Orion XS Smart DC to DC Battery Charger 12/12 50A (700W) - IP65 Dust & Waterproof - Fully Configurable - Remote Management Possible - Advanced Battery Protection

Quality unit does the job it’s supposed to and very lightweight and surprisingly small

Fantastic kit batteries full all the time

Fitted to a narrow boat this now takes power from the alternator/starter battery only when the engine is running and the voltages are high enough (values can be set). It then helps charge a large lifepo4 battery at set amperage values ensuring the alternator doesn't over heat from constant charging and protection from a sudden end charging spike (lifepo4 will take a constant voltage/amperage until full then stop charging whereas lead acid voltages taper off as they become charged). It "talks" to the victron mppt and inverter via a Bluetooth network (inbuilt) and keeps the charging values inline with the battery requirements and solar feed. Gets luke warm instead of hot like the older units. Brilliant bit of kit as the engine bay is now an isolated unit from the leisure system.

I was surprised at how small this unit was compared to my Solar MPPT 100/50 unit (see photo). There are no heatsink fans on the back so I was worried that it would get hot, but it doesn’t. As usual, the VictronConnect app is where it’s at and it’s great to be able to see Solar and Alternator charging from the same place. Really excellent system. Previous to this I was just charging the leisure batteries (4 x 100Ah) from the alternator when solar wasn’t cutting it over winter, but it took forever to charge to 100% and never reached Absorption voltage. This however is a night and day difference in terms of charging in the way it controls the voltage and current when charging. True bulk, absorption, float and storage states means it charges the batteries quickly. Easily three times quicker than using the alternator alone - depending on state of charge. The entire Victron system is highly recommended. A+

Great improvement on the 30 amphr Version!

Great item and seller would recommend

I had a Sterling Power 60a charger which went faulty. Their customer service was useless so I decided to try out this Victron unit. It's a fraction of the cost, a fraction of the size, it runs silently & charges better than my old one. I have many Victron products & I can't fault any of them. Buy this with confidence. You will be happy

Great bit of kit, very controllable for different requirements

Llego en fecha prevista, producto de gran calidad.

Der DC-DC Laderegler von Victron wurde mir bereits mehrmals empfohlen und ist jetzt auch bei mir im Auto verbaut. Er lädt zuverlässig meine zweite Batterie und es ist toll auch per Bluetooth die Kontrolle zu haben. Die Verbindung ist schnell hergestellt und stabil. Bisher bin ich extrem zufrieden mit dem Gerät

Très bon produit , minuscule vis à vis de la gamme précédente et ne chauffe pas énormément malgré des charges à 40A.

Funziona benissimo

Early days yet I know, but installed it two days ago to replace a different brand that was nothing but trouble. This unit is easy to setup and just WORKS. Installed on a 2021 MB Sprinter motor home and it's well worth the extra dollars for a well designed and foolproof item. 5 stars.
