Hey guys I got a 14 foot aluminum that I got a trolling motor for and I need a battery to power to motor lights bait pump and fish finder. I've heard nothing but good things about Optima batteries and want to go with that but not sure what to get? Also where should the battery be in the boat? Can it be in the back of the boat next to gas tank or is that big no no? Might be stupid question but it's my first boat so I'm still learning g . Thanks guys!!
