Excellent Thank you...Now I will try and find a supplier.

Would you know what type of connectors the Can (3 Pin) and the LCD (6 Pin) connectors. Thanks

Edit - probably bad info below but I'll leave it for anyone with a JBD.


They look like the same size as JBDs, you'll need to measure and make sure.

I used these, they shipped quick; make sure you select the version you need.

Hello Bundyblu,

I'm starting a new project to extend to JK-BMS a 6 months logger I made for DALY BMS .
I already found all the protocol info I need to communicate with JK , the only doubt I still have is coming from the DS : http://www.jk-bms.com/en/Upload/2023-12-05/1746328565.pdf
I will use UART connector to be compatible with my current HW.
UART connector is "P5" on JK meant for GPS. Is a 4 pin JST 1.25 ( or it should be )
Pin P5.1 is stated to be VGPS ( ... close to B+ ) .
QUESTION: Have you tested this Pin during your development ? is really B+ ( on 16S it should be around 50V that makes no sense for me )
Thanks for replying.
P.S. asking because I don't have a JK-BMS - I will work blindly this time .... simply trying to add the JK protocol .

For your ( and my fun ) this is a Zoom IN of a 24h log from my logger notes - yellow boxes and red arrow are added later

I think I found the answer by myself ... YES VGPS is B+ , I won't use it . Activity to make my dongle compatible with JK already at a very good point . Stay tuned !
