Garmin LiveScope sonar has changed the way anglers fish by providing live, forward-facing sonar views that reveal fish movement and underwater structures in real time with impressive detail.
LiveScope units generally draw between 20 and 30 watts, which means they need a power source that can deliver steady output for long periods. A common question many anglers ask is whether a deep cycle battery can be used for LiveScope. The short answer is yes. In fact, deep cycle batteries—especially lithium deep cycle batteries—are among the most suitable options.
This guide explains how deep cycle batteries support LiveScope, compares available battery types, and helps you select the right battery setup to ensure reliable performance on every fishing trip.
What Is a Deep Cycle Battery and Why It Works Well with LiveScope
A deep cycle battery is designed to provide consistent, long-duration power, unlike starting batteries that are built to deliver short bursts of high current to start an engine.
These batteries are engineered to handle repeated deep discharges—often up to 80–100% of their capacity—followed by recharging. This makes them ideal for electronics such as LiveScope, trolling motors, GPS units, and marine navigation systems.
Popular marine formats like the Group 24 size are commonly used in LiveScope installations. Among all deep cycle options, lithium iron phosphate (LiFePO4) batteries stand out for their long service life, reduced weight, and stable voltage delivery—key benefits for sensitive, high-performance sonar systems.

Can a Deep Cycle Battery Run Garmin LiveScope
Deep cycle batteries are well suited for powering Garmin LiveScope systems because they supply steady, uninterrupted energy required for real-time sonar processing.
Maintaining stable voltage is critical. It helps prevent issues such as screen flickering, signal dropouts, or inconsistent sonar readings during operation.
A high-quality lithium deep cycle trolling battery can easily support long fishing sessions, whether you’re targeting walleye in deeper water or scanning unfamiliar structure. This level of reliability allows you to focus on fishing rather than monitoring battery levels.
Battery Types Compared for LiveScope Use
Selecting the correct battery chemistry plays a major role in LiveScope performance. The two most common choices are traditional lead-acid batteries and modern LiFePO4 lithium batteries. The comparison below highlights their differences:
| Feature | Lead-Acid Batteries | LiFePO4 Batteries |
|---|---|---|
| Weight | Heavy (approx. 14–23 kg for 50Ah) | Lightweight (approx. 4.5–7 kg for 50Ah) |
| Service Life | 300–500 charge cycles | 2,000–5,000 cycles (at 80–100% depth of discharge) |
| Charging Time | Slow (6–12 hours) | Fast (2–4 hours) |
| Maintenance | Regular electrolyte checks required | No maintenance required |
| Voltage Consistency | Voltage drops as battery drains | Voltage remains stable |
| Typical Cost | Lower upfront (CAD $140–$270 for 50Ah) | Higher upfront (CAD $420–$800 for 50Ah) |
Compared with lead-acid options, LiFePO4 batteries are widely regarded as the best lithium battery for LiveScope. Their efficiency, extended runtime, and voltage stability make them far better suited for advanced marine electronics. While lead-acid batteries may appear more affordable initially, their weight, maintenance needs, and shorter lifespan often make them less practical over time.
Why a LiFePO4 Deep Cycle Battery Is a Smart Choice for LiveScope
LiFePO4 marine trolling batteries are engineered to meet the power demands of LiveScope systems. Key benefits include:
- Consistent Voltage Output: Helps maintain sharp sonar images and smooth real-time performance.
- Reduced Weight: Typically 50–70% lighter than comparable lead-acid batteries, ideal for kayaks and smaller boats.
- Extended Runtime: Higher usable capacity means more hours on the water without recharging.
- Quick Recharging: Shorter charge times reduce downtime between trips.
- Long-Term Durability: With 2,000–5,000 cycles at high depth of discharge, LiFePO4 batteries can last up to ten times longer than lead-acid alternatives.
12V vs. 16V Batteries for LiveScope Systems
Most LiveScope units, including models such as the LVS34, operate within a 10–32V input range. This means both 12V and 16V batteries can be used, depending on your setup. Always confirm compatibility in your device manual.
- 12V Batteries: Widely available and budget-friendly. A 12V 30Ah lithium battery can typically power LiveScope for around 8–12 hours.
- 16V Batteries: Higher voltage can improve sonar sharpness and refresh speed. A 16V 30Ah battery often delivers 10–12+ hours with enhanced image clarity, making it popular with tournament anglers.
If maximum sonar performance is your priority, a 16V battery provides a noticeable advantage, particularly during long or high-intensity fishing sessions.
Long-Term Cost Comparison: Lithium vs. Lead-Acid
Although LiFePO4 batteries cost more upfront, they often deliver better value over time. For example, a 50Ah LiFePO4 battery priced around CAD $550 can last 2,000–5,000 cycles, while a lead-acid battery costing about CAD $200 may only last 300–500 cycles. Over a five-year period, replacing multiple lead-acid batteries can exceed the cost of a single lithium battery, resulting in potential savings of several hundred dollars. Faster charging and minimal maintenance further reduce long-term expenses.
Safety Features of Lithium Deep Cycle Batteries
LiFePO4 batteries are well suited for marine environments and include important safety features such as:
- Built-in Battery Management System (BMS): Protects against overcharging, overcurrent, overheating, and ensures cell balancing.
- Thermal Stability: LiFePO4 chemistry is highly resistant to thermal runaway.
- Durable Construction: Many models offer IP65-rated protection against moisture and include low-temperature safeguards for cold-weather use, including ice fishing.
These features make LiFePO4 batteries a dependable and safe power source on the water.
How to Select the Right Battery for LiveScope
When choosing a battery for LiveScope, consider the following factors:
- Capacity (Ah): Estimate using Ah = (LiveScope watts ÷ voltage) × operating hours. For a 30W load over 8 hours, a 12V 20–30Ah battery is sufficient, while 50Ah is better for longer trips or multiple devices. You can also use the Vatrer online calculator tool.
- Physical Size and Weight: Compact lithium batteries are ideal for limited spaces.
