Wheel selection advice

Would be that double pack?

anyhow, can I get a bit more specs about throne you have?

- is it new?

- mileage approximate with this battery?

- weight with battery on?

- an extra battery,where could I get one if needle and how much does it weight?

a picture of it would be great :) 

sorry if sound weird :)

@Paul Panait No problem at all : 

  • Is it new? Yes
  • Mileage approximate with this battery? Gets the standard 10Wh/km, or around 17km max
  • Weight with battery on? 11kg
  • An extra battery,where could I get one if needle and how much does it weight? We will be bringing in the spares packs in about a month time. Same weight as the one that comes with it, 800gm.

Mobility aid = aids mobility = eWheel aids mobility. The point is that the removeable battery should technically fall into this category. King Song are also releasing an optional 155Wh pack specifically for airline compliance. 

British Airways is very specific: http://www.britishairways.com/cms/global/pdfs/lithium_battery.pdf. Segways are excluded from the "assistive devices", as are ebykes and similar devices. In most interpretations, mobility devices help people with limited mobility unaided. Hard to argue that a healthy person who can safely balance on a unicycle has limited mobility :P. You might get away in certain cases, but it's a risk. And once you can't take that battery with you, leaving it behind to be destroyed is pretty much the only option (hard to find a service in the airport that can handle big lipo shipments)

The new 155 Wh KingSong battery will nicely solve the problem, and two of those can safely be carried onboard any airline, finally solving the problem once and for all

Got to agree with @robca here. I wouldn't try bringing a battery over 160Wh on the plane unless I had gotten written confirmation it was okay from the airline. (Specific rules vary by airline, the IATA only issues guidelines and an airline can be more restrictive but usually is not less.) I'd also bring printed copies of the IATA guidelines and documentation on the battery size in the unit.

Just need them to make a shell with two slots now so you can have a capable 310Wh of battery on tap.

@robca the document you're referring to is from May 2013, the one I referenced is much more recent, there's a bit of inconsistency between on other things, like there being no provision whatever for >160Wh in this older document. 

The beauty of the swappable battery thing, is you can have one for local use & a travel battery that has none of "can I?" "can't I" questions attached of the larger pack. In my opinion, I think the 174Wh swappable is possible under the current guidelines, but because there is a risk of complication, probably not worth testing it at the airport. Anyways, because of the modularity of the KS14B, you can do want you want as to travel.

Nitpicking, I know :), we are fundamentally saying the same thing. But the old document actually clearly says "(For batteries contained in Wheelchairs, please refer to Special Assistance on BA.com)". That, imho, means that there are exceptions for >160Wh only for wheelchairs (the document you refer to, those are complementary). Which makes sense: given that bigger lipos are truly dangerous and there is a long list of fires in flight, if I were to make an exception, I'd make it for people who could not absolutely be without the device (wheelchair users), not for recreational devices or drone flyers...

Also, on the definition of "mobility aids" @Jason McNeil I don't think you'll get very far with that argument. Many places seem to limit their use to people with actual mobility issues. Here are a couple I've found locally as I've been looking for places to ride:

National Zoo, Washington DC: http://nationalzoo.si.edu/Visit/parkrules.cfm

Power-driven mobility devices other than wheelchairs, such as scooters and Segways, may only be used by individuals with mobility disabilities. All such devices must be operated in a manner that does not compromise the safety of the user, Zoo visitors and staff, or Zoo buildings and grounds. Individuals operating power-driven mobility devices within the Zoo must remain in control at all times and must exercise caution. The Zoo requires users to operate their devices at a speed no greater than a walking pace of three (3) miles per hour.

An individual without a mobility impairment is not permitted to operate a power-driven mobility device within the Zoo except as part of an authorized activity.

An example of the last sentence would be a prearranged Segway tour.

Maryland National Capital Parks: http://www.mncppc.org/Assets/Commission/Notice+15-01.pdf

The operator of the device must be an individual with a mobility disability. M-NCPPC staff may request verification of such status in the form of a valid State-issued disability parking placard or other State-issued proof of disability that is issued in the name of the operator.

You can see similar wording for parks across the country: https://www.google.com/search?q=epamd+operator+must+be+disability&oq=epamd+operator+disability

I know right, literal meaning vs. modern euphemism for disability carriage. I think it's only a matter of time before the authorities like IATA recognize that there are good batteries from good manufacturers that are a million times safer than a couple LiPo's being carried around in a carry-on bag. At the moment both are considered equivalent, which is pretty crazy.

I'd liked to see manufacturers eventually install some sort of master battery cut-off switch, which physically removes the power to the control-board. 

In the perfect world, the battery pack would be wrapped in a fire-resistant sheath to contain, or at least minimize, the chances of the chain reaction & as Bryan suggested, 2x modular 32 cell pack slots on either side.

To all of you MANY THANKS. 

I have passed safely 2 airports: Copenhagen and stockholm. I'm happy about the EUC since is fulfilling MY needs. 

However I consider to get another with the biggest battery on the market and no shut downs, of course,  just to ride freely around Copenhagen. 

Just FYI the airline company is your reference point if you can take it on bord ot not, but at the end they can't have the final say since you can just put it on the ground and say " that thing is not coming with me" at check in counter. 

But the security team in the airport will have the final say ( the person at the scanner because they are certified and trained). When your EUC goes through the scanner they will count the cells and do the math if is fine or not -or at least try. 

We are safe to pass because the batteries are small cells and all connected in a safe in closure. So at the end if anything would go wrong ( God forbid) the person at the scanner will have the final responsability. But you'll have yours as well- I think. Hope to never find out. 

So bottom line more cells you have, smaller chances to pass through.
