Anyone got one of these intelligent vsr looks totally different to usual little black relays, from reviews they seem to be good just wondered if anyone had one on here, £60 inc wiring and fuses on eBay, Abit more expensive then the cheap square black relays but I want something Abit better.

I have one in one of my vans. Been going strong for 7 years now...

One of the best relays that you can buy. You will also need thin welding wire and decent fuses. I have 50A fuses fitted to mine with 120A wire.
Plenty of info on Google.

I'm confused. Please explain. Thanks

cheers guys, i ordered one this morning of ebay with full wiring and fuses as i couldnt be bothered doing all that myself, had enough of that when i used to be a mechanic!
heres the kit i boughthttp://www.ebay.co.uk/itm/251730839507?_trksid=p2060778.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT (http://www.ebay.co.uk/itm/251730839507?_trksid=p2060778.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT)
glad you said its decent and from reviews on web it seems decent too, i kept reading loads of bad reports on the cheap little black relays being quirky and eventually dying so im happy to pay the extra for this.

I only do around 6 miles a day charge my leisure battery every night would the relay work?
-
think it would put some charge in pal but with the little amount of miles i think youd still have to take it off and charge it at least once a week?
-
I've got one of these there great never had to charge my battery but i do a fair few miles....
-
Are these relays easy to fit?
-
I dont really do lot of miles and yet my relay keeps up only once did i have to start the motor and that was a big 5 hour job.

The 110 amp leisure battery on my van took a hammering today with 2 pumps running.
Tonight I put my charger on to it. The battery is only accepting a charge of 3.4 amps and 13.3 volts. If I start the engine, the vans alternator will boost the volts up a bit which means that we can get a slightly higher amp charge, ie 4.9 amps.
It would be interesting to see if this SCR that Cheshire has will increase the charging rate or not. Bearing in mind that a leisure battery should only be trickle charged, about 10% of the battery's capacity.

This is what I used on my system.

I've got one. It's a good bit of kit, does exactly what you expect at high amps.

I always bring a spare battery on the vans so will buy this relay to save electrici hopefully it will work.
-
a nice bit of kit and well worth the extra money-its not let me down yet

What is the difference of this relay to the one that comes with the one that is built in to the circuit board on flow,controllers.is it because the amps are much higher so charging can happen faster

Ok, thanks. I understand now :-[

I find that the alternator starts of charging the battery at about 13.8/13.9 volts. This will 'force' a slightly higher charging rate. Once the battery is fully charged, the alternator will not boost the voltage output above 14.4v. Your charging rate is governed by what your alternator is regulated to, so putting a higher amp split charge relay isn't going to change that IMO.
One of the other issues we have is that our leisure batteries are maintenance free. This means that they cannot be topped up with water. Charging an MF battery too quickly causes gassing of the water in the battery. Battery will be prone to failure due to a reduced amount of water - lower water levels in other words.
There is a number of videos put on YouTube by Sterling which are quite interesting with regard to charging.
Maybe we should be using the much more expensive traction batteries if we want to recharge faster.

This is what I've found in the past tryed all sorts of relays but still need to charge every other night but my van is only doing aroun 6 miles a day thanks for your advice Spruce

We are in the same boat with regard to mileage.
I was told by the manufacturers of the relay that Grippa tank supply, Samlex, that using that relay (Samlex BS100 100a) with not speed up the charging rate of a leisure battery when compared to a 30 amp SCR.
-
I know that this is an old thread, but my 7 year old TEC2 alternator triggered SCR packed up last week. I was shocked to find that this SCR is only a 15 amp relay as I thought it was a 30 amp one like the 2 Brocott SCR's fitted to the boy's vans - the same unit I recommended to other wfpers.
I ordered and received an Altec 140 amp VSR which is very similar to the Durite VSR's that a couple of you recommend. Fitted with 70 amp cable, this unit does appear to charge the leisure battery at a much higher rate than old unit did. The supplier told me that it was probably due to the size of the cable more than anything - less resistance.
However, I have a problem with this unit that I don't have with the smaller Brocott units. I identified that this Altec VSR is bi - directional. The issue with this is that the battery has to be disconnected from the system if you want to give it a supplementary charge. I purposely tucked my battery out of the way as it isn't something I to attend to often as I have a flylead in the back of the van that I plug my charger into when needed. I also don't want to disconnect the battery each time as I have to digital controller attached to my Airtronic diesel heater and don't want to mess on setting the date and time and programs each time the power goes down.
If you don't disconnect it then you have the charge triggering the relay and your starter battery is being charged as well. The trouble is that the charge state of the starter battery seems to not be transmitted back to the charger which means it will charge the batteries forever.
I'm waiting for the supplier to get back to me with a solution which will probably be to put an on/off switch on the earth wire from the VSR. I would imagine that switching that off will prevent the VSR from triggering.
I was wondering if any of you had similar issues with your self switching relays with regard to battery charging in situ.

you will need battery isolator switch or clamp that goes on negative terminal.

forgot to mention that i fitted ctek charger leads with a quick connect plug.

Doing this has saved a few chargers for me as I would connect the terminals up incorrectly sometime down the line.
Battery terminal isolator is a good idea - I've never seen one before TBH. But the problem is that I have an Eberspacher digital programmer powered by the leisure battery which is a pain to reprogram, especially as I boost charge my leisure battery every second day.
We have just found that the Durite VSR is also bi-directional. So if anyone has one of either of these VSR's then they need to remove a battery terminal or remove the battery completely from the van to supplementary charge it.
With further experimentation this morning early, I have found that the VSR sensor is deactivated by removing the VSR earth flylead. So I'm going to order a splashproof rocker switch and fit it to this flylead and switch it off (open the circuit) when charging my leisure battery in situ.
I also found that with the leisure battery isolated, my charger kicked out after 10 minutes to tell me that the leisure battery was fully charged.
I then put the same charger on my van battery and it kicked out in 30 minutes to tell me that it was fully charged. I then connected up the VSR and switched the charger back on to charge the van battery and a charging voltage was also registering across the leisure battery. But my charger registered that my van battery was only 75% charged and nothing changed after the charger was on for an hour. Who can explain that?

assuming that you have a smart charger after bulk charging, absorption phase can take hours to complete as current goes down.
