They're purported to be the dogs danglies in terms of spilt charge and essential for Euro 5 & Euro 6 regen alternator braking vessels.
I don't think it can beat a dedicated alternator. It definitely can't beat linked twins.
It may provide good charging, but at what cost?  If you assume it's 70% efficient stepping up the battery voltage, that means the input current is ~50% more (I think)
That makes a (2nd) alternator direct to battery a better bet as it will have less mechanical load on the belt for the same charge power via the B2B

Scruff.... I think I love you :-o


I'm forever telling people not to bother with split charge relays or battery to battery chargers and to fit a big solenoid between their batteries instead, set to power up when the engine runs   (easier on older stuff when you can wire to alternator warning light circuit)   they're only doing low power stuff in hobby use camper vans or work vans with an extra battery to power some lights

and I'm forever being shot down for saying that :-(

 Grin Grin Grin,
       Sorry Scruff, You are too late. I done away with directy drivey and went 4rib belt and pulleys, Got a decent result.
   Then went key start Lifan 6.5 horse  with lovely sweet Beemer 180amp alt...Oooooooo.. Eeee |Ba Gum you will have bother knocking the socks of this baby Scruff.
     It runs Grinders on full power ticking over, starts with a little half pull under load and when I am cutting steel with it, It does not even break a sweat on quarter revs.
 Alt is N47, so its really good and 2kw would be no bother to it. It has twin internal fans. I am thinking of moving out to the shed and sleeping next to it. but it is dam,d windy tonight.
                                 Biff
  Err Forgot to add, I will be fitting it with the Ghass conversion kit. It is supposed to be the cleanest of all bar RE.

Oh Scruff, That brings me back to my school days,
                        We had serious competitions as to who could pee the farthest up the wall. However it is not the kind of competition one can hold now in our senior years..(crikeee look what i wrote)
   I have a pair Symmetra RMs that belt out 4.5kw each and a 2 ton forklift Bank that would have a lot of difficult finding it way to your baffroom. They are rather static you know.
  I am wary, You probably have challenged half of the electricians forum to electrical duels and won every time. I am a mere Novice who just happened to turn up on my day off.

 Scruff,
   There is no doubt about it, You are my long lost cousin.
 I can tell by the way that you fix everything into the limited space. I just knew that I had an Identical twin cousin  somewhere  doing great things..
  If you need help to put it running correctly , well you know,, I AM ALWAYS HERE,, , You know of course  I am clueless about things that spark and shock but I can provide a great round of applause when you conquer it.
