This power distribution board is designed for large UAVs, typically those used for industrial applications such as crop spraying or heavy lifting. It supports quadcopter and hexacopter installations and is rated at a massive 480amps. The board features two sets of power input wires which are connected in series - connecting two 6S LiPO packs will a deliver 12S output to the ESC / Motors power connections. If you require a 6S power supply, connect two 3S batteries in series or just one 6S battery to the red/black wires on the left. There are also auxiliary power outputs on the PDB - 2x 12S connections and 2x 6S connections. Note these are not regulated power supplies; their output voltage will depend on the voltage of the batteries / battery connected. The board makes use of XT90 female connectors for the ESC power outputs and XT60 female connectors for the auxiliary power outputs so you will require male XT90 / XT60 connectors. Finally, the board features ESC signal inputs labeled M1 to M6. The connections are outputted together respectively at the signal hub, ready for you to connect with your flight controller. For the main power input wires, we recommend that you use the Amass AS150 7mm anti spark connectors. IMPORTANT: Do not connect a battery to the middle red and black wires - they are connected together and will short your power supply.
