The main function of the distribution board is to connect the batteries and distribute the battery voltage to different power consumption parts. It can divide the input voltage into multiple channels and output multiple channels of the same voltage to achieve voltage distribution In drone applications such as model aircraft, the distribution board is particularly important because it can divide the voltage without changing it, allowing different electronic devices to work at the same time Comes with dual battery pads Comes with 12 , compact and portable Easy to install, you can install it successfully without complicated steps Name: PDB Board Wheelbase: Main Splint Applicable Type: Drone Tools And Supplies: Collections 4wd : Gathering Upgrade Parts/Accessories:400A PDB RC Parts & Accs:PDB Color: Black Material: PCB Package Contents: 1 * PDB Board 2 * Cables 1 set of Loose Tools Only the above package content, other products are not included.
