Thank you John for the isolated and non isolated explanation, I emailed Victron and they told me to check with my local dealer for my needs, they could’ve easily explained it as you have..
Brilliant explanation of the Victron B2B charger, just one thought how do you adjust the charge parameters of the electroblock charger to suit lithium. Wobby1
Hi John and Mandy, Love what you do and watching your posts. Me and my wife have a Motorhome and plan to do the same trips/ adventures once we are allowed out of this mess. However in the mean time I can offer my help. I run my own business which is a Laser Cutting Company. So my offer is if you need anything like brackets, plates from any metal or plastic, I will manufacture these for free and delivery to any PO address you need. Hope that helps
Regards
Barry
Thanks Barry, I’ll keep you in mind for future projects 👍🏻😁
No Cooper, no Mandy, no food, no scenery, I'm beginning to think I'm watching the wrong channel.... Oh, wait... I am. See you Friday! :-)
No scenery right now to warrant 2 vlogs a week, but there’s plenty of work going on in the van for separate videos 👍🏻😁
You gave the best explanation of isolated vs. non-isolated that I have heard so far. Now I get it. Thank you and happy travels.
Using same charger. Gets so hot I can’t touch it for more than a few seconds! Is that normal? I’m using 6awg wire and 60amp fuse at the battery.
I've watched tons of these videos looking for a b2b set up and this one was the first I completely understood. Amazing job, thanks mate 👍
Glad it helped!
me too ....
Hi John,
You can connect 2 of the Victron DC-DC chargers as I have 2 fitted and it works fantastic, I have the Peugeot Boxer 175.
I used 35mm cable to a positive and negative bus bar and fed the 2 chargers from there and they both come on at the same time.
Great setup 👍🏻😁
Ive just come across this video Jon, and its brilliantly and simply explained thank you. Could I ask, do you know if this set up would work straight into a Bluetti AC300 / B300 to charge on the go, rather than using the 12v cigarette socket at 10a. If so it would solve my current headache of working out how best to do this to charge faster without installing a separate inverter.
This video explains how to do that
ua-cam.com/video/BbWF54wjL6Q/v-deo.htmlsi=BTUmN97aDdHcKJra
I see you used 16mm2 cable which is rated about 110A - but the charger is only outputting about 30A. Please could you explain? Also, does the Victron b2b allow you to link the leisure battery to the starter in case starter battery is low on charge. Thanks.
Please feel free to read the other comments where I’ve already covered these questions.
Well explained difference between the isolated and non isolated versions. Great video as usual.
Thanks 👍🏻😁
A good old original gadget video 👍 you can never have too much power 👍😀🐾
Power to the people 😁👍🏻
Educational as always, and thank you for emphasising the need to appropriately fuse/breaker the positive terminals at each of the system (vehicle and house/leisure) batteries - I’ve seen more than a few dubious van installs where the person responsible genuinely can’t understand why they need more than just the one fuse/breaker in the whole system; and then try to justify their stance by asking if I know how much they cost - my normal response is “less than repairs to your van when it catches fire!” Fully agree with your stance on Victron kit; not cheap, but quality rarely is. Stay safe.
Breakers & fuses cost nothing really, they’re just not attractive, and most people go for a nice looking electrical system these days. 👍🏻😁
@@johnmandy Agreed, breakers also have a very convenient benefit: you can use them as switches to isolate systems during installation and testing.
Definitely another item on my wish list for the van. 🙃🚐👍
Hi John. I've got an 06 VW Crafter as a base for our motorhome with 2 x 200amp AGM lesiure batteries, I want to fit a Vitron B2B charger am I going to have problems overheating the alternator when charging at idle speed? If so should I change the alternator ? Taa
It’s going to be fine, as I said in the video this is a b2b charger, your alternator then charges your starter battery as normal. This b2b does not pull power from your alternator directly.
in the phone app on battery setup does it have sealed battery in the drop down menu...and has it got to be 16mm cable starter to dc to dc charger or could i use 10mm cable ....thanks j&m
It has many battery options on the setup page or you can choose your own custom settings. Cable size, length of cable and amps sent down a cable are for you to calculate for your setup.
Hi John and Mandy. We are avid followers of your channel and look forward to your videos every week. Andrew here. I'm after some help please. We are currently converting a 2017 euro 6 compliant Mercedes sprinter. Me being me went and purchased a voltage sensitive relay only to discover that it's not quite as simple as that because our van may have a smart alternator fitted which would render the vsr useless. I'm a bit of a newbie with van electrics so was wondering if you could give us some information on what we need to charge our leisure batteries on the go. We are fitting solar panels but we live in England! . Would this victron device work or do we need something else. Thank you in advance. Two old buggers on holiday. Andrew and Barbara.
Yes, this b2b is perfect for your van 👍🏻
@@johnmandy Hi John sorry for the late reply. Thanks for the info. I will be getting one of these just to be on the safe side. Andrew & Barbara.
cant be used directly from car alternator right? have to be car alternator starter battery and from starter battery plus and minus to the b2b right?
It’s a battery to battery charger, so it can only be used connected to a battery 👍🏻
Just a basic question. When leisure batteries need charging. With the Bat to Bat. In the dark start engine and drive off does the BTB give priority to power head lights , cab fan Demister winfscreen heater and wipers and does the charging current drop to batteries when lights on etc. Cheers from old George
Please read the comments as this has been covered already 😁👍🏻
@@johnmandy ok matey will do. Cheers 👍
I've just installed a VSR as shown on your previous tutorial, chuffed with myself.
Then you go & do an upgrade......ggrrrrrrrrr.
Oh well. :-/
That old wiring video is for basic electrics, the new wiring video coming this Tuesday is all about what you can really get out of your electrics if you need to.
Hi great video, does this mean I can get the kit on Amazon with the Cargo split charge then add a 10amp Victron? I've an AGM 95ah leisure battery just trying to figure the best way to charge it.
One of the best things we fitted to our van . Although with us not starting the van up for a week and it being super cold I tried the in app boost for allowing the leisure battery’s to give me a jump start . Sadly Nop it didn’t work and heck if I know why not
I think you’ve got a different product, this b2b doesn’t jump start, it simply wouldn’t allow enough power through to start an engine
So, I am trying to setup a camping trailer with solar, so it will charge off the car whilst I'm driving. Any idea if I can just run cables from the socket to the battery or will I need one of these? A little out of your wheel house but don't know where else to ask. Ta!
It’s not a tricky question, you just need to understand 12v electricity doesn’t travel well down long wires, most caravans have a 12v feed to power the fridge while towing, it’s around 10-15 amps though, due to the size of cable and distance.
I’d say if you used 35mm cable and used an Anderson DC connector then you could use the b2b in the trailer to charge it’s leisure batteries. So run the pos & neg 35mm cables directly off your tow vehicle starter battery, fused with 100A mega fuse, then put the Anderson connections near your tow ball, get some decent protective conduit for running the cables at the trailer end and allow for articulation, then you can just follow the rest of my b2b install video 👍🏻
@@johnmandy awesome thank you!
Thank you for the explanation between isolated and non-isolated.
Thanks John for another educational vlog, always appreciate them . Stay safe you three
Thanks Damien 😎👍🏻
There's a lot of promo for various 'solar generators' (daft name) which aren't that good. Have you thought about making your own, there doesn't seem to be any UK channels doing that so it would be good to see you try.
When we had the panel van I contemplated building a power wall into the side of the van, but moving & vibrating van caused me too many concerns so I scrapped the idea.
@@johnmandy I saw someone who built an elaborate setup that worked to overcome that but too much hassle for me. I was just thinking about a portable assembly, possibly one with a decent high current charge input, inverter output, usd, 12v dc etc...
Great video John, the mist is finally clearing from my eyes, but I have a question. If the B2B is connected between the Starter battery and the Leisure battery, how can the phone app display the current, including the currect being supplied by your electrobloack, or have I missed soemthing?
Hi John..any chance you could leave a link to that first circuit breaker you showed us? As I want to buy it. Thanks for this vid...I now understand things better 😀
Interesting as ever John. Are you using the stock fiat alternators, if so what's its max current output ?
I’ve answered this in the comments already 👍🏻😁
@@johnmandy Must have missed that one when scrolling about.
Good installation video. Are you using a BMV 712 or just the Victron app and have you considered using a Victron BMV 712?
Hi, a wonderful vid as always. Based on this, I have had a Non-Isolated B2B installed to my 2017 Autotrail Motorhome. I also have a Victron Shunt and MPPT solar regulator. I have a new Lithium EcoTree Leisure battery and they advised me to set the absorption voltage to 14.4V. The installer has bypassed the Sargent Split charging system that came with the van.
I have taken the battery down to 85% and noticed that the B2B starts in Bulk then goes into absorption charging after a couple of minutes. Is this normal behavior? Does anyone know a testing schedule to help determine issues please? Thanks in advance for any help.
I was thinking of changing my sterling B2B to the victron just for the app and connect with my mppt and bmv victron products,
how many amps is the car engine battery fuse?
100a fuse on the starter battery end. 👍🏻
Great video, clear explanation. I have a modern van but with Pb batteries and simple SCR charging set up. I would like to add a Lithium battery and the Victron B2B. Do I need to somehow disconnect my existing SCR before connecting up the B2B? Strikes me I should as if the SCR kicks in first to charge an Li battery , it will overload the alternator by drawing too much current? The Burstner 'block' you had seemed to have 'semi-intelligent' facilities, so it was OK to leave it but not so a 'standard' SCR?
Hi I have a burstner privilege 727 and I’m going to convert the battery’s to lithium and have the schaudt EBL 99K feeding the lead battery’s can you leave this connected giving it’s feed and add the Dc to dc charger as it has a switch on it only gives the option lead or lead gel any help would be greatly appreciated
Can anyone send me a link to the two different circuit breakers as I can't find them anywhere? Not that type anyhow. Thanks in advance
Hi John ,
great video well explained thank you very much.
I have a question:
Will this device charge in both directions? what I mean is, will it charge my starter battery. I live in my van and don't drive very often but I have a good solar setup. Can this be set to keep my starter battery topped up?
Scott 🤘
Hi John,
I've got Toyota VERSO car and tow Knaus Sport 500 FDK and wanted to know can I put a DC to DC charger to run from my car battery to my batteries in the caravan. I know all or most of your content s around the motor home market.? I imagine a larger rated wire from batt /Alternator via Anderson plug not via towing plug 13 pin? I'm going to Paris area in ept for some WCR 2023 and of course will back the Aussies. Cheers Chris the Aussie living in the Netherlands 🇦🇺🍾🏁
So you don't have to run a wire to a starter wire so it will charge when you start the car ? That little plug in pigtail does it. Thats cool. BTW Thanks a million for this video BIG HELP to me .
I've just completed the Victron B2B installation and it seems to be OK but in the Victron Connect App I can't find the very useful 'State of Charge' screen you show with volts, amps, % charge etc on the. How do you get these figures on the Victron App or are you getting these from a 'Smart Shunt' also installed in your system, or the BMS?
Hi John, question about the second charger. I’ve got a victron charger right on the leisure battery. Will it then charge the starter battery trought this DCDC as well? Or is it only (hopefully) one way of charging, and only works when the starter has a higher “charging” voltage.
Best regards, Taeke
Hi great video very helpful
The one area i could not find info on anywhere was my original Sargeant split charger which I had hoped to isolate.
In your video you have left yours still working without apparently any problems.
This has given me confidence to stop worrying about mine and leave it alone.
Thanks
Thanks for the video! So helpful. About to order the 12v to 12v victron orion. How to decide between the 18 amp and 30 amp? I have a 200 ah AGM battery for the leisure battery. Any advice would be much appreciated. Thank you. :)
My small 4cylinder van has a 160amp OEM alternator. My house battery will be 460AH Lithium. Can my van handle a 50amp DC-DC like the Victron Energy Victron Orion XS Smart 12/12 50A DC-DC Charger?
Will this be ok to charge my leisure battery for my window cleaning pumps?
Hello from sunny Playa del Rey, California! I have a question that I think is in your wheelhouse: what do you think about me using Anderson connectors from the Orion to my cute little 50a LiFePo so that when I arrive at my destination I can pull the battery out easily (it actually has a rope handle) and carry it off where I can then use the same connector to hook up to my inverter? Jackery Hack! Or am I just dreaming 😀? I sleep in a tent with a CPAP and would love to not have to run an extension cord to my vehicle. I'm a new subscriber and look forward to combing through your videos this evening. Cheers.
great video!Can you connect it in a 12volt 180watt socket in the trunk and charge a 12volt batterie and a 12v fridge buck there, at the same time???
Hi there, is this ok to use with 3 x 110ah battery’s. Also do you also need the mppt for the solar or does this replace ? Many thanks Ian and ema
Hi mate! I have one of these installed, I don't have a smart shunt yet, I have 2 x 200ah agms , recently been bad for solar and my batteries have Been on 50% , been driving for 2/3 hours and my voltage has stayed at 12.5 the app seems to look like it's working correctly, but the dc charger isn't even warming up its stayed cold after a 2 hrs drive... any help at all man?
Hello, it's so difficult to find a video complet in French like yours ! so very thanks for your video, i try to do it now ;)
Why are split chargers a bad idea now a days ? I've just bought one to put in my 16 plate Renault trafic. Are you saying I should ditch my split charge unit and get one of these ?
A split charger can’t detect the state of charge of the battery, whereas a good quality b2b can offer different levels of charge to allow the best charge to be delivered right up to 100%
@@johnmandy sadly at over £200 and on a budget, not within my reach this time. I have to stick with my split charge unit for now
Bit of a strange question. So I bought a victron kit. Which has come with the isolated charger. Because my negative on both my batteries go the van metal work can I run both negatives from the charger to the body instead of running a negative from the vehicle battery to the charger?
(Reason being I’ve already routed my positive cable without realising I got the isolated version) 😂
Hi, such a useful video and sorry if you've already answered this somewhere - I did look! At 11.10 mins you show a state of charge page on your app showing loads of useful info such as current and power output. I can't find this anywhere on Victron Connect!! Could you please give me a nudge in the right direction...
Hi John I hope your keeping well in these tough times.
I’m looking at upgrading my setup to one 100amp lithium battery and one of these. Only use the van every other weekend really.
You’ve answered all the questions that I had in my mind as you usually do.
I can always rely on you and Mandy to help me out with your videos.
Thanks for everything you do and Keep up the good work mate.
So glad to see this video- I have the same charger but cannot get the blue tooth to connect. It is asking for a numerical code- but the codes has letters…… any suggestions? Thanks in advance!!
Hello, is there a way to limit the current? if I have a Li Ion battery to charge, that can take 200+ Amps, how can I limit the output current in order not to blow the fuse or overcharge the alternator, charger, cables?
Great video, very informative. Thanks for sharing
Hi John & Mandy, Thank you for sharing and detail information for the connection and config! I have the same setup but for the 12 | 24 | 15 (car-victron-(battleborn 100)- goalzero 1000). In your set up how can the victron knows to not over withdraw from the car battery?
Will this drain youre starter battery also when the leisure battery is getting empty with this setup?
Cause I want to keep them apart so I can always start my engine
Thanks in advance for youre cristal clear video!
Greetings from the Netherlands
Brilliant know I don’t have to read the manual 😂great vid 👍
Thanks 👍🏻😁
Thanks, this is very helpful. I am just starting with van electrics and leisure batteries. I was told not to get VSR as it's old now.
Oh Id just say to anyone, use the hydraulic crimp tool like John has, the others including the cheap hammer style dont work as good and can result in a loose connection, not to mentioned where are you going to hammer it properly if you are in the van whilst fitting??
So a 30amp fuse is good?
Breaker is best or a mega fuse, but not a blade fuse, they’re not suitable.
Thanks John. We bought one of these for our conversion. You made sense of this for me and I'm not fitting it 😂
😁👍🏻
ps still gave you thumbs up thou
Very good tutorial, wouldn’t be worth it for people like us who don’t live in the van, solar and onboard split charge has always been enough, even if we go away long term it’s usually 1 night then drive etc so we’re usually full. Cheers tho good vid! 👍
👍🏻
Great information there John. Thanks so much. I have installed the same after watching your video. However somebody has told me that I have fitted the wrong circuit breaker. I fitted a 30amp like you showed. My Dc to Dc is 12/12 30amp. Should I be fitting a bigger breaker? Thank you.
If you copied me then it’s fine, ignore the other advice.
I was told the same thing? Now I am worried? 🤷♀️
@@juliep4193 I think John knows what he is talking about. 👍
@@Wizardinthewild Yes, I trust John. My problem is... I don’t have a great deal of knowledge when it comes to amps and alternators. I know enough (I think) that the guy who installed my 12/12 30 charger used 10 awg wire, (I am not sure what that size is in UK?)which is wrong, so I am re-wiring it myself now. My 30 amp breaker kept breaking after a few minutes. Which I didn’t understand? I am hoping it is due to a much to small wire? And not the fuse? I will stick to the 30 amp fuse I have and see what happens? Do you have any thoughts? I have a 2019 Ram Promaster and I am “pretty sure” it is a 180 alternator? Thanks for your response. I needed that encouragement to move forward on this. I haven’t been using the charger.
When I say fuse, I really meant breaker, I have the same 30 amp one John is using.
Thank you John. Well explained, like always. Big thumbs up! 💯👍
Thanks 😁👍🏻
I have one in my Jeep install and love it - reliable 30A at 12V whenever the engine is running. Thanks for the review!
Very informative John! I do have a query that I hope you might be able to answer. Can this (or any victron) B2B reverse feed and charge the starter battery once the leisure batteries are full if you have an additional feed into the leisure side such as solar or 240v charger?
No this can’t reverse charge. There are dual mppt controllers that can do that from your solar setup.
I’m just about to install the same device (except in non-isolated type) in a travel trailer. I want to put a switch on the B2B charger so I can easily turn it off - for example if caught in bumper to bumper traffic on a hot day. My interpretation of the manual is that all automatic functions will still be intact when the charger is on. You seem to be under the impression that they might not. Am I correct?
The non isolated in a trailer? How will the chassis grounding work to the vehicle?
If your engine is running the b2b will charge the leisure battery, makes no difference if the engine is idling or your driving along a road. It’s all in the video 👍🏻
@@johnmandy1) The truck and trailer chassis grounds are connected. 2) Alternators cool their selves by way of a fan that spins along with the alternator - so the faster it spins the better it cools. When an alternator gets fried by a dc2dc charger (which definately does happen) it's often caused by heat. So turning the charger off during long periods of idling - especially in hot weather - could save the alternator. Also if the alternator (or other part of the charging system) does fail you always want to turn off as much of the load (AC, stereos, etc) as possible when you notice an issue. It can be the difference between driving to a shop or having to be towed.
Also I might add that my truck came from the factory pre-wired with accessory switches that makes it extremely easy for me to do this.
Hi John do you have a components list for this set up.
Thanks
Simon
Hej!
Wondering about a few things:
- My EBL is older but it charges my car and house battery when it is connected to 220v.
Wouldn't this trip the B2B charger to "open" the circuit? Since then the car battery voltage goes up.
- Is a standard alternator sufficient to supply 50 amps for charging (20a+30a) when for example car lights (250w) + 12v absorption fridge (220w) is on?
Our alternator copes just fine with this. The b2b sees the alternator voltage, so it depends on your ebl charge voltage, but the ebl hookup charger does NOT cause my b2b to kick in.
More great advice John..........well explained and easy to follow instructions.......stay safe........thanks for sharing
Thanks 😁👍🏻
Hi John....
Whats the difference between a 12v / 12v charger and a 12v/24v or 24v/12v....don't understand.
I will be using a victron on my 22plate fiat but which one do I go for....?
Thanks mate.
The voltage would depend on your van, maybe it’s a 24v system so you’d need a 24v charger. For your fiat you’d need the same one I show fitting here.
Well done, I installed one of these just before crimbo, Ive got a polinovel 200ah battery, and had researched this for a long time online as to how it fits with my system and split charge etc etc before fitting, and I can say your video is the best around online for this piece of equpment. Cheers
Hi John.....You mentioned if you had the room you may have gone for the 60amp b2b....I've put a 30amp Sterling unit in my Mhome just before this video but may buy a Xlwb sprinter so have the space for the 60amp....I'll have 500w Solar and 200ah Agm and be off grid mainly....Keep up the Fantastic Work
Thanks 😁👍🏻
the only person who sheds light on isolated and non-isolated
I installed one in my friends vw camper van yesterday, literally,so him being the end user I shared this video to him. Thank you for this video!
Hi John what would I need for a lithium set up I’ve currently got a truma 100w panel with dual charger and banner leisure battery.would I need to change to a b2b dual system if I changed to lithium or would it run off my truma dual charger.some lithium say their a drop in replacement?
I’ve got lithium batteries, so you could replicate my system. The b2b charges the battery on the output, it doesn’t charge the starter battery 👍🏻
Is their a dual charger that will do both cab and leisure batteries.with a lithium set up?
@@mikespeers8281 cheers Mike
Hey! Great videos...
Probably a simple question but I see your using a 30amp breaker... I have bought an 18amp Victron B2B charger.. Would I use an 18amp breaker?? and then for connection -- what size cables do I use... I'm a Confused follower... lol
Thanks for your input :)
I use a breaker to protect the batteries from a cable short. 30a breaker is fine. Use 16mm cable for less than 5m or 35mm for a longer run.
How do I know if I need to upgrade my alternator? I got similar setup to you (but in a 2006 Renault Master based Motor Home, built in Calira ~11A, I think, and Renogy B2B & MPPT 30A)
Please read the comments as I’ve answered this question already 👍🏻
Great video. I have the same B2B but have never dug into the settings and realised it's set up for lithium when we have AGM so I will get that sorted.
That’s good then 😁👍🏻
Hi John, thanks for the video.
just to clarify . . . .
you say you have "20a b2b electronlock." - so 20Amps from the OEM charger
and now the new 30A Vicrtron DC-DC - so 30Amps from that. (so 20A + 50A + solar? = total?)
but @ 11.11min the BMV is showing 29A into the battery bank . . . . (you said that was from the OEM charger, but its 20A max?)
Then @ 11.32mins we see 51A going in to the battery bank? . . . you said that extra 20A was from the Victron, but its 30A max.
whats the discrepancy? . . . was the Victron supplying the 30A we see first? . . . the the extra 20A from the OEM charger? (50A ttl?)
thanks again.
im off to watch the Diesel heater vid now. =]
the extra 9A could have been the solar controller, i explain all this in the video.
Thanks for good explanation of device, and info video on installation.
excellent video thanks. I worry about possibly overloading the alternator , will the Orion prevent this ? with any old alternator ? No need for a temperature sensor on the alternator ?
Hi John. I know this video is 10 months old, but I'm about to install a LiFePo4 battery pack setup in the back of my pickup truck. The Battery box will be removable (Connected to the truck via an Anderson Plug). The box will hold everything, Victron DCDC-30a charger / batteries / 1500w AC inverter etc. My question is: will the Victron DCDC-30a charger hold on to its setting when I unplug the box from the truck or will I have to input ALL the settings again when I re-install the box back in, sort of like, if the main 'cranking/alternator fuse blew and cut the power off. (I'm using the box as a portable 'Power-Bank' for site work where mains power is not available). I can't find any info on this so any help greatfully received.
That’s a question for Victron as it’s not something I’ve ever done.
Hi John, I have 2 queries regarding the Orion dc dc charger, mine “never” charges above 25/26 amps and that’s reading from the Victron smart shunt, the other question is I’ve read on UA-cam it’s best to connect the charger “opposite ends” of battery bank to your “load” connections? In other words I have 3 AGM and my charge cables and Load cables are on same bus bar as opposed to what’s suggested, the guy reckons that the battery with all the connections “gets charged and loaded” quicker than the all three equally? Does that make any sense? Thanks
All I can say is the way I wire my systems they work perfectly. Your shunt will only show you what's being used from the battery and supplied by the B2B so it's not a true gauge of what the charge amps are, for that you need an amp clamp.
I have 2 x Renogy 50A with built in mppt, it also has Bluetooth with a plug in, it has the advantage of charging the starter batteries when it detects the leisure batteries are full. In the UK 100 amps is great.
Our solar setup chargers our batteries once the hab batteries get to 100% 👍🏻
Do you have a link to the non isolated charger on your website? id rather you make a couple of pence from the link, for doing such a good video
I don’t as it’s not something I use. But here’s an Amazon link for you amzn.to/3otq0Dn 👍🏻
Hi John, why don't you use 2 x 30A B2B's in parallel? No problem for the alternator and will charge twice as fast.
As stated in the video, we’ve got two b2b’s in this setup
Great video John
I’ve already got a Sterling so I made sure I watched sober tonight. Couldn’t do with a Victron turning up.
P.s firing up the heater this weekend.
🤣🤣
if we forget the password... What does need to be done ?
Very good video John. Thanks sharing. Will be Handy later too uses
Thanks 👍🏻😁
ThankU John for great explanation . How I can finde de second isolator you showed on video. The square one ( looks like Lego pieces) with red top and little trip switch??
And other cuestion what cable you using it’s a 25mm2 plug input to Orión, and 16mm2 Output??
Cheers&StaySafe 🛠🚐✌️
John can answer your question better if you follow us on Instagram & the send a private message. Thanks 👍🏻
Hi John I thought the BTB charger only needed 7volts and above. Why is not on all the time. How does it know when the alternator is on. I thought is was for smart alternators. Mine can struggle to get above 12v output.
Cheers Dale
It sounds like yours is faulty. They’re for any alternator, they detect the alternators voltage.
Be careful with those circuit breakers if it's not a very high quality one.. I found out They can get hot or trip at different Amp. There is videos of it...
I’ve warned people about this for months now 👍🏻
Hi John! Great video. Where did you hook the positive and negative leads to on the house battery side? I appreciate any help, thank you.
We’ve got a full advanced electrics video which includes a downloadable wiring schematic 👍🏻
Hi john, My motorhome is nearly classic lol like me yet I have the old system of leisure batt under the bonett being fed from that dreaded switch relay from main alternator. I thought it would be wise to move the battery location inside the cab for cod weather etc. In a old 1990 fiat would this benefit me and and should I hook a soar panel too it. lol If I did would the victron be of use to my van at this old age. I am trying to keep the van original yet modernised with electrics TY. Hope your back safe and sound . Typed from desktop this time as for my old Mi PHONE predictive text is bad
This b2b charger would work fine in your van, it’d take less power than the charge relay you have, so less impact on the alternator.
@@johnmandy great! will look into it more. thanks for your time to research that John or Mandy if you made her do it lol. if it works I will buy her a `11v hairdryer for xmas.
HI John great video as always..
Which EBL have you got? mines a 119 and it doesn't have a Lithium setting..
I also saw on a RoadPro video that because the EBL or equivalent has to supply the fridge when travelling there ain't a lot of amps left for charging..
The fridge only takes 12amps, the electroblock as you saw in this video delivers just over 20 amps and it backs off way before the battery is fully charged as it can’t reach 14.6v and that’s the single reason it’s not great for charging lithium, but it can still be used. 👍🏻
