If you’re trying to keep your ATV’s battery healthy, you’re probably stuck between three excellent Victron Energy options: the Blue Smart IP22 12V 20A, the Blue Smart IP22 24V 16A, and the Blue Smart IP65 24V 8A. The big question is whether you need the raw speed of a 20-amp charger, the versatility of three outputs, or the rugged weather resistance of an IP65-rated unit.
I’ve spent time looking at the specs for all three, and this comparison is for any ATV owner who wants a reliable, Bluetooth-connected charger that won’t leave them stranded. The trade-off here is simple: more amps mean faster charging but less portability, while weather resistance and multi-battery charging add convenience. Let me break down exactly which one fits your garage or trailer.

This is the charger I’d grab for any standard 12V ATV battery. The 20-amp output is the fastest of the bunch, and with 94% efficiency it barely warms up compared to older chargers. It’s a single-output unit, so you’re only charging one battery at a time, but for most riders that’s all you need. The Bluetooth connectivity in the Victron Connect app makes checking voltage and current super easy without walking to the garage.
✅ Pros
- 20-amp output charges most 12V ATV batteries in about 8 hours
- 94% efficiency means four times less heat than industry standard
- Works with lithium, deep cycle, and standard lead-acid batteries
- Built-in desulfator extends battery life
❌ Cons
- Single output only — can’t charge multiple batteries at once
- Heavier at 1.67 kg compared to the IP65 model
- Not splash-resistant like the IP65 version

If you run a 24V ATV or have a fleet of machines, this is the charger I’d pick. It pumps out 16 amps at 24 volts, and the three outputs let you charge multiple batteries simultaneously — perfect for keeping a couple of ATVs and a spare battery ready to go. It’s lighter than the 12V 20A model at 1.3 kg, which makes it easier to move around the shop. Just keep in mind it’s not weather-resistant, so keep it indoors.
✅ Pros
- Three outputs let you charge three batteries at once
- 16-amp output is solid for 24V ATV batteries
- Lighter build at 1.3 kg makes it easy to carry
- Adaptive battery management optimizes charge for each battery type
❌ Cons
- Not splash-resistant — must stay in dry areas
- Only 16 amps, slower than the 20A 12V model
- No included alligator clips in the box
Victron Energy Blue Smart IP65 Smart Car Battery Charger 24V 8A
24V | 8 Amps | IP65 Splash-Resistant | 2 lbs

- Built-in Bluetooth: This battery charger is equipped with built-in...
- High efficiency and protected against overheating: With up to...
This is the charger I’d recommend for anyone who keeps their ATV in a damp garage, open trailer, or outdoors. The IP65 rating means it’s splash-resistant, and at only 2 pounds it’s the lightest of the three. It delivers 8 amps at 24 volts, which is slower than the IP22 24V model, but the trade-off is you can leave it connected in less-than-ideal conditions. The included alligator clips and M8 eyelets make it plug-and-play right out of the box.
✅ Pros
- IP65 splash-resistant design handles rain and moisture
- Ultra-light at just 2 pounds for easy portability
- Includes alligator clips and M8 eyelets with quick connectors
- Can switch to power supply mode to run DC loads without a battery
❌ Cons
- Only 8 amps — much slower than the 16A and 20A models
- Single output, can’t charge multiple batteries
- Slightly lower customer rating at 4.6 stars vs 4.7 for the IP22 models
Which One Should You Buy?
I’ve spent enough time with these specs to know there’s no single winner for everyone. Your decision really comes down to your ATV’s voltage, how fast you need to charge, and where you’ll be plugging it in.
Victron Energy Blue Smart IP22 12V 20A is right for you if…
- You own a standard 12V ATV and want the fastest charge possible with that 20-amp output
- You need a charger that works with lithium and deep cycle batteries, not just lead-acid
- You want a desulfator built in to revive and maintain older ATV batteries
Victron Energy Blue Smart IP22 24V 16A is right for you if…
- You run a 24V ATV and need to charge multiple batteries at once with those three outputs
- You manage a small fleet of ATVs and want one charger to handle several batteries in rotation
- You prefer a lighter unit at 1.3 kg for carrying between workbenches
Victron Energy Blue Smart IP65 24V 8A is right for you if…
- You keep your ATV in a damp garage or open trailer and need that IP65 splash resistance
- You want the lightest option at just 2 pounds for tossing in a saddlebag
- You need a power supply mode to run DC devices without a battery connected
❌ Who Should Skip All of These?
If you’re still running a 6V ATV battery or you need a charger that can handle both 12V and 24V systems without buying separate units, none of these will work for you. You’d be better off looking at a multi-voltage charger that covers both ranges.
For most ATV owners running a standard 12V battery, I’d grab the Victron Energy Blue Smart IP22 12V 20A — it’s the fastest, most efficient option and the Bluetooth app makes it a breeze to monitor your battery health from your phone.
Frequently Asked Questions
Which Victron charger is best for my 12V ATV battery?
If your ATV runs on a 12V system, the Victron Energy Blue Smart IP22 12V 20A is the clear choice. It’s the only one of these three that outputs 12 volts, and at 20 amps it will charge your battery in about 8 hours. The other two are both 24V chargers, so they simply won’t work with a standard 12V ATV battery without damaging it.
Is the IP65 24V 8A worth it over the IP22 24V 16A for outdoor use?
Yes, absolutely — if you’re charging in a damp environment. The IP65 model is splash-resistant, while the IP22 24V 16A has no weather protection at all. The trade-off is speed: the IP65 delivers only 8 amps versus the IP22’s 16 amps, so it’ll take roughly twice as long to charge the same 24V battery. For a garage or workshop, go with the IP22 16A. For a wet trailer or outdoor shed, the IP65 is worth it.
Can I charge lithium batteries with any of these Victron chargers?
Yes, all three chargers can handle lithium batteries. They use a simple bulk-absorption-float algorithm specifically designed for Li-ion chemistry. I’d just make sure you use the Bluetooth app to select the correct battery profile before plugging in, since lithium batteries need different voltage thresholds than lead-acid.
Which charger charges faster — the 12V 20A or the 24V 16A?
That depends on your battery voltage. For a 12V battery, the 12V 20A charger is faster because it’s pumping out 20 amps. For a 24V battery, the 24V 16A model is the faster option since the 12V 20A charger can’t even charge a 24V system. You can’t compare amp ratings directly across different voltages — always match the charger voltage to your battery first.
Does the three-output IP22 24V 16A charge each battery at full speed?
No, it splits the total 16 amps across all three outputs. If you connect three batteries, each one gets roughly 5.3 amps instead of the full 16. That’s still enough for a slow maintenance charge, but if you need to fast-charge a single 24V battery, you’re better off using just one output or picking the single-output IP65 24V 8A.
Which charger is the lightest and most portable for trailside use?
The Victron Energy Blue Smart IP65 24V 8A wins here by a long shot at just 2 pounds. The IP22 models weigh 1.67 kg and 1.3 kg respectively, which is about 3 to 3.7 pounds — noticeably heavier. Plus the IP65’s splash resistance means you can actually use it outside without worrying about rain. Just remember it’s only 8 amps, so it’ll be slower on the trail.
My Final Verdict
For the vast majority of ATV owners, the Victron Energy Blue Smart IP22 12V 20A is my clear winner. It delivers the fastest charge at 20 amps with 94% efficiency, works with both lithium and lead-acid batteries, and the Bluetooth app makes monitoring effortless. The runner-up, the IP22 24V 16A, is better if you run a 24V system and need to charge multiple batteries at once with its three outputs.
If you’re still on the fence, ask yourself one question: what voltage is your ATV battery? If it’s 12V, the IP22 12V 20A is the only option that will work, and it’s the best one anyway. If you need 24V and outdoor durability, the IP65 24V 8A is worth the slower charge for that splash resistance.
