The Bixpy Extension Cord allows you to place your Outboard Power Pack further from your motor. If you would like to store your battery in the front hatch of your kayak or Standup Paddle Board or simply want the battery further from your motor, this is what you'll need. Like any other extension cord, you can plug multiple cords together to achieve a desired length.
It is important to remember that extension cords do reduce the efficiency of the system, specially at higher speeds. So buy the shortest cable you need for your purpose. There is roughly a 1% to 4% power loss with a 4.5 ft extension cord and a 2% to 8% power loss with the 9 ft cable.
