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

So far so good. Have had zero issues with it charges quickly. Little bigger than I expected but still fits. Good quality

Best charger I've ever bought. 10amp/bank charge rate is much higher than most, has a battery restoration setting that fixed a battery that won't take a charge, and has setting for gel and lithium batteries (I only used it for heavy duty lead acid marine batteries). Almost same price as my 20 year old charger with far less capability; I guess that's tech progress.

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.

Well made excellent product

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!

So many good things about this on-board battery charger. I bought a pair of lithium batteries for the electric trolling motor on my boat. I also bought a battery charger specifically to charge them with. Unfortunatly, after trying various places on the boat, the new charger would not fit anywhere. So, I decided to continue to use my existing battery charger, even though it was not rated for lithium batteries. Should be good enough, right? Wrong. I could only get the new batteries to charge to 69% no matter what I did. Long story short, I purchased the Noco GenPro 10x2 bank battery charger. It was much smaller than my previous new charger, it installed super quickly and it had a switch for charging lithium batteries. Win, win, win. After an overnight charge, both of my batteries were charged 100%. I couldn't be more happy. Wish I could give it a 10.

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.

Compact with tons of power. Doesn't need to charge my batteries overnight takes just a few hours and saves electricity. Highly recommend
