16V Fish Finder Battery

A fish finder battery or battery for fish finder is a specialized power source designed to supply the energy required by fish finders—the devices to locate underwater objects and fishes. A good fish finder battery is built to withstand marine environments, making them suitable for use in boats, kayaks, or other watercrafts. They are also designed to handle vibrations, water exposure, and temperature fluctuations, ensuring reliable performance in outdoor and rugged conditions.

Choosing the right battery for fish finder involves matching the battery’s type, voltage, and capacity to your device’s requirements. Lithium batteries, especially LiFePO4, are the best fish finder battery option due to their longer lifespan, faster charging time, and lighter weight compared to traditional lead-acid batteries.

Next, check the voltage specified for your fish finder, typically in the range of 10V-20V. The common voltages for fish finder batteries are 12V and 16V. A 16V lithium battery, like the Redodo 16V 30Ah fish finder battery, provides higher power output and clearer image than 12V battery, ideal for more advanced fish finders or longer usage. Lastly, consider the battery capacity (measured in Ah), which determines how long the battery will last on a single charge. A higher capacity is suitable for longer fishing trips.

The lifespan of a lithium fish finder battery depends on the type. The Redodo LiFePO4 (Lithium Iron Phosphate) batteries typically last over 10 years with proper maintenance, similar to the RV batteries, offering much longer life than lead-acid batteries, which usually last 2 to 3 years.

The best type of battery for fish finder is a LiFePO4 battery. These batteries typically last up to 10 years, far outlasting lead-acid batteries, which usually last around 2 to 3 years. A 16V LiFePO4 battery, like the Redodo 16V 30Ah fish finder battery, can provide 4,000+ charge cycles at 100% DOD, while a lead-acid battery might only last 300 to 500 cycles. LiFePO4 batteries can charge up to 10 times the speed of lead-acid batteries, and maintain a steady voltage throughout discharge, ensuring consistent power for your fish finder. They are also much lighter, with a 16V LiFePO4 battery weighing about 50%-60% less than a comparable lead-acid battery. Additionally, LiFePO4 batteries are more environmentally friendly, as they contain no harmful lead or acid, making them safer for the environment.

To charge a Redodo 16V Fish Finder Battery, you will need an 18.25V LiFePO4 battery charger. With a 6A charger (0.2C), it takes approximately 5 hours to fully charge the battery. Using a 15A charger (0.5C), the charging time is reduced to about 2 hours. The battery also supports charging by solar panels and a generator.

Redodo 16V lithium fish finder battery differs from a regular car battery. Firstly, the battery for fish finder has a higher voltage of 16V, while car batteries are 12V. Next, a car battery is mainly designed for starting purpose, and the 16V lithium battery is a deep cycle battery designed for long, steady discharges of fish finders. Lastly, similar to marine battery, it’s engineered for marine environments, meaning it’s built to withstand vibrations, moisture, and temperature fluctuations found on boats or kayaks. Fish finder batteries are also resistant to corrosion from saltwater and freshwater, ensuring reliable performance in outdoor conditions.

It is not recommended to use a car battery in place of a fish finder battery. Car batteries are mainly used for starting the car engine, which differs from the purpose of a fish finder battery. On the other hand, car batteries are heavy and bulky, making them unsuitable for boats, especially smaller ones like kayaks. The Redodo fish finder battery like the 16V 30Ah model, offers a lightweight and compact design, weighing only 7.63 lbs and measuring 8.78 × 3.74 × 6.89 inches. It’s a better alternative for fish finder than a car battery.

To maintain your LiFePO4 lithium fish finder batteries, charge it properly using a compatible charger and avoid frequently discharging below 20% SOC. Store it in a cool, dry place at around 50% SOC if not in use. Avoid extreme temperatures, it’s recommended to store the battery between 50°F to 95℉ (10℃ to 35℃). Regularly monitor the battery's voltage. For a 16V LiFePO4 battery, the ideal fully charged voltage is around 18.25V. Clean the terminals periodically to prevent corrosion, especially if exposed to saltwater. Use a battery box for protection if needed. Use a dry cloth or mild cleaner to wipe the terminals and regularly check whether the terminals are securely connected.

To charge your fish finder battery safely, always use a charger specifically designed for 16-volt LiFePO4 batteries, to avoid overcharging or mismatch voltage. Use a charger with overcharge protection. Keep the terminals clean and dry, and make sure all wires are properly connected before charging. Charge in a well-ventilated area to dissipate heat and avoid near flammable materials during charging. When fully charged, disconnect the charger in time.

The primary difference between a 16V and a 12V fish finder battery lies in their voltage stability and how it impacts the functionality of your fish finder.

A 16V lithium battery, like the Redodo 16V 30Ah fish finder battery, maintains a steady voltage above 15V for its entire discharge. This consistent voltage ensures the fish finder runs smoothly, delivering accurate sonar readings, faster map loading, and clearer imaging. It helps to locate fish and underwater structures effectively.

On the other hand, a 12V battery for fish finder is prone to voltage drops during use, which may affect your fishing experience. For example, the sonar may become less accurate, images may distort, and the device may lag, all of which can lead to missed opportunities to spot fish or identify underwater hazards.
