This is how I understand your setup:

    ,------,
    |CP1500|=======Pi  + NUT server + client   OK
    '------'       |
                  Lan
                   |-------ESXI + NUT client   Shutdown at 50%
                   |-------QNAP + NUT client

Could you show us the NUT client configuration on ESXI?  upsmon, upssched and 
upssched-cmd if you use it.

I don't understand, surely the ESXI and the QNAP are independent of one another 
for their shutdown behaviour?

This is surprizing.  If the QNAP is running a NUT client, why is it limited to 
just a number of minutes, and not using the battery charge?
