Tangled cables, scattered batteries, and loose gear can turn a simple setup into a headache - but the Firefly Marine Shorestacker Box keeps everything locked down and ready to roll. Designed for anglers who need a reliable storage and power solution, this rugged box features a top tackle compartment for quick access to essentials, while the spacious lower section secures larger gear and power tool batteries from 12V to 30V. A custom foam insert prevents shifting, keeping batteries snug and secure on the move. The latching on/off switch lets you easily control your Firefly stern light, providing hours of non-blinding illumination with minimal bugs. Built tough for life on the water, the Shorestacker Box keeps your gear organized, powered, and protected - so you can focus on fishing, not fumbling with your setup.Dual storage compartments - top section for tackle, bottom for larger gear and batteriesWorks with any 12V to 30V battery for extended useLatching on/off switch easily controls a Firefly stern light for hours of non-blinding illuminationCustom foam insert secures batteries in place and prevents shifting during transport
