Victron EnergyBlue Smart IP67 Smart Marine Battery Charger 12V 7A, Float & Trickle Charger and Desulfator for Boat, ATV, RV, Lithium and Deep Cycle Batteries

I have purchased two of these chargers. One for my big boat for charging my two lithium batteries (in parallel) and one for my 73 oldsmobile. The blue tooth function is awesome so you can see from your phone the charging cycles, how deep the last discharge was, and battery health. Note: you must set up what type of battery it will be connected to! This is done via the Victron app for your phone (free).

I have now purchased 3 of these and they work great, I have used many different charges and these so far are the best. The app works great and lets me see the condition of the battery.

I seldom use my truck. I put on maybe 4,000 miles per year and that's counting a trip from Miami to Georgia once a year. My problem is I have accessories that constantly drain power and they kill the battery if I don't use a battery charger. USB devices, the radio, truck computer, etc. This charger keeps the battery topped off without cooking the battery. Plus it has a cool Bluetooth feature so you can see the state of charge at any time. And it's IP67 waterproof. I'll probably change all my Noco Genius chargers to Victron, especially my boat.

Works fine for my inboard engine starter battery.

Simple to use, worked for my AGM battery, car battery, and LFP battery. I even had a BMS cut-out on my LFP battery, and this charger was able to revive it. Nice to be able to customize settings and monitor performance with the bluetooth app.

Good quality! Bluetooth function helps a lot control and monitoring the device.

I bought this to charge my RV batteries through the provided Furrion port on my trailer. The Furrion port is only rated for 10 Amps (and has a 10-amp fuse). This charger provides around 7 amps so I'm not in danger of blowing the Furrion fuse. It also does LiFePo4 batteries and brings them to full state of charge. I did have to make an adapter to go to the Furrion port or to battery terminals. I've gone through about 5 charge cycles with this so far and it works well. I have basically disconnected my trailer internal charger and instead charge with either solar or this Victron charger.

First, this thing is not cheaply made and you will know that the moment you touch it.Feels like a solid hunk of metal, nothing lose inside, no noise if you shook it. Completely sealed and can be mounted outside or in an engine bay or whatever.No fan, and NONE NEEDED. Without a fan, this beast still barely gets hot. After running this charger for hours, it is still cool enough for an infant to touch. The Bluetooth app is a huge plus and makes monitoring effortless, and from your phone.The unit updated its firmware without hiccup and was up and running in a few quick minutes after unboxing.Victron products are 5 star, if you can afford the. Warning though, once you get started with their products, you will probably go down the victron rabbit hole of amazingly great products; but it's costly.Hands down 5 star charger that you don't have to worry about a cheap Chinese charger starting a fire.
