The Wilson Electric Assist Batteries suit most electric reels on the market. We've put in 18 months of testing these batteries on a range of different reels, just so we could get a real world feel for what they're capable of doing. The internal management system means you can put these batteries under immense stress and they'll not impact the battery's life or the reel. Available at your local retailer now in 3.5Ah, 7Ah and 10Ah. | Wilson Fishing
