I disagree with Wheel Good Time opinion piece, that is, Inmotion is somehow evil, and is undermining its customers by offering swappable batteries. Inmotion is actually doing the opposite. It is actually a great thing that Inmotion has put in the technology to deal with battery packs that have different voltages when they are connected together in parallel. And a practical way to reduce price of entry for new wheels for some of its customers whose situations allow them buy battery less Inmotion wheel. Should a customer need a wheel for off-road, and a wheel for on-road cruising, being able to share a single set of battery packs would be nice. I think Wheel Good Time is making a big assumption that Inmotion customers will be locked in. If a person like Inmotion wheels, then the swappable battery feature can save this person some money should he choose the battery-pack-less option. Otherwise, it is not that big a deal. If I buy an Inmotion wheel with swappable battery packs, the wheel I buy next after that may not be an Inmotion because a competitor's wheel may be better. Yes, it is certain a factor in the equation, but it isn't the only factor that will affect my buying decision. Moreover, battery cell technology advances are very fluid. Samsung 50S may enter scene soon for example. (This may not be trivial to some. The 50S is both a high discharge and high capacity cell.) Ditto with BMS's. With swappable battery packs, changes may come slower. So this potentially could be a negative. Electric wheel development is in it very early stages. Many areas in a wheel can change rapidly. Also, I can see swappable battery packs can influence a buying decision maybe for the first couple of years of their life. 4 Quote Link to comment Share on other sites More sharing options...

I also have several issues with that video. First of all… Walled garden, hard to leave. How does that not apply to Android OS as well? I recently helped my parents switch from Android to iPhone. Wheel Good Time thinks it was somehow easy…?? Or to switch to a Windows phone. Whether they still exist, I don’t know, but I doubt it is/was any easier. The thing that makes it hard to leave Apple is the OSs and the user experience that others simply aren’t able to offer. Inmotion is a bit alike in that regard. At least to me. And onto EUCs. If Inmotion offers a feature that others don’t, how’s that evil, unfair, or locking in? Other than to make the product more attractive than others. Based on the video, ALL current manufacturers should be considered evil, because they don’t offer swappable batteries with other manufacturers either. Or even altogether. Hands up if you can imagine Begode cooperating with Inmotion to use their battery packs on future Begode wheels…  Either they will disregard the option completely, or they will invent their own system. Which will be changed for each new wheel though… But the battery rental thing, I really don’t think it will catch on. The customer base is simply not nearly large enough for it to be beneficial for any company to store, maintain, and offer them for rent. 4 hours ago, techyiam said: If I buy an Inmotion wheel with swappable battery packs, the wheel I buy next after that may not be an Inmotion because a competitor's wheel may be better.

And it might be possible to update the BMS firmware in case the voltage would be different, but I don’t know if that’s the case with the V14.

There is more that voltage to consider. The way to you can put a load or draw out current and recharge it as you break is also something that can change from wheel to wheel. So to have a battery pack that can handle this and a bms that than keep this within the cell max load. So what at first seem simple might not be as simple to design a pack that works now and in the future with future requirements in mind. So for Inmotion to go in this direction is a huge development step as I see it. Yet another differentiator to other brands. Quote Link to comment Share on other sites More sharing options...
bpong Posted September 16, 2023 Share Posted September 16, 2023 (edited) About the "dark truth" video on swappable batteries... everyone is entitled to their opinion. No matter how misaligned it may be. I probably will end up getting a V14 and swappable batteries is one of the reasons for the purchase. Wheel good time and Dark truth is a farce ... its a blatant attempt at fear mongering with limited understanding of marketing terms and buzz words. its no different than the crap that the QAnon were feeding their blind followers... pizza any body ?!?!? its just an electric unicycle, geezzzzz, ... and its damn fun owning and riding one. its hard enough wading thru all the new innovations and specs of the new models coming out recently - why add more confusion to our fav pastime ? standardized battery formats ? AAA, AA, C, D, 14500, 18650, 21700, lithium, NiMH, LiFePO4, and the venerable Alkaline battery (Duracell), etc,... all globally available, all over the world. and no conspiracy associated with them.

Most BMS limit peak current that can be drawn from the battery as well as peak charging current. This should be tunable in smart BMS firmware, but boards that can handle higher current cost more. Say you have 4p 50E battery pack. Max battery current should be 10A x 4 = 40A. When building a pack with 50S, that can be increased to 25A x 4 = 100A Quote Link to comment Share on other sites More sharing options...

This way I will have 2 functioning wheels to choose every day instead of just one, but I suppose many people will still want to save money by buying new EUC without batteries and taking them from an older EUC. It would be really cool if Inmotion starts selling their batteries, controllers and motors to other manufacturers and like in the bicycle or ebike world new smaller brands can emerge taking advantage of proven technology, creating their own vision of the best EUC, without having to make everything from scratch. haha 🫣🙄😂 (quote from the video): "and then you can rent those batteries wherever your destination is" thats not going to happen the next 10 years, or in fact never.

But its funny😂 Another thing this is not going to happen as 170+ passagerer airlines signed an agreement to ban all pve on passagerer planes with out without battery pack matters not. My guess is to avoid discussions at checking and the risk of battery not being removed and it being missed at checking. Yes you can ship by freight planes but that will cost a fair bit of money too. Now one thing I can see this being good for is if you have to ship off a battery pack for service og that you could ship only the wheel as battery pack are both adding weight and class it as high risk freight. It doesn't solve everything but it do add more flexibility to some situations. And should you have a cell problem then it is possible to disconnect that pack and still ride because the wheel is designer to cope with this. Might not be able to push as aggressive. Kinda like you have limited speed/range as a spare tire to a car to save space. That said you could play with the thought of having half battery packs to make for factor slimmer and lighter. Like I said before I view this as innovation and yes it will come at a cost yet this is okey in my view. Quote Link to comment Share on other sites More sharing options...

I have not seen it myself yet. But as I understand the hint given long time back when I had deeper contact with Inmotion my guess would be it is how battery packs are build and their bms together with the raptor board and firmware. It is not just two wires going into same connector. 1 Quote Link to comment Share on other sites More sharing options...

There’s a separate electronic circuit that controls the battery connections through mosfets similar to what we have on the motor controller output. Most probably the packs with a lower voltage just will not be used until the others get down to it’s voltage.  The V11 already has something similar, although while the packs aren’t hardwired either, it’s not designed to be ridden with packs of largely different voltage and will lock up the wheel if the difference is too big.

meepmeepmayer Posted September 19, 2023 Share Posted September 19, 2023 This isn't exactly new, but it deserves being stated: ewheels sells the Adventure for $3300, and on EUCSale it's 3400€. That seems to be the regular price in $ or €. Quote Link to comment Share on other sites More sharing options...
