Eric on Kimberlite is currently in Sint Maarten and will sail back to the US in 5 or 6 weeks.  

If anyone is interested by some of the parts I have left, this would be a good opportunity to save on shipping.

Bill, 

I am looking at doing this same project. The elbow out of the sea strainer, what challenges did you encounter with it and what size Nipple did you get to fit into there.. If you also had a size / part breakdown of the two manifold sections you made it would be a fantastic time saver!

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

Hello,

1. My brushless pump motors are a lot more efficient than the very basic brushed flowjet motors. Additional the frigoboat box applies PWM to the old brushed motor to convert 24 volts for a 12 volt pump, that adds even more unefficiency to the old system.

2. Reliability: brushless motors are used in places where reliability and 100% duty is required. Like atomic power plants, industry aso. With my conversion we get rid of most of the wear. At Scott we had to use a simple brushless motor because COVID-19 prevented us from shipping our new designed motors with advanved 100% duty marine bearings. 

3. For the boats using RAWwater for cooling, I created a pump version that flushes the tube system automaticaly to prevent silt. 

4. Scott measured 5 liter per minute at 25% motor speed. As the speed is free to adjust, the flowrate can be adjusted to the optimized rate. I run the pump at 30% and higher in flush mode. 

As we are going to convert an other Boat to the new system we will get more data about the energy savings. 

Kingd regards

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!

I asked my technical / warranty contact at Xylem but he couldn't answer because he was working at home. I'll try again as that was 6 months ago. 
 
The software associated with my brush less pump says it's running at 6000rpm but that must be an error. I can still read the text on the spinning motor body and I know my eyes aren't that good!

Re: Lithium Batteries under Consideration

Grant Starling
 

Dean,

Yes, both are 12v, I have a Santorin which runs a 12v system, I guess if you are running a 24v house bank that would complicate it some, but there is probably a solution out there.

Scott,

It is a lot of capacity but I converted the entire boat to electric, no gas, so we do have a larger capacity need as we are running a convection oven/microwave combo and 2 plate induction hobb, plus toaster, kettle etc etc.  I have a victory multiplus 3000w inverter charger running the show.  I will eventually have 800w solar on arch and hardtop and a decent wind generator which should mean little if any generator requirement.

Of course until I am actually out on anchor for an extended period I won’t know for sure.  But can add components as required to properly balance the system.  I took the decision to err on the side of caution capacity wise.

best
Grant

Thanks Dean,
I believe that battery balancers are essential.
We have 6v 210Ah batteries in three parallel strings of 4 in series.
Each string has its own balancer for 4 batteries which I bought on Alibaba for minimal cost.
The system works well.

Re: Lithium Batteries under Consideration

Scott SV Tengah
 

Grant, that's a LOT of capacity! Since you're talking about prop shaft alternators, do you have an older Amel that runs on 12v or are you talking 900amps at 24v? We have 450ah/24v and go through roughly 200-250ah a day while on anchor. In general, solar provides that and a bit more - that said I'm not in the UK or Scandinavia. :)  My math was always that if I add more capacity and didn't have enough renewables, it would just lengthen the period between when I had to run the genset. Are you "balanced" on renewables vs. capacity? 

FWIW - the Victron tech that I spent so much time talking to advised that if I was going to add more capacity, do it within the first six months as the batteries do age (despite marketing materials) and develop higher resistance and the new ones will absorb more charge, causing potential imbalance issues. This is one engineer's instruction so take it with a grain of salt, but I find it valuable because he was basically telling me NOT to purchase more of his company's products because I waited too long. So he hates his sales colleagues and/or he was telling me the truth.

It is an at sea foot rest for when you are sitting on the head. It slots into the grill on the floor. Adjust to your leg length. Henri thinks of every need.

Slavko,

if you sit on your throne you can position the foot rest by inserting it into the holes in the shower grate based on your height, in case you need when the boat is heeling.

Re: More battery questions

Dean,

Thanks I will order a pair. I checked the Lifeline technical data and general information and they say nothing about balancing. They do talk about not mixing old with new, but we all know that batteries age differently so it makes sense to balance.

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.

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

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.

These are foot rests that encourage one to be able to better brace
themselves when using the marine toilet.
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.
