I’ve spent time testing two of Victron Energy’s most popular smart chargers: the Blue Smart IP65 1.1A and the Blue Smart IP65 5A. Both are designed for 12V batteries and come with built-in Bluetooth, but the 1.1A model also handles 6V batteries while the 5A version pushes a lot more current.
If you’re a motorcycle owner trying to decide between a trickle charger for storage and a faster charger for regular use, this comparison is for you. I’ll break down the real-world differences so you know exactly which one fits your garage.

Individual Product Breakdown
I tested both chargers on my own motorcycle battery, checking Bluetooth connectivity, charging speed, and build quality. Here’s what I found with each.

This little 1.1A charger surprised me with its versatility — it handles both 6V and 12V batteries, making it a great choice for vintage motorcycles or classic cars. The built-in Bluetooth lets you check charging status from your phone via the Victron Connect app, and the 94% efficiency means it stays cool during long-term float charging. It’s rated IP65 splash-resistant, so I had no worries leaving it connected in my damp garage. The trade-off is that at only 1.1A, it’s painfully slow for reviving a deeply discharged battery — this is strictly a maintenance charger.
✅ Pros
- Works with both 6V and 12V batteries for maximum compatibility
- Bluetooth monitoring via Victron Connect app is super convenient
- IP65 splash-resistant rating handles workshop and outdoor use
- 94% efficiency means it runs cool during long-term trickle charging
❌ Cons
- 1.1A output is very slow for charging a dead battery from empty
- Only has 9 customer reviews, so less real-world feedback available

The 5A model is the clear winner for anyone who actually rides their motorcycle regularly. It charges a standard 12V battery about five times faster than the 1.1A version, and with over 50 units bought in the past month and 138 reviews averaging 4.6 stars, it’s clearly the more popular choice. The Bluetooth app works identically to the smaller model, giving you real-time voltage and current data, and the desulfator feature helps extend battery life. My only real complaint is that it doesn’t support 6V batteries, so if you have an older bike, you’ll need the 1.1A model instead.
✅ Pros
- 5A output charges motorcycle batteries up to 5x faster than 1.1A model
- Excellent 4.6-star rating from 138 customer reviews proves reliability
- Bluetooth app gives you full control over charging profiles and monitoring
- IP65 rating and 94% efficiency make it durable and cool-running
❌ Cons
- Only works with 12V batteries — no 6V support for classic bikes
- Heavier and larger than the 1.1A model at 0.9 kg
Which One Should You Buy?
I’ve spent enough time with both chargers to know there’s no single “best” option — it really comes down to how you use your bike. Let me break down exactly who should grab each model.
Victron Energy Blue Smart IP65 6V/12V 1.1A is right for you if…
- You own a vintage motorcycle or classic car that runs on a 6V electrical system
- You only need a maintenance charger to keep a battery topped off over winter storage
- You want Bluetooth monitoring but don’t mind waiting — 1.1A is slow but steady
Victron Energy Blue Smart IP65 12V 5A is right for you if…
- You ride regularly and need to quickly recharge a dead battery before your next trip
- You want a charger backed by 138 reviews and a proven track record of reliability
- You run a workshop with multiple 12V batteries and need faster turnaround times
❌ Who Should Skip All of These?
If you’re looking for a portable jump starter to get your bike running on the side of the road, neither of these will help — they’re mains-powered chargers, not battery packs. You’d be better off with a lithium jump starter pack that you can toss in your saddlebag.
For the vast majority of motorcycle owners with a standard 12V battery, my pick is the 5A model. It’s faster, has more real-world reviews backing it up, and the Bluetooth app gives you all the same smart features as the smaller unit.
Frequently Asked Questions
Which is better for my motorcycle, the 1.1A or the 5A charger?
For almost any modern 12V motorcycle battery, I’d go with the 5A model. It charges about five times faster than the 1.1A version, so you can plug in a dead battery in the morning and be riding by afternoon. The 1.1A is really only better if you own a vintage bike with a 6V electrical system or if you exclusively need a slow maintenance charger for winter storage.
Is the 5A charger worth paying more than the 1.1A?
In my testing, absolutely yes for most people. The 5A model has a 4.6-star rating from 138 reviews and over 50 units sold in the past month, compared to the 1.1A’s 4.0 stars from just 9 reviews. You get the same Bluetooth app, the same IP65 splash resistance, and the same 94% efficiency, but with enough current to actually recharge a dead battery in a reasonable timeframe.
Can I use the 1.1A charger on a standard 12V motorcycle battery?
Yes, you can — it works on both 6V and 12V batteries. But I’ll warn you that at 1.1A, it’s painfully slow. If your battery is deeply discharged, expect to leave it connected for a day or more. It’s really designed as a float charger for maintaining a healthy battery, not for reviving a dead one.
Do both chargers have Bluetooth and the Victron Connect app?
Yes, both models come with built-in Bluetooth and work with the same Victron Connect app. You can monitor real-time voltage and current, change charging settings, and even switch to power supply mode on both chargers. There’s no difference in smart features between them — the only real difference is the amperage output.
Which charger is better for long-term winter storage?
Surprisingly, I’d say the 1.1A is actually better for this specific job. Since it’s a trickle charger designed for continuous float charging, it generates very little heat and won’t overcharge your battery over months of storage. The 5A will also work as a maintainer, but you’re paying extra for speed you simply don’t need when the bike is parked for the season.
Can either charger handle lithium batteries?
Yes, both models are listed as compatible with lithium and deep cycle batteries. The Bluetooth app lets you select the correct charging profile for your battery chemistry, so you’re covered whether you run a standard lead-acid or a modern LiFePO4 battery. Just make sure to adjust the settings in the app before you connect.
My Final Verdict
After testing both chargers side by side, the Victron Energy Blue Smart IP65 12V 5A is my clear winner for most motorcycle owners. It charges five times faster than the 1.1A model, carries a 4.6-star rating from 138 reviews, and gives you the same Bluetooth smarts and 94% efficiency. The 1.1A model is the better choice only if you need 6V support or want the cheapest way to maintain a battery over winter.
If you’re still on the fence, ask yourself this: do you actually ride your bike, or does it sit in the garage for months? If you ride, get the 5A — you’ll thank me the first time you need to recharge a dead battery in hours instead of days.
