You guys have the best wires for that. Bought wires in your store for my Victron setup.

Great review ! thanks i need this, got a question i got the Anker powerhouse 757 my XT60 input is 30V 10 AMP max what type of Victron do you recommended ? or can change the amps in the Victron Orion 12/24-20A non isolated to 10 amp ? or do i need to buy the Victron Orion-Tr 12/24-10A (240W) isolated

Informative, good labeling and a clear, direct presentation

An excellent and informative Video, thank you. Lots of technical information delivered in a very friendly style.

This is a great video. If you have a Victron mppt and panel going to main battery can this be used to take the 2nd output from the mppt to the Orion? The 2nd battery is charged when the vw bus is running via the ecu as it's a factory 2nd battery. This is to divert solar power from the mppt to the 2nd battery when the bus is stood up and intention off? 😁👍🏼

When you set up battery type, is the setting for the output or the input battery?, or is there a setting for both? Thanks.

another great video, any chance you could do one on the multiplus II?

Very good video thank you, I currently have a PowerPart PDU and when I start the engine there is a click in the PDU and it turns off my motorhome electrics, except for the Fridge. I would like to replace the PDU with separate units, one of them being this charger. How does this work when the engine is running, does this charge unit stop charging and let the engine take care of it? Also when I plug into a hookup and the engine is off, do I charge both the leisure and vehicle batteries with this?

[JulianGriffiths]

Brilliant video, please could you share the equipment list please and what solar pannels would you use in this setup

[fvgcss]

Do you have a link to the video that shows the entire equipment list dor the set up on this test board?

[ivanwayne]

This great thanks! So you are charging two house batteries off the Victron DC-DC charger though the bus bar?

[ElizabethEstevez-bhun]

Thanks for the video. Just to be clear, do I use a negative 16mm wire from the Ground on Orion to an individual grounding point on chassis or must it be same grounding point as leisure battery?

Trying to figure out if something like this would work for me. I'm currently running a dual battery setup with an H6 Optima Yellow Top as a house battery which is isolated from the main battery with an automatic isolator. Charging voltage is usually anywhere from 14V to 14.8V, but seems to charge closer to 14V most of the time. My Bluetooth battery monitor started showing signs that the battery wasn't holding a decent towards the end of December. I finally had to the pull the house battery and put it on an Optima 400 charger/maintainer this weekend. I'm sure that sulfation occurred because I had to charge and drain it multiple times before it would hold a good charge. It seems to be OK now, but I was wondering if a DC to DC charger would work better.

This is on a 2017 Chevy Silverado. DC to DC charger would be installed in the engine compartment (if that's ok). The H6 Yellow Top is a 72 AH AGM battery. Recommend charging current:
Alternator:
13.65 to 15.0 volts, no amperage limit.

Battery Charger:
13.8 to 15.0 volts, 10 amps maximum, for approximately six to twelve hours.

Cyclic Applications:
14.7 volts, no current limit as long as battery temperature remains below 125°F (51.7°C). When current falls below one amp, finish with two-amp constant current for one hour.

Rapid Recharge:
Maximum voltage 15.6 volts (regulated), no current limit as long as battery temperature remains below 125°F (51.7°C). Charge until current drops below one amp.

Float Charge:
13.2 to 13.8 volts, one amp maximum current, time indefinite (at lower voltage).
Strictly adhere to all limits.

Trying to decide if one of these DC to DC chargers would be better for me and if so, which one would work best for me.

Good morning and thank you for the video. Currently my motorhome has the services battery not connected to the chassis of the vehicle. In order to use an uninsulated DC-DC, I would like to connect the services battery with a properly sized cable to the chassis ground. Do you see any contraindications to doing this? What problems might I have?
Thank you for the feedback.

[PiovascoCosimo]

Hello, thanks for the info!
I have 2 questions:

-Witch fuse put in/out in the Orion tr Smart 12/12-18 ? I put the 20a in both the way, it’s correct?

- it’s possible when the engine it’s off charge the motor battery from the solar panel that charge the service batterie’s?

Thanks again for the info!

[newsnowlancashire]

If you have 2 leisure batteries how do you wire them?

[januszpolt]

Hi, will I need an isolator in the car with a grey Anderson plug? We have this dc2dc charger in the caravan

[mranderson]

so these chargers will cut the 2nd off from the start battery when the car is not running so you dont have a flat start battery?

[benshke]

Quick question, in the dc dc charging from starter battery to living battery if the engine is running and the starter battery gets disconnected does the dcdc charger still works? Could you test this? Been searching for days on info on this on the inter webs and couldn't find any info.

[PiovascoCosimo]

Hello, nice tutorial! It's possible whit the dc dc 12-12 /30 charge the Motor Battery from the service Battery when the engine it's off and the Service battery it's full and connected at the 220v charger or solar panel solar? thank you very much
