Default Flying the unfriendly sky's on United

Another bad decision made by someone trying to fly the friendly skies on United. I've not flown with my Segway MiniPro yet, I've always flown with my P133's. I too use my Segway's for personal mobility. Has anyone else here flown with a MiniPro? Here's the article reporting the experience this Segway user had while flying on United.

I'm not sure why you call this a bad decision by the flyer. Are you referring to the decision to use United in the first place? The incident itself was clearly United's fault.

I wonder if TSA and United Special Needs desk thought the mini pro was a full size Segway P133 without lithium batteries.

Then United staff sees someone arrive with a hoverboard clone/variant (hub motor wheels, 18650 lithium batteries, cheap) and says no way. With the disconnect of department polices for all these tech toys, United looses in the court of public opinion.

There is a kid online that damaged his mini pro's batteries and replaced them with new cells. They are just laptop cells. He had a local electronics guy toss the 2800mah stock cells and replace with no name brand 3200mah cells. It gave him a 20+ mile range. Now days airlines can't even tell what batteries are in mini pros.

I would be surprised if the mini-Pro isn't using 18650 form factor batteries - They're pretty much the industry standard. 92 of them in each Segway battery (184 of them in total) and the Tesla Model S is also powered with them - More than 7,500 of them in the Tesla pack

At 184 cells per big Segway, switching to regular LG MG1 series batteries (from the expensive proprietary batteries) would be $600ish just for the batteries. Then you would need the nickle strips and weld them yourself. Any opened battery being banned from aircraft.

Battery guys hunt wrecked electric cars to salvage those cells. Hybrid cars are also handy. I wonder what process is used to economically connect 7,500 cells.

I did notice that the passenger in the article didn't complain or seem to have much of an issue with United's response. He was probably expecting not to be able to take the mini pro. The article writer had more of an hissy. Exciting article on a trending subject (United) to bring in audience numbers to a website facing stiff competition?

You can't fly with Segway batteries even if they are sealed. The FAA prohibits carrying any form of lithium ion battery larger than 160 watt hours

https://www.faa.gov/about/initiative...info/?hazmat=7

A single Segway battery is about 385 watt hours

The Tesla batteries are contained in individual modules consisting of 444 Panasonic 18650 cells of about 3400 mAh nominal capacity. The cells are configured 6s74p, Voltage range for each module is about 24.9V at 100% SOC for a capacity of 250Ah, 5.3kWh. The cathodes are welded to a tube to enable them to be liquid cooled. Most people using them for home solar purposes buy however many modules they need and use them in their OEM configuration

My Mitsubishi EV's use large 50 Ah cells, 88 of them in series for a 16 Kwh pack
