Not necessarily. BMS size (measured in Amps) is determined by your maximum discharge and/or charge rates (measured in Amps), not cell capacity (measured in Amp-Hours). There are some scenarios where a larger BMS could be required, but others where it would not be necessary nor provide any...

I think there are two primary reasons for this: - Victron's primary market is not the United States (and the NEC is an American thing) - Victron's pimary markets are marine (and increasingly vehicle based) systems, not Residential/Commercial buildings / fixed structures where the NEC is more of...

The same is true for me (well not since the early 90's, but the first PC I built as a teenager, is the PC I am using today). Every component has been replaced at some point in time, with the exception of the case, which is a nice all aluminum design that could last pretty much indefinitely. I...

Sounds pricey, but also sounds like a pretty specific edge case that would be big time overkill for the vast majority of people. Under what conditions do you foresee needing 24,000W continuous?

Yeah where the DL button would normally be (top right), all i see is a message "No permission to buy ($30.00)" but that is possibly because I'm not a member of the xenforo forum.

Somewhat tedious, I agree, but at least its a one time thing. Maybe try it out with just a few of the subs you care about, see if it works for you, and if it does, spend the 5 to 15 minutes it would probably take go through them all. As to the extension you found, it looks useful for a forum...

How much do the victron charger and renogy inverter cost in total? You probably are not too far off from the cost of a decent inverter/charger. Victron Multiplus-ii or the original Multiplus would be a good option, but they are pricey.

Can you link to the specific BMS you are referencing I'm not sure where you are getting these numbers from but I don't think they are accurate. Ampacity of the wire depends on a number of factors, including the insulation temperature rating and ambient air temperature. My guess is that the...

I don't know if this is possible or not, but it would be a nice feature to have. If you'd like to research this feature independently, the forum software we use is called Xenforo, they have a support forum with lots of knowledgeable people. You could also see if the "news feed" or "watched...

Hi Gormur, welcome to the forum. Sounds like a cool project you are working on.

This is definitely a consideration as well.

Which is one reason to avoid buying from "a random Amazon company that sells Victron stuff" For better and worse, Victron's model is not the normal direct-to-consumer, made-for-mass-consumption Amazon/Ebay/Aliexpress model common these days. They prefer a network of knowledgeable, competent...

Lots of good info in your comment, but I just want to point out that many common 12V devices used in vehicle based systems can be found in 24V as well. DC compressor fridges, LED lighting, usb chargers, diesel heaters, and so on are available in 24V (one exception to this is the popular roof...

As others have mentioned an 'energy audit' or at least a rough tally of your largest expected energy consumers is a good first step, it'll help you wrap your head around the project and narrow down your options, and it'll help others help you (because without hard numbers it is difficult to give...

Some years down the road, that might change things as the industry adapts (I hope so at least), but as it stands right now my experience is there aren't as many 48V options in comparison to 12V or even 24V, and vehicles with non-12V charging systems are rare. Also since much of the equipment...

My guess is that any cost savings from smaller wiring would be offset by the added cost of the per device dc-dc converters, but I could be wrong. I suppose you could/should price out both (and take into consideration cost and availability of, BMS, overcurrent protection, etc which could tip the...

My 2c, a van is relatively small, and most van builds make heavy use of 12v or 24v appliances/devices. For these reasons, the upside to 48V will be a bit more limited and the downsides will be a bit more of a bother. Many of the popular brands and parts people use for vehicle and marine...

Is this question whether you *can* do this or whether you *should* do this? If can, than yes If should, than it depends. Also, don't forget about 24V, for many people, its a good compromise between the two. But it really depends on your goals and your system. Every standard voltage has its place.

Before you make a decision on your craigslist cells, you should know that Battery Hookup has a deal on CATL cells right now, they are from EV packs, apparently new/unused, and EV grade. Its worth looking into. You can either buy a whole pack (of 20 cells I believe) or in sets of 2 cells.

I suppose you would still need to clarify if: "can be used at 100% rated current" satisfies "continuous operation at 100 percent of its rating"

I'm not sure what the correct answer is but to me, the quoted bit from Midnite and the quoted bit from the NEC seem to be talking about two different things. This doesn't seem like it satisfies this: I read the midnite quote as simply saying the breakers can break the full rated load...

I don't know, personally I have the opposite impression. I see DIY batteries as possibly more attractive for a vehicle/camper build. Vehicle builds are inherently have more constrains and are space limited, DIY lets you tailor the build to the space available, and choose your components and your...

Merrell is the brand that works for me. I finally wore through a pair of zero-drop trail running shoes I liked on my last adventure. Really well made shoes that took a beating and then some.

Not exactly. EVE cells are more popular because they are more available to DIY'ers not because they are safer or more reliable. CATL is one of the largest LiFePO4 cell manufacturers in the world, but their market is mainly EV's and other large business customers, they don't officially sell to...

Thanks!

Funny enough, I was just looking into Starlink on the road last night. Thanks! I'm happy to be back and see some familiar names/faces (and apparently many many new ones)

I would not trust or recommend this company, They have a track record of disingenuous and misleading marketing, and outright unethical business practices--beyond even the "normal" misleading marketing rampant in this market. Based on the OP it sounds like they may have stopped some of this to a...

I believe I have read (and my recollection is very hazy), that the optimum is a shunt rated for more or less 1.5x your max expected current. There is another much smaller forum (google group I think) run by a person named Dacian, there is more technical discussion of shunt sizing on that forum...

I don't think it is actively updated/revised

Yes, but IIRC, the 11.8psi you arrived at is what at least 2 companies (EVE and A123 I believe) state as a target (12psi), and what a few people had already mostly deduced independently as best we could from the spec sheets of EVE and possibly others, as well as a video on the topic and A123...

Can you characterize more specifically what you mean by this (a few moderate cycles)? Full cycles, but low C-rate?

Especially If you see solicitation, self promotion, marketing. This applies to well known companies and companies Will advertises through his channel just as much unknown suppliers or overseas resellers. If you suspect an account of being a spam account or disingenuous (businesses posing as...

This is just good general troubleshooting advice. When a site won't load or loads wrong, before assuming its the site try on a different browser (or at least a "safe browsing" mode or separate profile with all extensions disabled) and ideally a separate device before assuming the problem is...

Creative and sounds tasty. Never heard of an almond flower biscuit though (but it also sounds tasty). Your recipe sounds like it was born out of the combination of hunger + limited ingredients I'm beginning to get a taste for kimchee, I like pickled/fermented stuff in general, but kimchee took...
