Victron Energy Blue Smart IP22 Smart Car Battery Charger 12V 30A, Trickle Charger for Car Battery and Desulfator for Motorcycle, ATV, RV, Lithium and Deep Cycle Batteries, UK, 3 outputs

Fantastic bit of kit, keeps three leisure batters topped up.

Great boat/marine product

I changed the factory installed charger in my boat to this . It was easy to install and works perfectly. The app is superb

Superb product, fitted it easily without any issues.

Unfortunately, mine was faulty on arrival - it charged the batteries, and bluetooth to the app showed it was working, but none of LED's lit up at all and the charger rattled if shaken, implying a loose component inside. So, sadly I've returned it for a refund.
