UPGRADED DuraVolt Blue 24V 60W Trolling Motor Charger - 2A Solar Battery Charger for Boats - Plug & Play Waterproof Design - Perfect for Marine, Fishing & Outdoor Power Supply

This is the best solar panel available for keeping your 24 volt trolling motor battery system charged 100% between plug ins. My boat sits in a marina with no shore power. I usually fish the weekends utilizing my terrova 24 volt trolling motor. After fishing the weekend my batteries are down to about 55%. I use this solar panel during the week while my boat is sitting in the marina and when I return to fish the next weekend my batteries are 100%. No lugging generators no bull the sun is free. If you call the customer service number a real person answers who is a great guy with a wealth of knowledge about solar and batteries. I called him before I purchased and I was sold after talking to him. After one year of use I couldn't be happier I highly recommend this product.
