Hey all. I'm tired of lugging around heavy deep cycle batteries for my pontoon. I recently bought a Minn Kota Endura Max 45 lb thrust motor for my pontoon,a Discovery 9. I'd like a battery thats a little lighter that wont break the bank,that will power my motor and give me decent hours of trolling in a morning. Any suggestions? Been eyeballing the agm batteries. I have yet to see a lithium ion that won't cost more than my pontoon and motor! Thanks in advance- Robert
