Humminbird 15Ah Lithium Battery Kit

The Humminbird 15Ah Lithium Battery Kit (MPN 770032-1) is a dedicated power solution designed for Humminbird portable and ICE fishing systems. This compact lithium battery delivers reliable energy density in a lightweight 3.6 lb package, making it ideal for anglers who need extended runtime without the burden of heavy lead-acid alternatives. The 15Ah capacity provides sufficient power for multiple days of sounder operation, critical when you're targeting panfish under winter ice or fishing remote inland waters where recharging isn't readily available.

The kit includes dual USB ports, allowing you to keep your mobile devices, GPS units, and other field electronics charged while operating your sounder—a practical consideration for weekend fishermen and serious ice anglers alike who rely on smartphones for weather updates, navigation, or communication. The integrated LED battery level indicator eliminates guesswork during outings, letting you monitor remaining charge at a glance and plan your fishing session accordingly. Lithium chemistry also offers superior cold-weather performance compared to traditional battery types, maintaining consistent voltage output even in sub-freezing conditions typical of northern ice fishing environments.

This battery kit is engineered for anglers operating Humminbird HELIX, SOLIX, or other compatible portable sounder models. It's particularly valuable for ice fishermen who fish multiple holes or move between locations throughout the day, as the weight and runtime balance it provides exceeds what alkaline battery packs or single-use power solutions can deliver. The one-year limited warranty backs the product against manufacturing defects, providing confidence in a critical piece of fishing equipment. Whether you're jigging bluegill through early-season ice or running sonar scans in fall before the freeze, the 15Ah lithium battery kit ensures your electronics don't become the limiting factor in your fishing day.
