Product Description

16V 52Ah Sonar Fish Finder Battery + Charger

Ionic 16 volt 52ah lithium sonar battery and charger image overlay, with the background of two bass fishermen fishing in a bass boat on a lake, with woods at the edge of it and the sky and clouds above them. Tired of poor performance? Cluttered images on your screens?

12V batteries suit basic fishing needs, but for advanced sonar systems, they’re not enough. Power your sonar electronics (the big brands; see customer feedback below) with our forward-facing 16V lithium fish finder battery, and you’ll see a BIG difference.

Our 16V 52Ah lithium battery is able to maintain crystal-clear images and minimize interference, because it’s engineered specifically for sonar applications.

It’s compatible with all major brands and offers dependable, long-lasting energy for clearer exploration. Tailor-made for enthusiasts who demand precision and durability, this sonar battery isn’t merely an accessory—it’s an essential upgrade, ensuring your sonar screens deliver unmatched clarity and performance.

This 16V lithium fish finder battery helps make the display on sonar and other marine electronics clearer. It’s not just about the higher voltage; lithium fish finder batteries (LiFePO4 marine batteries, not lithium-ion batteries) play a crucial role in powering and improving the functionality of the device in use. Compared to traditional lead acid batteries/sealed lead acid batteries, the lithium battery offers superior portability and performance, making it an ideal choice for anglers. Here’s how our sonar battery accomplishes that:

Stable Battery & Charger For Your Fish Finder 

A 16V sonar battery provides a more stable and consistent power supply to electronics vs a traditional lead acid battery, which is crucial for maintaining the optimal performance of sensitive equipment like forward-facing sonar and marine electronics. Marine lithium batteries offer significant benefits over traditional lead acid batteries, like lighter weight, longer lifespan, and more efficient usage. Additionally, marine lithium batteries provide a stable power supply, preventing the fluctuations and drops in electronic performance often experienced with traditional lead acid batteries, which can affect the clarity and detail of the information displayed.

Over time and with extended use, especially under high demand, traditional 12V battery systems can experience voltage drops, which might affect the performance and clarity of electronic displays. A 16V battery system can sustain higher voltage levels for longer periods, ensuring that electronics operate within their ideal power range.

Enhanced Signal Strength

Some marine electronics can benefit from the higher operating voltage by producing stronger signals. For sonar units, a stronger signal might translate into better penetration and clearer returns from underwater structures, which improves the overall clarity of the sonar image.

Dedicated Power Source

Using a separate battery, particularly a dedicated 16V sonar battery, is crucial for fish finders, especially in boats without an electrical system. This isolation means they’re less likely to be affected by power draws from other equipment on the boat. This can prevent interference and noise that might degrade the quality of the product, electronic display, and signal clarity.

Enjoy a peaceful boating experience with our lithium battery’s silent operation. Designed to function independently, it works seamlessly without contributing any additional noise, ensuring a more serene atmosphere on the water.

Designed for Optimal Positioning

We understand that the effectiveness of your sonar technology hinges on the strategic placement and use of your power source. That’s why our 16V fish finder battery features an innovative built-in mount, enabling seamless integration into the front compartments of your boat. This close proximity to your sonar screen not only boosts signal quality but also optimizes your setup for efficiency and aesthetics. With LithiumHub, your equipment is perfectly aligned with your ambitions.

Your 16V Lithium Sonar Battery: The Complete Power Package

Every Ionic 16V battery comes with its dedicated 16V charger, providing a holistic power solution right from the start. This charger is specifically designed to match the battery’s high standards, promising quick, efficient charging without compromising longevity. Together, they ensure your sonar system is powered up and ready when you are, maximizing your time on the water.

Frequently Asked Questions

Will this work with my forward-facing sonar (Garmin Livescope, Lowrance ActiveTarget, Humminbird MEGA Live, etc.)

Yes. The 16V 52Ah battery is engineered specifically for forward-facing sonar systems and is compatible with all major brands of FFS and marine electronics. The higher voltage produces stronger signals and cleaner images on your sonar screen compared to a standard 12V battery.

Do I need a special charger, or can I use my existing 12V charger?

You need a dedicated 16V charger — a 12V charger won’t fully charge this battery. Every Ionic 16V battery ships with a matched 16V 6A charger included in the box, so you have everything you need from day one. The included charger carries a 1-year warranty.

Is the higher 16V voltage safe for my sonar electronics?

Yes. Most modern forward-facing sonar units are designed to accept the higher voltage and actually perform better with it — the 16V supply maintains a more stable voltage under load than a 12V battery, preventing the voltage drops that degrade sonar image clarity over a long day of fishing. Compatibility extends across all major sonar brands.

How do I mount this battery in my boat?

The battery has a built-in mounting bracket for installation in the front compartment near the sonar screen or black box. Its slim form factor (13.9″ × 6.4″ × 4.1″) also lets you mount it inside a rod locker. Quick-connect positive/negative posts with a quick-screw wire securing system make installation straightforward — no wire splicing needed.

Is this battery safe to use on the water?

Yes. The case carries an IP67 rating — fully protected against dust and able to withstand temporary submersion in water up to 1 meter, well beyond splash, rain, or spray on a boat deck. The ruggedized ABS + PC construction handles the vibration and impact of rough water.

Great value

Overall I’m pleased with the performance. I run 2 Lowrance Pros (12” & 16”) and one Lowrance Live 12”. After 8 hours of fishing, battery level was 23%. I kinda wish that the battery was at least 75 Ah, as I sometimes fish longer days. Other than that, I can find no fault with this battery. Price was surprisingly reasonable.

16V

Been out a couple of times enough to drain battery down to 60% after 4 hours of fishing. But I never worry about running down. Knowing the percentage of your battery is a huge. But my question is at what percentage would you charge it back up.

16v battery and charger

I haven’t had a chance to install them yet but I’m running four other Ionic batteries in the boat so I’m sure it work just as good. I’ve been using them for four years now without any issues

FFS Battery

This is the second Ionic Battery I have in my boat. Both batteries are 50 Amp-he and both are great. They have a premium feel in terms of the casing material and overall appearance. Easy to hook up and mount. Both work flawlessly. The trolling motor battery is charged through my Power Pole charger that charges on the fly through the motor or at home. The FFS battery is an isolated circuit and charges on the Ionic charger at home. Both batteries last so much longer than lead acid and weigh so much less it has been an astounding upgrade. The FFS battery running AT 2 with a 12” monitor can go several days before needing a charge. This has been great when going out on a 2-3 fishing trip. The Ionic app is a must have as it quickly loads and not only provides charge status but several other parameters that are useful in assessing your battery health and performance. All in all, I expect these will last for years and years. Highly recommend getting premium batteries over bargain basement Lithium Iron Phosphate.
