I just talked to Rhonda, who learned a trick today. She was starting to go up a good incline but had to stop when someone walking in front of her. She started again, and got part of the way up and her battery overloaded. (This happens to protect the lithium ion battery from sustaining damage.)
With a little quick thinking she decided to stay on the scoot, turn it around and give it a hard push off with her feet to head back down the incline. The battery quickly turned from red to green.
She's sure it didn't look graceful, but it worked!
If you're concerned about this happening to you, you can always choose the sealed lead acid battery instead. It doesn't overload. I chose the lithium ion battery instead because it weighs 4 1/2 lbs instead of 20 lbs., it can be charged at any time without damaging the battery, and did I mention it only weighs 4 1/2 lbs?
