Instruction manual JetCat-PRO engines, 1.7 - V12.01V
Power connector (B)
Power supply:
Only use 3s LiPo battery with at least 3000mAh capacity should be used.
The battery plugs directly into the engine or is connected via the JetCat Pro-interface.
NEVER use a switch between the battery and engine!!!.
If you plan to store the model for more than a few weeks, the battery should be disconnected.
Alternatively, a 12V DC power supply with at least 35A rating or a 12V lead battery can be used.
Verify for correct polarity (+/-)! There is no internal reverse voltage protection!
Reverse voltage will damage internal electronics.
To power up / switch on the engine system, an appropriate voltage needs to be supplied to the pins 9/1 of
the data connector (see connector pinout). This control voltage can be taken from the main supply battery.
If the PRO-Interface is used this control voltage is derived from one of the RC-control inputs (Thr/Aux). In this
case, the system powers on automatically when the receiver is switched on.
Attention!
Fire!
A LiPo/LiFePo battery can explode if incorrect charge parameters are used. You should
therefore always refer to the manufacturer's charger instructions.
NEVER
charge the batteries
unattended.
Do not exceed the batteries maximum allowed charging current.
READ AND OBEY
WARNINGS ON BATTERY BEFORE CHARGING!
On newer PRO engines, the supply voltage can range from 10-35V max. On these newer systems the battery type and
cell count is adjustable in a large range. On these engines the output voltage of the integrated DC/DC converter will
automatically adjust in correspondence to the selected battery! (only GL/GH versions).
On older GL/GH engines the battery must be a 3s Lipo type, as the output voltage of the DC/DC converter is fixed and
matched to these battery voltages!
Always ensure the batteries are at their optimal charge state before use. The battery is heavily
loaded because of the kerosene start. Please also note that at very low ambient temperatures,
LiPo/LiFePo batteries have lower capacities.
IMPORTANT: DO NOT INSERT A SWITCH BETWEEN THE BATTERY AND ENGINE connector
.
