How can i fuel the rov to test the engines if i still do not have the batteries? Please help me.
I used a single 12VDC battery connected to both of the leads
On the edge of the controller board by the ESCs there’s a set of contacts (J11) to allow you to hook up a battery for testing purposes. Be careful with this though- that input has no reverse-polarity protection, so if you hook a battery up to it backwards you will probably destroy the board.
