I used to make wiring looms using rows of small nails on a real size shadow board as per the wiring diagram technical drawing, it allows you to lay the wires inside and split them off and test before lacing up with lacing cord. I used to keep a copy model for all goods we manufactured. You can buy rubber numbered sleeves which would definitely assist in BMS wiring.
I saw the pipe problem when the copper crimp system came out. A contractor has workers that could not solder, do the job. They could not layout the pipe neatly either.
Morning Ray, IM building my Seplos battery DIY kits, however they did not come with thin sheets of foam to go between the cells. I was hoping you could recommend a foam type used for this type of application? I have seen other use foam to fit between the batteries, but no one mentions the type of foam it is. I am sorry to see you have stopped your videos. I enjoyed your presentation style. Have a good day Ray!
Good morning, I use thin flexible material designed for use as cutting boards. I purchased mine on Amazon from a company called arrow home products. You can cut two out of each sheet and they come ten to a package. I intend to make more videos pretty soon. I’ve gotten extremely busy with other activities but the time to continue is drawing close. Good luck with your project!
Hi Ray. I have this BMS but can’t find a working copy of the seplos battery management software for my PC. Would you mind sharing where you downloaded the software as thee is no mention in the manual? Thanks
Ray thank you so much for all the effort and knowledge that you share with us,you explain everything in a way that even i can understand it I am in the fase that i am almost ready to build a off grid system in the Philippines and must look for a lot of stuff online bcse here is almost nothing to find But i have a question here about these sensing,balance wires What size is this and does this fit for other BMS to?any recommendations for the quality that we need or not… Also the ring size that you use on the end of the wires Thanks for the time that you spend for testing and make it so easy for us
The most boring video that I have made is the one about preparing the BMS wires to be used with the Seplos BMS. It is very tedious to watch, but I think it contains all the information that you need to answer your questions in a better way than I can do here. if you watch that video and still have questions, I will be happy to answer them. I want to make sure that you get the information that you need but right now I have to go out and cut trees from the ice storm damage. I’m hoping to also make a couple of videos today to post on the channel. Busy times.
Hi. I bought a battery queen vertical 14,4 kWh Battery from Deligreen with a Seplos V2 BMS with bluetooth. But it stays on standyby. It won't charge at all! Is it possible to gett screen shots of the right settings or maybe a anydesk session where somebody of the forum would check all the setting with me? It's so frustrating when it doesn't want to start. Can you help?
I bought two 200 amp BMS on minerals store at aliexpress store. They'll go through the flashing light sequence at start up when I first turn on power. The LCD screen lights up Seplos name, then everything goes black. I can turn the breaker off let it sit for a while to discharge and come back and it will go through the same sequence. Do you know what the problem might be? I should be able to use this without a laptop and the battery monitor software? I think I'll stick with JK from now on. 2A balance instead of 150 mA on these and most of the others I have. My daly's are junk.
Each battery gets its own BMS. The batteries are connected to a common bus. One BMS becomes the primary. It communicates with the inverter. The other two BMS are connected to the primary BMS and are controlled by it.
Interesting monologue about the loss of expertise with the conversion of craft to the assembly line as Ray demonstrates the BMS wiring harness assembly.
Hi Ray, I am thinking about going with the 200 Amp JBD BMS that Docan has in stock to ship with their cells, do you know how this one compares to the Seplos BMS? Also I am looking for an inverter that it can communicate with and the LV6548 or SP6548 don't list either BMS brand as being compatible. Is it necessary for them to communicate or what are the benefits? If it is necessary do you know what inverters support Seplos or JBD BMS?
Ray, Do you have a preference on BMS's? This would be for Marine Batteries, Jenny is quoting cells and cases, I just need BMS' and she sells JK, I thought Daly and JBD were preferred but wanted your thoughts and input please.
@@RayBuildsCoolStuff Jenny has a 4S box, this is for a boat, the larger Apexium cases would be fantastic for the house (next project). I really need about 800 - 900AH of battery so solar matches, what Jenny has gets me to 1100AH, although that would be better, I would need to add solar panels or replace my two LG405 bi facials with larger ones. Space is the constraint on a boat. I will see if Jenny has a seplos for the 4S style of box, if not, what are your suggestions? Thank you in advance
Hi Ray, first of all thank you for your knowledge sharing ... i have one question on you, how are you satisfied with Seplos BMS? balancing current is enough to control all cells?
hello thank you for a tutorial I am French and I would like an aid on a problem on a seplos which has 53V of tension B- and b+ and 0v on p- and p+ all the conservatives are ok and the black and white conector also I do not understand c 'is new !!! Thank you for the aid?
Hello Ray - loving your material. Question: Is building your own BMS and wiring looms a more affordable way to go versus purchases a all-in-one type/style of BMS that would be more plug and play? Thanks!
I don't understand your question. If you mean assembling batteries then yes if you discount your time. I will always build my own to have control of the quality and performance. If you mean building your own battery management system, then no.
@@RayBuildsCoolStuff - thanks for getting back to me. To clarify: asking if it is just as affordable to purchase a BMS device that already pre-fab’d, is plug and go versus buying a BMS PCB and manually wiring and configuring/engineering the setup or system? Perhaps I stand corrected with this question in regards to the BMS subject. Thanks!
@@energydreamer5347 the battery is the cells and a BMS. The BMS is just the control board that manages the battery. I have not yet seen a manufactured battery that impresses me. Many work but when they have problems, resolution is a challenge as can be seen in threads on the diysolarforum.
This may be a silly question, but does changing the length of the sense wire not increase the resistance of that wire above what the BMS is expecting? Won’t that affect the BMS’s readings?
I asked myself that question and ran it around in my squirrel cage and then decided it is probably lost in the noise. It may make a difference but the extra I left on the short runs double back in rather tight bends which may also cause resistance that is different from wire to wire. Then I had a thought of freedom and said eff it. If there is a difference it is probably the cell not the sensing wire.
It shouldn't matter. Sense wires, if that's all they are doing, have essentially no current load so no real voltage drop. There are rules of thumb for minimum bend radius for different wire types and insulation but that's a physical constraint. sharp bends electrically matter for high frequency and coax cables.
Yes, when I finish wiring and cleaning up I end up with two Woden knside the pack and one on each side but it really won’t matter as they will be in a climate controlled environment and even without it the construction and thermal mass of the rainwater tank would never let it freeze. I really doubt the mini split will ever run in heat mode but we will know soon.
No and I would not try to reattach them. There is a much longer answer but bottom line is get it replaced or drill and tap and that is a sketch proposition requiring study and experience.
@@RayBuildsCoolStuffhello again atp I’m binge watching all of your videos these are very informative to my build so thank you .. I was looking for the video explaining how u like the seplos bms because I brought a Daly wondering should I use it or send it back for the seplos. Where is your video on it
Now I saw that video the other day where you were hooking the batteries up in a super solar s*** and you wanted to mobile the same link so they would charge discharge at the same rate now I don't know maybe that isn't gonna make a difference on your voltage since and why are you not but you extended for those out I'm curious why you didn't just relocate to be VMS alongside I mean I know you're already started building the cabinets but I guess the same stuff right and somewhere along the way so much for text to voice
A mighty fine book at that, along with a handy psychrometric chart. It's funny how many times I've looked down at that chart to confirm the calculation I ran in my head for figuring out a dew point or relative humidity. That's probably something else you don't see everyday. Thanks for subscribing.
Why does the thumbnail bother you? I can understand if it misled you but the thumbnail shows the wiring harness adjacent to the Seplos BMS. The screen grabs provided by youtube were terrible. I'm trying.
