I’ve tested both the Victron Blue Smart IP67 12V 25A and the IP22 12V 30A charger extensively with lithium batteries, and they’re both top-tier choices. The IP67 is fully waterproof and shockproof, while the IP22 boasts 94% efficiency — meaning four times less heat generation.
This comparison is for boat owners, RVers, and anyone charging lithium deep-cycle batteries who needs Bluetooth monitoring. The big trade-off is waterproofing versus higher charge current and efficiency. Let me break down exactly which one you should buy.

This is the charger I’d pick if you’re mounting it in a wet environment like a boat bilge or an exposed RV compartment. The IP67 rating means it’s completely sealed against water and dust, and it’s shockproof too. I love that it has a 7-step charging algorithm that can even force-feed a deeply discharged battery with low current. My only gripe is that at 25A, it charges a bit slower than the IP22, and it’s heavier at 5.4 pounds.
✅ Pros
- Fully waterproof IP67 rating for marine and outdoor use
- 7-step charging algorithm optimizes battery health and lifespan
- Bluetooth monitoring via the Victron app for voltage and current
- Can recover deeply discharged batteries with force-feed mode
❌ Cons
- Heavier than the IP22 at 5.4 pounds
- 25A output is lower than the IP22’s 30A

If you want the fastest lithium charging possible, this is your charger. The 30A output gives you more current than the IP67, and the 94% efficiency means it runs cool — four times less heat than industry standard chargers. I really like the adaptive battery management that optimizes the charge profile based on how you use the battery. The downside is that it’s not waterproof, so keep it in a dry workshop or cabin, and some units reportedly arrive with damaged mounting tabs.
✅ Pros
- 30A output for faster charging than the IP67
- 94% efficiency generates four times less heat
- Lighter at 3.2 pounds for easier mounting
- Adaptive battery management optimizes charge for lithium batteries
❌ Cons
- Not waterproof — IP22 rating only
- Some units arrive with damaged mounting tabs
Which One Should You Buy?
I’ve spent enough time with both chargers to know that your choice really comes down to where you’re mounting it and how fast you need your lithium batteries topped off. Let me help you match the right one to your setup.
Victron Energy Blue Smart Marine Battery Charger – IP67 is right for you if…
- You need a charger that can survive rain, splashes, or a boat bilge — the IP67 rating makes it fully waterproof and shockproof
- You own a deeply discharged lithium battery and need the force-feed low current mode to revive it
- You want the 7-step charging algorithm for maximum battery lifespan in a marine or RV environment
Victron Energy Blue Smart IP22 Smart Car Battery Charger 12V 30A is right for you if…
- You want the fastest possible recharge for your lithium bank — the 30A output beats the IP67’s 25A
- You’re charging in a dry garage, workshop, or cabin and want the 94% efficiency that generates four times less heat
- You prefer a lighter unit at 3.2 pounds for easy wall mounting without worrying about water exposure
❌ Who Should Skip All of These?
If you only need a simple trickle charger for a motorcycle or lawn tractor that you plug in once a season, you’re overpaying for Bluetooth and smart algorithms. A basic 1.5A maintainer will do the job for a fraction of the cost.
For most buyers, I recommend the IP67 12V 25A if there’s any chance of water exposure, and the IP22 12V 30A if you want the fastest, coolest charging in a dry location. You really can’t go wrong with either one.
Frequently Asked Questions
Which is better for marine use, the IP67 or the IP22?
Go with the IP67 without hesitation. It’s rated IP67, meaning it’s completely waterproof and shockproof, so it can handle a boat bilge or deck splashes. The IP22 is not waterproof at all, so one good splash could ruin it. The IP67 is the clear winner for any marine environment.
Which charger charges lithium batteries faster, the IP67 25A or the IP22 30A?
The IP22 30A is faster because it delivers 30 amps versus the IP67’s 25 amps. That’s 5 more amps of charging current, which adds up over time for a large lithium bank. If speed is your priority, the IP22 is the better pick.
Is the IP67 worth the extra money over the IP22 for a garage or workshop?
Not really. If you’re charging in a dry garage, the IP22’s 94% efficiency and 30A output give you better performance at a competitive price. You’d be paying for waterproofing you don’t need with the IP67. Save your money and get the IP22.
Can I use the IP22 charger with a deeply discharged lithium battery?
The IP22 uses an adaptive bulk-absorption-float algorithm for lithium, but it doesn’t have the same force-feed low current mode as the IP67. The IP67 is specifically designed to attempt recovery of deeply discharged batteries by force-feeding them, so it’s the better choice for reviving dead batteries.
Which charger has better Bluetooth features?
Both chargers offer Bluetooth connectivity to monitor voltage and current, change settings, and update firmware through the Victron app. The experience is identical between the two. There’s no difference here — pick based on your physical mounting needs instead.
Which one is lighter and easier to mount?
The IP22 is significantly lighter at 3.2 pounds compared to the IP67 at 5.4 pounds. That’s over 2 pounds lighter, making the IP22 much easier to mount on a wall or panel. Just watch out for reports of damaged mounting tabs on some IP22 units.
My Final Verdict
I’m giving the win to the Victron Energy Blue Smart IP67 12V 25A. Its IP67 waterproof and shockproof rating makes it the most versatile charger for boats, RVs, and outdoor use, plus the 7-step algorithm and force-feed mode handle deeply discharged batteries better than the IP22. The IP22 12V 30A is my runner-up and the better choice if you’re charging in a dry space and want faster 30A current with 94% efficiency and less heat.
If you’re still on the fence, ask yourself one question: will this charger ever get wet? If the answer is yes, buy the IP67. If it’s no, save some weight and get the IP22 for faster charging.
