NOCO Genius GEN5X1: 1-Bank, 5A Onboard Battery Charger - 5A Per Bank, 12V Waterproof Marine Charger with Overcharge Protection & Temperature Compensation – for Lead-Acid & Lithium Batteries

These work great and will charge my live scope batter overnight. Install is easy and the connectors are very good quality.

I have a 2006 Corvette that I converted to a lithium-ion battery from Braille.When I did this, I wanted to make sure I had a compatible battery tender to make sure the Braille battery would stay nice and healthy during prolonged periods the car is not used. The C6 Corvette is known for battery run-down issues, and I knew this problem would be exacerbated with a lower reserve capacity battery, but I wanted the weight and space savings. I originally had a quick disconnect system in the car, the inconvenience of this became clear whenever I needed quick access to the car, so I decided to install an on-board battery tender.The NoCo unit is very small, and lends itself to being installed in a multitude of locations. The weatherproofing helps a lot, especially if you mount under the hood. I decided to mount inside the rear compartment nearest the battery. This may be an issue for Corvettes with a full-size battery back there, but for me, since the Braille battery was already a smaller footprint, it made fitting everything inside the compartment easy.Long story short, the unit works perfectly. The Braille battery in my car is still healthy and the car hasn't really moved since it's not my primary car. If you're looking for a small tender that can look after a multitude of different batteries (lead acid, AGM, litihum ion), this is the one you want, ESPECIALLY if you're concerned about space and want to mount it on the vehicle in question. NoCo has many other options for garage tenders as well if you aren't interested in mounting on-vehicle, and in my opinion they're the best when it comes to jump starters and tenders. They have many products to choose from, and I highly recommend this unit, as well as anything else made by NoCo. I have one of their jump boxes and the power and footprint are very impressive. I've started equipping all my vehicles and my family with their products.

Can’t go wrong with a NOCO. I use this for my starting cranking battery. I don’t fish everyday so once I’m done fishing I just plug it in to charge and maintain my lead acid starting battery. I also have another one that I bought for my lithium battery for my accessories. Great product, but definitely pay for what you get.

This unit is killer for tending my trailer battery. Easy install.

Permanently installed in the engine bay. Drop the plug by the tire when I'm gone. Zip strip the cord when I unplug. Works great.

I have installed several Noco chargers on various batteries that for the most part sit. They all have worked well and yet to have one fail.

Unit appears to be well made. I used it twice and it seems to be fine. These kinds of products are very difficult to review, especially immediately after purchase. I hope it is good for my new Lithium battery. Again, it seems to be well made and is functioning as expected. The option for use with different types of batteries is nice. It stays on the "type" selected until changed - this is the best aspect thus far.

Very compact and easy to use for multiple types of 12 volt batteries. Installation was easy with self tapping screws. Plenty of cord length to connect to battery and to extension cord.
