Ok guys here is my situation. I have a little 14 foot Jon boat that I have re done and slapped a trolling motor CD player fish finder and lights on. I have a marine battery I bought from the auto parts store it's a marine battery. It will run my fish finder and trolling motor for several hours and then it finally goes. I don't have the option of getting a on board charging system due to my 1950s motor so therefore I'm looking for another battery to supplement what I have im still a young man at the age of 26 with two kiddos running around so going out and buying a 250 dollar battery is not in my budget. Is like to stay around the 120 price range. So any suggestions would help thanks
