The Next Evolution of Electric Fishing Reels: Why Custom Lithium Battery Packs Are Becoming Essential

Behind every high-performance electric reel lies one critical component: the battery system.

More brands are now shifting from generic batteries to fully customized lithium battery solutions. PKNERGY is
proud to support this global shift by helping brands build advanced, reliable, and user-centric battery systems
designed specifically for modern fishing applications.

01｜Why the Battery Determines an Electric Reel’s Success

Electric fishing reels must perform reliably in harsh, unpredictable environments. They face:

• Heavy pulling loads and rapid torque spikes
• Constant vibration from boat movement and line tension
• High humidity and saltwater exposure
• Long fishing hours during offshore trips
• Frequent start-stop operation and power bursts

These conditions make the battery the most critical component of the entire system.

A poorly designed battery can cause:

• Power drops during heavy load
• Weak pulling force
• Overheating and internal damage
• Corrosion and poor contact
• Short runtime and interrupted fishing
• Negative user experience and returns

A well-engineered battery, by contrast, ensures strong performance, safety, consistency, and long-term
durability—even in tough marine environments.

02｜Why Generic Batteries No Longer Meet Market Needs

Generic batteries are not designed for marine conditions or modern electric reel performance targets. They often
suffer from:

• Incompatible voltage and insufficient output power
• Poor connectors not optimized for reel interfaces
• Weak protection systems and basic BMS
• Limited runtime and unstable performance
• No resistance to salt fog, corrosion, or splashes
• No brand differentiation or premium feel

Custom lithium battery packs, however, are engineered specifically for fishing and marine use, offering:

• Tailored power output and discharge curve
• Marine-grade durability and sealing
• Optimized runtime for long-hour fishing trips
• Lightweight pack design for easier handling
• Fully compatible connectors and wiring
• Brand-exclusive form factor, color, and design
• Enhanced safety and reliability

With a custom battery, an electric reel is transformed into a premium product with stronger market
competitiveness and higher user satisfaction.

03｜PKNERGY’s Engineering Approach to Custom Battery Solutions

PKNERGY collaborates with fishing reel manufacturers worldwide to deliver end-to-end custom battery solutions.
We design systems that align with:

• Product strategy and market positioning
• Electrical and mechanical requirements
• Target fishing scenarios and environments

Our development paths include:

• Ultra-Light Portable Series – For anglers who need compact, easy-to-carry packs.
• Extended Runtime Premium Series – For long-hour offshore and deep-sea trips.
• Deep-Sea High-Power Series – For powerful electric reels handling heavy lines and big fish.
• Commercial & Boat-Use Series – For charter boats, rental fleets, and professional users.

We also support custom housing, color schemes, branding, and packaging so that the battery pack looks and feels
like a natural part of your product ecosystem.

04｜Custom Batteries as a Strategic Business Advantage

Custom battery systems improve more than just technical performance—they enhance brand trust, reduce after-sales
issues, and help justify premium pricing.

Key business advantages include:

• Higher customer satisfaction and loyalty
• Fewer failures, returns, and complaints
• Stronger, more recognizable brand identity
• Better product reviews and word-of-mouth marketing
• Greater competitive edge in global markets

A better battery improves the entire product experience, helping reel brands expand globally with confidence and
build long-term value.
