Can I Use a Deep Cycle Battery for Livescope?

Livescope has changed the game for anglers by providing real-time sonar imaging with stunning clarity and accuracy. Advanced fish finders like Garmin Livescope greatly enhances the fishing experience. But powering this advanced technology requires a reliable battery setup. One of the most common questions is: Can you use a deep cycle battery for Livescope?

The short answer is yes—a deep cycle battery is not only compatible but ideal for Livescope. In this article, we’ll explore what is a deep cycle battery, the different deep cycle battery types, and how to choose the best battery for Livescope.

What is a Deep Cycle Battery?

A deep cycle battery is designed to deliver a steady amount of current over a long period and withstand deep discharges. Unlike starter batteries, which give short bursts of power to start engines, deep cycle batteries are made to be drained down to 80%-100% of their capacity and recharged repeatedly.

These deep cycle marine batteries are ideal for powering electronics like:

• Fish finders (including Livescope)
• Trolling motors
• Lighting and accessories
• Navigation systems

Can a Deep Cycle Battery Power a Garmin Livescope?

Yes! A dependable and reliable power source is essential to get the full performance from your Garmin Livescope, and a deep cycle battery is well-suited for the task. With sufficient capacity and stable voltage, a quality deep cycle battery can keep your Livescope operating smoothly throughout long days on the water, allowing you to stay focused on fishing.

What Kind of Battery is Best for a Livescope?

Deep cycle batteries come in various types, but the two most common for fish finders are lead-acid and lithium iron phosphate (LiFePO4).

1. Lead-Acid Batteries

Includes flooded, AGM, and gel batteries. These batteries work, but they are not the most efficient or reliable option, especially for high-performance electronics like Livescope.

Pros:

• Lower upfront cost
• Widely available

Cons:

• Heavier and bulkier
• Slower charging
• Voltage drops significantly as the battery discharges
• Shorter lifespan (typically 300–500 cycles)
• Need regular maintenance

2. Lithium (LiFePO4) Batteries

While lead-acid batteries can power your Livescope, LiFePO4 lithium deep cycle batteries are clearly the superior choice in terms of efficiency, reliability, and performance.

Pros:

• Lightweight (up to 70% lighter than lead-acid)
• Consistent voltage throughout discharge
• 3000–5000+ cycles for long life (Redodo LiFePO4 can reach 4,000-15,000 cycles)
• 100% usable capacity
• Maintenance-free and fast charging

Cons:

• Higher upfront cost (but better long-term value)

Why Use Lithium Deep Cycle Battery for Livescope?

Modern fish finders and Livescope draw a significant amount of power because of their advanced sonar functions and real-time imaging. That’s why it’s important to use a separated battery capable of meeting these energy demands while ensuring continuous operation. In this case, a lithium deep cycle battery stands out as an excellent choice.

• Stable Voltage for Clear Imaging: Lithium batteries maintain a consistent voltage throughout the discharge cycle, which ensures your Livescope runs smoothly without screen flickering or sonar dropouts.
• Lightweight for Easy Transport: Perfect for kayaks or mobile anglers, lithium batteries weigh far less than lead-acid options, reducing your load significantly.
• Longer Runtime with Full Capacity Use: With higher energy density, a lithium battery has a longer runtime than lead-acid, ideal for full-day fishing trips.
• Fast Charging Between Trips: Need a quick turnaround between fishing days? Lithium batteries recharge much faster, helping you get back on the water sooner.
• Longer Lifespan and Better Value: Although the upfront cost is higher, lithium batteries last 3 times longer than traditional options, saving you money over time.

12V vs. 16V Battery: Which is Better for Fish Finder Livescope?

With more and more fish finder battery options becoming available, 16V batteries are increasingly being considered alongside traditional 12V options. If you're looking for better performance and efficiency, the 16V option comes out on top. Here’s why:

• 12V batteries: The traditional go-to and remain widely used because they’re compatible with most fish finders and marine electronics. They’re easy to source, generally more affordable, and work well for casual anglers or standard setups. A high-quality Redodo 12V lithium battery can still provide reliable, all-day performance for your Livescope.
• 16V batteries: These higher-voltage batteries are becoming a smarter choice. The higher voltage allows your Livescope to run more efficiently, with faster screen refresh rates, improved clarity, and reduced current draw. This can be especially beneficial during long fishing sessions or tournament use when consistent output power delivery matters most.

Redodo’s 16V 30Ah lithium fish finder battery is specifically designed for fish finders like Garmin Livescope, offering extended run time, better energy conversion, and stable voltage output. If your device supports 16V input, upgrading to this higher-voltage battery can enhance your overall fishing experience by delivering more responsive sonar imaging and longer usage on the water.

How to Choose the Best Battery for Livescope Fish Finder?

When selecting the best battery for Garmin Livescope fish finder, consider the following key factors to ensure optimal performance and reliability:

Size and Weight

A compact, lightweight LiFePO4 battery is easier to mount and transport, especially important for kayaks or small fishing boats.

Battery Capacity (Ah)

Higher capacity means longer run time. A 20Ah lithium battery can handle a full day on the water, but if you're running multiple electronics or want longer runtime, a 30Ah to 50Ah battery may be a better fit to power your Livescope.

Equipment Compatibility

Ensure the battery voltage (12V or 16V) is compatible with your fish finder and other onboard electronics.

Charging Speed

Fast-charging batteries reduce downtime between uses, helping you get back on the water quickly.

Low-Temperature Performance

For ice-fishing anglers, pick a ice fishing battery with low-temp protection that can safely charge and operate in low temperatures without performance loss.

Additional Functions

Features like Bluetooth connectivity let you monitor battery status, voltage, and health in real time from your smartphone, adding convenience and peace of mind.
