g29 battery batteries

Ok so I’m new to carts, I have a Yamaha G29 48v with the Navitas 4k ac kit with 600 amp controller and heavy duty solenoid, batteries are of different ages 3 hold voltage at around 8.2v-8.3v, 3 of em will drop to around 7 and hold when not on charge, cart will run perfect for a few minutes and...

In my 2007 Yamaha G29 golf cart, can I run two 24 volt Hawker (or similar) batteries instead of the standard four 12 volt batteries?
