Now 20 Watts. Trolling Motor 24V Battery Charger- 1/2 Amp Trickle Solar Charger - Self Regulating - Boat Marine Solar Panel - No Experience Plug & Play Design. Dimensions 14.1 in x 15.7 W x 1/4

Easy to connect and works better than I expected.

So far so good. Only been using about a month but seems to be working on my 24 volt system!

Have used this and another similar panel for my 3 boat batteries (2 for trolling 24v, 1 starting 12v) for a season now and have been happy with the purchase. Store the boat up at the lake without power and these panels keep the batteries topped off in between uses. Works great, waterproof, very easy to install and there are no moving parts. I mounted them to a plywood sheet (and locked with a cable) which I then place on top of the roof during storage to get full sun throughout the day.Only issue I've had is the 24v panel cannot recharge the batteries if run down too far from trolling use. This cannot replace a full powered plug-in battery charger - it's really only a trickle charger than will keep the batteries topped off. If you run them down too far then it will take several weeks to recharge using the solar panel alone or maybe not at all if too far discharged.As we like to go fishing several days in a row, I've had to bring a portable generator with me to recharge after a long day of trolling as the solar panel won't cut it by itself. Still a great option for long term storage or long periods in between use.

I purchased two 24 v charges in early Nov 2015 and installed them Mid Nov to charge two separate banks of batteries used to power two separate 24v trolling motors on a 24-ft pontoon boat. All four batteries have been fully charged for each of 6 fishing trips. I leave the boat on my lake and there is not electrical power to charge batteries. This has saved me removing four 12v batteries for charging at home after each trip. Great device and meets all expectation.

Made a couple of phone calls to them with questions and they took all the time necessary to answer my questions. The panel arrived on time, easy install on my boat. Very pleased with this.

Arrived on time. Was as described. Using it to charge two 24 volt batteries on my boat lift. Working good so far only powered the lift twice since they were installed.

Bought this 20w 24v panel to keep my trolling motor batteries charged and ready for action. As my boat is docked without and electrical within 100 yards, this panel saved my back..... should you need help or advice on you boat needs, the guys at Duravolt are ready to listen..... will be getting one for my cranking battery/ auto bulge pump next.

Very nice, it charges my two 12v batteries for my 86lb. thrust trolling motor. This Solar panel produced 36 volts in the Seattle sunshine. Easily charged my batteries as they are wired in series to make 24.M.Phillips
