Perhaps on a golf course, where the Controller is programmed not to exceed 10-12 mph and it's primarily flat ground.
I've got $100 for anyone who can get their Lithium powered golf car range to 50% of the Amperage, on Villages MMP's at normal Villages cruising speed of 19 mph.

Battery drain is fairly consistent at 7 miles per 10% of battery with a cruising speed of 24. Allowing for never going below 10% charge, my max range is in the 60-65 mile range.
Folks saying they can go 60 miles on a 100ah battery seems far fetched. I don't care how well engineered the cart is. My guess is that their speedometer is not set correctly and is not showing the correct mileage. I agree with the poster that offered $100 to see it done in real life - I would come to watch and document - as an engineer, I don't think it's possible.

It's not possible.
My mileage with 210 Amp is almost identical to yours. People believe their "power gauge" on their cart and start doing multiplication. After the 2nd time I ran out of power in a Lithium Loaner cart, I learned my lesson. I can get 40 miles or so on the first 1/2 of my gauge and about 20-25 on the last half.
No one wants to admit they actually ran their Battery dry, for fear of being called stupid. Instead, they extrapolate their mileage range by going 10 miles and reading their gauge.
Although if you notice, the last guy who boasted he can get 60 miles from his 105 Amp battery, has now amended his "cruising speed" to 15 mph. That's not exactly cruising, nor even "ambling". He'll be getting run over by bicyclists and walkers, right before he gets stranded at the 35 mile marker.
It's like a gas gauge on a 40 year old car. Accuracy is not a hallmark.
