Battery charger / split charge relay

[Tonydom]

Hi guys got a question

should my split charge relay open when I have a battery charger connected to my leisure battery as I have noticed it comming on when the battery charger is on. If this is normal will it be Charing my van battery as well.

Thanks

That doesn’t seem right. Unless it’s a battery master type that is meant to do so.

It would be more normal if it was the other way round......One of my vans would open the Durite vsr if I hooked a mains charger up to the van battery, thus also charge the leisure battery.

I think you mean close, i.e. close the contacts.

Hi Tonydom

On my self built VW T4 camper, I had a voltage sensing split charge relay which was bi-directional, ie if it was on hookup, the higher voltage on the leisure battery would trigger the VSR and charge the engine battery, and conversely if a charger was put onto the starter battery, the VSR would trigger and charge the leisure battery as well.

Think about it, it's a handy feature if the charger is powerful enough to charge both simultaneously as in 10% of the combined capacity or more

Thanks guys I had an idea that the charger would charge the leisure battery if connected to van battery I had no idea that it could work in reverse

yes i think most vsrs are bidirectional

Yes it’s normal I have fitted loads of the attached pic and they do this.
