Brucey, You may have hit on something. I seem to recall that "total network power" field, and long ago "stopped seeing it." Tomorrow I'll drill down and see if it's there. That almost gets the answer, if it's there. Thanks!

Several comments: 1) The posts about flipping are bogus. Cats basically only flip when they have too much sail up. They can also, I guess, flip in extreme seas (think Cat 1 hurricane at least) -- where your propulsion would be laughable. This isn't a place you'll ever be. And cats the size...

Parallel batteries with parallel BMS makes for a real coordination problem. When one battery is full, it should call for shutdown of charge systems -- but if other batteries are still charging you don't want to shut it down. This is especially true of the alternator -- if any one battery is...

My cells came from 18650batterystore, which seemed to be a reputable supplier. I've now learned that they don't have the dots, and they don't have the helicoil inserts (and yes, I partially stripped one hole using a torque wrench -- I've now bought longer screws for these terminals with more...

I am about to pull the trigger on EVE cells, about 300Ah each (not sure if 280 or 314 or something in between) for my sailboat. My current battery is 740Ah of AGM, and works wonderfully -- this would indicate that I should go with 8 cells (2P4S) for a significant step up in available power...

kromc5, Nice work! A question. You have some pics showing complete systems using the single stud style terminals, and the start of a system using the twin hole style. I can get my cells in either style -- do you have any thoughts on the differences? I note that you only used 1 hole of the...

It's not a safety concern. I shattered a rigid panel on our boat, and while the glass rained down for weeks (months?), none of the pieces were sharp and none were over the size of a peanut. So, it is potentially a financial risk (who wants to buy a new panel!), but no safety risk. But, on the...

I think your thoughts are theoretically correct, and in a high-C use, maybe significant. In my case, my load on 3P 300A cells will be 95% 5 to 30A (or .1C if one cell picked up ALL the load), max normal load about 100A for under 20 minutes, and theortical max load of about 200A (toaster AND...

OK, I'm screwed. 12 cells in a 3P4S. Putting my last cable on. All the cells nicely connected with bus bars, no issue. Final cable (a big honking 4/0 only 8" long) put a bit of leverage on the terminals, and broke off not only the one it was screwed to, but the bus bar took the next one with...

That brings up something I've been wondering about. On sailboats, with salt water, we use a lot of aluminum, and then stick in SS fasteners. It is a disaster, an adhesion suitable for space age connections. I've been wondering about SS fasteners in those terminals, but thinking maybe inside...

I'm learning the limits of my knowledge here, thanks! I've been using VictronConnect for a couple of years. Not very much, as I get almost everything I need, faster and easier, from my LINK2000, but still on a regular occasion. And you've pointed out two things I wanted, "it's in there."...

That makes sense. I only have 1kW of solar (if you count the 200W of useless Solbians at rated value, not the 30W they make today...) and barely 600Ah (7kWh) of LFP, on a boat that doesn't get 100 days of use a year. It's definitely "play around" territory, and the Victron big buck integrated...

In theory, you could add a dedicated data page to the Cerbo that gave those three things, but I'd think they would be much more useful on the engine control panel. On my boat, with a diesel, I have mechanical meters that show RPM, Motor Temp, and Oil Pressure, and I look at them often when...

The battery terminals are aluminum. That all by itself validates using aluminum as a bus bar. But damn, being on a sailboat, it is so hard to accept that idea! It's not a scientifically explainable thing -- it's pure gut. LOL. NoOxId Special A should solve any issues with corrosion on the...

Amazon can help with fasteners! M6x30 delivered in no time flat: https://a.co/d/iRKaYhV Or 20mm in pretty colors: https://a.co/d/5etPjuy I think those colors are only anodizing, which is just aluminum oxide with dye added. So they are essentially "just aluminum." but if you want studs to top...

I bought a Finirsi HRM-10 resistance tester to hopefully help with my new LFP setup, or at least to provide insight. It tested cells very well, providing consistent/repeatable readings on each cell (and showing that the cells were very close). I am not posting a link, as I am not crystal clear...

Brucey, You are 100% correct. It unfortunately provides the data in Watts, and my brain works on Amps, but it still provides the aggregate power. (The summary page shows W for each MPPT as well, so maybe Victron has a preference for Watts). Thanks!

* I actually have the SmartSolar. Ooops... So weird that "BlueSolar" is not the one with bluetooth..... * My LINK2000 is at my navigation station, monitors both my house and start battery, is on 24/7 and can be seen walking past. Perfect for seeing SOC. This one display gives SOC (actually...

I have a sailboat, and am about to upgrade the existing panels (an accident has shattered my existing, so a chance to redesign). A simple replacement with identical panels will get me about 600W. I'd like to get over that. For starters, consider money to not be an issue (of course it is, but...

I have a tendency to want something, and think that the world wants the same thing. It's clear that I'm the only person who thinks that a more consolidated VictronConnect screen (summing all MPPT, for instance) would be nice. Most prefer a Pi solution hardwired to the individual components...

I'm leaning heavily toward making my own, as nothing ready-made is suitable. I do worry about the rigid bus bars tying 6 cells together, but it doesn't seem to provide real-world disasters that discussions over a beer would indicate. 4S3P is a bit tempting for various reasons, bus bars being...

I realize this is a fairly old thread. But it is very close to my question, and the best I can find on the forum. Rather than starting a new, nearly identical thread, I'll post here. I'm preparing to do a 3P4S build of 304Ah Eve with the new 2xM6 studs. Bus bars in general, and especially...

I have a 43' sailboat, currently with 800Ah of AGM. Over the last 3 summers, I've been aware that they aren't long for this world. Yesterday, I used a heat gun with the inverter, and in under 5 min I had a "low voltage alarm" -- and my batteries were at 100% SOC when I started. Not sure the...

I should reiterate that my bank will be built as if it were all 12 cells. 4 cells will be blocks of wood. In fact, the layout is such that it will be two on each side of the assembly, so the "blocks" don't need to be precision. The bus bars will be built to support the full bank. Wire sizes...

I'm not sure I see a value in this for me -- but I do get that it turns a 4-cell pack into an easily managed unit. In my case, I'll have a solid box with close tolerances -- once installed, the cells won't move. BUT, I have a suggestion. In my case (and in your "real world" assembly), I am...

This would address the ability of the solar panel itself to be supported, and may work. But it still leaves the solar array unsupported -- the end of my structural arch is only 26" from the forward end of the solar panels (and consists of two tubes only about 8" apart). There is a welded 1"...

Well, I decided to dig in and see. I only have the MP here now, so I can't test the BP until later this month when I have one to play with. But I played with the MP (hey, the worst that can happen is my 2 year old 3kW inverter smokes, right?). Here's what I learned. - Both the Charge Enable...

The Cerbo can certainly handle the MPPT. Unfortunately, Victron doesn't make a BMS (what they sell is an enhancement to their battery -- it's more like a VMS (Victron Management System) and is incompatible with any other battery or DIY project. It's a serious omission in their ecosystem. Some...

So another thought on this. I can get those flexible bars to maybe be acceptable. I only have a couple points where they are underrated, and I might be able to address that. So then the next question is how to tap into these cells for 400A? If I build the bars myself, I can take a nice spot...

I'm getting close to building an LFP pack for my boat. It will be either 2P4S or 3P4S, using EVE cells around 280Ah. Either studs, or if I get them from 18650 then the two hole version (which I like). Especially for the 3P version, bus bars are a challenge! I'll be fusing the battery with a...

I'm trying to settle on a BMS. My power needs are fairly high, potentially over 300A both charge and discharge. Also, since it is going on a boat, I have to be aware of ABYC (building code for boats) requirements. Also, since it's on a boat, I have space and power constraints. So, that said...

I have just received a dozen EVE MB31 from 18650. Well packed, look good, fingers crossed. I also have a FNIRSI HRM-10 resistance tester. I've tested all cells, and now don't know what to think of the data. Looking for advice! The meter on resistance would dance around, I recorded high and...

I just bought two of these for my project -- still in execution, so no real world experience yet My 4/0 lugs fit fine. And Peter Kennedy has great prices and great service. My understanding (I hope I'm right!) is that these can be remotely controlled, both on and off, by my BMS. However, a...

I was very wrong, and you are right. There are basically no trips over 100NM. In fact, Indigo is currently in the US Virgin Islands, with range restrictions similar to your plans. Indigo did make some comments in a post about timing weather to get east, as the trade winds hurt him more than...

This is my suspicion as well. It may be one of those things we realize is theoretically possible, and then make designing it out a "at all costs" kind of thing -- even though it never actually happens. I'm not terribly worried about them getting out of line vertically. Newton mostly takes...

They sort of help. If I stack bus bars on bus bars, sometimes 3 deep, I can make it work. Unfortunately, their 400A rating is more than a little optimistic. They are about 1" x 1/8" (I say about, because they are 2mm thick and1/8 is 3mm), and at 400A a 1" x 1/8" copper bar will be 65C over...

Docan does have great prices. I'm confused on the MB31 cells (314Ah). 18650 has the new 2-hole terminals, Docan has the 6mm studs. Why the difference, and does it matter?

Well, the marketing is handled by their marketing team....LOL It's 50' long, and it has a 50kW/67hp motor, which is quite reasonable (many EP boats massively undersize their motors). It reaches 8.5 kts, and I believe it. The battery (75kWh) can run the motor (50kW) for 1.5 hours at full speed...

Already new questions! For my space, an ideal arrangement would be 3 wide sets, one after another (3P4S), which would put 3 terminals side by side. Then each "interconnect" would be 3 connections wide (12 holes) and 2 deep (from first set of cells to second). This would in a theoretical world...

Just a follow up on 18650. I sent them an email on Sunday morning, and here it is Wednesday evening. The email wasn't antagonistic or mean, basically "here's what happened, what are my options." I'd have been thrilled with a "sorry, we are shipping two more." I'd have been happy with "we can...

Not sure if this is the right subforum, but it seems right. I have a simple (ha!) system, consisting of 4 BlueSolar, a 3kVA Multiplus, a SmartDongle, and a Battery Protect. My BMS (ElectroDacus) is not Victron-friendly (at least out of the box -- apparently it's not terribly hard to make it...

I figured I'd go ahead and take a pic. It's not a "torque wrench" issue -- I went and finally bought a torque screwdriver just for this project. The screws were all in an torqued, and then I was wrestling the 4/0 cable into place and levered the terminal off. I'd already pulled all the bolts...

Thanks for the input. A few questions/comments. * Making the holes is likely to be easy/fun. I have just come into access to a numerically controlled mill. So I can drill precisely spaced holes! * The bus bars that come with the cells would be very good for tying the cells end to end, as...

If somehow the BMS fails, and that failure somehow disconnects the battery (strange failure mode...it is more likely that a BMS failure would allow a fault condition to run unchecked), then I would need to manually override the battery switch to reconnect. Obviously, that solution requires...

Thanks, I think. Another protocol! I do have N2K, but not sure I have anything that would use the data -- although it opens lots of possibilities. But seems to require a Cerbo as the comms converter since my existing stuff only speaks VE.Direct, VE.Smart, and VE.Bus. I need to start a cheat...

I asked this on the Victron community, and the silence is deafening. I hope it is better here. I have a Mutliplus and a BP in my new LFP install. The BMS (ElectroDacus) has a single opto output for "allow to charge." I need to have this turn off the Multi and the BP. Both have "allow to...

We may be slightly misunderstanding here. When I said "stacked" I'm not talking about increasing capacity (ie, doubling up). I'm talking about the fact that I need a single bus-bar to run 6 cells long, and they only make them up to 4. To get to 6, I'd need to run a 4 cell bar, and then mount...

I'm an engineer so I have a mind that ponders. Doesn't make me any smarter (especially since I'm a Mechanical Engineer), just predisposes me to think. It's a curse.... So here's my thought. At Float, all the cells are seeing float voltage. If the old ones have the same float voltage (we...
