    Thinking of getting one of these, Is it a DIY fit or will I need to get it done somewhere professionally?

    Obviously DIY, mean's reasonable understanding of following instructions. :Smile:

    After 3 days of me trying to put up my awning without sucess and then you do it in 10 mins I think you should be capable of fitting this yourself.

    the sterling battery to battery unit

    I presume you are talking about taking power from the alternator to boost the domestic battery?

    It may be worth a call to VanBitz .. they fitted my Sterling Pro-Combi Battery Pure Sin Wave Inverter...

    If I am right the unit just goes on tot he engine battery and not the alternator at all.. it ten is connected to the domestic battery to send power to it.. it fools the alternator in to thinking the engine battery is not fully charged and keeps the power coming so it charges the domestic battery..

    On our RV we have a 140 hr alternator and that kicks a lot of spare power across to the domestic side, but winnebago has a set up for this to happen as the norm rather than an add on kit.

    Have you met Haggers and the Smurf tattoo?

    Care to reconsider.

    sorry bob, If im right your not right :Eeek:
    Think your referring to a Battery to Battery charger http://www.sterling-power.com/products-battbatt.htm

    I on the other hand am referring to one of these

    no link in your post Paul

    There was no link in your first post Paul... I presumed you were talking battery to battery.. but I have looked at your link for the alternator .. It is designed for boats if I am not wrong.. that would in the normal course of use run the main engine to charge the batteries as few would have a generator on board... but a great idea.

    As said Winnebago already have a unit that diverts excess power to the domestic side and via my NASA I can see what that is after it has topped of the engine battery... but looks good.

    an expensive voltage regulator,that fools your alternator into thinking your batteries are flat and will put out a higher current for longer:thumb:
    but the inexpensive method i use on my 12 genny does the same thing:thumb:
    and can be installed on any alternator:thumb:

    Know your only helping Bob, but the key was in the title. :Wink:

    Novel idea. If you never have hookup then it might help by boosting your batteries more than the alternator would. Otherwise it's probably solving a problem you do not have and in turn offering the joys of many new problems you've never dreamt of.

    KISS.

    now i am looking at it, why is the battery to battery charger that bob describes any different?

    The B2B will do essentially the same job Paul but is a lot easier to fit, have you looked at where your alternator is located?
    speak to Mark (CLS) he fitted a B2B on his own motorhome at Chester and the air was blue on occasions:Wink:.

    OK the last blog was over a year ago

    OK Paul.. transcribed the would alternator to Battery to Battery...

    I also get extra power when the Sterling kicks in once I start the genny.. I can get the same sort of boost that the alternator to battery gives.. Sterling has been applying this kind of gismo to his other product ranges ... the Inverter he does (PRO-COMBI) as in the name Combi is not just an investor but a battery charger that can take power from a Genny or an EHU and can put one hell of a boost in when it needs to get the batteries back on line. Similar control panels in the link as is on the Combi units.

    But as said KISS unless you really need that massive power why do it? boats can have many many batteries all over the hull and that is the advantage of that system. All of Sterlings bits and bobs come from the marine area and have been then applied to motor homes.

    Bob... p.s Sterling products work well.

    I do hope their products are better than their proof readers, some alarming spelling/typos there.

    Anyway, I'm beginning to think boat here. Where they don't have hook up.

    This takes the 13V from the starter battery and boosts it to 14V+ to fully charge the leisure batteries. But if you regularly go on hook up your mains charger will do it for you.

    Your first choice booths leisure AND engine battery.

    Go buy yourself a new iPad instead, much more FUN.

    Ok Brian.

    I can not remember the last time I had hook up.
    At present I use my genny after a few days to charge my batteries when down. At this point I am able to put in about 15amps from my genny. meaning running it practically all day will get my battery bank back up.

    so option with the alternator to Battery charger from sterling would mean that I can get up to about 50amps by running the engine, so running the engine for an hour and coupled with my excellent solar panel will allow for recharging quickly.

    Next is hair, not mine, but Nikki's and my excellent 1500w inverter. This will allow the use of the hairdryer for Nikki to dry her hair. Obviously caning the batteries but with running the engine at the same time, offering a balancing act. Next stage would/could be to run the van electrics via the inverter and meaning I could actually use the microwave whilst running the engine as well.

    Another step would be to use actually good expensive batteries, this too would resolve some issues. As my research has led me to understand just how crap some of these batteries we are sold as leisure batteries really are.

    One thing for sure though, is I know people who do it, nether get a generator out the van and cook a pork pie as well. :RollEyes:

    However the great thing about a forum is a simple question get's met with Why on earth would you want to do that?

    so again, simple, I rarely if ever have hook up, I motorhome in -20 degrees without hook up for 2 weeks., I have a women with hair, kids with laptops and a hairy dog to look after, my requirements are different.

    Now I hope Im keeping it simple :Wink: in my explanation. :thumb:

    what haggers is thinking on fitting is a good piece of kit,it will allow the alternator to charge at upto 140 amps and monitor the chargeing and will charge a battery five times faster than the standard alternator and a whole lot faster than a genny or a 50amp charger:thumb:
    designed for boosting alternator output on boats:thumb:

    Hairdrying

    Hair drying is a perennial problem in a motorhome without hookup. The 12v hair dryers are pretty pathetic in output and tge mains one through an inverter uses a lot of battery power, however it's not as bad as it looks.
    Yes the hairdrier will draw 100A from the batteries, but it doesn't take long to dry hair. Assuming that hair can be dried in 6 minutes with a standard hairdyer on full blast (1200w) then the power drawn from the batteries is just 10Ah (used 6 minutes as makes the arithmetic easy but pretty reasonable). This would be replaced in a couple of hours with a 100w solar panel in good sun, or in not much over half an hour with my four panels.
    A microwave uses a similar amount of electricity but again is not used for hours on end, probably usually 15min or less.

    Have you considered the output of the van's alternator, nominally 65 or 70 amps. Have seen Sterling products on narrowboats and both they and the alternator can get pretty warm :Cool: when boosting flat leisure batts.

    But again, thank you for your help but your missing the point.

    I have an 80w solar panel already and TBH, in my situation is overrated and useless.

    If I camped in Spain like the rest of these people, fine, but we don't. The most I saw out of my solar panel was 2amps this weekend in Chester. Now bearing in mind that most of my time is spent camping in a British winter in the hills of Scotland, where sunlight becomes available between 9 and 4 that's 6 hours of solar charging. This in turn would equate (on this wkends figures) to 14 amps if I was very very lucky.
    Now, again, for you who sits in the van wearing a big thick jumper reading a book, that might be fine. For me, who has, 2 laptops running, heating running (blown air high drain) a TV and various other charging going on, Im knacked before I even think about drying hair.
    No amount of solar panels will solve my problem.


    The only solving is a Alternator to Battery charger and decent batteries.

    So can I please pretty please ask again.

    Has any one fitted one of these them self? is it a DIY job? I have seen the fitting instructions and they appear quite simple.
