FPV-Power takes pride in providing the safest, lightweight batteries for kayak anglers. They use the densest, highest quality Japanese Lithium-Ion cells that are currently available. Using these cells allows FPV-Power to provide the kayaker with a lightweight battery power option. Lithium-Ion batteries are lighter, smaller, and last longer than standard lead-acid batteries. Safety is a top priority for this company, and they protect the battery and the angler by encasing the cell in a heavy-duty, and waterproof IP67 rated hard case. Powering your electronics on the water is more important now than ever before. While these battery packs were created with the kayak angler in mind, they are extremely useful in all aspects of outdoor life! Next time you hit the road, make sure you're all set with your FPV-Power battery packs!
