Catch, make or grow everything you can.
iirc it is a JST GH 4 pin 1.25mm pitch
Excellent Thank you...Now I will try and find a supplier.

What's in a title?
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.
$0.60 | HY2.0 Connector with 20cm 26AWG Cable Wire Butt Connection 2 3 4 5 6 7 8 Pin 2.0mm Pitch Male Female Plug Socket

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

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 !

Can anyone identify the connectors used on the new black JK BMS, for the No3 LCD display 6pin 1mm pitch and carries a thin spade locator - NOT JST AFAIK. Mini JST SH 1.0mm Pitch Wire Connector SH 1mm.

Possibly JST NSH? This is your friend:

I thought the JST GH was closer but depends on the pitch

Wow guys, this JST NSH https://www.jst-mfg.com/product/pdf/eng/eNSH.pdf is a nightmare. the whole 1.0mm pitch x6 is smaller than my pinkie and I would need special crimp tool to assemble a male wired plug. This is a serious issue against JK BMS cos any loss of connector cables means your BMS is a brick.
I got a remote indicator for use on my golf cart but I need ca 2m of cable between the battery and the drivers dashboard. I shall have to cut the cable and insert a 6 core 28AWG cable length etc to make it all work. I am not impressed - this is a fail point in the reliability chain. AFAIK the display also works as switch (replacing the pushbutton assy - with just 0.5m of cable - how is that supposed to be useful other than on a bench or mounted on a battery box?
Clearly there isnt enough space on the board to use the regular JST 2.0mm
