A previous motorhome had a Battery Master (fitted when Growler was installed) and I was very happy with it.
Last year we bought a new Dethleffs and it has the Schaudt EBL 119 and 2 leisure batteries. As we all know this year has been a bit of a challenge for batteries. The motorhome is kept in storage under cover so solar is not much use. I can arrange EHU, at a cost to me.
Prior to the motorhomes first year checks I enquired if they could fit a Battery Master. After some enquiries they came back and said it was not recommended as it may "upset" the EBL119. Not sure I agree with this after reading all the positive comments on here. I do not want to fit one myself as I do not want to do anything to invalidate the warranty. My gut instinct tells me to find someone who will fit it.
Anyone else had this response?
 
I had a battery master fitted to an ebl with no problem. What did upset the ebl was connecting a solar panel direct to the habitation battery, that really confused it. It was only happy with the panel connected to the ebl using the schaut solar regulator.
 
Not sure why you would need to add a battery master?
Not going to help when van is stored
Try a couple of trips out and see how things go

Does the ebl119 have its own built in battery master equivalent?

The next question should have been “why”

”Trickle” charging the engine battery, using the leisure battery as the supply doesn’t affect anything.
 
Eddie knows far more than me about the Batterymaster because his company designed it. I had one on an earlier van but Van Bitz declined to fit one when fitting a Growler system on my last van because it was unsuitable or rather unnecessary for technical reasons (there was already some sort of cross feed arrangements between the two batteries).
However in appropriate circumstances the batterymaster works very well. However it does use up a small amount of electricity in the process of monitoring the voltages.
So my take is that it is that the Batterymaster is very good in most circumstances and unlikely to do harm. However there may be some cases where it is not neccessary.
 
The battery master has proved invaluable over this lockdown period. 22 weeks with alarm / tracker and radio memory plus all the other drainers on, and the cab batt still at 12.9 v when i eventualy got over to see it last week. All kept topped up from the leisure batts. No ehu just leisure batts and solar.
 
I would not take too much notice of what the dealer says. I am not too impressed with the level of knowledge of many of them. Their function is to flog their stock. Go by what Eddie says.
Unfortunately this is common among retailers these days, try asking for advice in any of the major electronics stores, they haven't a clue about the things they sell. Trouble is they would rather give incorrect information rather than admit to be anything short of all-knowing.

"when on mains EHU", so what happens when not on EHU ?

It effectively links the starter battery to the habitation batteries so increases the capacity that the alarm and tracker have to drain before you are in a "no start" situation.

Standard dealer bo**ocks when they haven't got a clue.
Just connect the BM output to the starter battery connection on the EBL solar block.

That just suggests to me that somebody doesn't know how a Battery Master works vs whatever is built into the EBL.

I am no expert but I would say no EHU it does nothing the same as the CSB2 in the CBE units.

Similar thread on another group where a member was fitting 2 large panels and the output exceeded the ebl recommended maximum. I had a 130w panel fitted but the electrician suggested fitting a battery master and bypassing the ebl which I agreed on, no problems in 3.5 years

The limiting factor for wiring solar via the EBL is the plug & socket connectors they are only rated at 15 amps. I have 300 watts of solar wired via the EBL without any problems, in theory they could produce over 20 amps in ideal conditions for an hour or two a day in practice highly unlightly.

Its not likely the connectors would suddenly overheat over 15A anyway. I have 400w solar and more than 20a is a rarety, though mine is wired directly to the leisure batteries, via a controller of course.
