can be used.
Be warned, that if you go for a 4 cell NiCd or NiMH type, this has to be one with a low
internal resistance. When the voltage drops below 4.8 V, the engine will start to misfire.
A 2s LiPo is first choice for best capacity to weight ratio.

Under normal conditions, you will not fly at full
throttle and certainly not at 8000 RPM all the time,
therefor a 1000 mAh 2s LiPo battery is enough for
two hours flying with safety. The idle current with
engine stopped is approximately 30 mA. The PCI
ignition does
no longer
automatically shut down
when one minute has elapsed without the propel-
ler being turned. This safety switching in the past
has caused more frustration than doing any good.
