FAQ for Fish Finder & Portable Sonar Batteries
A: This depends on your device’s screen size and power consumption. We will design the battery with a specific Watt-hour (Wh) capacity to meet your target runtime, whether it’s 8, 12, or even 24+ hours.
A: Yes, absolutely. We use a specialized wide-temperature chemistry that is engineered to perform reliably in sub-zero temperatures, which is essential for ice fishing electronics.
A: We can design the battery pack with a fully sealed, robust housing to achieve a high IP rating (e.g., IP67). This makes our battery a key component in your overall waterproof product design.
A: For a new custom design, our MOQ typically starts at 20,000 to 50,000 units, depending on the complexity of the housing and electronics.
A: Yes. We design our packs to handle the continuous power draw from modern, high-power screens and powerful sonar transducers, providing a stable voltage for clear, flicker-free operation.
A: After the design is finalized, the lead time for the first batch of ruggedized prototypes is generally 6-8 weeks.
A: Yes, we can design the battery pack to be user-replaceable with a durable enclosure and secure connectors, allowing customers to carry a spare for multi-day trips.
A: We can design the pack with a standard DC barrel jack for charging with an AC adapter. For smaller, castable devices, we can integrate a USB-C port for convenient charging.
A: Yes. We manage the entire certification process to ensure your battery pack meets all required standards for your target markets, including CE, UL 2054, IEC 62133, and UN38.3.
A: Please provide your device’s voltage, required runtime (hours), continuous power draw (Watts or Amps), dimensional constraints, any specific IP or temperature requirements, and your estimated annual volume.
