Genius GENPRO10X2: 2-Bank, 20A Onboard Battery Charger - 10A Per Bank, 12V Waterproof Marine Charger with Overcharge Protection & Temperature Compensation – for Lead-Acid & Lithium Batteries

I purchased a new to me boat that has two batteries. I had an onboard charger on my last boat that worked great. I didn't get the same one because I found this one from NOCO. They just make solid stuff. So I went with this and haven't regretted it. I also purchased the cable connector that allows you to install it in the bulkhead and simply run an extension cord to the connection. Keeps it very clean and professional. This charger, however, works like a champ. Provides plenty of power to keep my batteries charged and with 10A per battery, it supplies enough power to recharge a battery from dead quickly. It's just a very solid device. Easy to install and just plug and play.

Love this charger for my trolling motor batteries. Two 10A chargers that supports 12V, 12V AGM, and most importantly 12V Lithium. Unit is bullet tough and looks like it should last for years (I hope). Super easy to use and charges fast. Not sure what else to say other than just buy it, you will love it.

Excellent

I was using this system to charge two lead batteries and now I am switching to a lithium in my boat. the value of it and use is makes it super easy to use and offers a great charge. it gives options to charge lithium which when I bought was not really looking for but glad it has the feature. it is pretty bulky and a bit heavy but for what is is doing its working. have had no issues leaving it plugged in for a two days

I bought two of this for my boat. It is nice to have chargers that work for all battery types I would ever use in my boat. I just upgraded to lithium ion batteries for my trolling motor and repositioned them to the front of the boat for weight distribution. I use the other charger for my cranking battery and another lithium ion battery for graphs etc. nice to just plug them in and know they will be ready for use next time on the water.

This is the last battery charger you will buy. Just purchased a second unit for my numerous motorcycle, car, AGM, GEL Cell and Lithium batteries. This charger does it all. You can't buy a better unit. In over 45 years in working on cars, this is the highest quality battery charger I have found. You know what they say, you get what you pay for. Go for it, you're worth it!

I bought this after my Boat onboard charger stopped working 5 months ago in June without my knowledge, both of my Group 31 AGM batteries were completely dead. When I saw this unit and read the performance features that included charging Ni-Cad, AGM AND lithium batteries plus a feature that would restore completely dead batteries I decided too try this battery because I have bought 3 jump start units from NOCO with good results. I installed this unit and plugged it in and after 30hrs my bank 2 battery was completely charged. My bank 1 battery had know indication of any charging, so I thought I would be buying a replacement battery. Then I remembered this unit had a restore dead battery feature so a switched the unit to restore for bank 1. After another 10hrs bank one battery was at 80% after another 12hrs bank one was at 100%. I did a load test by running my electric trolling motor for 4hrs at 90% power the batteries never stopped giving power with the trolling motor dropping too approximately 40/50%. I plugged the charger up again and obtained 100% charging on both batteries.

The electronics seems to be well packaged and it's heavy. Both POS and NEG leads seem to have fuses, great. The documentation is terrible, I downloaded the PDF and it's formatted like the physical manual very wide, super hard to read even on my PC. Make sure you call NOCO and get the latest interface because the default LEDs and labels present a mediocre user experience. See the upgraded one attached.

Funciona muy bien Carga. Rápido las baterías , continuare actualizando como funciona, A mas largo plazo

Amazing product, charges my batteries quickly and it's sturdy

I had a hardwired charger before and this unit dose not have that option so I had to add a waterproof box for the line voltage connection, didn't want to cut the plug off as I'm sure this would void the warranty, the cables for the batteries were also too short for my desired location. Besides that, its pretty slick. Plug and play.....I get it, its waterproof so the connections are all sealed. Would of been nice if they had a hardwired version though. For the price you cant go wrong. My other unit was 4 times the price so this is still a rocking deal. The unit is very tiny and looks pretty. Charges both banks with no problem. Definitely recommend.
