Lithium Battery for Fish Finder - Lowrance Garimin Humminbird

Is it a good idea to run fish finders on separate batteries?

Using separate batteries for fish finders is generally advisable to improve performance and reliability. This setup reduces interference from other electronics, ensures a consistent power supply, and can extend the lifespan of both the fish finder and the main battery system.

Can I Use a Lithium Battery for My Fish Finder?

Lithium Iron Phosphate (LiFePO4) batteries are the premier choice for fish finders due to their long-lasting power. They offer higher energy density compared to traditional options and come equipped with a Battery Management System (BMS) to protect against over-current, short circuits, and other potential damage. Safety is a significant advantage of these batteries.

Using lithium batteries is smart for marine applications. They suit fish finders and trolling motors perfectly. Their design minimizes risk, making them reliable.

In summary, LiFePO4 batteries offer power, longevity, and safety. They enhance your fishing experience while ensuring peace of mind. Choose them for your next adventure on the water.

What are the differences between 12V & 16V lithium fish finder batteries?

Fish finders typically require a power input range of 10-32V, making a 12V battery suitable for most. However, some high-performance models and accessories need higher voltage.The 12V battery may experience a significant voltage drop during later use, while a 16V battery can maintain a higher safe operating voltage.

A 16V battery boosts the clarity and brightness of your fish finder’s screen. This enhancement allows you to see critical details in real time. The increased voltage improves the transducer’s return signal, resulting in clearer side, down, and forward imaging.

With a 16V battery, you can identify fish and underwater structures with unmatched precision. This gives you a tactical advantage on the water.

How long will a lithium battery run a fish finder?

The runtime of a lithium fish finder battery depends on its capacity. For example, a LiveScope fish finder requires a power input range of 10-32V, with typical usage at 21W and a maximum of 58W.

A smaller 12.8V 6Ah lithium battery, providing 78.6Wh energy, can power the fish finder for 3-4 hours during typical usage. In contrast, the LiTime 16V 30Ah lithium deep cycle kayak battery offers 480Wh of energy, allowing the fish finder to run for over 22 hours at typical power output.

How to charge the LiTime LiFePO4 lithium fish finder batteries?

Because LiFePO4 lithium batteries have different charging requirements than lead-acid batteries, we recommend using a LiFePO4 lithium battery charger.

Here are the charging options for LiTime lithium batteries:

1. AC-DC Lithium Battery Charger: Select a charger with the appropriate voltage to safely charge the battery.

2. Solar Panels: When using solar panels, always connect a solar charge controller to ensure safe charging.

3. Alternator/Generator:

DC Output: If your alternator or generator provides DC output, you will need a DC-to-DC charger to connect the battery.
AC Output: If it provides AC output, use a compatible battery charger as specified in the product manual to safely connect the battery and generator.

What to do when receiving a new battery?

Upon receiving a new battery:

Charge It Immediately: It likely has a low charge from shipping and storage.
For Bluetooth Batteries Showing 3-5V: Briefly charge for 3-10 seconds using either:

For long-term storage:

Charge the battery to 50% capacity.
Perform maintenance every three months.

Can I connect a fish finder to a trolling motor battery?

Yes, you can connect your 12V fish finder to a trolling motor battery. However, make sure the battery has enough capacity for both devices. For optimal performance, it's best to use LiTime lithium trolling motor batteries, specifically designed for this purpose.

How do I care for my battery when ice fishing?

Caring for your ice fishing battery demands extra attention due to harsh conditions. Always store your battery in a battery box to shield it from moisture and extreme cold. When not in use, keep it in a slightly warmer area to help preserve its charge. Regularly inspect the connections to ensure they’re secure and clean, as ice and snow can lead to corrosion.

What not to do with a lithium fish finder battery?

To ensure the longevity and safety of your lithium fish finder battery, avoid actions that could cause damage. Do not crush, bend, or drop the battery or its charger. Steer clear of using the battery in excessively damp or humid environments, as moisture can lead to damage. Always use a battery specifically designed for your device and ensure it is inserted correctly. Proper care and handling will help maintain the battery’s performance and safety.
