The 16-Volt Battery Debate: The Real Solution to Better Electronics Performance

It's one of the most common questions we see on forums and get in the shop: "Do I really need a 16-volt battery for my graphs and live sonar?" The idea is that more voltage will produce a cleaner image, and many anglers are turning to this solution to solve performance issues.

At BassFishinElectronics.com, we’ve run extensive tests on this theory, and what we've found might surprise you. A 16-volt battery is often a band-aid for a more fundamental problem in your boat's electrical system.

The Problem Isn't Your Battery, It's Your Wiring

The real culprit behind inconsistent performance and image quality is typically voltage drop caused by poor-quality or undersized wiring. When your graphs and live sonar aren't getting the dedicated, clean power they need, their performance suffers. A 16-volt battery can compensate for this voltage drop, but it doesn’t fix the underlying issue.

Our tests have consistently shown that a good-quality 12-volt lithium battery, when paired with a proper heavy-gauge wiring harness and solid connections, will deliver the best possible returns to your graphs. This setup provides stable, dedicated power that allows your electronics to operate at peak efficiency and display the absolute best image they can achieve.

Don’t just put a band-aid on a poor electrical system. Invest in a proper foundation with quality wiring and a reliable 12-volt lithium battery. You'll get better performance and a long day on the water with consistent voltage.
