How to call a Powershell script using batch script and pass an object array

My issue is with passing the list of servers from an array variable to another script I call reboot. The array list get converted to PSCustomObject when in the other server.

code to get servers;

Import-Csv .\SMachines\Servers.csv | Where-Object {$_.ENVName -eq "RND"} | Select-Object -Property ENVName,FND,DB,APPS | Foreach {[void]$SRVList.Add($_)}
.\ParamBypass.bat /reboot.ps1 $SRVList

Expected List format

ENVName FND DB APPS ------- --- -- ---- RND srv003529 srv002983 srv003528 RND srv003527 RND srv003526 RND srv003530

variable $SRVList output whiles in reboot.ps1

@{ENVName=RND; FND=srv003529; DB=srv002983; APPS=srv003528}

I run this script with a batch file bypass;

Thanks in advance.
