Case Study: Powering Commercial Fishing Operations with LiFePO4 Batteries

The Serious Recreational Angler

Sep 12, 2025

Customer Profile:
David Chen is a dedicated bass angler who fishes tournaments and weekends on his personal boat. He demanded maximum runtime and stealth but was frustrated by the weight and unreliable charge indicators of his old batteries.


The Challenge:

  • Inaccurate Power Gauge: Poor state-of-charge readings often left him stranded or anxious, cutting fishing time short.

  • Excessive Weight: Heavy batteries made launching and retrieving his boat a difficult task.

  • Inconsistent Power: Voltage sag could lead to less smooth operation at low speeds.


The Haicen Solution:
David powered his Minn Kota Ultrex trolling motor with a 36V 50Ah Haicen LiFePO4 Battery.

  • Precision Monitoring: The Bluetooth-enabled BMS connected to his phone, providing real-time, accurate percentage-based power readings.

  • Dramatic Weight Reduction: The Haicen battery was 60% lighter than his previous setup, making the boat easier to handle.

  • Stable Voltage Output: Provided consistent and silent power all day, even at the lowest speed settings.


The Results:

  • All-Day Plus Runtime: David now enjoys two full days of fishing on a single charge, with power to spare.

  • Complete Peace of Mind: Accurate battery monitoring allows him to focus entirely on fishing, not on his power levels.

  • Enhanced Experience: The significantly lighter weight and utterly silent operation improved his entire time on the water.


Customer Testimonial:
“With Haicen, I finally have a battery that matches my passion. I know exactly how much power I have left, and the all-day runtime is a dream. The weight savings alone was worth it. It’s the perfect partner for a serious angler.” – David Chen

Crikey! Finally, a lithium battery that fits the unique battery trays in our Aussie campervan! The slimline profile was the key for us, but the performance has been equally brilliant. It's revolutionised our off-grid travel around Western Australia.
