Client Background
• The client manufactures portable fish finders for recreational anglers using small boats, kayaks, and shorelines.
• Their users expect reliable sonar performance and clear displays for a full day of fishing, without carrying bulky external power sources.
• Early designs using generic battery packs delivered limited runtime and unstable performance at low state of charge, especially in cold weather.
• The client also needed a more robust, integration-friendly battery solution that could support water-resistant enclosures and withstand frequent outdoor use.
Battery Solution
• Himax Electronics designed a dedicated 7.4 V 5000 mAh LiPo battery pack for portable fish finders, with size and capacity customizable for different models.
• The 2S LiPo configuration provides a stable voltage to power sonar transmitters, displays, and wireless modules, with enough capacity for all-day fishing sessions.
• An integrated protection circuit offers over-charge, over-discharge, over-current, and short-circuit protection, while reinforced leads and waterproof-ready connectors support higher enclosure IP ratings.
• Himax collaborated with the client’s mechanical team to optimize the pack outline so it fits tightly inside the housing, reducing thickness and simplifying assembly.
Benefits & Market Feedback
• With the Himax 7.4 V 5000 mAh battery, the fish finder delivers significantly longer operating time at typical brightness and sonar settings, even in low temperature conditions.
• End users report they can stay on the water all day without worrying about power, and device performance remains stable as the battery discharges.
• The brand now promotes extended runtime as a key feature in its marketing, strengthening its position in the fishing electronics segment and driving sales of both main units and spare battery packs.
