Re: Converting my Amel 54 to lithium batteries: what I did, what I like and what I don't like (after one year of full time live aboard use)

Scott SV Tengah
 

Good timing on your question. I have figured out a way to have the Victron BMS control the Mastervolt Reg-on wire. I purchased this solid state relay at the suggestion of Peter Kennedy (PKYS):

https://www.mouser.com/ProductDetail/Crydom/DC60S3?qs=mNyg5qXQ%2FsdpD8JEee%252BrpQ%3D%3D&gclid=EAIaIQobChMIsruU14Da4AIVEo_ICh1PFARyEAYYBSABEgIUS_D_BwE

It is very low current draw so the Victron BMS successfully triggers it. However, as a solid state relay, there's around a 1 volt drop across the relay! So I ended up up adding two more Hella relays. Excuse my layman's explanation but this is how it works:

1) The Crydom solid state relay coils are triggered by the Victron BMS. As you may recall, the Victron BMS sends a voltage-high on the charge disconnect wire (a bit less than battery voltage) when all is good and then goes open circuit when there's a problem and charging needs to be stopped.

So I have this charge disconnect trigger the solid state relay. 

2) Because the reg-on wire is also the alternator voltage sense wire, the 1 volt drop across the Crydom relay isn't acceptable. So the load circuit (is that the right term? I'm talking about what is passed through when the Crydom relay is closed) controls a 24v Hella relay's coils. The 24v Hella relay connects battery positive to the reg-on of the Mastervolt. So when the BMS is happy, this 24v relay provides the battery voltage to the reg-on wire, which turns on the Alpha Pro and allows the alternator to charge but also provides the voltage sense to the regulator. We'll call this Relay2

3) However, I didn't want that 24v hella relay triggered 99.999% of the time, which it would be because 99.999% of the time, the Victron BMS charge disconnect "all is ok" signal would activate the Crydom relay and consequently activate the 24v Hella relay. So, to solve this problem, I added a 12v relay that is controlled by the Volvo ignition. We'll call this Relay3.  It's easy to get that because the original Amel setup has a 12v relay there already, so I just spliced off that. When the ignition is on, the 12v relay closes and pass through 24v, which is used to power Relay2. In that way, Relay2 is only energized/activated when the ignition switch is on.

I hope this makes some sense and perhaps if you do understand it, you could make an electrical diagram that explains it to others in a simple way.

Note: The Crydom's terminals are exposed, as you can see. I put liquid electrical tape over the whole thing to protect it. Your ELK-924 relay seems to be a good solution too. I didn't see a voltage drop across the relay, so maybe that allows you to get rid of what I call Relay2. However, I think the Crydom is bi-stable and I believe it draws little to no current when activated. Not sure about your proposed relay.

I noticed you don't have an external BMS. I suppose the Battle Born batteries have an internal BMS that disconnects the battery when it detects overly high or overly low voltage? My understanding is that if your chargers (alternator/solar/multiplus) can get damaged if they are outputting a lot of current and you suddenly disconnect the battery. The way the Victron VE.BUS BMS charge disconnect works is that it tells the chargers to stop charging. Seems the Battle Born system just disconnects the batteries and does nothing to turn off the chargers? Maybe that is ok, but you will need to investigate.

New Improvements

I have installed two simple switches to control my Victron Quattro. Pretty sure you can do the same with the Multiplus

1) The first switch is to turn the charging portion of the Quattro on/off. I run the VE-Config software and added an assistant called "charge current control". The switch simply passes through 24v that I got near the autopilot above the galley sink and goes to an Aux Input 1 on the Quattro. The charge current control assistant then dictates what happens. When the switch is activated, the Quattro charges at 120amps. When it is inactivated, it doesn't charge. This allows me to easily turn off this big load to assist with warm up and cool down of the generator. 
2) The second switch turns the inverter portion on/off. There's a remote switch input built into the Quattro. I measured Quattro inverter's idle consumption to be 40watts! That's nearly 40 amp hours a day! So now we just turn the inverter on when we need it. Sure, you can get the $125v Victron control panel to do this, but I find this simpler, cheaper and it doesn't consume energy.


Keeping state of charge low when I leave the boat for extended periods

I think I figured out a way to keep the battery in the healthy SOC range for lithium batteries when I am away from the boat for extended periods. Keep in mind I have 960w of solar, but you can easily apply the same solution if you're just plugged in. When we left the boat over the summer for a month, the batteries sat at 100% for a month in hot Southern Virginia. Not good for the batteries.

When I leave the boat, I will use the BMV-712's built-in bi-stable relay to turn on the inverter (using the remote switch wiring I mentioned above). I have a 220v AC (200w) dehumidifier that will be plugged in. When the BMV-712 hits 65% SOC, it will close the relay. That will turn on the inverter and the humidifier will start running and drawing down the SOC. The relay will stay closed until the battery SOC gets down to 45% and then the relay will open, which then will turn off the inverter. 

I think by using this method, I'll keep the batteries in their optimal 45-65% SOC range and also have the dehumidifier run daily. Win-win. I don't recall you having solar, but you could probably achieve something similar with shore power. Just remember to dial down down your charge current on the Multiplus, otherwise the dehumidifier could never draw down the SOC otherwise.

Generator Start-Stop and "load disconnect"

There's a way to have the BMV-712 trigger the Quattro's programmable relays to start/stop the Onan. I have started to think it through but haven't implemented it yet. I am thinking of having the generator automatically start when the SOC drops below 30%. See the 'Alternatives Using Assistants' by Thierry Cortasa below.

https://www.victronenergy.com/live/auto-generator-start-stop:start

Two differences in my plan:

1) Rather than have voltage trigger the start/stop, I will use the BMV-712 bi-stable built in relay to do that. The output of the BMV-712 relay will go to the Quattro's Aux Input 2. Then I will use the Quattro programmable relay assistants perform the start/stop. I am thinking of having the generator automatically start when the SOC drops below 30% and run the generator until SOC reaches 75%. Note that I can't have this active when I leave the boat for extended periods and setup the BMV-712 to turn on/off the inverter, as described above, since the BMV-712 only has one programmable relay.
2) Another improvement I will make is that I will have the Quattro "Ignore AC" for 30 seconds upon the 30% lower SOC generator startup threshold, to allow the oil to circulate before imposing the huge charging loads. I will do the same when the SOC hits 75% to allow the generator to cool down a bit. 

I have been struggling with the load disconnect and have decided I will not add it. Here's my nightmare scenario: I am sailing at night in 45 knots and focusing intently on keeping us safe. The batteries are severely imbalanced somehow and even at 35% overall state of charge, there is one cell that has dropped below the voltage threshold and triggers the BMS to disconnect the load. At this point, I would lose navigation, autopilot, everything electrical. It's an unlikely scenario, but it could happen and the results could be very unpleasant.

To solve this, I will add the load disconnect as an additional trigger to start the generator. If the Victron BMS load disconnect signal is triggered (aka goes open circuit), it will start the generator and charge the batteries to remove that low cell voltage condition. I think this is far preferable to simply disconnecting all electrical devices because it actually solves the cell low voltage problem.

So the generator start/stop will be triggered by either SOC or the BMS sending a "load disconnect" signal. I just need to figure out a way to make sure I can connect both the BMS load disconnect wire and the BMV-712 relay output to the same Aux Input 2 on the Quattro without causing any trouble. Also need to think it through to ensure that if the BMS triggers a generator start, the BMV-712 relay will still turn off the generator when it hits 75%. Just need to test I guess. Thoughts?

Some thoughts/comments on your choices specifically:

- You will need the Mastervolt Masterbus-USB interface to adjust the charging profile in your alternator. Or just borrow one.
- One advantage of using 12v batteries in serial to create our 24v house bank system is that if you have a problem with the engine/genset battery, you can easily borrow one from the house bank. You won't be able to do that with your 24v Battle Born batteries. That said, one huge annoyance of my system using 12v batteries in serial to create 24v is that, annually, I need to disconnect by batteries and charge them individually to balance them out. The cells in a 12v individual battery will balance automatically but two 12v batteries in serial to make 24v will not balance themselves. 

Maybe a solution for you is to get a backup 12v starter battery that is connected a battery tender that keeps it topped off whenever you run your generator. That way, you have a backup that stays fully charged in case the single engine/genset starting battery fails in the middle of nowhere.

- Your idea of being able to charge and invert simultaneously is good. I was considering doing that by having my Skylla charge and then my Quattro invert to avoid the 50hz/60hz problem you describe. But frankly, we are going through the P-Canal soon and I think most our cruising route will be in 50hz land and in any event, we're rarely at marinas. In Panama/Colombia I got 230v/60hz power, which my appliances don't love. So what I simply did was turn off the 230v outlets and appliances, run the charger for an hour or two to charge the lithiums and then disconnect shore power. That's good enough for us at the moment. Your solution is obviously preferable if you're going to be spending lots of time in 230v/60hz marinas. 

Hope this helps you and everyone else. I welcome comments/criticisms/improvements.

Re: Size of main anchor for Super Maramu

Arnold Mente
 

Hi everyone,
I am now following the discussion about the anchor and the type for a few days. I have had the following anchor types in my 35 years of sailing. CQR, Delta, Bügel and Rocna. I currently have the Rocna 33 kg on my SM. I also drove it on my Benetau 523. I think the discussion is going in the wrong direction. The connection between anchor and chain length and chain dimension is not considered. On a sailing yacht for all areas should be 100 - 120m. The chain length is essential for the horizontal forces on a well buried anchor. Only this interaction is essential for the holding force. You can also use 100 kg anchors and they will break out if there is not enough chain.

I was not going to interject into the anchor conversation, as this topic is akin to religion.
The Mantus is of the latest designs in anchors. Very good. I worry a bit about the original style, in that it depends on the tensile strength of the four bolts holding it together. This is a worry. In addition, there is a frequency of bent shanks. The shank is thinner than competing anchors, and doesn’t tolerate a bending load very well. 
Mantus fixed these issues with their new design anchor. Check it out.

With a sandy bottom most anchors work very well the question is how do they perform when you’re forced to anchor in either San Luis coral or heavily grass bottoms to me and Achor that would improve by chance of getting a good stick in those conditions using proper anchoring technique would be a valuable asset

Re: A54 fridge circulation pump

Oliver Henrichsen, SV Vela Nautica
 

Hello, 

My pump is based on a brushless motor, not a stepper motor. 

You asked me about building an "adapter" from old fridge system to VESC conrolled brushless pump. 

My adapter replaces the original controll box. 

It has the following features:

1. If any fridge freezer signals cooling needs, it activates the VESC brushless pump.

2. Rpm can be regulated from 0 to 100%

3. Pump can be stopped by switch

4. LED display of operation. Flash every 10 sec in standby. 
Flasch every sec when pump is active. 

5. Energy consumption. In standby some mycro uA. In operation about   15 mA.

6. Connections
- 24 Volt
- serial port VESC
- signal wires coming from fridges freezers

As I understand, you ordered the VESC and the brushless motor yourself? 

Please contact me by my email, I like to send you a Video how the Pump is setup.

Re: Sailing performance Mango vs Super Maramu

Excellent Rob. 
I only looked at Maramu and Mango.  Really liked the extra room on the Mango but ended up with an older Maramu; mainly cost factors = just do it!

We have looked into a maramu, mango and supermaramu before deciding on a mango.

The mango is comparable to a maramu, but slightly larger.

The difference between a mango and super maramu depends, since later mango’s can also have electrical furling and the bowthruster.

Aside from that, the mango has a regular propshaft (which I find an advantage) and a different hullshape, especially aft. Systems are 12v. Prices of Mango’s are more favorable. 

In general many features of the mango are also present in the super maramu. 

More details can be found in sailboatdata.com. 

Good luck with the choice, either way all boats are Amels,

Hello,

I am on the market for Amel. Have seen Mango and Super Maramu. At first I was very much into Mango but after inspecting Super Maramu I am more into SM now. I would very much appreciate any insight about the differences of two boats. Like sailing perfomance, systems....

Re: Sailing performance Mango vs Super Maramu

We have looked into a maramu, mango and supermaramu before deciding on a mango.

The mango is comparable to a maramu, but slightly larger.

The difference between a mango and super maramu depends, since later mango’s can also have electrical furling and the bowthruster.

Aside from that, the mango has a regular propshaft (which I find an advantage) and a different hullshape, especially aft. Systems are 12v. Prices of Mango’s are more favorable.

Re: A54 fridge circulation pump

Mark & Debbie Mueller
 

Hope the new pump works out, it would be nice to find a substitute for the Flojet.  When you get it installed if you have a question about the flow due to the head pressure measure the discharge rate where it exits the hull and see if the volume is adequate.  Good luck.

Re: Converting my Amel 54 to lithium batteries: what I did, what I like and what I don't like (after one year of full time live aboard use)

Jamie Wendell
 

Hello Scott, I realize your posting was from awhile ago, but I am getting ready to convert my Amel 54 (Phantom) to LifePO4 batteries. I have read your "dissertation" with great interest and am interested in getting an update from you before I make the plunge.
Have you been able to resolve all of the "problems" you noted? By the way, here is what I am planning to install with my electrical contractor:
 
(12) 24-Volt (50 AH) Battle Born LIFePo4 Batteries
(2) Victron Multiplus 24/3000/70-16
(2) Victron Smart BT Dongle
(1) MK3-USB Adapter
(1) Mastervolt Alpha III Regulator
(1) Victron BMV-712 Smart Meter w/Temp Sensor

Since I already have a 3kVA inverter, I did not want to upgrade to a Quattro or a higher capacity Muliplus unit. That would have forced me to do a lot of wire upgrades, and I think 3kVA will suit my needs. With the lithiums, however, I have decided to split my AC bus into 2 columns - 1 side for inverter-capable and the other for high-current loads, such as my 230V(only) watermaker, dive compressor, and saloon AC. We decided on 2 inverter/chargers for redundancy, where one unit will be set up for charge only. That way I can charge and invert simultaneously, and even provide 50hz power when connected to 60hz shore power in the US. I intend to use the existing battery charger circuits to feed the Multiplus units, so as to maintain the flexibility Amel provided originally. The incoming shore/generator ATS will remain as is.

I also have at least one possible solution for you regarding some of the "problems" you indicated you still had to resolve. Maybe you have already found the solution, but I have used the following Elk Products relay very successfully, and I'll bet it will work for your Mastervolt reg disconnect. This is what I intend to use.

ELK-924

The ELK-924 Sensitive Relay module features DPDT (Form "C") dry contacts for general purpose switching of devices or high current loads. It operates on 12 or 24 volts DC and can be triggered with a negative or positive input at an incredible low current of only 1 milliamp. Also available in a 4 pack (ELK-9244) which is packaged as 4 relay modules grouped on a pre-scored break-off circuit board.

Hope all is well with you.

Lewmar winch intermittent switching

ERIC LICHTY & ROBYN ATKINSON
 

Regarding past thread on Lewmar winch switching, we had same problem here in wet, wet Pacific Northwest.  Opened passageway access to control boxes and stbd winch motor and observed quite a bit of condensation on all.
Put a space heater up there and ventilated with hot air for 20 minutes and got normal operation with winch and all switches......go figure......

Hello Ruedi,

I’ll try that. Thus far I’ve used diluted HCL to achieve some success. Rinsed thoroughly after a short time

Re: Sailing performance Mango vs Super Maramu

I was unaware Amel made a houseboat...
The Mango is older and a model enhanced became SM. 
Someone who has sailed extensively on both should be able to describe the nuances of each.  
Cheers Slavko!

Seems odd that Amel would not use a flush latch,the pics show what looks like a pain in toe.

Bill, categorically and assuredly, those lock downs were installed by a beaver with bad teeth. JP is always so full of crap and leads folks down his errant path. I cannot afford to piss him and his support group off so I leave it alone but I can tell you, absolutely that Amel did not install those lock downs. Justification # 1, why have key locks inside a boat with a locked companionway? Need I say more?  Everyone named JP is an *** ****.

JP, Ken, et al

None of the other hundred or more SMs that I have been aboard had PERKO latches. Perco is a Florida company. If anyone is interested in the latches shown in the photos that were added to this SM, here is the contact information:
Perko Inc.

I am not sure where in Europe Amel sourced the latches that Amel optionally installed on SMs. Regarding the installation of floor latches/locks, I have always believed that having the floor hatches locked in case of a roll inverting the boat would be the least of my worries. That said, BeBe SM 387 had Amel installed latches and they were not Perko.
