Is it worth fitting a battery master (1 Viewer)

[Sue]

Our van is in storage, even though we go every 2 or 3 weeks we are finding the vehicle battery is too low to start. We also have a solar panel and the display tells us the leisure battery is if is fully charged, but it can't be charging the vehicle battery.. .?
Can anyone suggest the best way to deal with this?

Yes, fit a battery master.

Agree battery master. There are also many ways to connect your cab batt to solar, but it depends on which system you have. Mine you cannot do have bm from the bitzmeister.

Hell yes, we have one fitted. Best bit of kit you can ever fit!

 

[Camdoon]

You have answered you own question. The real question is why anyone would build a Moho without the ability to charge the van battery when needed.

Fit a Battery master. An essential item if you have a solar panel.

Don't think twice - just fit one. If an electrical numpty like me can fit one, so can you.

So satisfying when that little light glows red and you know your engine battery is taking the excess charge.

Yes it's worth it. Never owned a van without fitting one.

Disclaimer our shop sells the Battery Master cheaper than anyone.

Surely it would be easier to connect the starter battery to the solar panel controller ?

I'm no expert by far but unless you then had a means to allow the controller to treat the van and lesiure batteries differently you'd drain the starter battery when using the habitation circuits. A diode wouldn't solve that problem because the controller needs to know the battery potential difference. Unless controllers are much cleverer than mine I guess

So...it sounds like all battery masters are different, so,what is the difference between them..anyone?

Which did you fit?

There are only two I know of, Battery Master and the Italian one I have by CBE. No significant difference between them.

There are probably many different controllers, mine is a Morningstar which has separate outputs for leisure and starter and splits the charge either 50/50 or 90/10.

IMO if a motorhome has a solar panel and a leisure battery fitted then every MH should come as standard with a Battery Master...they are essential ...been down the same route with having van in storage then after 4 to 5 days passing click click dead battery, had solar but no BM, fitted one via recommendations on fun and never had a flat battery since, in fact I wish I would have took it off when I sold the van....got a CBE fitted now, think its the same thing but cheaper and still does the job

Unless you have a dual regulator similar to

Battery master, took me 10 minutes to fit mine, just 3 wires
