I have a new Stowaway marine dual purpose Type st27dp730. I have used it for a trolling motor 3 times at about 30 minutes a time and other than that ive never used it.It's too big and heavy for my yak but great for anyone with a boat, canoe, or a larger kayak. If anyone wants it let me know. Just wanna make a little back. Not much. Im downsizing to a smaller trolling motor battery. Think it was 60 new plus tax. I will take 40 or best offer.
