The plan was easy: quickly disconnect the existing Pace BMS and temporarily connect the new JK BMS, so I could test its parallel function.
After taking the front panel off the Jaki battery, I realised, that the new JK BMS is a perfect substitute for the PACE BMS: mounting holes, power and comms cables, everything seemed to fit perfectly. So, I did it and replaced the Pace BMS with the JK BMS permanently. Fits like a glove!
We still need to do some work on the display though. But is it actually needed?
I also show how to update the Firmware on the JK-BMS and explain the charging logic of the new JK firmware V14.13
New JK-BMS with full charge algorithm and surprise functions we always wanted. Is THAT the one?

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.

@andrew81632 6 месяцев назад

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.

@ivoscuka8537 6 месяцев назад

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 :-) ...

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.

@ThePykon 6 месяцев назад

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!

@OffGridGarageAustralia 6 месяцев назад

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 (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-B8O-62Y1dZA.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.

I'm pondering which way I'll go but I have a month to go before my cells come.

@typxxilps 6 месяцев назад

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.

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 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.

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?

@OffGridGarageAustralia 6 месяцев назад

Not true. I'm curious. Hence this channel where I do tests which nobody else does. I would do all these tests even without RU-vid. That's how I started. Then I said, hey put them on RU-vid, 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.

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, ...

@tiborchren 6 месяцев назад

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....

@OffGridGarageAustralia 6 месяцев назад

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.

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

@OffGridGarageAustralia 6 месяцев назад

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!

@lezbriddon 6 месяцев назад

@@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......

@RolandOfGileadOnYT 6 месяцев назад

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?

@OffGridGarageAustralia 6 месяцев назад

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?

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

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.

@MrElciupacabra 6 месяцев назад

it doesn't seem right that BMS is doing your battery management charging instead of your victron.

@OffGridGarageAustralia 6 месяцев назад

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.

@MrElciupacabra 6 месяцев назад

@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.
