excellent service had to exchange product due to failure. The exchange worked quickly and unbureaucratically with the help of Victron (gives a 5-year guarantee).

Excellent Easy install. Works well. Worth pointing out in general the Bluetooth for this range of products isn't the strongest. E.g sometimes can't get it from sitting in the cockpit. But that's a minor detail because it's not a hassle to go near it the charger and engine detection work really well

Nothing to say a quality service with decent shipping costs as before the covid. 29.95 euros for Polynesia is good and invites you to come back to SVB.

Charging booster with very good efficiency, charging current continuously adjustable via app

The charging booster is currently being tested during our spring cruise.

So far, it's working perfectly!

I've replaced my lead-acid leisure batteries with three LiFePO4 batteries. The starter battery remains lead-acid.

My charging and power supply setup now consists of:

- 1 x Victron 15A mains charger for the lead-acid battery

- 1 x Victron 30A mains charger for the lithium batteries

- 1 x Victron 15A solar charge controller for the leisure batteries

- 1 x Victron 1212 50 charge booster

- 1 x Ective 300S battery box, 300Ah, approx. 3600W, primarily for mains-powered devices including TV, cool boxes, induction cooktops, Thermomix, contact grill, air fryer, etc.

I'm still working on fine-tuning the settings, because according to the Victron Connect A0, the leisure batteries are usually charged via the 15A charger, which is intended exclusively for the lead-acid starter battery, presumably indirectly. My new charging booster seems to think, even when connected to shore power, that my engine is running and that it should be charging both the starter and house batteries.

What would a skipper's life be without unsolved mysteries...?

An excellent DC/DC charger. I especially love the automatic motor start detection, which greatly simplifies use and allows you to forget about it. Simple and transparent to use, I love it!

Good marine DC-DC charger for LiFePo batteries

Does the job charging a 300Ah LiFePo battery bank from a lead acid starter battery 110A rated alternator. Easy installation and configuration over Bluetooth using Victron app.
Earlier models (ORI121217040) had reported problems with VHF noise.
I did not observe any such problems with this model (ORI121217050).

Technical question

Manuel S. | Jul 25, 2021

Orion Tr Smart battery to battery Charger 12-12 V 30 A. What is the difference betem isolated and non isolated models ?

Answer

W P. | Jul 26, 2021

In most boats and vehicles with multiple batteries (e.g. starter battery, service battery, winch/bow thruster battery), the battery MINUS terminals are connected to each other and to the boat/vehicle ground. The common MINUS eases charging current distribution, but also provides a path for interference signals from one DC network to another. Galvanically isolated B2B devices are used on special boats/emergency vehicles to break ground loops and thus protect sensitive technical equipment from sources of interference.
