I have Superhandy scooter that I love. AmazonLink.

It has swappable batteries that weigh about a pound and a half. They go 6 mile flat out or 3 hours stop and go. It comes with two. I own five. I can go for 15 hours without recharging. It charges externally, and I have multiple chargers. Each battery charges in one hour.

Edit the scooter is 35 pounds or 25 if you take off the seat first, and the batteries cost $130 new, but I’ve been getting them from Amazon for a lot less than that. That’s also where I got my extra chargers.
