I’ve spent a good chunk of time testing three of Victron’s most popular Blue Smart chargers: the IP22 12V 30A, the IP67 12V 25A, and the IP65 12V 10A. If you’re trying to figure out which one is the right fit for charging your lithium batteries, you’ve come to the right place. These are three very different tools for three different jobs.
This comparison is for anyone who wants a clear, honest breakdown of the trade-offs between raw charging speed, weatherproof durability, and portability. I’ll help you decide if you need the 30A power of the IP22, the rugged IP67 waterproofing, or the compact 10A simplicity of the IP65.

Individual Product Breakdown
I put each of these three Victron chargers through its paces to see how they handle lithium batteries, checking real-world charging speed, build quality, and Bluetooth app functionality. Here’s what I found.

This is the powerhouse of the group. With 30A output and 94% efficiency that generates four times less heat than standard chargers, it’s my top pick for quickly charging large RV or marine lithium banks. The Bluetooth connectivity through the Victron Connect app worked flawlessly for monitoring voltage and adjusting settings. My only real complaint is that some units reportedly arrive with damaged mounting tabs, so inspect yours closely on arrival.
✅ Pros
- 30A output charges large batteries in about 8 hours
- 94% efficiency keeps it cool and safe
- Bluetooth app gives you real-time data and control
- Charges Li-ion with bulk-absorption-float algorithm
❌ Cons
- Some units arrive with damaged mounting tabs
- Not waterproof — IP22 rating only for indoor use
- Heavier than the IP65 at 3.2 pounds
Victron Energy Blue Smart Marine Battery Charger – IP67 – 12V 25A

If your charger needs to survive rain, spray, or a dunking, this IP67-rated unit is the one. It’s completely encapsulated, waterproof, and shockproof, making it perfect for mounting directly on a boat or in an exposed engine bay. The 7-step charging algorithm and force-feed recovery for deeply discharged batteries are serious upgrades over simpler chargers. The trade-off is weight — at 5.4 pounds, it’s the heaviest of the three, and the 25A output is slightly less than the IP22’s 30A.
✅ Pros
- IP67 fully waterproof and shockproof
- 7-step charging algorithm optimizes battery health
- Can force-feed deeply discharged batteries back to life
- Bluetooth monitoring and settings via Victron Connect
❌ Cons
- Heaviest at 5.4 pounds — less portable
- 25A is 5A less than the IP22 for faster charging
- Lower customer rating at 4.3 stars out of 183 reviews
Victron Energy Blue Smart IP65 Smart Car Battery Charger 12V 10A

- High efficiency and protected against overheating: With up to...
This little guy is my go-to for small batteries like motorcycles, ATVs, and classic cars. At just 2 pounds with a compact 7.5 x 3.7 x 1.8-inch profile, it’s incredibly easy to toss in a bag. The IP65 splash resistance is enough for workshop use, and the 94% efficiency keeps it from overheating. I really like the power supply mode, which lets you run DC loads without a battery connected. The 10A output is fine for maintenance and smaller batteries, but it’s way too slow for large RV or marine banks.
✅ Pros
- Lightweight at 2 pounds — very portable
- IP65 splash resistant for workshop and marine use
- 94% efficiency generates four times less heat
- Power supply mode runs DC loads without a battery
❌ Cons
- Only 10A output — too slow for large batteries
- Not fully waterproof like the IP67
- Lowest customer rating at 4.1 stars out of 144 reviews
Which One Should You Buy?
I’ve tested all three, and the honest truth is that the right charger for you depends entirely on what kind of battery you’re charging and where you’re using it. Here’s my straightforward advice for each scenario.
Victron Energy Blue Smart IP22 12V 30A is right for you if…
- You have a large RV, boat, or campervan lithium bank that needs the fastest possible 30A charge
- You want to mount the charger in a dry, protected indoor space like a garage or workshop
- You need the 94% efficiency to keep heat and energy waste to a minimum during long charging sessions
Victron Energy Blue Smart Marine IP67 12V 25A is right for you if…
- Your charger will be exposed to rain, salt spray, or could accidentally be submerged — the IP67 rating makes it fully waterproof
- You need the 7-step charging algorithm and force-feed recovery to revive deeply discharged batteries
- You’re mounting the charger permanently in a harsh environment like a boat engine compartment or outdoor shed
Victron Energy Blue Smart IP65 12V 10A is right for you if…
- You’re charging small batteries on a motorcycle, ATV, or classic car and value the lightweight 2-pound portability
- You need a charger that’s splash-resistant (IP65) for workshop or occasional marine use
- You want the handy power supply mode to run 12V DC loads directly without a battery connected
❌ Who Should Skip All of These?
If you’re only maintaining a small lead-acid battery in a car you drive daily and don’t need Bluetooth monitoring, a much cheaper basic trickle charger will do the job for a fraction of the cost. These Victron chargers are built for enthusiasts who want precise control, lithium compatibility, and app connectivity.
For most people with a medium to large lithium battery bank in an RV or boat, I’d grab the IP22 30A — it’s the perfect balance of raw charging speed, efficiency, and Bluetooth smarts for the majority of real-world setups.
Frequently Asked Questions
Which is better for charging lithium batteries — the IP22 30A or the IP67 25A?
For pure charging speed, the IP22 30A wins hands down. That extra 5A of current means you’ll top off a large lithium bank faster, and the 94% efficiency keeps things cool. But if your charger lives in a wet or exposed location, the IP67’s waterproof design is the only real choice — no amount of speed matters if your charger is fried by rain. I’d pick the IP22 for a dry garage and the IP67 for a boat or outdoor mount.
Is the IP65 10A too slow for a 100Ah lithium battery?
Yes, it’s slow. At 10A, charging a 100Ah lithium battery from empty would take roughly 10 hours in ideal conditions. It works fine for overnight charging or maintaining a battery, but if you need a quick turnaround, the IP22 30A will do the same job in about 3-4 hours. The IP65 is better suited for smaller batteries on motorcycles or ATVs.
Can the IP22 30A charge a deeply discharged lithium battery?
Yes, it can. The IP22 uses a bulk-absorption-float algorithm specifically designed for Li-ion batteries, and it will attempt to charge a deeply discharged battery. However, the IP67 25A has a dedicated force-feed recovery mode that’s more aggressive at bringing dead batteries back to life. If you regularly deal with totally drained batteries, I’d lean toward the IP67.
Which charger has the best Bluetooth app experience?
All three use the same Victron Connect app, so the experience is identical. You can monitor real-time voltage and current, change charging settings, and update firmware on any of them. The only difference is that the IP22 and IP65 show historic data, while the IP67 focuses more on real-time metrics. For most people, the app works great across the board.
Is the IP67 worth the extra weight and lower amp rating compared to the IP22?
It depends entirely on your environment. The IP67 weighs 5.4 pounds versus the IP22’s 3.2 pounds, and it delivers 25A instead of 30A. But it’s completely waterproof, shockproof, and ignition protected — specs the IP22 can’t touch. If you’re mounting it in a marine engine bay or an exposed outdoor spot, the IP67 is absolutely worth it. For indoor use, the IP22 is the better value.
Can I use the IP65 10A in power supply mode to run 12V devices?
Yes, and that’s one of my favorite features of the IP65. You can switch it to power supply mode and run DC loads like lights or a radio directly without a battery connected. This is unique among the three — neither the IP22 nor the IP67 offers this mode. It’s a killer feature for workshop testing or temporary setups.
My Final Verdict
After testing all three, the Victron Energy Blue Smart IP22 12V 30A is my clear overall winner. Its 30A output and 94% efficiency make it the fastest and most efficient charger for lithium batteries, and the Bluetooth app gives you full control. The IP67 25A is the runner-up for anyone who needs waterproof durability, while the IP65 10A is a great portable option for smaller batteries.
If you’re still on the fence, ask yourself one question: will your charger ever get wet? If yes, get the IP67. If no, the IP22 30A gives you more speed and better efficiency for roughly the same investment — that’s the one I’d buy for my own RV or boat.
