Victron Energy Blue Smart IP65 24V 5A Battery Charger with Bluetooth, Float & Trickle Charging and Desulfation for RV, Marine, Motorcycle and Lithium Batteries

Checking charge status from my phone without walking to the shed is a small luxury I now can't live without. The desulfation mode revived a truck battery I'd written off as dead. IP65 housing means I can leave it mounted outdoors under my RV awning without worry. Excellent little charger.

Two of my 24V cart batteries were sluggish after a neglected winter. Ran the recovery mode and both bounce back like new now. The charge curve is smart about lithium and lead-acid alike. Half off made this an easy purchase and it exceeded expectations.

Build quality is typically excellent Victron and the app gives clear insight into every charge phase. Just remember 5A is maintenance territory, not fast charging — it takes a full day to bring my trolling battery bank back from half. For keeping batteries healthy between trips, it's ideal.

Mounted this on my boat trailer, plugged it into a timer outlet, and haven't thought about my batteries since. Bluetooth status checks confirm everything is healthy. Perfect.

No fault in the charging quality — batteries come back full and the float stage is gentle and smart. I just underestimated how long 5A takes on a large bank, so plan accordingly. The Bluetooth connection occasionally drops but reconnects on its own.

I manage batteries for my motorcycle, a garden tractor, and a portable power station, and this handles all of them with the right charge profiles selected in the app. The desulfation setting brought my old tractor battery back from the grave — genuinely shocked me. It's survived two rainy seasons mounted outside with zero corrosion or water intrusion. Efficiency is high enough that it barely registers on my electric bill. Worth the full price, and at half off it's a joke not to own one.

Six months on my sailboat maintaining the starter battery. The storage mode is exactly right for long periods at the dock, and I get alerts on my phone if anything looks off. The AC cable could be a bit longer, minor gripe. Dependable product.

Attempted the repair mode on a badly sulfated deep-cycle battery as a last resort before recycling it. Three days later it's holding charge better than it has in years. This charger paid for itself in one save.
