Current Connected 150a JBD BMS

[Pater C]

I'm looking for a wiring diagram the current connected 150a JBD BMS. There is not a wiring guide on current connected's website. Sunfunkits (

) seems to use this BMS and wires the B- terminals with a y cable to the negative of the batteries. I am wondering about the C- terminals. In Sunfunkits video a short y connector is used to connect the negative terminal of the battery box. I am not using a battery box and I am going to a negative bus bar. Any ideas if I should make a y cable that goes from the two C- to the busbar or if I should make a short y cable and then a longer cable to the busbar?

JBD has wiring diagrams on their Aliexpress page. Here's a 150A BMS listing: https://www.aliexpress.com/item/1005002328847169.html
Scroll down that page for the wiring diagram.

Thanks, @WingNut the page you linked wasn’t quite my BMS, but it led me to page that was. Ali express bms. I also found this post helpful. It basically answered my concern about the proper gauge wire to use.

They have a diagram on their website now, it’s not easy to find though….
