Swapped out the ECV in the middle of the trip due to a bad bearing. No, it is the model.
Many of us have rented the same scooter from Gold. Battery lasts all day.
Real weight limit is 200 lbs. Mfg has a higher limit. I've heard at 250 lbs battery life is cut in half.
Gold uses, when available, extended batteries. Gold replaces scooters every 9 months.
This may a vendor issue.
