Review on 🔌 Solar Maintainer for 2+ Parallel Connected 12V Deep Cycle Marine Batteries - Easy Plug & Play Design | Powerful & Efficient | 14.1" x 15.7" x 1/4" Thick | 10' Cable by Tim Jenkins

Works GREAT as a trickle charger for 2 70Ah lead acid batteries powering my sailboat's electrical system. I leave my boat docked and had to run the engine for a while over the weekend to keep the batteries charged. This completely solves this problem. Now when I get to the boat the batteries are always charged, the engine doesn't need to be started at all. VERY easy to install as this application does not require a controller. The service was great.
