NOCO 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.

Upgraded my mini golf cart with this charger. It had great reviews, the company gives you a 3 year warranty as well. Small and compact. Has Pleanty of length on the leads as well. Charges my lithium ion batteries quickly.

Works great.... It has extended the life of my tractor battery (5yrs old and going strong).

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.

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 purchased this one for my Yamaha 252 boat and loved it. Easy to set up and very well made. Recommended 100%

Working well so far. i may need to upgrade to a 3-bank if things keep going as they are.

This is amazing, replacement of my prior shore power dual charger, due to upgrade to Lithium ion battery for my auxiliary battery in my 1984 VW Vanagon. Paired this with a DC to DC charger and solar controller. Now, my Auxiliary battery will charge while driving, plugged in via this charger and via solar, other power sources are not available. The old lead acid battery was 6 years old, and totally dead after sitting sitting for a few months. The old battery would not change, after trying my other 2 chargers. So, did a temporary hookup with this NOCO and it brought the old battery back to life! Got it to 65%!

Excelente, carrega muito bem as baterias da minha lancha!

Well first impressions this this is a tank solid build that should last for years, I set this up for a duel bank 100ah LiFePO4 battery setup for a garmin kraken. This charging system packs a punch and charges these batteries fast and reliably. It is a heavy well build unit and works for a permanent hardwired setup. Price is expensive but you pay for the quality and reliability dont risk a fire hazard by buying a cheap unit. This is a long term charging system it will save you in the end.

This product is used to charge/maintain charge in my two boat batteries.

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