Jbd bms cable

[t.brent]

I had ordered two 16s 48 v 200a bms from some knucklehead on eBay. Well only one arrived. After numerous attempts to contact, him wanting pictures of what I didn't get...yea I know, he refunded me half of my order. It's going to be a pain to return the one I did receive. I wouldn't mind keeping, but it is missing the UART cable for the display. I have spent a couple of hours looking but can't seem to find. Any ideas. It is four wires and has the same locking connector on both ends.
Thanks for any help

Post a photo of the UART port. They have had 2 different types.

The HY2.0 4Pin cable worked for me:

Mof, thanks a million,, I think you nailed it for me. First time using AliExpress....had to buy five. Even if they are wrong I'm out a buck fifteen. I hope you guys will be as much help when I put these two 16s packs together. I just know I will need help. Thanks again

We won't. You won't need us. Plenty of guides and videos out there.

Using an X-Acto knife, it is possible to shave off the ridges on the top of a PH2.0 connector and have it fit in the JBD UART port.
I did this in a pinch while waiting for the correct connector to arrive. It takes a little jiggle, but will slide in and make a solid connection. 2.0MM spacing is key, and the PH connector I had is fairly flat like the HY2.0.
