With everyone praising the duracell agm batteries they get at SAMs wholesale I decided to try a set for the trolling motor. Found a little better deal on the warranty at batteries plus instead of going with the SAMs version. Side by side they are essentially the same but with a different sticker. 30 month warranty at battery plus, plus a business discount I paid a few dollars more than SAMs. I'll dig this post back up in a few month to report my experience.
