I used this charger to replace my 30amp converter in my RV . I wired in a female plug into the ac side . So far it’s working perfectly. I love the fact that I could set it up to charge my lifepro4 battery to specs .

Love the bluetooth option. Would like to be able to turn on and off remotely, but that's okay. I also wish they made a higher amperage one that I could run everything through to monitor all the usage. No complaints though. Well built and works great!

Can also be used in a power supply mode with a settable current limiter. A super useful feature!

This does in fact does charge and maintain batteries. Easy to install and set up via Bluetooth. However, very disappointed that it does not communicate with my Cerbo GX to verify how well it is maintaining my battery system. Otherwise great device.

Ties in nicely with my other Vicitron products. Solid build, fool proof operation, Bluetooth connection works nicely.

I've purchased several LiFePo4 chargers in the past, and this 30A version by Victron Energy has far exceeded my expectations...First, It is truly a 30A charger. I measured 26.4 A output while charging a 100Ah LiFePo4 battery that had been discharged to roughly 50%. Within 2 hrs. the battery was fully charged. Second, there are two precise charging voltages available for LiFePo4 and lithium batteries (14.2 and 14.7) None of my other charges offer this feature. Third, and something none of my other chargers are capable of; It can be used as a DC power supply without being connected to a battery. (Pic showing an off-road lamp being powered directly) This feature is clearly stated in the owners manual. "Victron Energy definitely listened to their customers when they engineered this product!"All of my batteries are rated at 14.4 VDC maximum charge input. Setting the unit to 'Lithium' fits their requirements perfect. Without a load, the unit puts out exactly 14.3 VDC.A heavy 120VAC power cord comes attached to the unit. However, the end user must supply the output conductors and connection type. "Just pop off the small cover at the front of the unit and attach using the pre-installed terminal blocks."Build quality is excellent. There's absolutely nothing 'cheap' about the chargers construction. This Victron Energy product may cost a bit more than other similar chargers out there, but you seriously get what you pay for from this company. If I could rate this product at ten stars, I'd try to give it a fifteen. Yep... "It's that well made."It's also backed by a FIVE YEAR warranty. "That's something that is seldom, if ever offered on an electrical device. Kudos to Victron Energy for backing their products with such a long warranty!"

Great charger with the ability to set up custom profiles. The reason for only 4 stars instead of 5 is for the very poor bluetooth range, keeps loosing signal 10 feet away. Other that that it is a great charger.

This review looks at the charger more from an automotive use case, and not from the RV/off-grid/solar use which the charger is actually targeted towards, so keep this in mind as you read.I purchased this charger as a replacement for my Noco Genius G26000 26A 6v/12v/24V charger, as I needed a charging solution for my new Northstar AGM battery which would allow me to meet the exact charging specifications provided by the manufacturer. I was looking for a fully-featured charger that would provide a level of adjustability that allowed for a charging profile in line with the instructions provided by the manufacturer to ensure maximum performance and longevity from the battery. Lesser chargers tend to use a "one-size-fits-all" approach when it comes to their charging profile, meaning that certain parts of the charging profile will not be in agreement with the charging instructions provided by the manufacturer of your expensive batteries, while other manufacturers (cough...Noco.....cough) refuse to discuss their charging algorithm and instead recommend that you purchase one of their chargers to see first-hand using test equipment whether their charger is right for your battery. To save you some time, money, and frustration, Noco chargers are not approved chargers for Odyssey or Northstar Thin Plate Pure Lead AGM batteries due to the peculiar charging algorithm and charging features they use.Interestingly enough, this charger is marketed toward the RV/off-grid/solar crowd, and not so much the automotive genre, as evident by it only charging 12V batteries, but a look through the specs and attributes of the charger quickly convinced me that it is a much better 12V battery charger than most high end automotive chargers from CTEK and Noco - namely the Pro25 from Noco and the Pro25S from CTEK for charging 12V batteries. With that said, this charger is not a ready-to-run affair, as it requires you to make your own charger->battery connection (as you will see in the attached pictures). If you are mechanically inclined, and have a few tools, this won’t be an issue.The charger is available in several models, with various charge outputs and battery outputs(12V - 8A, 15A, 20A, 30A with 1 or 3 outputs; 24V - 8A, 12A, 16A with 1 or 3 outputs). I selected the 12V single output 30A model since I only charge one car battery at a time. For my charger to battery connection, I opted to go all out, and used 6 AWG welding cable (for minimum electrical resistance), wire loom, ferrules for the connection at the charger, as well as 50A Anderson connectors for my battery end. You definitely don’t have to go this fancy, but I was trying for a setup that can easily and quickly be disconnected from the car when I want to use it, and also quickly and easily reconnected when not using the car. You can opt for something much simpler, using a thinner gauge of wire as well as skipping the Anderson connectors. With that said, you want to ensure that whatever wire you use can support the output of the charger at the length you are using and has a proper connection to the charger in order to prevent heating the wires or even the device up due to excessive voltage drop.In addition to the above, I also picked up Victron’s Smart Battery Sense device. This little box attaches directly to the side of the battery, and provides via Victron’s specialized network connection to the charger, info relating to the actual voltage and battery temperature. This is information that will come in handy as described later. It is important to note that the charger can work without this attachment, but it becomes more important depending on how accurate you want to get with charging and maintaining your battery. It also broadcasts battery voltage and temperature via bluetooth, which means you can see what your battery voltage is at home from the comfort of your bed (if you were so inclined). In addition, the app provides live voltage readings over time on a graph which you can zoom in on, allowing you to see details such as how low your battery voltage drops during engine cranking, or even see what voltage the battery is seeing from your alternator while the engine is running. etc.The Victron IP22 charger out of the box has 4 modes that you can select - Normal (14.4V for flooded batteries), High (14.7V for AGM batteries), Recondition (for stabilizing the cells of the batteries… more a flooded battery feature), and Li-ion. If you decide to use the Victron Connect App through your smartphone, you can access a whole world of other features that quickly separates this charger from the aforementioned CTEK and Noco chargers aimed at the automotive space. The charger gives away the fact that it is targeted towards the Recreational Vehicle crowd through its “Night Mode”, which drops the charger output to a maximum of 15A and disables the internal fan in order to keep the charger silent; Ideal for not being disturbed by a loud charger fan while you sleep inside your RV!Just some of the things the app allows you to do is to select a charge profile for your specific make of battery, be it a Northstar battery TPPL, Odyssey TPPL, Life Line AGM, Battleborn Lithium, and other popular batteries used by the RV community for battery banks. If a profile does not exist yet for your battery, you can either edit an existing profile with data provided by the manufacturer of your battery and name it differently for your use, or you can cook up a new profile from scratch for your make of battery (this in essence allows you to cook up a profile for almost any kind of 12V battery be it lead acid or Lithium). You can select what bulk voltage the charger uses, absorption voltage, float voltage, and even if you want it to attempt to “recondition” your batteries during the charging phase, or enter a “storage” charge phase at the end after maintaining float for a number of hours (which again you can program). The level of adjustability is simply amazing. In addition, the charger will store telemetry from 40 charge cycles, which will allow you to go over historical data relating (and not limited to) items like how many amp hours were put into the battery at any part of any charging process, how long the battery was on bulk charge, absorption charge, float charge, reconditioning, charge voltage offset, and more. You can select how long the charger will allow the charger to bulk charge for (again, these are specs that battery manufacturers often provide to ensure maximum performance and longevity), and even what amp input you want the charger to switch from Absorption to float mode. These are all items that the high end Noco or CTEK do not allow you to control.The app also allows you to create a special wireless Victron Network on which other products from Victron can connect to communicate with each other. In my case, the aforementioned Smart Battery Sense device I purchased communicates battery voltage and temperature directly to the Victron charger wirelessly. This allows the charger to account for the effects of voltage drop on the wires and connectors and provide the correct charging voltage offset for the battery depending on temperature. This way, you ensure that the battery is receiving the exact prescribed voltage and current at all times and temperature conditions. You can even see just how much voltage drop your connection is causing through the app (with my 6AWG setup, I get 0.02-0.03V of voltage drop) between the charger output connectors and the battery terminals. This low voltage drop ensures that more of the correct charging current at any given time actually goes to the battery and not into heating up the wires (as could be noticed with the thinner wires on the Noco G26000 charger). In my use, even when charging at 30A in bulk phase, my charger always stays cool to the touch and silent.The app also allows the charger to be used as a power supply, providing up to 30A of support at a constant voltage set by the user. This allows you to run subsystems on your car at a constant voltage without depleting your battery. On my car, I use this feature for testing out my fuel system, ignition system, different fluid pumps, and programming the ECU, and could even use it to power my sound system and head unit for as long as I wish without depleting the battery. This is perfect for use at car shows for keeping certain elements of the car powered without draining the battery.No item out there is perfect, and there are a few improvements I would suggest, if I could:- There is no “standby” mode on the charger. The only way to interrupt the charging process is by pulling the plug on the device at either the battery or at the wall outlet or disconnect the charger leads from the battery (this is where the Anderson connector I used comes in handy).- The charger has no mounting feet underneath it. You get the distinct impression that Victron intended for users to mount the charger on a wall vertically, and equips the charger with mounting tabs through which screws would go. If you wish to use rubber feet instead, you would need to do the leg work to acquire these yourself.- Minor thing, but no carry case or bag is included with the charger. Not a massive deal, given the price of the charger, and its real target audience, but still… a bag/case would have added to give a premium feel to the charger… but then again, the charger does not have the premium price of the CTEK or Noco chargers, and is marketed toward RV/Off-grid/solar types, and not so much the automotive crowd. Perhaps something to consider if they decided to go after the automotive market where Noco and CTEK play.- You might need to be mechanically inclined in order to get everything working. Some wiring is required (i.e. making the charger->battery connection).- This particular version of the charger that I have works on 12V batteries only, so if you need to charge a 24V battery, you will need to select the 24V version of this charger. Again, depending on what you are using the charger for, this may or may not be a problem at all. There is no 6V version of this charger available.- The IP22 rating for water resistance means that you won't want to use this charger outdoors. Use and install it in a dry area away from water. Other chargers in the automotive space such as the Pro25 Noco and the Pro25S from CTEK have a higher waterproofing rating. Again, this is the charger telegraphing its target audience - installations within RVs where it is not likely to be exposed to the elements .Aside from these minor niggles, I’ve been happy with my purchase so far, and will update things if there are any changes. The 5 year warranty and extensive dealer network that Victron has gives me confidence in the long-term viability of their product also. Within the RV crowd, the Victron name is held with high regard, and considered an extremely responsive and reliable brand with items that “just work”.

This charger is working great . I have charged a number of batteries with it and all went good. The charger does get quite warm when charging at 30 amp. I have a small fan running to keep it cool. At 15 amp it runs cool.

These work good, both running on a generator or plugged in. The amount of stuff that can be adjusted in settings is amazing. Way more than just 15A/30A. Can set the max voltage lower to be nicer to the batteries. Comes with pre-sets for LiFePO4 but I changed a little to my needs.These do seem to run hot when running full output so mount them vertical and make sure they have airflow. I dont like the philips heads in the screw terminals (I dislike philips heads in general). I put ferrules on the ends of my 6AWG cables so they attach to the screw terminals nice and clean.I originally bought one, liked it and bought another, liked how it worked in the field, and bought a 3rd. Maybe not the most cost effective way. These link up and sync good through bluetooth. I typically run on a generator to charge a LiFePO4 battery and then run other stuff off an inverter. Like a window AC and a small fridge. I turn the generator on in late morning with the battery a little bit discharged. 90 A directly into my battery is more than I want so I may put the 3rd charger on an "on-delay" relay to make it wait a few minutes until the AC load is steady.I have not tried the power supply function.

***review update November 4, 2022***Have used for over 95 charge cycles. Still an excellent LiFePO4 charger, but better using custom preset for expert users. Victron released a firmware update for hardware Rev. 2 units that allow much more adjustability, especially with regards to the maximum current. Prior to the new firmware, this unit worked at only 30 OR 15 amps, now I can specify any max current between 7.5 and 30.0 amps. This has allowed me to use it for many more applications. Also many more adjustable settings under advanced expert that allow detailed customization. Please download the VictronConnect app, and use the demo modes to fully explore the available settings prior to purchase, it can really give you lots of useful information. I lucked out, and after the update, have used it for smaller AGM batteries, and can charge my 24AH LiFePO4 DIY Jackery battery. I can charge my 100AH house battery from my Prius using a pure sine inverter (Samlex) in under 4 hours. PriusCampervan backup to solar panels when it’s raining too much, and although inefficient by converting DC to AC back to DC to charge a battery, I feel it allows much more control of the load on the Prius Hybrid system, since I can specify the max charging current, than a simple DC to DC charger (almost no adjustability). Very useful and has been working great for over a year and a half.***original review March 12, 2021***Tested for proof of concept charging a 100ah LIFEPO4 house battery in a unique application. Was able to charge 37Ah in one hour. Completed cycle charged 39.6Ah in 3 hours 6 minutes with BMS top balancing. Nice Bluetooth app, although you don’t use the iPhone to pair it to Bluetooth, just use the app and it finds the charger (works different that any Bluetooth I’ve ever used). Will update review once I start to really use and rely on it. I like that I can reduce it to half power to reduce th AC load if desired. It can also be used as a power supply.
