Deep Cycle

A trolling motor battery’s capability to deliver a full cycle and achieve a full charge again what makes it stand out from most batteries.

What to Look For

DeepAh/Ampere Hours

The more ampere-hours your battery has, the longer it can power your motor.

If you have a big boat and you aim for deep-water fishing, then you will need a high-power rated battery. With regards to low-water fishing, a high amount of power will be excess. 

Design and Construction
