Cotech DN-1700NS 14000mAh 14.8V Lithium Battery & Charger Set for Shimano & Daiwa Reels

All-day power for serious anglers on and off the water

The Cotech DN-1700NS combines smart design with robust energy. With a 14,000 mAh capacity, this portable lithium battery delivers extended power to support high-demand electric reels from top brands like Shimano and Daiwa. Its compact form conceals a generous energy reserve, designed to keep you fishing longer between charges while maintaining responsive reel performance.

Engineered for real-world use, the DN-1700NS weighs about 1.2 kg and measures 213 x 104 x 45 mm, a size that fits neatly in a bag or boat space without feeling bulky. The system operates at a nominal 14.8V, with a peak range up to 16.8V, which can translate to faster winding compared with standard batteries. This combination of high capacity and ready-to-use voltage makes it a practical companion for deep-water jigging or long offshore sessions where reliable power matters.

Real-world use cases

Imagine a day on calm seas where the focus shifts from power management to the action of the catch. The DN-1700NS supports extended sessions, allowing you to fish for hours without frequent recharges. For deeper jigging or power-hungry reels, the battery’s large capacity helps you stretch your trip while maintaining reel performance when the moment counts.

• Two USB ports let you keep smartphones, GPS devices, or LED lighting powered throughout the trip.
• Rugged and portable, the unit ships with a carry bag and an English manual for quick setup and transport.

What to know before you use it

Key usage notes help you get reliable results. The USB port includes a rubber cap to protect against debris, but it is not waterproof. When used on a boat, consider additional protection against seawater exposure. The package includes the battery body, charger, carry bag, and an English manual with a 90-day warranty; the power cord to connect to the reel is not included.
