Andy, your video's are inspirational. I swapped the BMS out of my 12v SOK battery a few weeks ago for a JK because my old SOK BMS lacked any control or Bluetooth. Not as plug and play as your video but it works perfectly. Very glad I bought a battery I can service.
Andy, at minute 19:30 after you switch on the BMS again, please check if the BMS has lost its settings!!! I have 3x PB2A16S20P and they all loose their settings with Firmware V14.13 when they get switched off. Also mentioned this in the comments under the other videos and I was hoping you will notice the same problem on this video.
Been enjoying these videos would be nice to see a company come out with a replacement front panel to replace the one in place and make it able to fit a jk to all them other packs you have
Well, people already complain about paying $150 for a Peter board which makes the old JK perfect. I can only imagine the outcry when they need to fork out another $100 plus shipping for a piece of metal... But let's see...
I was finally able to change the password in the app, thanks Andy. If you remember, I commented on one of your previous videos that my breakout board displayed alarm and changed the password several times. Well, I kept changing it from top left 3 lines on the app (where you can change the name of BMS) instead of Control (bottom right) 🤦♂️.
The JK - PC application is capable of communication with the older version as JK-B1A20S15P via RS485/USB cable. I tested it already. But it probably only connects at HW level, it doesn't load data. Of course I understand that JK is working on FW modifications to the new BMS versions i.e. JK-PB1A16S15P etc. However, I'm sure there are now plenty of DIY installations around the world with older versions of JK-B1A20S15P etc. And modification of the FW even on the old BMS towards Float and SOC would be great. These functions does not means HW, just software /voltage/time management. I guess it can't be assumed that all DIY will now buy a new BMS and this way the JK would ensure loyality. Kind of like MCS and WIN11 :-) ...
Hi Andy, is there a way to update the non-inverter BMSes too? I bought an b2a8s20p in 3/2023 and some days ago another one. The new one has the 100% and 0% SOC voltage setting included (and a newer FW (11.288), the older one not and an older FW (11.17) I would like to update the old one to a new SW to support the 0%/100% SOC voltage setting. Is this possible, somehow?
You may be able to mount the pool fence panels in landscape if the fence is strong enough. This may also be a nice second try for a season adjustable tilt system if the orientation is any good.
@@OffGridGarageAustralia Depending on the WAF, you could use some mounting rails and put those in the ground at an angle. When connected to the top of the pool fence this will create a sturdy triangle and maybe the angle will improve the amps as well. Another option is an off-grid dog house 😜
@@OffGridGarageAustraliaYou may be right. Just seems like a waste not to use these solar panels and looking for a solution to a "problem" like this is always fun to do.
There are three options with the display: 1. No display and the hole is blinded with a piece of sheet metal or a 3D printed cover. 2. Smaller display with 3D printed spacing frame. 3. Larger touchscreen display with increased cut-out from the original display. I would like to see all three options. It's up to everyone to decide what they like. I like best the Large touchscreen option, but is there enough space for it?
I have the 4.3" display (smaller one was on backorder at that time) and while it's better than standard displays with 4 buttons, it's utterly useless. I have it taped on the outside with double sided tape. I installed 120A breaker at the hole, DIY'ed with plexiglass and supporting bracket on the inside.
Like# 301, I got snookered, no alert and I’ve been on a ladder all day working on Taj-Ma-Haul’s solar awnings! Passenger side will be 3x540(1,620)w/hrs, driver’s side will be 6x445(2,670)w/hrs bifacial, 5 of which will face the South. 4,290w/hrs on the solar awnings!
Andy, you mentioned in the Christmas live stream for the german tech channels that your roof solar is consisting of many parallelized short strings of just 2 panels each. Did you happen to explain the reasoning of why you chose to set it up in such a way in one of your videos? I kept wondering about it, since the charge controllers will need to get to a certain startup voltage (is it 50V for the Victron charge controllers?). Can you reliably reach that start voltage even during shading conditions? What happens to the actual Maximum power point voltage in different shading conditions? The paralleling implies that there is only a single global MPP voltage for all parallelized strings. Does this work if some panels are shaded while others are in full sun? Thanks!
The main reason of these many parallel strings is the shading I have on these roofs. I did some testing with two panels in series and it worked flawlessly (ruclips.net/video/B8O-62Y1dZA/видео.html) The voltage is not different if the panel is in full sun or shaded, so startup voltage is never a problem. Also, even if one string is in full sun and another is fully shaded, they both produce power and the MPPT finds the best power point. It will mainly concentrate on the string in full sun as this is what delivers most of the current. The shaded string will just run with it and delivers a bit of current as well. In sum, I have 18 of such strings on 4 separate MPPTs and I can max out the panel peak performance. Cabling effort is a bit more of course but the efficiency is far better than just one high voltage string where some of the panels are shaded, and some are in full sun. I made many videos showing this in all details. This was all in November 2022, when they installed the solar system.
Thank you very much for the instructions. I was wondering, incase the operational BMS is accidentally damaged, what will be the safety mechanism for the battery pack system. Will the system be cut-off or the battery charge-discharge can be continued somehow?
Andy it’s just like good wine, it’s gets better and better with the years 👍 I look to download the app software for IOS on your site but i get directed to Chinese language with pc software, is that right and automatic the latest version or for what i must looking on the App Store Hopefully you find time Thanks
Hallo Andy, super toller Livestream mit Jungs aus Germernany! Interessante und lustiger Beitrag der anderen Art. Wieder einiges dazu gelernt! Vielen Dank dafür. Da ich keine Ankündigung im Vorfeld gesehen habe und dadurch keine Möglichkeit die ganze Sache nicht live sehen konnte , somit auch nicht mitchatten konnte, habe ich noch ne Frage an dich. Womit filmst du deine vids und welches Mikro benutzt du? Ganz liebe Grüsse aus dem heute mal sonnigen Ludwigsfelde und einen schönen dritten Advent
Andy, forgetting about the FW and the active balancing for a moment: what would be the advantages of the JK vs the last version of the Seplos BMS? Having two of the Seploses combined with NEEEYs, I'm thinking if with a good FW upgrade, Seplos could get close to this JK version?
well the seplos still doesent have the 1. Phone App (for some it doesent matter, for some it does) 2. biggest thing, you dont have the absorptions/Float mode. and then active balancer in the bms makes it probably the best bms out there now. but the others are not bad, they are older and are already prooven, so reliable
@@anzzgar Ok, phone app is not killing me, but float/absorption handling is a good point. On the other hand this should be a limitation of the seplos FW, not its HW?
Do you have made a video already that shows how to connect a computer to the battery? Including what software you are using and how it is with the virtual com port? That would be great. Thanks Andi and kindest regards from Austria.
Yes, quite a few videos showing that. It depends a bit what BMS and software you're using but most of these adapters are plug'n play under Windows and install themselves automatically.
I'm thinking you'll be disappointed with the JK display, the 4.3" seems to give status only and is much larger then the opening for the JBD or Pace displays so either you'll have to make hole larger or make a 3d part to have it stick out from the face plate. I'm pondering which way I'll go but I have a month to go before my cells come.
I have managed to connect the bms to the computer and update the firmware. Second problem I cannot establish CAN connection between BMS and inverter. Is a easun inverter. I try all configuration possible on the cable but always error 61. Waiting to see how it works on combination victron jk.
Have you tried connecting the old display to the jk bms with a custom cable? Most of the displays in Chinese electronics are very basic and just need 4 wires; vcc, ground, tx, and rx.
THX for the Video again Andy I just mentioned the JK Comm.-Board has 6 SOC LEDs but the Pace has only 4 - will the SOC be displayed correctely or not? Also i saw the printing on the jaki battery points to the wrong direction - maybe this should be also configurable in the JK BMS Grüße
thx for this interesting video! Does the v14.13 firmware require a specific hardware revision of the JK-PB2A16S15P / JK-PB2A16S20P? the one on your website is silver, the one in the video is black...?
Hi Andy, great videos thank you. Any chance you could try have this new JK BMS in parallel with the global power/pace BMS and see if they work together. Also maybe load the JK BMS firmware on the global power/pace BMS?
Hello Andy, I'm building a gobel power kit with a 4A heltec (same as neey) active balancer. Do you recommend to top balance the cells or it's useless with active balancer ?
I guess it is time for a battery container based on the amount of batteries you are collecting or using ? More than ever before, but I still wonder when Seplos will deliver their new MASON 280 L , the power tower cause that is more or less a well designed furniture with 15 kWh and a ususal 8mm terminal - but on strong heavy duty wheels. We got one when it became available in late november in Germany, the case for 500€ incl. battery cable 50mm². 1830€ for 16 EVE LF280K with a complete Seplos BMS meant that we got a battery for 2500€ incl. the Neey 4 compared to our first 8 kWh battery, also SEPLOS BMS with EVE LF160 cells which was about 1.800€ without such beautifull case which is no longer black, but a whit tower 88 cm from the ground, 42cm wide and about 26 cm deep. Seplos BMS was needed due to a fleet of 8 Growatt inverters, cause we have 14 Strings to minimize the impact of shadows which means about 4 panels for 30 kWp. I guess I will get a JK BMS later in 2024 when they will support growatt inverters too just to start with the 8 kWh battery (grade b cells) - compared to the LF 280 K which were grade a and have 25 Ah more capacity than the 280 Ah promised at least if you test them at 22°C. the difference if you charge them fully is tiny and you do not need to balance while the grade b need a lot of balancing, at least 2 times a month while still having 160,5 Ah capacity as at delivery.
is firmware update a Service Engineer's task only? mean why Users have to look for recent firmware on 3rdparty resources, taking risk to get incompatible one, while JK PC software could download a proper latest and greatest version from Manufacturers site? like Victron does, like dozen of other hardware does: PC BIOS, NVMe / speakerphones / keyboards maintenance software, etc.
Next BMS swap: New JK in, Seplos OUT and so on ... How long Seplos, Pace and other BMS manufacturers did not deliver what users wanted and users needed to adapt to them, these times are hopefully over with the new JK Inverter BMS.
Firmware best done over a cable. Otherwise the chance of building brick houses and rooms increase significantly. If you take a usb to cat, I think you’ll be able to use a tablet or phone. But the program that is used I think is windows is specific. I don’t think it will run on a phone. On a tablet with virtualisation you’ll be able to do it. Or get an old used laptop that has a lan port (I know they are going out of vogue because the new kids don’t understand these things and companies save on components).
@@asderven Updates via cable is ancient history. My inverter gets FW update remotely, wirelessly. I bet victron is too. Bricks no longer happen with file checksum to ensure correctness of the file.
@@DanBurgaud I am still too scared to do firmware updates remotely. Good to know we don't get bricks anymore. Most of my hardware on the computer side is connected via cables, so haven't had the chance to update remotely the past 10-15 years. Which inverter do you use? I am learning the fascinating world of rebranding in solar inverters. Each country renames a few major inverters. Others like growatt keep their original names. In china there only a few direct manufacturers. Sometimes inverters being sold in different countries are running the same program or software side, I find that fascinating. Because the price difference is immense 😶. This is usually lack of transparent price information across countries even after factoring in taxes, customs, duties, transportation etc.
Hi Andy , I am trying to do a similar thing but I cant update the firmware , and I always get the " Device Identify is not same to connected Device Error" . I actually tried with all the firmware versions (150 ,200 Amp 1/2A balance) . I am certain I have the correct firmware downloaded but I just get the same Error. Any suggestions?
It would be interesting to test if the master settings can update slave charge settings rather than just override them while they're connected (assuming the same level of firmware).
@@rockyfox7087 ok, thanks. It would be a useful way of propagating settings if using up to 16 daisy-chained BMSes, I guess. But you'd still need to set things like the capacity so maybe it's generally not considered useful.
@@davidpenfold its not a big issue if you have to set it up for one time, but right now this firmware has a bug it resets all the sett when you turn the bms off, besides many other issues Still needs some time to be perfect
@@serverrackbatteryusa That would take some work and time, but it does feel like the upgrade is worth it. I am considering a Jakiper home battery, but Sodium-Ion and a great loadbalancers make me a little more patient.
Hey Andi, what‘s your opinion on an JK-BMS with 18S for the Victron-System? The MultiPlus II should be able to handle 18S as far as I understand… I did not find a JK-BMS with 18S unfortunately…
and... has anyone found a diy battery box (48V / 280Ah) where at least the communication board from the JK-BMS fits in? the Basen Green from Shenzhen Basen looks good, just the dry contacts opening is missing.
Ask ELL battery, when they start to sell DIY battery box with New JK Inverter BMS. They planned to sell, this what they answer to me on their webchat (before Andy part 2 about this BMS) but when this BMS not work I assume they wait when JK fix it. Maybee now they wait how communication between more BMS will work....
I see an rs 232 adapter there that looks like what I think is called a db9 connector. Then you get db9 back to rj45. Looks like there are direct converters online if you poke around, but I don't think Andy got the rs232 to work. What I'm looking for is usb c to rs485, with the rs485 connector being the rj45 (same as ethernet plug format) .@@Vitalya01081988
But before I do the update, I'll wait to find out if the BMS works well in parallel with a second BMS because I don't feel like doing a second update right away. 😊
Looks like I have the same issues with connecting to the PC like you had with your first JK-PB2A16S20P, I can't get any connection to the BMS via the PC software; I tried 3 different RS485 adapters, using multiple Cat5 cables, tried all RS-485 ports with all possible dipswitch settings on the BMS?? Do you have any idea? My BMS is still running V14.04 and I can't upload the new firmware as I can't get the connection via the PC working... Kinda frustrating so understand how you must have felt Andy! ;-) Anyone any suggestions on what to try next?
@@Lifepo4Clown yup found it by ordering the specific Seplos adapter which solved the issue.... so BMS is updated to V4.15 now but next challenge is to connect the BMS to my Cerbo GX. Not quite sure which ports to use on the Cerbo and on the BMS... tried all options but no success so far?! Anyone any tips?
I just finally got it to work! Used the VE-CAN B type cable now; dipswitch on BMS set to 1, I had to use the RS485 port next to the CAN port (just like Andy). Using the RS485A or RS485B didn't work! VE-CAN port profile (Settings > Services > VE-CAN port) set to CAN-bus BMS (500kbit/s)
I want to use a AC heater for my batteries, and I have a jk bms, now I know the bms isnt for AC but should work with a relay or a SSR, just a little unsure how to connect the relay coil/ssr input to the bms, anyone done this with success? my instruction leaflet is rather lacking in connection details for the heater port
I've asked JK several times but got only a hand-drawn sketch with no further instructions or specs how to connect. Apparently, there is a cable you can buy from them but again, no real manual or how-to guide. I'll follow this up!
@@OffGridGarageAustralia mine came with a cable, one black wire and three green..... I've decided to use simple electronics set at 3c and turn on a simple heater under them. Off course then there's the thermal mass issue, case temp won't reflect core temp, so you could think they are warm enough when they have not cooked through, I wonder if it's the same timing as Xmas turkey......
When I go to the URL for JK that's on the BMS, I get this half baked unsecure (no SSL) website, when I remove the "-" character, I get a decent website. Which one is the real JK BMS website?
www.jkbms.net/ is the official website. No https in 2023... 🤦♂️ Would you trust such a company to look after your battery to prevent any accidents which can burn down your house?
As you can see, after crimping you have a flat side, this is normally on the eye side and the somewhat round crimp belongs on the cable side. And the dots indicate whether you have used the correct color. 1 point is red, 2 is blue and 3 is yellow.
Just wondering ... do you ever get to the place with the equipment you have and say to yourself "Hey, this is working. I don't care if there are new gizmos coming out. I'm sticking with what's working regardless. I'm wondering how often you trade in your car, even though the one you have may be doing all you need it to do? I'm guessing many of the changes you make are for the sake of your video watchers? True or not?
Not true. I'm curious. Hence this channel where I do tests which nobody else does. I would do all these tests even without RUclips. That's how I started. Then I said, hey put them on RUclips, maybe others are interested too. If you are not, why are you here? 😉
Hi Andy @OffGridGarageAustralia, i have 3 5.12kW using the 100A Pace BMS that you just swapped out for the JK BMS and one of my BMS has shorted out MOSFETs. Are you able to offer/give me the Pace BMS that you just removed? will be highly grateful.
The BMS knows best what voltage the battery has, what temperature we have in the cells and what voltage delta we have across all cells. No inverter nor Victron system would have these data without the BMS. So, the BMS is the best device in your system to control charging.
@OffGridGarageAustralia sorry but I don't agree ...BMS is for protection and equilising and not for charging...charging is for inverter...BMS should not interfere in the process of charging ...only for protection and equilising cells. In my opinion Victron shouldn't know any info about cells for example...BMS manages this. Otherwise the system will be buggy and not workin properly. You could have a fault in your system and you don't know why is not chatging...is it BMS or is Victron? the system will not be well separated and this is not ok.
Hello Sir, i need Help i am searching for 64S 30 Amp BMS for Lifepo4 Battery, can you tell me where can i get it also at cheap price ! I am from India. I like your videos, they are always exciting ! Thank you !
🆘I have a wish that needs to be conveyed to the developer somehow I will describe the problem when charging from a Solis inverter, the massage by CAN are ok, but! when the charge gets closer to 100% it should send a smaller charge current via the CAN, this was on your old SW, please sent this information to JK My one is charging same current as it is set in the bms app, it don’t reduce the current while charging closer to 100% Obviously, what does it do, current are set to 50A, and from 0% it will charge to 100% with 50A, and it don’t reduce the current as it should do

thx for this interesting video! Does the v14.13 firmware require a specific hardware revision of the JK-PB2A16S15P / JK-PB2A16S20P? the one on your website is silver, the one in the video is black...?
The FW folder contains 4 files for all of their BMS, 100A, 2x 150A and 200A. Select the right one for your BMS with any of their hardware.
Thanks Andy,
@OffGridGarageAustralia Hi Andy. Great video! I would like to buy a battery from them. The codes on your website don't seem to be working?
JK does not sell batteries afaik. Do you mean BMS or batteries from another supplier?
Hi Andy, great videos thank you. Any chance you could try have this new JK BMS in parallel with the global power/pace BMS and see if they work together. Also maybe load the JK BMS firmware on the global power/pace BMS?
Hi, do you think the JK-PB2A16S20P is the same size than JK-PB2A16S10P ( so can be used on jaki battery rack) ?
10:30 That fits so well. A rogue who thinks evil of it.
Hello Andy,
I'm building a gobel power kit with a 4A heltec (same as neey) active balancer.
Do you recommend to top balance the cells or it's useless with active balancer ?
hello Andy, is this battery package with a BMS works with an Inverter with no communication, no CAN bus, i mean does the BMS master the inverter ?
You are " THE MAN IN AUSTRALIA "!!!
Nice upgrade... 🐸
Will that BMS jk communicate with lux power inverter?
15:05 You are able to update via RS485A i updated mine this way
I guess it is time for a battery container based on the amount of batteries you are collecting or using ?
More than ever before, but I still wonder when Seplos will deliver their new MASON 280 L , the power tower cause that is more or less a well designed furniture with 15 kWh and a ususal 8mm terminal - but on strong heavy duty wheels. We got one when it became available in late november in Germany, the case for 500€ incl. battery cable 50mm².
1830€ for 16 EVE LF280K with a complete Seplos BMS meant that we got a battery for 2500€ incl. the Neey 4 compared to our first 8 kWh battery, also SEPLOS BMS with EVE LF160 cells which was about 1.800€ without such beautifull case which is no longer black, but a whit tower 88 cm from the ground, 42cm wide and about 26 cm deep.
Seplos BMS was needed due to a fleet of 8 Growatt inverters, cause we have 14 Strings to minimize the impact of shadows which means about 4 panels for 30 kWp.
I guess I will get a JK BMS later in 2024 when they will support growatt inverters too just to start with the 8 kWh battery (grade b cells) - compared to the LF 280 K which were grade a and have 25 Ah more capacity than the 280 Ah promised at least if you test them at 22°C. the difference if you charge them fully is tiny and you do not need to balance while the grade b need a lot of balancing, at least 2 times a month while still having 160,5 Ah capacity as at delivery.
Can you update the older (smaller) JK to the newest firmware?
No :(
is firmware update a Service Engineer's task only? mean why Users have to look for recent firmware on 3rdparty resources, taking risk to get incompatible one, while JK PC software could download a proper latest and greatest version from Manufacturers site? like Victron does, like dozen of other hardware does: PC BIOS, NVMe / speakerphones / keyboards maintenance software, etc.
Thanks for the video. Which bms do you prefer most ? Seplos inverter bms, Jk inverter bms or jbd inverter bms.
The JK seems to be the best so far. Due to the active balancer and new firmware updates, no other BMS has these features. Not even close.
Hello,can this bms works on 24v system if i connect 8s only?
12:28: *1A active balancer
Andy, I have a problem with my jkbms, how do you contact JK support?
Go to www.jkbms.net/contact-us
Next BMS swap: New JK in, Seplos OUT and so on ...
How long Seplos, Pace and other BMS manufacturers did not deliver what users wanted and users needed to adapt to them, these times are hopefully over with the new JK Inverter BMS.
15:06 Jk should come up with an easier FW update method by having the mobile app download the FW, then feed it to the hardware via bluetooth.
ah FW Updates via bluetooth are super difficult, because if the unreliable connection gets interruped your FW can get screwed
@@anzzgar Victron seem to manage it ok. 🤔
Firmware best done over a cable. Otherwise the chance of building brick houses and rooms increase significantly. If you take a usb to cat, I think you’ll be able to use a tablet or phone. But the program that is used I think is windows is specific. I don’t think it will run on a phone. On a tablet with virtualisation you’ll be able to do it. Or get an old used laptop that has a lan port (I know they are going out of vogue because the new kids don’t understand these things and companies save on components).
@@asderven Updates via cable is ancient history. My inverter gets FW update remotely, wirelessly. I bet victron is too.
Bricks no longer happen with file checksum to ensure correctness of the file.
@@DanBurgaud I am still too scared to do firmware updates remotely. Good to know we don't get bricks anymore. Most of my hardware on the computer side is connected via cables, so haven't had the chance to update remotely the past 10-15 years.
Which inverter do you use? I am learning the fascinating world of rebranding in solar inverters. Each country renames a few major inverters. Others like growatt keep their original names. In china there only a few direct manufacturers. Sometimes inverters being sold in different countries are running the same program or software side, I find that fascinating. Because the price difference is immense 😶. This is usually lack of transparent price information across countries even after factoring in taxes, customs, duties, transportation etc.
Nice work 👌🇦🇺
Hi Andy , I am trying to do a similar thing but I cant update the firmware , and I always get the " Device Identify is not same to connected Device Error" . I actually tried with all the firmware versions (150 ,200 Amp 1/2A balance) . I am certain I have the correct firmware downloaded but I just get the same Error. Any suggestions?
I have the same problem. Only "forced update" is an option
Comm is connected it says but i have no further BMS info on the screen
Hello Andy nice video, My Q is , can we save, export , import firmware software from this BMS?
You mean settings? No, not yet, it's on my list to request for a future update.
Where did you get the jkbms software and firmware updates? Will that work for jk-b2a24p20s?
Or...Can the older JK work as the slave with the new features?
It would be interesting to test if the master settings can update slave charge settings rather than just override them while they're connected (assuming the same level of firmware).
No it doesn’t do anything with the slave batteries, I already tested it
@@rockyfox7087 ok, thanks. It would be a useful way of propagating settings if using up to 16 daisy-chained BMSes, I guess. But you'd still need to set things like the capacity so maybe it's generally not considered useful.
@@davidpenfold its not a big issue if you have to set it up for one time, but right now this firmware has a bug it resets all the sett when you turn the bms off, besides many other issues
Still needs some time to be perfect
JK BMS and Jakiper build quality seems like a good match. Any chance that this will be a factory built configuration?
Jakiper battery use PACE BMS and other component applied UL & CE safety certs, if change, need to apply new UL, & CE as per the parts used.
@@serverrackbatteryusa That would take some work and time, but it does feel like the upgrade is worth it. I am considering a Jakiper home battery, but Sodium-Ion and a great loadbalancers make me a little more patient.
Hey Andi, what‘s your opinion on an JK-BMS with 18S for the Victron-System? The MultiPlus II should be able to handle 18S as far as I understand… I did not find a JK-BMS with 18S unfortunately…
JKs support up to 24 cells in series. Choose the top models.
@@bloodcarver913 Also the new one?
YT channel meintechblog is running Victron on 18S
I have two USB-C to RS485 adaptors and neither one will give me a comport.
Can anyone direct me to where I can buy the right one that works.
and... has anyone found a diy battery box (48V / 280Ah) where at least the communication board from the JK-BMS fits in? the Basen Green from Shenzhen Basen looks good, just the dry contacts opening is missing.
i'm also interested about finding a diy battery box, ...
Ask ELL battery, when they start to sell DIY battery box with New JK Inverter BMS. They planned to sell, this what they answer to me on their webchat (before Andy part 2 about this BMS) but when this BMS not work I assume they wait when JK fix it. Maybee now they wait how communication between more BMS will work....
I will design some 3D adapter plates, so the JK will fit into any of the DIY boxes. That will be a lot of fun.
Andy, do you have a link to this RS485 usb to rj45 adapter on your web-site?
Is this just an adapter that just adapts the connector format, or is there some electronics involved?
Nevermind, found it in the Pre-assembled Lithium Batteries section of your web-site
Його можна самому зробити з usb rs485 адаптера
I see an rs 232 adapter there that looks like what I think is called a db9 connector. Then you get db9 back to rj45. Looks like there are direct converters online if you poke around, but I don't think Andy got the rs232 to work. What I'm looking for is usb c to rs485, with the rs485 connector being the rj45 (same as ethernet plug format) .@@Vitalya01081988
Hi Andy
I battle to install Jikong app. What other patches do I need to install on my Samsung Android phone? Can you assist.
You scan the QR code on the BMS and download the app. How old is your phone?
I just wanted to ask you if you could make this kind of video because I don't really understand how the update works. 😄
But before I do the update, I'll wait to find out if the BMS works well in parallel with a second BMS because I don't feel like doing a second update right away. 😊
Looks like I have the same issues with connecting to the PC like you had with your first JK-PB2A16S20P, I can't get any connection to the BMS via the PC software; I tried 3 different RS485 adapters, using multiple Cat5 cables, tried all RS-485 ports with all possible dipswitch settings on the BMS?? Do you have any idea? My BMS is still running V14.04 and I can't upload the new firmware as I can't get the connection via the PC working... Kinda frustrating so understand how you must have felt Andy! ;-)
Anyone any suggestions on what to try next?
Is het jou al gelukt, Rik? Heb precies hetzelfde rot probleem....
@@Lifepo4Clown yup found it by ordering the specific Seplos adapter which solved the issue.... so BMS is updated to V4.15 now but next challenge is to connect the BMS to my Cerbo GX. Not quite sure which ports to use on the Cerbo and on the BMS... tried all options but no success so far?!
Anyone any tips?
I just finally got it to work! Used the VE-CAN B type cable now; dipswitch on BMS set to 1, I had to use the RS485 port next to the CAN port (just like Andy). Using the RS485A or RS485B didn't work! VE-CAN port profile (Settings > Services > VE-CAN port) set to CAN-bus BMS (500kbit/s)
I want to use a AC heater for my batteries, and I have a jk bms, now I know the bms isnt for AC but should work with a relay or a SSR, just a little unsure how to connect the relay coil/ssr input to the bms, anyone done this with success? my instruction leaflet is rather lacking in connection details for the heater port
I've asked JK several times but got only a hand-drawn sketch with no further instructions or specs how to connect. Apparently, there is a cable you can buy from them but again, no real manual or how-to guide.
I'll follow this up!
@@OffGridGarageAustralia mine came with a cable, one black wire and three green.....
I've decided to use simple electronics set at 3c and turn on a simple heater under them. Off course then there's the thermal mass issue, case temp won't reflect core temp, so you could think they are warm enough when they have not cooked through, I wonder if it's the same timing as Xmas turkey......
pace not good ?
Does it fit into SEPLOS case?
No
Time to put the AC back on again.
JK-BMS-MONITOR 2.4.019 Works with Windows 7 64 bit?
It should work, yes.
When I go to the URL for JK that's on the BMS, I get this half baked unsecure (no SSL) website, when I remove the "-" character, I get a decent website. Which one is the real JK BMS website?
www.jkbms.net/ is the official website.
No https in 2023... 🤦♂️
Would you trust such a company to look after your battery to prevent any accidents which can burn down your house?
I thought the phrase was oh buggah!
you are using the crimping pliers incorrectly.
How so?
As you can see, after crimping you have a flat side, this is normally on the eye side and the somewhat round crimp belongs on the cable side.
And the dots indicate whether you have used the correct color.
1 point is red, 2 is blue and 3 is yellow.
Hi everyone, Has anyone tried to connect communication between a PACE BMS and a JK BMS in parallel?
Just wondering ... do you ever get to the place with the equipment you have and say to yourself "Hey, this is working. I don't care if there are new gizmos coming out. I'm sticking with what's working regardless. I'm wondering how often you trade in your car, even though the one you have may be doing all you need it to do? I'm guessing many of the changes you make are for the sake of your video watchers? True or not?
Not true. I'm curious. Hence this channel where I do tests which nobody else does.
I would do all these tests even without RUclips. That's how I started. Then I said, hey put them on RUclips, maybe others are interested too. If you are not, why are you here? 😉
I don’t understand why you don’t install a mini split air conditioner in the garage you have plenty of solar overhead now and they are very efficient.
Hi Andy @OffGridGarageAustralia, i have 3 5.12kW using the 100A Pace BMS that you just swapped out for the JK BMS and one of my BMS has shorted out MOSFETs. Are you able to offer/give me the Pace BMS that you just removed? will be highly grateful.
Wasn't that long ago you were arguing for float charging lithium! 😂
I still do!
it doesn't seem right that
BMS is doing your battery management charging instead of your victron.
The BMS knows best what voltage the battery has, what temperature we have in the cells and what voltage delta we have across all cells. No inverter nor Victron system would have these data without the BMS. So, the BMS is the best device in your system to control charging.
@OffGridGarageAustralia sorry but I don't agree ...BMS is for protection and equilising and not for charging...charging is for inverter...BMS should not interfere in the process of charging ...only for protection and equilising cells.
In my opinion Victron shouldn't know any info about cells for example...BMS manages this. Otherwise the system will be buggy and not workin properly.
You could have a fault in your system and you don't know why is not chatging...is it BMS or is Victron?
the system will not be well separated and this is not ok.
Aber das Display kann man weiter verwenden,nehme ich an.
Hello Sir, i need Help i am searching for 64S 30 Amp BMS for Lifepo4 Battery, can you tell me where can i get it also at cheap price ! I am from India.
I like your videos, they are always exciting !
Thank you !
PLease make video from 123Smart BMS.
No more neeeeed for a neeeeeeeyyyyeeeee
👏👏👏👏💪❤️
🆘I have a wish that needs to be conveyed to the developer somehow
I will describe the problem when charging from a Solis inverter, the massage by CAN are ok, but! when the charge gets closer to 100% it should send a smaller charge current via the CAN, this was on your old SW, please sent this information to JK
My one is charging same current as it is set in the bms app, it don’t reduce the current while charging closer to 100%
Obviously, what does it do, current are set to 50A, and from 0% it will charge to 100% with 50A, and it don’t reduce the current as it should do
✌
My password is not 123456, can anyone help😢
🐸🐸🐸
5:06 häh häh hää :)
that crimp is not perfect, its upside down, the 2 dots should be on the ring side, not the wire side.
I'm in Down Under. Maybe that's why🙃
Your welcome to come by and check out my solar system in Canada, -12DegC and haven't seen the sun in over a week.
Lol, yeah i hear you there. Today is the first sunny day in over a month!
