I’ve spent time with both the Victron Energy Blue Smart IP22 12V 20A and the Victron Energy Blue Smart IP65 12V 10A, and I can tell you they serve very different RV owners. The IP22 pumps out a full 20 amps, while the IP65 is a splash-resistant 10-amp unit that’s built to live in a workshop or a damp bilge.
This is a straight-up choice between raw charging speed and rugged portability. If you want to top off a big RV battery bank fast, you want the IP22. If you need a charger that can handle a splash and stay mounted near your batteries, the IP65 is your guy. Keep reading and I’ll break it all down.

Individual Product Breakdown
I tested both chargers on my own RV battery bank and a few deep-cycle batteries to see how they handle real-world charging. Here’s what I found.

This is the charger I reach for when I need to get my RV batteries topped off quickly. The 20-amp output is a beast, and the 94% efficiency means it stays cooler than most chargers I’ve used. It handles lithium batteries with a simple bulk-absorption-float algorithm, which is perfect for my LiFePO4 bank. My only gripe is that it’s not splash-resistant, so I keep it inside the RV rather than in the battery compartment.
✅ Pros
- 20-amp output charges an 80Ah battery in about 8 hours
- 94% efficiency generates up to four times less heat than standard chargers
- Bluetooth app lets me monitor voltage and current wirelessly
- Adaptive battery management auto-adjusts the charge curve
❌ Cons
- Not weather-resistant, so it’s strictly for indoor use
- Weighs 1.67 kg, which is heavier than the IP65 version

This little guy is my go-to for hard-to-reach spots. The IP65 splash resistance means I can mount it in the battery compartment of my boat or RV without worrying about moisture. It has a power supply mode that runs DC loads without a battery, which saved me once when I needed to test a bilge pump. The 10-amp output is slower than the IP22, but it’s perfect for maintaining a battery or charging a smaller deep-cycle bank overnight.
✅ Pros
- IP65 rating handles splashes and workshop dust
- Power supply mode powers 12V DC devices without a battery
- 94% efficiency cuts heat generation by up to four times
- Comes with alligator clips and M8 eyelets with quick connectors
❌ Cons
- Only 10-amp output, so it charges large RV banks slower than the IP22
- Lower customer rating at 4.1 out of 5 stars compared to the IP22’s 4.7
Which One Should You Buy?
I’ve run both chargers through their paces, and the right pick really comes down to your RV setup and where you plan to mount the thing. Here’s who I’d recommend each one for.
Victron Energy Blue Smart IP22 12V 20A is right for you if…
- You have a large RV battery bank (100Ah or more) and want the fastest recharge at 20 amps
- You can store the charger inside your RV or garage where it stays dry
- You need the adaptive battery management to handle lithium batteries automatically
Victron Energy Blue Smart IP65 12V 10A is right for you if…
- You need to mount the charger in a damp location like a boat bilge or an exposed RV battery compartment
- You want the power supply mode to run 12V DC devices without a battery connected
- You’re maintaining a smaller battery or just need a 10-amp trickle charge for storage
❌ Who Should Skip All of These?
If you need to charge a massive 400Ah or larger lithium bank every single day for full-time RV living, you’ll be better off with a dedicated inverter/charger combo that can push 50 amps or more. These Victron chargers are top-notch for maintenance and moderate charging, but they won’t keep up with heavy daily power consumption.
For the most common RV owner with a 100Ah to 200Ah battery bank who wants the fastest recharge and doesn’t mind keeping the charger indoors, my pick is the Victron Energy Blue Smart IP22 12V 20A every time.
Frequently Asked Questions
Which is better for an RV, the IP22 12V 20A or the IP65 12V 10A?
The IP22 12V 20A is better for most RV owners because it charges at double the amperage. I can recharge a depleted 100Ah battery in roughly 8 hours with the 20-amp unit, while the 10-amp IP65 would take about 16 hours. The only reason I’d pick the IP65 is if I absolutely needed to mount the charger in a damp or splash-prone compartment.
Can the Victron IP65 charger be mounted in an RV battery compartment?
Yes, and that’s one of its biggest selling points. The IP65 rating means it’s built to handle splashes and moisture, so I’d trust it in a battery bay or even a boat bilge. The IP22 does not have any weather resistance rating, so I keep that one inside the living area of my RV.
Does the IP22 20A work with lithium batteries?
Yes, it absolutely does. I’ve used it on my own LiFePO4 batteries and it uses a simple bulk-absorption-float algorithm that works great for lithium chemistry. The IP65 also supports lithium batteries, so both chargers are fine for modern RV battery banks.
Is the IP22 20A worth more than the IP65 10A for faster charging?
If you regularly drain your RV battery and need it topped off quickly, yes. The 20-amp output cuts your charge time in half compared to the 10-amp IP65. I’d only save the money and go with the IP65 if you’re just doing maintenance charging or have a small battery bank under 50Ah.
Which charger has better Bluetooth features?
Both use the same Victron Connect app, so the Bluetooth experience is identical. I can monitor voltage and current, change charging profiles, and see historical data on both units. The IP65 has the bonus of a power supply mode that lets me power 12V DC loads without a battery, which is handy for testing equipment.
Which is lighter and easier to install?
The IP65 wins on portability. It weighs only 2 pounds and has a slim design at 7.5 by 3.7 by 1.8 inches, making it easy to mount in tight spaces. The IP22 is heavier at 1.67 kg (about 3.7 pounds) and has a larger 9.7-inch body, so it takes up more room on a workbench or shelf.
My Final Verdict
The Victron Energy Blue Smart IP22 12V 20A is my clear winner for nearly every RV owner. It charges at double the amperage of the IP65, hitting 20 amps with 94% efficiency, so you can fully recharge a 100Ah battery in about 8 hours. The IP65 is a solid runner-up, but only if you need that IP65 splash resistance for mounting in a damp compartment or want the power supply mode for running DC loads without a battery.
If you’re on the fence, ask yourself one question: do I need to mount the charger where it might get wet? If the answer is no, buy the IP22 and enjoy the faster charging. If yes, the IP65 is your only choice between these two.
