Do not use other type of battery except Lithium Polymer 3 cell battery. Maximum battery current should not exceed 8
A. When battery voltage is less than 12.6 V the charger charges the battery with current of <2 A. It is recommended to
connect battery to the system through the switch with current rating not less than 10 A.
When the battery source is used, GPU is not producing exactly 12 volt power output, please see Figure 10 for details.
The battery voltage and output voltage difference is approximately 0.4V and GPU cannot provide 12 V voltage if battery
voltage is less than 12.4 V and starts to operate with 100 % duty cycle.

External Power Supply
External power supply can be used as a power source when the engine is no operating. This is especially useful for
laboratory environment testing, during set-ups, during pre-flight checks on field as well as for charging the onboard
battery. The input voltage range should be in range of 13-50 Volts.

Connector Description
GPU enclosure has two electrical connectors - J1 and J2, as seen on Figure 11. Pinout of J1 connector is shown in Figure
12 and is the same for both, brushed and brushless GPU configurations.
Please note, pinout of J2 connector is different for brushless and brushed GPU configurations. Figure 13 shows pinout
configuration for brushless GPU option and Figure 14 shows pinout configuration for brushed GPU option.
