Which "Battery Master"? / D+ Needed?

[CAB96]

Chrome does the same, I will see if I can find somewhere else to purchase. does vanbitz website have a shop? Sorry, I seem to have hijacked the thread here - I will hunt one down somewhere.

Welcome to the forum PsyMan .

I imagine it's only available through the forum shop to paid up subscribers.

Vanbitz don't seem to have a webshop as such, but if you give them a call I'm sure they would sell you one.

Good morning everyone. Apologies as I don’t mean to detract from the thread either but I also used the form Eddie linked to order a Battery Master late last week. I didn’t get any kind of acknowledgement and the payment hasn’t been taken yet. I am not sure who deals with the order once the form is submitted; can anyone advise how I can check the form has been received please.

I’d like to add I am not being critical in any way, I would just like to be able to confirm my order is in the system.

If you have the Victron Orion 12-12 30, it is definitely possible to set it up so it triggers only on the D+, not on any voltages. But you have to go into the settings and change it, I think its default settings are voltage sensitive. As I recall, it's the opposite way round to what you'd expect. The voltage sensitive settings are termed 'engine running detection' or something. You have to override that, so that it triggers only on the D+ signal from the alternator. So you want to turn the 'Engine Running Detection Override' setting to 'ON'.

In a motorhome there will usually be a convenient D+ signal somewhere, without having to go all the way back to the alternator. It is used for various things, including switching a 3-way fridge to 12V when driving, and the step alarm or auto-retract when the engine starts.

There's almost certainly a D+ to the 12V distribution/fusebox - what make/model is it? Should be easy to tap into that.

Thanks - I have found the D+ signal - my "bloc" had a spare pin that provides it (see my other post about getting the plug pins!) but I'm confused about how to set the B2B and how to wire it.
Section 4.8 of the manual seems to show a picture of the "charge" signal (the diagram shows an ignition feed, but I presume D+ is the same) connected to the "L" pin of the B2B, but it also shows "L" and "H" connected together, which would normally be unconditionally turning the B2B on. So when I turn off engine shutdown detection in the app, the connection between H & L makes the B2B charge all the time.

Mine is set up using the H pin connected to D+ and engine shutdown detection disabled. The jumper wire between H and L must be removed.

Yes, that's exactly what I expected to do, however the diagram shows H and L connected together, and the paper manual (which came with the B2B, and is different from the online version) stresses that it's necessary to include the link as well as the D+ input. Thanks - I'll just go and get my screwdriver
