How to Choose an Electric Fishing Reel Battery: A Complete Guide to Selecting the Right Battery Pack
29/11/2019Fishing enthusiasts know that when using an electric reel, it’s essential to have the correct battery. Choosing the wrong battery could result in a mid-trip power failure, turning your exciting, anticipated fishing adventure into a disappointing experience; with the differences in performance between lithium and lead-acid batteries and numerous brands like Shimano, Daiwa, and Ecooda, deciding which one to choose can be unclear.
To help, we’ve created a popular Electric Reel Battery recommendations list and buying guide. This guide covers battery types, capacities, compatibility, and more so you can fully understand how to choose the best Fishing Battery for your needs. Whether you’re looking for a high-capacity option for extended fishing trips or a compact, portable battery, we’ve got you covered. We also recommend matching Daiwa and Shimano electric reels with the perfect battery. Equip your electric reel with the ideal battery and enjoy a comfortable, hassle-free fishing experience!
Why Do battery electric reel a Dedicated Battery?
Power sources for electric reels generally come in two modes: boat power (directly supplied from the boat) and self-supplied batteries. However, boat power often fails to allow the electric reel to perform at full capacity because the voltage fluctuates due to other anglers on the boat using power. The more people using the boat’s power, the more noticeable the voltage drop becomes, which can lead to slower line retrieval or even sudden power failure!
For this reason, most anglers nowadays opt to bring their own portable fishing reel battery on board for a smoother fishing experience. Anyone who’s used an electric reel knows that proper battery matching is crucial, as regular batteries can’t handle the high load demands of the reel. A suitable electric reel battery ensures uninterrupted fishing, especially in the deep-sea fishery where the reel motor needs continuous high-power drive.
Here are six key factors to consider when selecting the correct electric fishing reel battery:
1.Voltage and Current Compatibility
Electric reels require specific voltage and current. Dedicated batteries are designed to match these parameters precisely, ensuring stable performance. Generic batteries (like regular alkaline batteries) may provide insufficient or unstable voltage, potentially damaging the motor or causing malfunction.
2.Battery Life and Energy Efficiency
Dedicated batteries are optimized for low-power, intermittent use by electric reels, offering longer battery life. For instance, lithium or nickel-metal hydride (NiMH) batteries are designed for high capacity and low self-discharge, making them ideal for extended standby use.
3.Size and Installation Compatibility
Electric reels have limited internal space, so dedicated batteries are designed to fit the reel structure, ensuring seamless installation. Generic batteries may not fit properly, resulting in issues with securing them or affecting the reel’s appearance.
4.Charge and Discharge Cycle Life
Dedicated batteries’ chemistry and charge/discharge management (e.g., lithium battery protection circuits) are optimized for frequent use, like daily reeling in and out. Generic batteries might not handle frequent charging and discharging, reducing their lifespan.
5.Safety Features and Protection
Dedicated batteries often come with built-in protection circuits against overcharging, deep discharge, and short circuits, ensuring safety by preventing overheating or leakage. Generic, cheaper batteries might lack these safety measures.
6.Communication and Smart Control
Some advanced electric reels (such as innovative models) require communication with the battery (e.g., battery feedback). Dedicated batteries may integrate communication protocols, whereas generic batteries typically do not support such functions.
Choosing the right electric reel battery will ensure your fishing experience remains smooth and enjoyable, with no interruptions when you need it most!
What Are the Main Types of electric fishing reel battery?
Currently, the most commonly used dedicated electric reel battery pack are lithium-ion batteries and lead-acid batteries, each with distinct differences in power performance and price.
Lithium-Ion Electric Fishing Reel Battery
Voltage: Typically 12V-14.8V/16.8V
Capacity: Ranges from 2000mAh to 25000mAh
Advantages:
Lightweight and compact
High energy density
Fast charging (some models fully charge in 1-2 hours)
Ideal for high-end electric reels like Daiwa and Shimano
Best For: Anglers looking for portability, quick recharge, and high-performance power for demanding electric reels.
Lead-Acid Battery
Voltage: Typically 12V
Capacity: Ranges from 5Ah to 20Ah
Advantages:
More affordable

Choosing the Right Electric Fishing Reel Battery pack
When deciding between lithium-ion and lead-acid batteries, consider weight, size, power output, battery life, and charging time. These considerations will help determine which type of battery best suits your specific fishing needs.

How to Determine Compatibility of a Battery Electric Reel?
Key parameters to consider include:
Connector Type; Voltage Matching; Battery Discharge Current
It is recommended to choose battery electric reel products labeled as “Compatible with Shimano/Daiwa” to avoid issues like mismatched connectors or voltage differences, which could potentially damage the reel.
Common Mistakes When Buying a Battery
❌ Only Focus on Capacity, Not Discharge Efficiency
❌ Cheap Batteries Lack Safety Protection Circuits
❌ Neglecting Compatibility of Battery Connectors
Summary & Recommendations
Choosing the correct electric reel battery not only affects your fishing efficiency but also impacts the lifespan of your electric reel. When deciding, consider factors such as the brand (e.g., Daiwa), fishing duration, and compatibility. Prioritize genuine brand batteries or those with a good reputation for reliability and performance.
