Considerations for Connecting Batteries in Parallel

Connecting batteries in parallel will double your run time without doubling your voltage. This will allow you to spend more time on the water without damaging your Cannon product.

  • Two 12-volt deep cycle batteries are required. Batteries in the system must be the same manufacture, type, size, and age.
  • Make sure that the downrigger is disconnected.
  • Wire in parallel only as directed in wiring diagram, to provide 12-volt system with increased amp hour capacity.

How to Connect Batteries in Parallel

  1. Connect a connector cable to the positive (+) terminal of battery 1 and to the positive (+) terminal of battery 2.
  2. Connect a connector cable to the negative (-) terminal of battery 1 and to the negative (-) terminal of battery 2.
  3. Connect positive (+) red lead (from downrigger) to positive (+) terminal on battery 2.
  4. Connect negative (-) black lead (from downrigger) to negative (-) terminal of battery 1.
