Renology Dc-dc Battery Chargers

I had a quick look at these but after bothering @travelvolts over the last day or so have just this very minute placed my order with him as he was really helpful and for me, that goes a long way :)

Oh, for the record I went for a Victron Orion charger from him.

Always happy to go with recommendations, I'm new to the forum and don't know @travelvolts just yet. What was it that swayed you, having a recommendation forum contact you can trust for unbiased information or the product itself? (I'm assuming for the former)

My pop top is due in this week, so after that I'll be starting on the planning of electrics, (pop-top will already have a 150W Solar panel mounted.

@travelvolts is a well known and respected member on this forum, not only that, but far more importantly in my mind, was that he was prepared to spend a bit of time with me on the phone talking and guiding me through my options :)

Thanks for the recommendation, I'll be on the blower to travelvolts as soon as my van is back from it's surgery.
 
Hi all
I know this has become a popular item now and I have just upgraded to the 50A version. However. After the install everything looked OK. A week later both my Renogy Lithium batteries are dead. The alternator light is constant red which I believe is correct, the Service light shows green??
Checking the app the charger showed boost mode and bugger all amps or watts being put out. The battery mode is set to lithium and the smart alternator wire connected and showing a current when I checked it.
So why no amps going into the battery and why did they fully discharge when not used and van driven everyday to work.
Ps. I'm currently charging the batteries via a charger and both excepting current so apear to be charging OK.

Need an idiots check list to go though to try and find out what's going wrong.
Thanks Grant
 
Ok
Just had another look. Batteries are charging OK from my car charger so they look to be working fine.
Now the DC charger is putting out 17amps or so according to the app. The batteries are showing a minus figure in amps. Basically with the ignition on I get a 5amp loss and with the alternator running even more.
What have I done wrong for achieving the total opposite of charging :thumbsdown:
Thanks
 
Connected it the wrong way round maybe? Can you post a photo
 
Hi
After a sleepless night, I thought that could be the obvious answer. Glad I have all the Bluetooth app info to see what was going on. So traced the wires back through the rear seats with the aid of Mrs Blits and... Yep got them crossed over under where I couldn't see very well and wired them to the controller the wrong way round :x3::whistle:
Thankfully just Human error.

Thanks
Grant
 
Good to know that the batteries and the DC/DC charger survived this mishap. I think it says something about the internal circuit protection.

Now you've just got to have a good look around the van for those rogue Ahs, they must be hiding somewhere :)
 
Yep the BMS kicked in and saved the batteries. Didn't have any problems getting them going again, no BMS to kick start so not totally flat flat. So technically I saved my self £100+ by not killing a new lead acid battery ;)
 
I have a renogy 50ah lithium battery that is not accepting a charge.

Renogy 50ah lithium battery not accepting a charge

I have a renogy 50ah lithium battery that is not accepting a charge. I have spent a lot of time (frustrating hours) on webchat with Renogy. They are now suggesting that I buy a Lithium charger with re-activation capability. They have one on their website but they asking £129 for it!. I spent...

Hi,
Can I ask where you got your D+ ignition from please. I’m trying to connect a Renogy 60amp b2b charger but not sure where to get this connection from. Any help would be much appreciated.
Thanks
 
Covered in quite a few threads now, there is no real D+ on a modern stop start engine.

Any ignition live circuit will be fine. There isn't one under the seats so you'll have to put a feed in from the dash fusebox.

If you are really worried then you can use the BCM charge signal that the OE relay uses which will respect things like Start Stop cycles. That's very easy if you are replacing a factory second battery as the feed is right there under the seats. If not then you have to put your own feed in, get to the BCM, add the additional connector and get something like VCDS to enable the signal. That's a lot of work for a marginal gain in functionality.

If you are hyper concerned about the possibility of the DC-DC putting a high load on startup with a low starter battery just put a switch or small fuse in the ignition live feed somewhere accessible, then you can turn the charger off if you are ever worried.

Hi all, just installed renogy 50amp dc to dc charger everything working fine except alternator light not on when engine running but it's still charging my leisure battery according to renogy home app. Smart alternator T6.1, ignition wire connected ?
TIA

The lights on mine never made sense either, but it charges as it should for the last two years so I stopped worrying about it.
