Wow. Great Intel Bill. Thank you 

Makes one rethink lithium in light of the insurance issues.   Or at least consider the firefly a greatly improved bridge to wait for insurers to figure out the low risk reality of lithium.

This is also the perfect time to actually measure the capacity of our batteries, and monitor their health since we are discharging them from 100% full to as close to 0% as you can get. For our battery bank we do this by turning on a 1000 Watt space heater, which pulls about 50 Amps out of our 480 Amp-hour battery bank draining them fully in a little under 10 hours.

 

For our 480 Amp-hour battery bank Firefly’s minimum recommended charger capacity is 96 Amps, and a maximum of 240 Amps, with an optimum target of 192 Amps.  Our DC generator puts out 150 Amps, and our shore power inverter/charger does 70 Amps.  

 

In Early October 2020 we installed our current set of Firefly batteries.  After installation, initial charging and testing we did a full ”restoration charge” bringing the batteries from 100% full, down to dead flat, and recharging at 200 Amps

 

Firefly’s current specification sheet for the G31 version of their batteries lists the C10 capacity as 448 Amp-hours.  Our first test in Oct 2020 came in at 454 Amp-hours. It seemed we were off to an excellent start.  Our batteries managed to supply about 1% above rated capacity.

 

In April 21 after 6 months of use, we again ran a full discharge test, and the result was 459 Amp-hours. Even better!  Obviously this was not a trend that could continue for long…

 

In Sep 21 after 10 months another test:  453 Amp-Hours.

 

Jan 22 at 15 months: 448 Amp Hours, right on the original rated nameplate capacity.

 

I do not have any feeling for how precise these numbers are.  Are they +/- 1% or 10%?  No idea.  The measurement is a bit dicey, since I certainly do not have laboratory grade control of the discharge rate.  So I can’t yet say if there is a real trend here or not.  But the (very!) good news for us is after 15 months of constant use our batteries test out right at the original manufacturer’s capacity specification, or a tiny bit better!

 

Considering that an inexpensive set of flooded lead acid batteries would be approaching the end of their useful life at this age, we count this as a total win.  Will these batteries last long enough to justify the additional cost?  Maybe.  Maybe not.  But they are certainly on the right track.

 

For the way we use our boat, the performance of these seems to be an excellent match.

Re: Fresh water tank pipe noise

I had that sound after the aft most water tank section on my 54 was cleaned. The copper pipe was pushed close to the vertical face of the tank by a monkey fisted boatyard worker during the cleaning process.

A little gentle bending got it far enough away that it doesn't touch anymore.

Re: Machining AMEL-specific tools in NZ (outhaul puller PLUS wrench for the rudder-post-packing nut)

Danny and Yvonne SIMMS
 

For the packing nut wrench how about get a piece of flat aluminum out of a engineers scrap bin and spend a  it of time with a cutting wheel on an angle grinder (or a hacksaw), finish it off with a file and sand paper. That's what I would do if my pipe wrench wasn't so effective.

Re: Bent pole hook

karkauai
 

Hi Eric.  It's the hook that hangs the outboard end of the whisker pole on the rail in preparation for deployment.  I posted a pic in my first post about it.

I really don't want to drill out the rivets , remove the outboard end fitting, and the line it is attached with.  Bending it in place is proving difficult, as it is very stiff and has a lot of curves.

I would go on shore to find a flat hard surface with a big hammer, a vice clamp and a torch to warm it if possible in order to try to unbend it.

David,
I cut the one I use out of 1/4-inch aluminum with a bandsaw. I used the nut as a template.
Attached is a photo , it is also in Bill's book. It took me about an hour to make , including a drill to make
The hole in the end of the handle. I used a grinder to smooth out the piece and a orbital sander to put the final finish on it.
Total time about one hour.

Re: Fresh water tank pipe noise

 

Ian, the first photo is of the aft-most section of the tank. The pickup line is copper and could possibly shake and knock against the wall, but I have to wonder what would cause that.

Is it possible that there is a slight suction-side air leak? A burst of air into the suction side might cause that, at least I think so. The other end of the copper pickup line in the photo is near the freshwater pump and a hose runs from the line to the pump. When Amel made your SM, they used some sort of sealant between the copper and the hose and 2 hose clamps to help avoid a suction side leak. There will be no evidence of a suction side leak and no water leaking out, just air going in. See the second photo.

Re: DOES ANYONE KNOW WHY THE EMAILS i POST TO THE GROUP DO NOT SHOW UP?

Hi David,

the message "poor reputation" is an information about the Spam Confidence Level(SCL) or SPAM reputation from a SPAM Scanner or e-mail server or best, an e-mail gateway.

Very small or old SPAM scanner use one or more databases from companies, that serve SPAM informations about e-mail addresses or domains on a blacklist.
On this databases, it´s mostly very "easy" to become a record on it.
Our group send some emails every day. And when then a user on an open e-mail provider (Hotmail, gmail and so on) mean, this is SPAM, it is possible, that he (or she) click on a button, that mark the e-mails as SPAM.
When this user or some more user do this sometimes, some of this e-mail provider generate a record to one of this database. And some e-mail provider generate this record automatically, when the systems recognize some e-mails with the some content for some users.

Better e-mail gateway's use this databases, too. And this systems are using some other tools, rules and algorithm, to set the SCL.
And on this complete work, the gateway generate a poor reputation and about this the SCL.

So what is to do?
Someone has to check, use your ISP only one off the databases from a SPAM blacklist. When this is correct, mostly there is a process, to delete the record from the blacklist.
Use your ISP a modern e-mail gateway with algorithm, sometimes it is possible, to generate a record on a whitelist.

Re: DOES ANYONE KNOW WHY THE EMAILS i POST TO THE GROUP DO NOT SHOW UP?

 

Groups.io is constantly working on an issue caused by users of groups.io. Some users either accidentally mark incoming messages as spam, but more often when they do not want to receive any more emails, simply mark it as spam. This included a few members of this group.

The Internet Community of ISPs is constantly trying to identify those people producing spam. Because a few users Groups.io make this error, this will happen. It is ALWAYS the smaller ISPs that do not update their database. Optonline is one of those ISPs. If you have GMAIL, you will not have this problem, unless you mark a Group email as spam.

I get an email from Groups.io whenever someone marks an email as spam. And Groups.io immediately removes that member from our Group, sending an email to the member with a link to re-join. BUT, please understand that the marking of that email as spam has already done its damage with regard to the ISP community trying to eliminate spammers. Almost every time this happens somebody at Groups.io is required to mitigate the issue with the ISP community.

I hope this is understandable, but if it is not understandable to you and you have accidentally marked an email from our Group as spam, please change your email provider to GMAIL.
