What battery for my fish finder?

Most fish finders run on 12V. A dedicated deep-cycle battery (separate from your engine battery) is recommended to avoid draining your start battery. Size depends on screen size and hours of use.

Do I need separate batteries for electronics?

Highly recommended — running electronics from your engine battery risks not being able to start your motor. A separate 12V deep-cycle dedicated to electronics is best practice.

What gauge wiring for marine electronics?

Follow manufacturer specifications — typically 16-12 gauge depending on current draw and cable run length. Use marine-grade tinned copper wiring for corrosion resistance in saltwater environments.

How long will a battery run my sounder?

A 12V 7Ah battery runs a small sounder for 8-12 hours. Larger screens need more — 12-20Ah recommended for full-day fishing. Lithium batteries offer better performance-to-weight than lead-acid.
