    As you have not got a definitive response yet, I will try to illuminate using logic and theory.

     

    As the current from an alternator rises, the charging voltage goes down, and the Orion will limit the current I presume to protect the alternator from overheating. This means that until something stops the charge to the lithiums, it will just look like a discharged battery to the alternator, so the charging voltage from the alternator will not be 14V+, I suspect maybe 13.8 ish, but that will be a guess, and it will depend on how the Orion is set for maximum charging current.

     

    When the Orion or BMS stops charging the lithiums, the LA will be controlling the current it will accept, just like all LA batteries, so as it approaches fully charged the current will drop. The smaller the LA battery capacity, the faster it will approach fully charged and further limit the current.

     

    I can't work out where Peter got his 100Ah from, I can't see why your 50Ah one would not work. I would like an explanation as to how Peter arrived an 100Ah. Afterall, 70 amp were common on cars in the 90s that had 50Ah ish batteries with no ill effect (I know Ah should be CCA).

     

     

    LA batteries are only half there rated capacity,  I watch my Orion when it's charging and the amp meter showing amps into my starter battery from which the Orton takes its power. My large battery seems to cope well with charging the Lifepo4s which are roughly 700ah, I see the Amps flowing out steadily through the DC2DC and the alternator coping well. Previously I had a 100ah starter battery of unknown age which didn't cope with the DC2DC very well  I often saw the LA battery taking the lions share of the alternator output leaving not much for the Lifepo4s, now this could have been a duff starter battery however it was still working OK. Its just personal experience but the 240ah battery is working far better than the original

    Is that what it is for?

     

    I thought it was a Battery to Battery (B2B) device. Does it actually have an alternator protection role? 

     

     

    You can set it up to do various things, although the Orion limits its output at 50 Amps protecting the alternator from self destruction

    Just bumping this so hopefully someone knows the answer:

     

    Does it matter what type of size of LA battery is used between the alternator and B2B charger to protect the alternator? 

     

    Could I just use a 50ah sealed start battery for example, or should it be a bigger leisure or dual use battery?

     

    My alternator is 70A and the battery bank is 560ah. I've bought the Victron Orion XS 50A DC-DC charger.

    As I said I am using a 240ah battery in my system, it's the starter and bow thruster battery so it needs to be big. I think you will need something in the 100 amp range to make it work right. Like me you have solar so should get return from that even in winter

    Sorry I didn't see this. They're just standard belts I think. I'm sure I could change to a bigger alternator but I don't really need one as the engine isn't my primary charging method and if I'm moving the boat more than a few hours then the 70A alternator is all I need, the batteries are always fully charged by the time I moor up.

    I used a 240ah leasure / starter battery because its what I had works great

    My mate seemed to do Ok I once helped him deliver a desk from Cumbria to Wolverhampton it cost £12,000 and that was without the chair I forget what he charged for that.

    Anthony M made a table for an ex, I supplied the lump of oak and he did the rest. I had the trunk for a few years on the moorings it was planned to be converted to logs but Sue convinced me it would look better in her place, it did look lovely when finished, however we fell out and went our separate ways. Next time I saw it after she died was very sad, it was still beautiful as Sue had been, but the charm was lost on me at that moment, she was only 52 sudden heart attack took her.

    Asleep on our boat!   A good way to go but it gave us a few problems not to mention 3 police officers and 3 "undertakers" all on board at the same time.

    Thank you but if you have got to go what better way than tucked up in bed on a boat.  (particularly for an ex-naval rating as he often called himself.)

    There are worse ways to leave this life, asleep in your boat sounds good to me

    This BBC article discusses this and some other points: Should you feed garden birds? - BBC Future

    This is the published paper that it refers to: Killing with kindness: Does widespread generalised provisioning of wildlife help or hinder biodiversity conservation efforts? - ScienceDirect,

    Plus this one, albeit not a UK based study: Frontiers | Urban Bird Feeders Dominated by a Few Species and Individuals

     

    It's by no means a certainty, but I do find it quite a compelling argument.

    I love feeding the birds and the swans etc, yes sometimes it's a pain when they come knocking at the door for breakfast at 6.30 but that's part of the joys of boatlife

    You are back on your old hobby horse of solar panels.

     

    A couple of points.

     

    1.  I seem to remember way back when (soon after I joined) you were boasting about a friend/relation who was making more from a small area of his farm than the rest of the farm.  (apologies if it wasn't you).  Yu can't blame farmers from doing what they are urged to do - diversify into a money making venture.

     

    2.  You keep harping on about the land not feeding us.  You are ignoring the facts that it has been proven crops can be grown below solar panels and that panels can be raised to allow this.  You will trot out the point that the panels aren't raised.  So what they can be if/when it is considered necessary and knowing farmers the chance to make even more money from the field will encourage the changes.

     

    I agree on wildlife habitat however there are far greater habitat threats than solar farm.

    Better place exist to put solar panels, most buildings in the UK don't have them.  It's my mate Mick Longford that has 6 wind turbines on his land virtually no production lost. To get that same production all the farm would have to be covered in solar, solar in fields is pointless on buildings brilliant

    How do you think swans and indeed all wildfowl survived a couple of centuries ago when winters were a lot harder and people hadn't spare money/food to feed wildlife?

     

    They would have moved as conditions worsened.  Now because of changing climate and knowing there is a source of food i.e. humans who feed them they don't.

     

    Not good.

    I agree we are destroying wildlife habitats allover the world, I bang on about it all the time, currently there are plans to put solar panels over 17000 acres of panels un Norfolk, mostly prime agricultural land. How do birds like swans land there to feed? They can't equally that land isn't feeding us which is a total disaster in our changing climate we cannot rely on other countries for food production

    The idle so and so's they just needed to head to the nearest grass to graze away happily.   I hope you don't feed them bread as it is thought to cause angel wing.

    No grass we had snow and ice up to six inches of it

    Have to say that I'm kind of puzzled as to why these swans were on the ice in the first place. They clearly weren't sitting in the water when it froze because even they have more sense than that, and having stepped or flown down onto the canal after it had frozen they could just as easily have stepped or flown back off it again once they'd realised it was solid. As you say it isn't a surface that they are comfortable with so perhaps they should have got off it before any boat came along.

    It was all frozen, so they were staying where they knew they would be fed, we all feed the swans, so they do the rounds knocking on boats for food

    Peterboat did you find out where the Rother boat had to go in a hurry?

    and whether or not it were a necessary journey or a jolly?

     

     

     

     

    It was going up the flight to try and Dam the river for lock repairs, given the locks were frozen it does seem pointless. Another day or two and the ice has thawed. It's planned repairs and has been sitting in Rotherham for a while it could have gone up before Christmas.

    Swans like humans can do things that hurt if they really feel the need.

    But in this case running on ice for them is impossible no traction for them, they can hardly walk never mind run! If the imbeciles on the boat had 2 brain cell between them they would have seen that wouldn't they?

  14. 1 minute ago, Jerra said:

    Clearly they were wrong.  There is a video back up the thread showing a Mute Swan taking off on a road.  I will agree it can/will hurt their feet but that doesn't prevent them taking off.

     

    I would also agree capture and release at the nearest water would be preferable, providing of course the water is large enough to give the 30 yard run up to takeoff that is required..

    Wind in right direction and panic might do it, I walked one back to the water the other month in Rotherham, clearly lost, it was like herding cats!

  15. 23 minutes ago, Wanderer Vagabond said:

    From personal experience I can confirm that they are able to if forced. A number of years ago I came across a swan waddling down the middle of Shaldon Bridge in Devon holding up the traffic. In a moment of 'brilliance' I came up behind it and with one hand on it's neck and the other arm around it, picked it up. That was the moment I realised "You haven't really thought this through, have you?". I either had a 250 metre walk with the swan under my arm to get off the bridge or heave him over the parapet. I opted for the latter and for those who have seen the film 'Dumbo' the outcome was very similar. The swan plummeted down towards the river and at the last moment spread it wings and gracefully flew off up the River Teign and out of sight, to my immense relief. :unsure:

    Yorkshire Swan rescue told me that swans can't take off from roads  apparently its too painful on their feet. They land on roads because if wet they looked like water. I have with a police inspector captured a Swan using his coat. After that it was easy I walked down the stairs and released him in the canal.

    ????????????

    Not you and the ice was a large thick sheet of ice that was pushed under his boat and lifted up.

  16. 1 hour ago, magnetman said:

    That does sound bad. Ice should be broken into dozens of small pieces when a Boat is passing through. 

    I wish it had been, Alan's boat next to me wouldn't have been lifted out-of the water.

  17. Just now, magnetman said:

    None of my Boats will get sunk by ice. 

     

    I suppose it is relevant to discuss the ice. It would be better if there were craft specifically designed to break ice so yes one could argue that a Boat which is the wrong shape at the front will cause a different outcome. 

     

    A lot of work Boats could fall into the category of inappropriate shape. 

     

    An icebreaker does  not smash the ice by pushing it. The idea is to rise on top and use gravity. 

     

    So yes, thinking about it, breaking ice with certain types of commercial vessels could be viewed as inappropriate. 

     

    We would need to see pictures. 

     

    It's a 15 foot wide pusher tug, it's all but flat, it was pushing big sheets of ice in front of it, unfortunately as it made progress it got faster

    I would think that breaking up surface ice would be a good thing for waterfowl.

    With them in it with 30 sheets of thick ice going in all directions? If they had left it another day it would have all but melted it's so warm 

    6 minutes ago, magnetman said:

     

    I reckon a thinner sheet of ice slid towards the Boat is more dangerous. Its like a blade situation. 

     

    Smaller surface area. Also thicker ice tends to break into smaller pieces if a Boat is going through it. 

     

     

     

    If you think about it thin ice means melting at the margins. So there is more opportunity for the ice sheet to move across the water as it is pushed away by a Boat.  This increases the impact force and also because it is thin you will get the slicing effect. 

     

    It will be the thin ice which sinks the Boats not the thick ice. 

    Thick ice is thin at the edges. 

    What amazes me is if this had been your boat and it had been sunk by there actions would you have Been happy? Most certainly the people filming the swans trying to escape wernt happy and thebpeople on the boats which had their recently applied blacking removed were definitely unhappy! But does that matter when for a thousand pounds they can book dry docks to repair the damage

    Last time I saw a swan, it had both a pair of legs, and ditto of wings.

    They can' hardly walk on ice and can't take off from ice Esther, just like they can't take off from roads. Water or grass only

    I'm amazed nobody has made any jokes yet about Uranus.

     

    Anyway, nowt wrong with with a bit of ice breaking by people that have got somewhere to be.

    However another day would have seen it a lot thinner and less damage done to boats, given where they are going the locks would be frozen as well, fast flowing water requiring unfastening 1 pan at avtimevto pass through lockshard work given the cut was frozen there as well

  20. 25 minutes ago, Stilllearning said:

    I used to cruise quite often in icy condition, fringe thun stuff to thick enough to need a run up sometimes. No body ever complained, in fact I got thanks from some of the moorers for breaking up the ice, so they could move. I suggest the OP needs to be a bit less woke.

    When thebice lifts a boat out of water complaining is justified plus the swans had nowhere to go from these thick sheets of ice! Killing those I suspectbis against the law

    I take it they’re off to try and Dam the river at Tinsley lock 12 for the gate replacement? Supposed to be finished 14th March, must be the worst time of the year to try and Dam a river like the flood prone Don and replace river lock gates. But it’s a civil engineering company thats doing it I hear, not CaRT, so must know what they’re doing🤔

    They probably gave up leaving them at Eastwood on the CaRT Commercial mooring for a few days as no space, as they’ve been occupied by encamped Contineous Cruisers sorry Contineous Moorers the last 2 years plus😂👍

     

    They left them at AMA, trouble is offroader delivers there, of course if CRT clearing the continuous moored off the commercial moorings at Eastwood would help as you say. Water levels are projected to rise rapidly on the Don so they will be lucky methinks to Dam the Don there?

    Oh dear, I've always considered OP to be a reasonable geezer. 
    Perhaps he's having a bad day, we all get them.

    The boat concerned Uranus had to reverse of and ram the ice it was so thick at the turn point it kept on doing this, in reality there was no point the locks further up are frozen solid as well, it had 2 pans and a digger On a another pan at the front. It goes into a river section which is in the red so if something goes wrong it's in the weir for them. All seems pointless as in a couple of days the ice will be gone. Whilst our section of navigation is commercial at Rotherham Town lock it it was at one point a remainer waterway don't know if that has changed? Picture of ice below it was in a trailer and is over 3 inch thick same as the ice in the cut

    Is the Tanker running this week?

     That will definitely shift the ice and anything stuck in it❄️❄️

    The Tanker declined to run to avoid damaging boats as the ice was that thick!

    A commercial boat operating on a commercial waterway, seems fair enough to me.

     

    How is a boat being lifted out of water damaging to it?

    It was a large slab of thick ice that rammed into its side and slid under the boat lifting it out of the water. It was totally unacceptable really as the flight no doubt will be iced up as well I think its going up there to do work. It had to drop its pans off the ram its way through the ice, the first boat was only blacked last year looks like its wants doing again

    The plastic boat owners as they should have protected/removed their boat before the frost I expect will be the answer

    Shouldn't have to is the answer as there isn't room in the boatyard to put them there

    Ice in the canal? 

     

    In January?

     

    No-one could have forecast THAT and taken appropriate precautions to protect their boat, could they?!! 

     

     

    How?

  24. Today a Rothens workboat Uranus fought its way through ice on our moorings, the ice is over 2 inches thick and caused havoc with swans, ducks and boats as it pushed them out of the way! I phoned both CRT and Rotherns which got me nowhere! The ice lifted the plastic cruiser out of the water so I think it counts as potentially damaging to move! I know they have to get on with things but these are our boats and if one had sunk who would have been to blame?
