36 volt vs 48 volt

Looking for input on this important question. What really is the difference between a 36 volt cart and a 48 volt cart. (beyond the 12 volts).
I’ve seem some claims that 36 volt will have more torque. I also hear that 48 volt will give better “performance”. But what are the real details and what is the real truth. What defines “performance” anyway?
Club Car was the first to create a 48 volt cart along with Trojan batteries. Was this a real innovation and step forward? Or was it just a way to sell carts and batteries?
Please leave a comment with your thoughts on the subject!
48 volt is really a scam to try to make more money off of batteries and upgrades. There is no difference in power between the 36 and 48 volt golf carts!
I recently purchased a used (like brand new) club car w/ a 36volt battery system. It seems to run slower than others in my park and requires charging more often (like every time I use it). is that a sure indicator that I need to replace the batteries? The fluid levels are all fine.
There is a good chance those are the original batteries. Check with the battery manufacturer and find out where the date code is printed on the batteries. That will help you determine how old they are and if they need replacing.

Thank you for your reply. I failed to mention that the golf car sat in the garage unused for a long time. Would that contribute to the apparent deterioration?
