i've been working on Li Batteries for a few weeks since we're going to upgrade in spring 21.
for our SM, I have a narrow selection
the batteries from
Victron ,

or from a company Ripower in Germany that can build batteries on your desired dimensions! Price not much difference from standard batteries .

Over the decades with Amel, I sometimes sat in on part of the week long schooling each new Amel owner received as well as the somewhat shorter training I got on the three new ones I owned. The Amel guys always said to listen for the anti-siphon

"Clear it's throat" on start up and then 

" Mind it's manners" all the rest of the time.

A clever and catchy way to remember this important item.

Very important and astute observation. We do the same. Luckily we have little ladies who get paid for a weekly clean out of the salt water system. Also, first time I started the engine with Bill Rouse on board he reflexively pointed me to that siphon to look and listen to the stream in the starboard cockpit drain. Just yet another reason I’m so thankful we did the Amel school.

Hi all,

Over the few years we have owned Garulfo, we came to notice that the anti siphon vent for the engine that exits in the starboard cockpit drain hole was a good tell tale of a restriction in the raw water line: 

when everything is clear (intake thru hull, vetus strainer, transmission heat exchanger, impeller, etc), the stream of water out of the vent line into the drain is continuous and silent,

when the flow is restricted, the initial spurting of water and exhaust gaz continues to the point of becoming annoying and I know i need to go and clean something. After clearing the line, the flow is back to normal. 

Do other A54 owners share the same experience? Do my conclusions make sense, or is it some kind of coincidence?

Any feedback welcome!

Hi,

In the long run it is even more advisable to abandon the traditional car batterie style and take one 24 volt 400, 500 or 600Ah lithium batterie instead building it up from 12 or 24 volt sections. 

I would prefer a central based BMS controller supervising the hole batterie at once, not packages without com port where one cell does not know what the other does. 

And you should look at the guaranteed capacity. Means this battleborn has only 90% capacity, according to their discharge graph. In my eyes thats a hint for low quality? 

A good quality batterie, with good chemistry inside, will guarantee 100 to 108% capacity.

There is no "drop in batterie" that is misleading because in the end you need to setup all the electronics, chargers, BMS aso. to lithium. That is the real change. Not in what plastic case the cells are packed.

Using 24 volt units makes sure you will balance cells across 24 volts instead of 2 x 12 volt leaving a potential unbalance between the two 12 volt banks.
For capacity the answer is simple, as much as you wallet can last. You will always find ways to spend the available capacity in the end, so more is better. 

For your chargers you will need to investigate if you can set them to the exact same charging parameters. That may be difficult.
Also think about your charging regime. Again Battle Born was not very explicit about this but if you boat is connected to shore power for extended periods, you should lower your float voltage to reduce the state of charge to 70-80%. This can be difficult to achieve if you have several charge sources as this means adjusting it very precisely, up to tenths of volts accurate.
I did not like the way Battle Born played down this issue but Lithium batteries do not like to be kept at 100% charge level for extended periods. Even Tesla has extended logic in their battery management to handle this issue. So when Battle Born claims it has superior cells that do not suffer from this problem, I’m skeptical.

Just my 2 cents....

Bill,

 

Is this a piece of foam – about 2-3” -  attached with a tie to the cable? It’s hard to tell.

 

Thanks.

I will soon be replacing the Antenna (main mast), cables and VHF. I plan to thread the new cable from the top of the mast attaching it to the old cable while it is removed. If I can, I would like to keep the foam. I think I could add this as the new cable is being inserted but it is unclear how the foam is attached.

 

 

With best regards,

Yes, and you should cut the altinator  so that batteries are not always loaded in full during a long drive
