Thanks for sharing Ross, Very neat and tide Well done 👍
Very cool, and nice tour of your system.
Yeah, very neat and clearly well thought through.
Thanks
Nice built, Ross. Love the stainless battery boxes!
Thanks Andy, but they are not stainless they are gal sheet metal, keep up the good work on the JK BMS
@@sjdtmv Ah, right, I thought, you said stainless. They look fantastic!

nice job mate 😉
Thanks mate
My hat's off to you sir! Excellent design and workmanship! Would you be so kind as to say where you obtained the box and how you made such clean cuts for the openings for the connectors and display?
I am a Welder-Boilermaker and made the boxes myself at home, so working with steel is 2nd nature to me
Nice job, just wondering why the 4 pole mcb. Don’t worry, I’ve just read the other comments. I’m only just finding out about bidirectional MCBs here in UK. Have they been a thing over there very long or is OZ also just getting into them. Cheers.
Thanks, I have never come across them being use in DIY solar on UA-cam yet.
Hi, UK here...can you explain the orange connector block please ? Thanks...Awesome looking build btw, impressive stuff !
I have updated the description to include some parts
Have you experienced the issue where if you turn off the batteries for a few days (not sure how long exactly) the BMS will lose all of its settings for LiFePO4 and revert back to Li-Ion? It will change your maximum charge to 4.2V!!!!! You can see this explained in the latest Off-Grid Garage video.
I have been waiting to buy one of these off AliExpress but they keep saying "Preorder". I guess that was a good thing. Now, I think I will wait tile they get this latest issue fixed.
I have seen Andy's video, and I have not powered down the BMS to see what happens, there is an update to fix this issue and I think the default settings will change from Lithium Ion to LTO as part of that update
@@sjdtmv Yeh, i just noticed a comment on Andy's video showing a bug fix log firmware 14.17 from JK supposedly fixing this problem and like you said also changing the default to LiFePO4. I hope that it's true. I am waiting for these to go back on sale.
Just updated to v14.20 that has tested so far with no bugs
Bonsoir Monsieur, cela fait un moment que je vous regarde.
J’ai enfin construit ma batterie…
Par contre pouvez vous m’aider car je rencontre un problème de connection RJ45 CAN entre la carte bms JK et l’onduleur Growatt SPF5000 ES.
Merci de votre retour.

Great job on your battery build. What inverter are you using and have you gotten this BMS to communicate with your inverter?
Will setup on a Victron
@@sjdtmv Cool. Do keep us posted on your progress. These new JK BMS devices are really interesting.
watching from Melbourne, can you please provide the battery box link please for 16 EVE 304ah cells and same JK bms. thanks
These battery boxes are handmade by myself, they are not over the shelf item, they are of my own design
Bonsoir, je suis en montage d'une batterie comme la votre, serait il possible d'avoir le plan de connection de votre disjoncteur. Merci d'avance. Pascal
www.aliexpress.com/item/1005004155269350.html?spm You will see the wiring setup for a 4P in the pictures on this page
@@sjdtmv justement cela m'intrigue, pourquoi monter en boucles ?
@@pascalbudin2983 DC breaker are directional to work at there rated trip, when used with a battery bank this become bi-directional with flow going in both direction, the 4P breaker allows the trip to happen whether it is inward or outward current flow from the battery bank
@@sjdtmv merci de votre réponse, je comprend mieux.
Mais ce disjoncteur est indisponible sur Aliexpress en destination pour la France... Avez vous un équivalent?
Autre question, est il possible de mettre les batteries couché sur le coté?, ou est il obligatoire que soit a la verticale ?
Merci de votre retour.
@@pascalbudin2983 Sorry I didn't know that AliExpress would not deliver to France, I do not have another alternative, batteries can be tipped on there side without any problems
Very nice build! JK BMS from v14.xx or v15.xx ?
V.14, just updated the firmware to v14.20
