Figuring out Battery Solutions on my Yamaha G29 Drive Golf Cart!

Looking for some ideas on the Yamaha Golf cart for a 48v system. I pulled the trigger on the "okay" batteries off of marketplace and should have probably just bought some off amazon!
I painted the cart nardo gray, hydro dipped some parts in a forged carbon and put a headlight/brakelight kit on it and replaced the steering wheel.
Parts I used:
Modz Tires I have on the cart: amzn.to/3wIOJO3
Lift Kit I used: amzn.to/3yjyc3o
Seat Kit: amzn.to/4dHL6Zj
Steering Wheel: amzn.to/3zOzFzK
Headlight/Brake Light/Horn Kit: amzn.to/3y463h9
Any guidance or thoughts on how to improve this rig without breaking the bank?
Thanks for watching all!
