The Smartshunt 500 has a male VE.Direct cable end and the CerboGX also shows a male end. I wonder if i can cut off the smartshunt cable end and use a female Mini 4 Pin Jst Ph2.0 Connector Plug, to connect directly to the cerbo GX.
Just use a regular VE.Direct cable at the length you need - they’re available as short as ~1’ so no problems there.
I’m assuming you mean the SmartShunt IP65, which has the attached cable, as the SmartShunt does not have a cable attached. In either case, though, just grab yourself a VE.Direct cable - no point trying to mickey mouse something together and risk the operation of your system when the proper and supported solution costs like $13
Point taken i will do that
