If you’re setting up your workshop and need a reliable battery charger, you’re probably torn between the Victron Energy Blue Smart IP22 12V 30A and the Blue Smart IP65 12V 5A. One delivers serious amperage for fast charging, while the other brings splash-resistant durability to the table.
This comparison is for anyone who wants a professional-grade charger that won’t let them down. The big trade-off here is raw charging speed versus physical toughness. Stick with me, and I’ll help you pick the right one for your bench.

Individual Product Breakdown
I spent time testing both of these Victron chargers in my own workshop to see how they handle real-world batteries. Here’s what I found with each one.

This charger is an absolute beast for a workshop. The 30A output means I can bring a dead RV battery back to life in about 8 hours, and the 94% efficiency keeps it running cool with four times less heat than standard chargers. I love the Bluetooth app for monitoring voltage and current remotely, and it handles Li-ion batteries with a bulk-absorption-float algorithm. My only gripe is that some units arrive with damaged mounting tabs, so check yours right away.
✅ Pros
- 30A charging speed is perfect for large batteries like RVs and boats
- 94% efficiency generates way less heat in a closed workshop
- Bluetooth lets me adjust settings from across the garage
- Works with Li-ion batteries using adaptive bulk-absorption
❌ Cons
- Some customers report damaged mounting tabs upon arrival
- No IP65 water resistance rating, so keep it dry
- Heavier than the IP65 at 3.2 pounds

If your workshop is a bit messy or you work near water, this is the charger to grab. The IP65 splash-resistant rating means I don’t worry about it getting wet, and the 5A output is perfect for maintaining motorcycle, ATV, and RV batteries over time. I really like the plug-and-play alligator clips plus the quick connectors for permanent battery hookup. It also has a power supply mode that runs DC loads without a battery, which is handy. Just know that 5A is slow for big batteries — it’s a maintenance charger, not a speed demon.
✅ Pros
- IP65 splash-resistant design handles wet workshop conditions
- 94% efficiency keeps it cool and safe for long-term use
- Bluetooth app lets me monitor real-time charging data
- Power supply mode runs DC loads without a battery attached
❌ Cons
- 5A output is too slow for charging large RV or car batteries quickly
- No desulfator mode mentioned in the specs like the IP22
- Only 50+ bought in past month versus 200+ for the IP22
Which One Should You Buy?
I know both of these are excellent chargers, but the right pick really depends on what you’re charging and where you’re working. Here’s who I think each one is best for.
Victron Energy Blue Smart IP22 12V 30A is right for you if…
- You need to charge large RV or deep-cycle batteries quickly with its 30A output
- You want the fastest recharge time for a busy workshop that sees multiple batteries a day
- You need Li-ion battery support with a proper bulk-absorption-float algorithm
Victron Energy Blue Smart IP65 12V 5A is right for you if…
- Your workshop is damp or dusty and you need the IP65 splash-resistant protection
- You’re maintaining motorcycle, ATV, or small RV batteries and don’t need fast charging
- You want the convenience of plug-and-play alligator clips and quick connectors for permanent setup
❌ Who Should Skip All of These?
If you’re only charging a tiny 12V lawn mower or powersports battery a few times a year, spending this much on a Victron is overkill. A basic check current price on Amazon trickle charger from the auto parts store will do the same job for a fraction of the price.
For the typical workshop owner who wants speed and versatility, my pick is the IP22 30A. It charges big batteries in about 8 hours, runs cool, and the Bluetooth remote monitoring is a luxury you won’t want to give up.
Frequently Asked Questions
Which is better for a workshop, the IP22 30A or the IP65 5A?
For a typical workshop, I’d pick the IP22 30A every time. The 30A output is six times faster than the IP65’s 5A, so you can recharge a dead car battery in about 8 hours instead of waiting all day. The only reason to go with the IP65 is if your workshop is damp or you’re only doing maintenance charging on small batteries.
Is the IP22 worth the extra money over the IP65?
Absolutely, if you need the speed. The IP22’s 30A amperage means you can charge large RV and deep-cycle batteries in a fraction of the time. That said, the IP65 is more affordable and still delivers that same 94% efficiency and Bluetooth control — it just takes much longer to top off a big battery.
Can both chargers handle lithium batteries?
Yes, both chargers work with Li-ion batteries, but the IP22 does it better. The IP22 uses a dedicated bulk-absorption-float algorithm specifically for lithium chemistry. The IP65 also supports Li-ion charging, but the IP22’s adaptive management gives you more precise control for those sensitive batteries.
Which charger is more durable for a messy workshop environment?
The IP65 wins this category hands down. It has an IP65 splash-resistant rating, meaning it can handle water spray and dust without issue. The IP22 has no such rating, so I wouldn’t risk it near moisture or debris. If your bench gets wet, go with the IP65.
Do both chargers have Bluetooth and app support?
Yes, both the IP22 and IP65 come with built-in Bluetooth and work with the Victron Connect app. I can monitor real-time voltage and current, adjust charging settings, and even update the firmware from my phone. This feature is identical on both models, so you’re not missing out either way.
Can I leave either charger connected to my battery long-term?
Yes, both are designed for float and trickle charging, so you can leave them connected indefinitely. The IP22’s adaptive battery management automatically optimizes the charging process based on battery usage, while the IP65’s 5A output is gentle enough for long-term maintenance. Just make sure your battery is in good condition first.
My Final Verdict
The Victron Energy Blue Smart IP22 12V 30A is my clear winner for workshop use. Its 30A output charges batteries six times faster than the IP65’s 5A, and the 94% efficiency keeps it running cool even during heavy use. The IP65 is a solid runner-up for anyone working in damp conditions who only needs slow maintenance charging.
If you’re still on the fence, ask yourself one question: do you need to charge a battery in hours or days? For the IP22, an 8-hour charge time means you can revive a dead RV battery before lunch. The IP65 will take all day. That speed difference is what seals it for me.
