Both types of carts can reach the same speed without any modifications. They will be able to travel between 12 and 14 mph, as previously mentioned. There is one difference: battery-powered carts can slow down slightly when the charge runs low.
When you're using the 36-volt cart primarily on flat surfaces, it can carry 2 to 4 people. A 36 volt DC system can travel approximately 30 miles on a single charge. There are many advantages to the 48-volt cart, whether you choose to have it for 2, 4, or 6 passengers.
The aging of Li-ion batteries can also lead to them losing capacity or failing after a few years. Their cost is also a factor that limits their widespread adoption. It is 40% more expensive than Ni-Cd.
