On my boat, isolating the engine battery from the house bank matters. This unit charges my house battery from the alternator while keeping the systems fully separated. Bluetooth monitoring is a nice touch. Marine-grade quality throughout.
18A is plenty for my small setup and the charger runs much cooler than I expected for an isolated unit. App works well. Would love a slightly longer set of mounting ears.
Clean install, perfect charging, zero issues.
My husband and I rewired our 30-foot sloop over the winter and chose this to keep the starter battery completely isolated from the lithium house bank. The isolation means no more worrying about stray currents eating our thru-hulls. It's been running every sailing weekend since spring without a hiccup. Checking the charge status from the cockpit via Bluetooth is genuinely delightful. Worth the price even before the discount.
Does its job well and the isolation is reassuring. It gets noticeably warmer than the non-isolated version my friend has, though still within spec. Just plan your mounting location accordingly.
I was skeptical of the isolation claim being worth the extra cost, but in a boat it absolutely is. Charging profile for lithium was preset and adjustable through the app in minutes. My batteries have never been healthier.
18A won't fast-charge a huge bank, but for my 100Ah setup it's plenty during a day of driving. The Bluetooth diagnostics helped me spot a bad crimp during installation, which was unexpected and appreciated.
Installed in my fishing boat eighteen months ago. Charges through rain, spray, and sweltering heat without complaint. I wouldn't trust anything else in a saltwater environment.
The charger itself charges fine, but the Bluetooth app keeps disconnecting on Android, which makes configuration frustrating. eventually got my settings in and it holds them, but the connectivity experience was annoying.
Isolated model because I didn't want any chance of my house loads affecting the starter battery. Clean output, quiet operation, and the app shows exactly what's happening at all times. Shipping was fast and the coupon stacked nicely.
Heavy unit, well potted, proper terminals. Charged my batteries flawlessly on a 1,500-mile road trip. Victron has earned my loyalty.
Three months of daily use in my delivery van. The dual-battery system works seamlessly and I check stats over Bluetooth every morning with my coffee. Only minor gripe is the mounting position needs clearance for the connector side.
