VE.Direct maximum allowed voltage

VE.Direct is isolated, so it needs power from the "client" side. I want to connect it to JK BMS, but it's Power+ pin is Vbat which means around 55 V.


What is maximum allowed voltage for Power+ pin on VE.Direct on USB-VE.Direct cable and on Cerbo's VE.Direct port?

It's 5V.
The front end of a CerboGX VE.Direct interface has something like a SI8422 isolator.
