It is for you to put your feet on when the boat is heeled over and you need to sit on a toilet.

It anchors in the wooden floor grid.

Indeed, both the foot rests and the water tank gauge impressed me so much when I first viewed an Amel that I figured that a lot of other things were equally clever and well engineered. And that has been the case.

They fit into the teak grate over the shower sump.
Anecdotal rumor suggests Captain Amel was launched from the throne into the hanging locker opposite to starboard by an unexpected lurch and then crafted these foot rests...

Re: Rolls Batteries

Ulrich Michael Dangelmeyer
 

Dear all!

just my small contribution to the endless battery discussion:
after 10 months we came back to Soleil Bleu in September and all batteries were completely dead. None of them had more than 7 volts. Although the years before our 800 watt solar panels always kept them fresh. But after 7 years these lead acid boxes were obviously at the end. May be our marina people have been manoeuvring too much with the bow thruster in spring to steer the boat into the travel lift for servicing. Without power supply.

Then I asked Amel, they recommended a replacement with AGM 110 Ah, preferably from Victron, also they match perfectly into the batt compartment and with the installed setup.
We then immediately ordered 12 Victron AGMs from our marina, at a very fair price and not more expensive than from Germany and by freight forwarder. The batteries were there after 3 days by ship from Athens. No tinkering and experiments necessary.
The MasterVolt charger was adjusted accordingly and everything works perfectly. We are now back in Germany until spring, in the meantime the batteries are supplied by the solar panels. I am also considering whether to install one or two additional battery balancers. I follow Nick and Dean. I will ask Victron / TransWatt here in Germany for expertise.
Lithium batteries were not an issue for us at the moment, the boat was completely without power and the marina people were kind enough to help us with spare batteries for a few days. Lithium is only interesting for us in the next generation.

Cheers and stay safe and well.

Slavko,
I researched Rolls batteries last year and my choice was the S12-128 model, but this was driven partly by the fact that they are drop-in replacements for my existing Zenith AGM's.  Rolls batteries seem to have a good reputation.

I did not find them to be cheap, but also not particularly expensive, in the UK they are about GBP240 each.

Re: Rolls Batteries

Dean,

I was looking at S12-116 AGM. This is what I can get here. Price is 413 euro, and S12-128 are 438 euro. I am not sure if 12-128 would go in to battery compartment on SM 2000. I need to measure, mainly the hight that 240mm comparable to 233mm of 12-116. Will have t go to the boat in next few days :)).
They are definitely cheaper in UK. I need to put some pressure on Rolls dealer here :)).

Re: More battery questions

Dean Gillies
 

Nick,

I would recommend balancers as I have personal experience of AGM getting unbalanced, and I believe this should be avoided. Especially since the balancer is cheap. 

Victron suggest their balancer can be used for up to 3x 200Ah strings (pairs), so I would suggest you use two balancers.  You should connect the midpoints of two strings together and use the balancer on two strings.  Do this twice for your 4 strings.

I will be doing something similar with my 6 strings if my replacement batteries end up being AGM.

Rolls Batteries

Slavko Despotovic
 

Sorry to add some more about batteries. Previous owner replaced batteries 10 years ago with Victron AGM . So far I did not have any problems but I know from my previous boat that they much overdue for replacement. On my 2003 40th foot  I was replacing batteries every 5-7 years. Sailing 3-6 months per year and consuming 120-160Ah at 12V per day.
I am not ready for lithium as this is my first year of Amel ownership so I would go for AGM or GEL batteries. At first the Victron was a choice but then I found Rolls battery AGM with very high numbers of cycles. So, my question is strait-forward, What is the experience with Rolls 105Ah batteries, and as they very expensive for AGM, are they worth the price.

Thank you.

More battery questions

ngtnewington Newington
 

Sorry to go on about batteries……

I have 8 Lifeline AGM batteries set up as four pairs of 24v. So the four pairs are in parallel. I set them up as I found the original and as Amel must have set them up. That is I have not installed a battery balancer.  

At the moment I am on the boat half time so the batteries end up being 100% charged for weeks and months on end from the solar system which will hopefully balance them up. 

Given the cost of a balancer from Victron  energy of about $100 and the value of the battery bank I should install one.

Does anyone have an opinion on this and know if I only need one balancer or should I buy two?

Kind regards

Re: Lithium Batteries under Consideration

Scott,
I would definitely agree that changing from Lithium to Lead is highly unlikely, for anyone.  I started this comparative investigation because I'm impressed by the Lithium system which came with my new "Covid" caravan. I'd be happy with similar characteristics in my Amel.

Grant,
Interesting concept. Are both your engine and start batteries are operating at the same voltage?

Re: Lithium Batteries under Consideration

Dean (Scott),

I did a full upgrade to lithium about a year ago and am now adding to my battery capacity which is currently 400AH with another 500AH in preparation for world cruising next year.  

Lots of good advice given in the previous posts, and I would support much of what Scott has said about the challenge of designing a ‘system’ with lithium.  Any idea of a ‘drop-in’ replacement lithium battery should be treated with caution for the reasons outlined previously.

if I can add anything to the debate it would be the use of a DC battery to battery charger (may have missed this?).  I use a Sterling B2B 60amp charger between both my 90amp engine alternator and my 90amp prop shaft alternator and my lithium bank.  This allows all my alternator charging into my lithium bank to be done via a programmed lithium profile provided on the B2B60. 

As the alternators are both linked first to my engine starter battery (Optima red top), then through the B2B to my lithium bank, they cannot (easily) overcharge my lithium bank, preventing battery BMS from disconnecting due to high current.  This system also prevents the alternators from being destroyed from a voltage spike due to BMS disconnect.  As a fail safe I can also turn off the B2B manually to stop it sending charge to my lithium bank if I feel the need I.e. I don’t like floating my lithium batteries for long so if I am on motor for an extended period I simply switch the B2B off using the remote panel at my nav station.

This setup has worked well for me so far, so check it out if you are interested.

best

Re: New Thread on A54 fridge pumps (ATTN: OLIVER Vela Nautica)

Scott SV Tengah
 

Second update: I measured the pump flow rate on the original flojet with a hose and bucket and it was 6.5 liters per minute. 

I measured the flow rate on the brushless set at 25% duty cycle and it was a bit over 5 liters per minute. That lower flow rate probably explains some, but not all of the 60% energy savings I am seeing vs. the brushed motor.

Frigoboat literature states that you need to supply 3.8 liters per minute, so even at my lower flow rate, I'm well over the requirement.

What is really odd is that the fridges seem to run better in that they're running less and use less energy. I surmise there may be some truth in Craig Briggs explanation about how warmer water results in more efficient compressor operation. My freezer, which gets cooling water that has been warmed by the first and second fridges, seems to be drawing less energy. Overall, I have a daily power surplus that is greater than the water pump energy savings (with solar output accounted for) can explain.

So far so good. Now let's see if it lasts!

Re: Lithium Batteries under Consideration

Scott SV Tengah
 

Dean,

At least with my batteries, they are passively balanced. Most are. That means they don't balance between cells (even if I had a 12v system because recall that a 12v battery is 4 lifepo4 cells in series) unless you get them to 95% SOC or more. Only then do the "voltage knees" start showing up - before that, there is very little difference in voltage. Even when I had imbalanced batteries, the cells were perfectly matched up to 90%. At 95%, that's when the voltage spike became apparent and the balancing starts kicking in. I can't see how you would notice imbalance otherwise due to the voltage vs SOC curve of lithium. 

As you apply current, which will be reduced as SOC approaches 100%, that's when balancing occurs. This is all per my lengthy conversations with the Victron techs. That's how "automatic recovery" happens. Now in my 24v system with pairs of 12v in series, if you start with an imbalance between the two 12v batteries in series, the imbalance can get worse and may not be corrected. Same problem as in lead batteries. I just connect via bluetooth to my batteries whenever I'm approaching 100% SOC to verify that series pairs are balanced. FWIW - Victron advises against using battery balancers in systems such as mine where 12v are put in series to make 24v and then paralleled. I'm not sure why?

With regards to temp, my system doesn't have a "bank temp sensor" nor does Victron recommend one. High temp disconnect means that the BMS tells the chargers to stop charging when even one of the 24 total cells gets too hot per each cell's internal temp sensor. Note that charging is simply stopped - the battery is still connected.

The Mastervolt Alpha Pro 1,2,3 is controlled by a "reg-on" wire. That's how I have it safely stop charging if the BMS senses something awry. It required two Hella relays and a solid state relay - I wrote it about it in another post. I also installed a switch inline to turn off the alternator during long motoring sessions when I don't want to keep the batteries at 90%+. Very easy to do.

I honestly think if you're not living full time liveaboard, often away from shore power and you're willing to use the generator a lot, lithium does NOT make sense. It's a lot of brain damage and cost to get it right. It works for people with my use case and people like Garulfo (A54 with Mastervolt lifepo4 system for much longer than my 2 years) who when I asked him if his lazarette 230v breaker is working, he shrugged his shoulders and said, "I can't remember the last time I plugged in, so not sure." Not to put words in his mouth, but I'm pretty sure for him, he would never go back to lead.

Re: Lithium Batteries under Consideration

Dean Gillies
 

Hi Alan,
Thanks for your contribution to the pro-AGM argument.

We've chatted about the benefits of battery balancing before and we are in full agreement about its value in a series-string based system. You may recall I had one series pair of AGM's which had become unbalanced about two years ago. I tried to recover them by individual charging and I was planning to install a balancer in early 2019, but 2019 was a busy season and I didn't get around to it, and I've been unable to return to the boat since then. On detailed testing before I left the boat in late 2019 almost all of my batteries were very low on capacity.  I don't know whether there is a causal link between the unbalance and the whole bank degrading.  I inherited the bank from the previous owner, and I know it was installed in 2015, but obviously I don't know what use/abuse the bank may have been exposed to before I bought in 2017.  This experience colours my thinking about the longevity of AGM batteries on the Amel boats, hence my expectation of 5 years.  My previous cruising boats have all had less complex DC systems, none employing 24V, but (lead-based) battery replacement every 5 years was not unusual.  Maybe it can be better, but I have not personally experienced that.

If I decide to stay with lead batteries for another cycle, I will definitely install the Victron balancer. At the moment I have 12x 12V AGM's organised as 6 strings with no interconnecting midpoints.  My plan would be to introduce interconnecting midpoints to create two independent strings of 3 + 3 parallel connected batteries.  This way I can use two balancers rather than needing six of them, whilst staying within the Victron recommendation that each balancer is able to balance 3x 200Ah pairs.

I like your idea of the alternator switch. I do have a 3-stage external regulator that changes from bulk charging to absorption mode at 28.5V, BUT it then holds 28.5 for a minimum 4 hours before changing to float at 26.5. Not the best if you are starting off fully-charged, but better than an alternator that sticks at 28.8V ALL DAY regardless !

It is an endless discussion as you say.  Given the Benefit/Cost differential I think my decision will be either "Evangelical" (Go Lithium) or "Logical" (Stay Lead) :-)

All the best
Dean
