Fish Finder Batteries

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. These batteries are 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.

The best type of fish finder battery is a LiFePO4 battery. These lithium batteries typically last up to 10 years, far outlasting lead-acid batteries, which usually last around 2 to 3 years. Redodo fish finder batteries, like the 16V 30Ah fish finder lithium 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, 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.

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 lithium fish finder batteries are 12V and 16V. A 12V fish finder battery, like the Redodo 12V 20Ah lithium battery, offers a lightweight and compact size, while a reliable power. A 16V fish finder battery, like the Redodo 16V 30Ah lithium 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 Redodo fish locator batteries are compatible with most major fish finder brands, including Humminbird, Garmin, Lowrance, Vexilar, and more, ensuring reliable and long-lasting performance.

Redodo lithium fish finder battery differs from a regular car battery. Firstly, our 16V 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 our battery is a deep cycle battery designed for long, steady discharges of fish finders. Lastly, similar to marine battery, it’s IP65 waterproof rating and engineered for marine environments, meaning it’s built to withstand vibrations, moisture, and temperature fluctuations found on boats or kayak. They 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 locator battery. Car batteries are mainly used for starting the car engine, which differs from the purpose of deep cycle battery. On the other hand, car batteries are heavy and bulky, making them unsuitable for boats, especially smaller ones like kayaks. The Redodo kayak fish finder batteries, such as the 16V 30Ah model, offers a lightweight and compact design, weighing only 7.63 lbs and measuring 8.78 × 3.74 × 6.89 inches. The lightweight and compact design makes it ideal for powering the fish finder on kayaks and small boats.
