All this together can make sense if you print something like nylon.

And then, the butterfly 0.8 and 1 - somehow a bit too much

nylon is hefty whimsical plastic thoughNow there are modificationsless shrinkage ... but the bar for printing from / with nylon is not cheap, yes.

Another would be to understand that from this upgrade, and that tuning) For example, the protection of the rear light is an upgrade, i.e. what is desirable to deliver.

For example, the protection of the rear light is an upgrade, i.e. what is desirable to deliver.

It is desirable - it is undesirable personal business of each. As it turned out, the non-glued tires run well under normal pressure, and not all have a rear light, and not everyone needs a butterfly under the steering wheel. Everyone has different operating conditions. I like the protection of the ferry set because I am carelessly dragging the stairs in the subway and other different places, now this question does not soar me at all. Although you can safely do without it, but carefully use the subject.

[witbk]

Bylob I have time, I would muddle the controller with Ali on 500W36v for 650r + bms (without tricks for 10 cans) for 1500r, and the problem with disconnecting recuses will disappear, and the speed should also increase to 35. Can someone be a first researcher?

[macman74]

witbkThis is all without problems, just how can we connect all the blues and indications to our board? She will also have to change.

Here ishereI communicate with shamans who claim that the BMS xiaokata does not accept anyone else’s cans of 18650, that the capacity of the battery and other seemingly nonsense sewn into the controller. Waiting for a response from those who saw it with their own eyes, for only this strange fact keeps me from buying 50 cans of 3500 mAh for replacing our relatives)

In the future, I plan to shove the steering wheel cans 5 18650 and bring out the connector

and also start charging these cans to the syakat charging connector: rolleyes: only if you put them in sequence, you will have to charge the charge controller ...

[Metalfan]

I decided to transfer the message from the main branch here. I was interested in the subject with the protection of the brain of syokat from voltage surges during braking. Mole burn brains or knocks fuse ...
In the main branch, they referred to a certain fee of a certain comrade who smoothes out harmful pulsations ... there was an interest, what is there for a protection fee and can it be repeated "at home"?

macman74 @ 08.06.17, 14:23

Look at his youtube channel MINI. Demonstration of work even with an oscillograph))

Rummaged on his channel (it's about him?), Founda kind of video demonstrating the voltage waveform before and after installing the "protection", but essentially nothing is said in the video ...

Accordingly, the question is, nobody was interested in this?

[macman74]

MetalFan @ 06/09/17, 10:49

and also start charging these cans to the charging connector of the syokat only if you put them in sequence, you will have to charge the charge controller ...

This will not work. From charging syokata comes 42V, and to charge a power bank you need 5V. Although you can make a lowering scarf ... Banks are placed in parallel, at least 6 pieces (they fit into the steering wheel), and you put the BMS into them from the same bank in the steering wheel and that's all.

[ale-nikole]

For a long time I already took a 12k pitch on Ali for this, well, also for the gps trackerTyts. Now I wait for a connector - converterusb
I will put everything together with the protected 4-pin power connector (2 per charge, 2 per external batka). And I will fence it all (together with the contacts piping) at the end of the season, I still save the guarantee of Ekodrift, otherwise it will be enough, the controller will die of rekupa.

Here I communicate with the shamans who claim that the BMS xiaokata does not accept foreign cans 18650, that the controller has a capacity (!) Of batteries and other seemingly nonsense. Waiting for a response from those who saw it with their own eyes, for only this strange fact keeps me from buying 50 cans of 3500 mAh for replacing our relatives)

I also think that it is unlikely that the capacity of the cans is protection in a BMS or controller, since This value is non-constant. Limiting the capacity from above is theoretically possible, but also unlikely, because it is aerobatics, and the scooter has more ridiculous bugs in the form of a BMS knockout fuse. It turns out to protect defended above the roof, and the implementation is lame. In general, I also consider this a conscious rumor, thrown by the merchants, so that the type without them is nowhere :). Can go the other way?) Immediately do not buy a bunch of cans, and try to skolhozit assembly of 10 cells of the cheapest batteries at 3.7V, slip them into the BMS and try to turn on the scooter. The experiment is inexpensive, you can risk it). You can even throw off on such entertainment).

[macman74]

sergsap,That's it)) I also came to the idea of ​​such an experiment. Its cost is only 2-3 rubles, and then banks can be sold, if that. You do not even need to weld them - fasten the contacts of the wires to the BMS with banks of neodymium magnets, attach the plug and its BMS board instead of the drain battery. Here are just a connector on it some strange, non-standard.

Only strains the moment with the loss of warranty (

PS: I found where to buy 10 cans of similar stock for just 2100. When I find a suitable BMS battery connector for the drain, I will start the test assembly.

Hello! After 400 km. began rattling rear bog a la "ruler on the edge of the desk." An autopsy revealed cracks in 2 out of 3 plastic mounts:

There is no sense in gluing / pouring / restoring broken ones - anyway, they will be broken up again on patchy coatings.

The solution is more than trivial: long bolts, spacers, washers, grinding, painting.

Interestingly, a soft plastic lining would help ...

[GuestWho]

It turns out that it is really better to make the wire to the tail light from the wheel axis (like on a bicycle) - at once two birds with one stone - fastening the wing and protecting the wire of the lamp ...

[Metalfan]

By the way, yes, MSK, if anyone needs printed wire protection - contact - print.

[AlteroAscension]

There was an idea to make a switch of maximum speed when triggering to the floor. Because Often, on the way to work, and in general I drive through very uneven asphalt pavements, and keep the trigger on a small value of gas, shaking over bumps ... such is my occupation. Eco mode is not suitable due to the low engine power in this mode.
Technical details:
In the trigger an ordinary Hall sensor, power + 5V. output 0.8-4.0V (respectively, pressed and fully pressed the trigger)
At first I tried to put a resistive divider at the output from the sensor, but with the gas released, the minimum voltage after the divider is less than the prescribed 0.8V. The scooter starts beeping, reporting a sensor break ...
Without hesitation, I decided to go the other way and use a microcontroller.
I shot a video about this:tyts.
If this topic is interesting to someone or there are more ideas - write, discuss. Perhaps I will make a small batch of regulators then)

Eco mode is not suitable due to the low engine power in this mode.

Is in eco-mode is not limited only to the maximum level of engine power of 400 W (stnadart 500 W) when the trigger to the floor? You also need the average position of the trigger, approximately, with the standard mode, which in my opinion gives the same power, which is about 2/3 of the trigger with eco-mode. Is not it so?

[AlteroAscension]

macman74,
Less there is 400 watts in my opinion, I'll check it tomorrow. But from practice I know that in eco he does not even go on small ramps on ramps.
And sometimes it is necessary to go very slowly in the crowd or when someone is walking nearby, they generally need 5-6km / h.
So do the modes. Assume a long hold - 6 km / h, short - 15 km / h. Any press in this mode - the transition to the standard. In this case, depending on the mode, the LED of the corresponding color lights up.
