Routing the Cable to install a EcoFlow 800w Alternator Charger

[Twunt]

I would ideally like to connect it to the main battery terminals but struggling to find which ones they are, suppose I could actually try and look in the manual

In the engine bay on the battery?........Its feeding the cable through the bulkhead that has me confused so the terminals under the passenger seat (RHD) seems best option

Thanks @jaydisc

I have a Ocean T6.1 with 2 leisure batteries, ideally I would like it to reverse charge the main starter battery as I have solar on the leisure.
I have Delta in the boot so I can use it to plug into the electric hook up when I am working on laptop etc..
I am starting to wonder if its easier to forget about the reverse charge and just put it on the rear leisure battery to save the routing of the cables to the boot area

Ooh! With your solar, if you hook the EAC up to the rear leisure, your solar will also charge your Delta!

With 2 leisure batteries AND a Delta, do you really need to be concerned about the Starter? Also, my understanding is that if your leisure batteries are super topped up (as they will likely be due to solar), once the Split Charge Relay opens up, charge will flow back from your ample leisures into your starter.

I’m finding the ability to reverse charge my Beach leisure battery really handy. I can still use the existing 12v sockets but have so much more battery capacity.

It's such a perfect setup for Beach owners!

No I thought the main terminals were under the passenger seat somewhere

Yeah I think I might be going a bit overkill , but I want to be able to run my laptop / ecoflow and Nespresso off grid.
Think I will connect alternator to rear lesuire battery and forget about it.
Might get a portable battery starter .. just in case

I had initially seen 775w at idle, however I turned down to 600w on app as a max as usually on long journeys between battery use, the charge,

Initially at idle I had 775w, I’ve not tested on the move as yet, my intention is to throttle down to 600w as a average input, I switched off leisure batteries and cabin power at the fuse box in rear, the relay is dormant until activated by engine, so didn’t disconnect batts at terminals, made connections double checked all switched back on at fuse box and all seems to work fine
P.S I’m not an electrician or an enthusiast just double checked everything having received invaluable information from the respondents to my enquiry
Thanks again All

Hi I'm interested in this too...did you take any photos of your wiring under the seat...I'd be interested if yes...thanks sounds like a great product...are you still pleased with how it functions? cheers...

 

[Feggers]

To a Chassis ground/earth connection.

I know silly question… why not put the négative cable to the negative pôle on the battery? I’m thinking of getting one of these and attaching it to the rear leisure battery… I already have solar plus a victron connected to the rear leisure battery… would this be a problem to add the EcoFlow alternator as well … my vw is 2009 T5 2.5tdi

 

[jaydisc]

Because out of the factory, all the negative connections to the leisure battery flow via the shunt which provides the battery monitor in the overhead screen. If you bypass the shunt (by connecting directly and not via chassis/ground), you bypass the reporting, and then the screen and battery are no longer in sync.

I have a Victron charger connected to my leisure AND the Alternator charger… both ground to chassis, and the overhead screen properly reflects the flow in and out.

 

[Feggers]

Hi thanks for your reply… could you tell me where you attached the negatives to the chassis ? Was it in the rear battery compartment? Thanks again…

In the rear compartment use the Battery Clamp stud.

Hi there, no im sorry no pics, its a simple connection, the relay is clearly visible and easy to connect to, having removed the seat

Ah ok that sounds simple enough even for me thanks a lot …

Does anyone have any suggestions about how I might route the Alternator Charger cable from the back boot (right) to the front passenger seat (left)? I’ve had it temporarily cabled through the cabin but I’m ready for something more permanent. I want to keep the Delta in the boot and the only worthy space to mount the AC is on the right wall of the boot.

 

[Feggers]

I don’t quite understand why do want to take the cable to the front when your delta is in the boot? My delta sits between the the two front seats nicely…and I will be installing the EAC to the boot leisure battery…and will find a way of running the cable to the front iether permanently or when needed…hope you find a way to do it cleanly… looking forward to hearing how you did it…

So do you want to connect to the leisure battery under the passenger seat? I’m not sure if there will be enough cable length to reach under the passenger seat with the EAC on the right side of the boot, or have you checked?

Ecoflow Alternator Charger 800W

I have an Ecoflow power station and it's been fantastic on recent trips to run the TV and keep my drone batteries charged, but it only lasts about two days. This EcoFlow 800W Alternator Charger looks like a game changer. Just wondering if anyone has tried it yet?

I have an EF River between the two front seats (doesn't affect rotation). The Delta (and Alternator Charger) is in the boot, and powers my fridge, hotspot and more. I have a Beach, so there's no leisure battery in the boot, only under the passenger seat.

Yes, it's my only leisure battery. I currently have it connected and wired up this way (with a bit of slack in the back), but I'd like something a bit safer, more discreet, but I do not know the potential passageways of the vehicle. Here's some pics of the current above-the-floor wiring:



Bonus boot pic:

The Alternator Charger is on the floor behind the Delta, between the Delta and the bench seat. I'd like to mount the Charger on that side wall instead. Unfortunately, the Alternator Charger requires the occasional, highly-technical off-and-on treatment, so it can't be completely unreachable.

OK, I presume you have a Beach Tour with twin sliding doors and 3-seat bench. Running the cable alongside the door is not ideal if you intend to use it. I would also keep it well away from the sliding seat mechanism.

Here is an option that comes to mind, although I’m not sure if it will work. You could try running the cable through one of the middle two seat rails that are not used by the bench seat. I’m guessing the mechanism only uses the outer rails. If you remove one of the rail end caps behind the front seats you can lift up the aluminium covers enough to allow you to push the cable inside. I think there should be enough room inside for the cable. You should also be able to manoeuvre the aluminium cover forward to create an opening in the boot for the cable to exit.
Just a idea but may be worth investigating.

 

[jaydisc]

Yes, correct on all counts. I will take a look and see if access via the seat rails is an option. I also hope to determine if I can get access to that floor subsystem via the passenger seat too, because having it hang out the back of the seat as it is, is also not ideal. I'd like it to all be invisible.

Read the thread with interest even if i dont get all details.

I have a California T6.1 Ocean and often camp in cold weather away from power hookups. My main requirement is to have powwr to run the diesel heater, as it’s the primary device drawing current. I’m looking at setting up an EcoFlow Delta 2 as the first utilized power source, complemented by the EcoFlow Alternator Charger.

The idea is to have the EcoFlow Delta 2 primarily supplying power to house battery consumers thus carrying the liins part of charge sischarges. The AGM batteries in the van would act as a backup, stepping in only when the EcoFlow runs out of power thereby saving their lifespan by limitung the occasions I run them down to 20%.

Is this doable or advicable or shoukd I rethink?

 

[jaydisc]

I need a bit more detail. When you say "House Battery Consumers", what do you mean? The lights, cigarette lighters and diesel heater are all gonna run of the AGM batteries. Obviously, anything you can offload to the Delta, you could, but that would not work for the built-in lights or diesel heater. Those would continue to run off AGM.

However, you can use the Delta 2 + Alternator Charger to reverse charge and top up the AGMs, to give you more diesel heater and lighting runtime.

Yes, I understand that that's exactly the challenge: to offload the AGM batteries with the Delta2 for all "house consumers" like the diesel heater. I was thinking that two reverse diods or something could make the Delta2 and AGM batteries both be connected to, and supply power to house consumers. With the one with highest voltage actually providing the curent. If the Delta2 has a higher 12V output through the cigarret lighter contact (which I don't know), it would be emptied first and then the AGM batteries would take over (or when bigger loads then 10A/Delta2s current limiter is needed). But I can see that it's prob not possible from the thread. My second idea was to have just the diesel heater emptying the Delfa2 first and then have it fall over to the AGMs if that would be doable in some way. But otherwise hooking up the Delta2+Alternator Charger to reverse charge the AGM batteries as you suggest seems to be a alright, losing a bit efficiency I guess but nevertheless nice, particularly access to fast charging if hooked up to 230V.

R is under the seat.

Does anyone have a photograph of "R", so I know what it looks like. And in particular, what does the "Connect here" point look like? Please and Thank you!

 

[Feggers]

Thats a good question … i have no idea what it looks like… but looking forward to someones input…

 

[Twunt]

I ended up attaching mine to the rear leisure battery in my ocean as I couldn’t work out "R" either, works well apart from excess cable and the rear cupboards look a bit messy now
