I have a 24 V battery and a Daly bms

When I check the voltage from one end of the battery to the other I get 27.1 V

when I short out the negative cables off the BMS and then plug in the balance leads it starts out at 27.1 V and then the voltage continues to drop until it reaches the 14 v range, if I check the voltage is the battery it’s still 27.1 V

I double check the continuity of every BMS lead and everything seems to be connected properly...... shut out the negative leads against each other and again it goes back to 27.1 V and then gradually drops

what am I missing here?
