In early 2024, Shenzhen Wirentech Co., Ltd. received an inquiry from a Russian customer who was in search of a highly customized marine battery solution tailored to their specific needs. The customer sought a 12V lithium battery that offered advanced features, including Bluetooth functionality, an IP67 protection rating, an ABS casing, communication capabilities, and an external circular display. The customer’s main goal was to ensure reliable and long-lasting power for their maritime applications, which demanded high-quality performance and robust design.

Understanding the Customer’s Needs: Our team conducted in-depth technical discussions with the customer to fully understand their requirements, including specific performance parameters and the order quantities. With the insights gathered, we prepared a customized quote, offering a LiFePO4 battery pack solution that aligned with their needs. The focus was on providing a 12V lithium battery pack with integrated BMS for lithium-ion battery packs, ensuring optimal safety, efficiency, and performance for the customer’s demanding marine environment.

The Trial Order and Technical Adjustments: After several rounds of technical discussions and product optimizations, the customer placed a small batch trial order in March 2024. During production, our team maintained rigorous quality control processes, ensuring that each LiFePO4 lithium battery met the highest standards for performance and reliability. By May 2024, the customer received their 100Ah LiFePO4 battery units and immediately began a series of in-depth tests.

Issue Identification and Swift Resolution: During testing, the customer identified a significant issue with cell pressure imbalance in one of the 12V lithium batteries, which raised concerns about its long-term performance. Our team acted quickly to investigate the issue and deployed a dedicated technical team to resolve it. After thorough analysis, we pinpointed the root cause and implemented corrective measures to optimize the internal pressure. These adjustments enhanced the overall performance and longevity of the LiFePO4 battery, ensuring that all future units would operate optimally under maritime conditions.

Customer Satisfaction and Repeat Order: The customer was impressed with our swift response and technical expertise, which helped to resolve the issue promptly. This proactive approach not only built the customer’s trust in our products but also reinforced their confidence in our ability to provide reliable, high-quality energy storage batteries. As a result, the customer placed a repeat order in September 2024, demonstrating not only our technical capabilities but also our unwavering commitment to customer satisfaction.

Key Features of the Marine Battery Solution: The marine battery solution provided to the customer was designed with several key features that made it perfect for demanding maritime environments. These features included:

· 12V LiFePO4 battery technology: Offering superior energy efficiency, longer lifespan, and better safety compared to traditional lead-acid batteries, making it ideal for marine applications.

· Bluetooth functionality: Enabling remote monitoring of the battery status through mobile devices, providing the customer with real-time data and greater convenience.

· IP67 protection rating: Ensuring that the LiFePO4 lithium battery is both water and dust-resistant, making it highly durable in the harsh marine environment.
