Turbo question

Rob Hughes
 



This is my 6 yr old turbo from Volvo tamd22 after being cleaned. I have a loss of rpm only able to get 2200. Is this rust color normal? I'm wondering about all the pitting. I have a new turbo on order. Just want to see if I have another issue that needs addressing. And if anyone has pictures of their turbo after cleaning could you share that please.

Arno,

My Victron BMS reports cell level voltage down to 0.01v. I can view it via bluetooth and have seen it vary by 0.01v.  I can attest that when I had an imbalance, up to 90% SOC, the cells had the exact same voltage, down to 0.01v. Above that, the variance reared its ugly head. This is not theory - this is my experience living with this system fulltime for 2 years. So I would be very skeptical of any active balancer that has the same resolution as you may be unknowingly exacerbating an imbalance by relying on marketing promises.

If I haven't stated before, I do agree that if you want a system that requires no planning and very little monitoring aside from making sure you don't go below 50% SOC, then lead batteries are fine. If I were in your position and spent most of my time plugged into marinas, I would probably NOT get lithium even if someone paid me to take it. 

One guy may have had his gel batteries last 9 years, but longevity is not the main reason we got lithium. As we speak, I am running the dishwasher and washing machine and the admiral just turned on the microwave - all on battery/inverter. The continuous draw is around 160amps and the voltage is quite stable. Because of the huge boost in charge efficiency compared to lead, I won't be running the genset to recharge the batteries, either. Our solar is more than enough.

But as economists like to say - there is no free lunch. Lithium requires planning and thinking prior to implementation and if you plan it right, it is set it and forget it. I am not quite there but moving in that direction slowly. The same thing applies if you compare roller electric in-mast furling vs. manual stacking mainsails. The former requires some thinking but, at least to me, is well worth the effort. For my use case, lithium is the same. 

I hope my contribution to this forum is useful in that those who are off-grid and would rather not run the genset all the time are given some useful info that they can use to plan their systems. It is beyond my risk tolerance to try to assemble battery cells and rely on them in the middle of the ocean, so I went with a mostly-one-brand solution that allows me to monitor every single of the 24 cells via bluetooth and if a cell fails, quickly remove that battery pair and continue on with my trip. Luckily I haven't had to do that yet.

Hi Scott,

Typically good BMS-es can measure at 0.01 resolution. So even at lower SOC you will be able to see differences. Charging up to 100% can be postponed longer with continuous balancing. Active balancing means you are using the charge of the fuller cell to charge the less full cell. That improves the speed of balancing and prevents useless heat generation.
Obviously it's not as world of difference all together but if you design a BMS for lithium you may as well make it top notch. The system is expensive enough to push it to the limits of longevity.
Your battery-monitor has a easier life with lithium as the charge/discharge losses are far less so it will keep an accurate reading longer, especially if you can set the Peukert value yourself.

If you are less concerned about those things than I think the Battle Born 24V batteries are a good choice, just do not expect 10-15 years of life. If you do achieve 10-15 years you can always celebrate at that time, but at least you will not be disappointed.
As said before and as said by others as well; there is still so much development in this area that I prefer to wait a few years to see what the next best will be. I just read something about a person managing 9 years on some Gel batteries so it's not that all other chemistries are useless.

After market engine mounts ? #replacement

Paul Guenette
 

Hello,

I am looking at replacing the engine mounts on my 2004 Yanmar 4JH3-HTE engine.

The current Yanmar mounts, (on the fuel and oil filter side), are labeled 200 which I believe would mean they are Yanmar part number  YAN 129670-08351.

There are other companies like R & D  and Poly Flex that make after market  engine mounts.

Have any of you tried any of the aftermarket engine mounts ?

If so, what has your experience been ?

Thank you.

Mine has the magnetic switches, instead of the pushbutton stop switches, and importantly, they are ‘normally closed’ switches, that open when the thruster is in the required position.

Does anyone understand "continuous cell balancing", because I don't?

When I have had unbalanced batteries, the batteries are look perfectly balanced until you get to 90% + SOC. This is because of the flat voltage curve of lifepo4. Above that, the imbalances show up. How does an active balancer reliably detect an imbalance continuously when things look perfect below 90%? Through coulomb counting to determine amps out to see if the imbalance shows up during discharge? That wouldn't be reliable as cells age at different rates. 

Note that imbalanced batteries generally just reduce your total capacity until the imbalance is corrected. This is because if one of the 4 cells in the battery see an overvoltage condition, the BMS should stop charging altogether, even though the other cells could still accept more charge. Charging is restarted once the overvoltage cell drops below the high voltage threshold, either through a resistor to draw charge from it or a method to transfer that excess voltage to the other cells. Then the charging resumes. The charging will start and stop multiple times as during the cell balancing process. I have seem this before on my Victron setup and have been assured by Victron techs and my own research that it is totally normal.

The desire for active cell balancing seems a bit misplaced. Even if somehow they detect cell imbalances when there is no voltage difference, you still need to fully charge once in a while to reset the battery monitor as I believe all battery monitors use (amps in - amps out) to determine SOC and as batteries age, that needs to be recalibrated if you want any sort of accuracy. So solving the former problem still leaves the latter.

Hi Bill,

So the GRP cover was always there. I took it off and bedded it back with silicone. The odd thing is that the front end was left open for spay to go straight in.

I think that this mast furler should be pulled apart more often to avoid the aluminium seizing in place, maybe every two years, just drop it, move the shaft up and down, check the gear box and lip seal. Alternatively have a stainless shaft made.

Fortunately I had a spare gear box on board as one was in very poor shape with bad corrosion on the aluminium. However all went well and both are back and fully functional with new shaft seals. Although I now do not have a spare aboard. Something that I would like to have if I go off the beaten track.

I decided to make a cover out of some PVC I had kicking around to protect the boom furling one from the elements, as shown in the pictures. There is a drain hole at the bottom of the GRP cover in case some water gets in. It is quite small maybe 8mm. It could be widened to say 12mm if required.

Has anyone tried this? If so was it a success or does it just deprive the gear box of ventilation?

Hi Paul,

This Best Lithium BMS still uses passive balancing and it does not say if it only does top-balancing. So from that perspective it's not a great BMS.

(UTC+00:00) UTC

Where:
Internet ZOOM

Organizer: Bill Rouse brouse@... +18323804970

An RSVP is requested. Click here to RSVP

Description:

Jimmy Cornell has influenced the contemporary cruising scene more than any other sailor. An accomplished sailor, public speaker and author, he has sailed over 200,000 miles in all oceans of the world including three circumnavigations as well as voyages to Antarctica and the Northwest Passage.

Thousands of sailors have fulfilled their dream of blue water cruising with the help of Jimmy Cornell’s books, among them the international bestseller World Cruising Routes. Now in its 8th edition, and with over 200,000 copies sold to date, this is one of the best selling nautical publications in the world.

As the founder of the highly successful ARC transatlantic rally, Jimmy Cornell is credited with having devised the offshore cruising rally concept. In the last four decades, Jimmy Cornell has organized 38 transatlantic rallies, five round the world rallies, and one round the world race, with over 3,000 boats and 15,000 sailors having participated in his sailing events.

From my perspective, the first Jimmy Cornell seminar that Judy and I attended was after we had sailed most of the world and had over 20 years of sailing experience. We learned a lot!

We are very pleased that Jimmy has taken time out of his very busy schedule to give a special ZOOM presentation to the Amel Yacht Owners Group. I encourage you to RSVP soon for this meeting.

hi Porter it does come off but lots of prying and force and lube.  I still had to buy a new one as it could not be repaired in grenada.  I believe in the south Pacific they are more creative so good luck.

Subject: [AmelYachtOwners] Canvassing for ideas: removing motor housing A54 “MAT” foiling motor.

Dear Amelians: 
I beg any insight if you would. This is a 1.5 year old motor and housing from Amel for the main sail foil furling motor.  The last one, seal was damaged and the whole unit unsalvageable. This is a “new” 1.5 year old replacement. Now not working. Relays and switches all fine. Motor gotten progressively more “tired”  and now has stopped rotating. 

I have removed the base and look in and see no corrosion. But I think I need to remove the whole motor assembly from the housing which mean also removing the top cap. The bottom cap slipped off with mild to moderate traction. The black top cap will neither rotate with respect to the white housing nor slide out from it. 

Aggressive traction I think will bend the bolts. I’ll get more aggressive if I know the top cap comes off the housing. Does it?  There are screws I removed that seem to indicate the cap would pop off/out. 

Tapping on base of motor: I’ve done gentle tapping. No movement. Might I damage motor by more aggressive tapping?

Of course I can disconnect and take off the boat and to town to search for a technician, but it would be so much easier to sort it here in the boat. 

Some photos below illustrate the situation. 

Many thanks in advance.
