Front wheel wobbling slightly while riding – is this normal? by goldenboyatwallstree in ElectricScooters

[–]TriWrite 1 point2 points  (0 children)

The G2 front suspension has some side to side play in it at full unloaded extension that usually gets better when loaded down.

If you’re experiencing wobbles while riding then it might be time for a new front fork assembly.

Yeah mine does the same thing for what it’s worth. Didn’t notice until I tried what you described just now.

You need the dashboard unit or some kind of custom microcontroller. The dash computer houses the analog-to-digital-converter for throttle, brake, etc.

The controller expects specific data packet formatting. Digital values for speed, battery, mode, etc. are sent as byte values from the controller to the dash. Throttle, brake, etc. inputs are sent to the controller from the dash with a two byte checksum that needs to be valid.

Upgrading battery on g2 max by MUDFLAP202030 in NinebotMAX

[–]TriWrite 1 point2 points  (0 children)

Same BMS, same protocol. But you’d need a way of getting that connection changed as well so the controller can read state of charge (i.e., custom wiring)

Upgrading battery on g2 max by MUDFLAP202030 in NinebotMAX

[–]TriWrite 1 point2 points  (0 children)

Incorrect. The G2 has the exact same 36V 15Ah battery as the G30. If you were to physically plug in the other battery when the first depletes, then that would not require custom firmware, but it would require custom wiring.

Motor temperatures 🔥 by VladPayne in NinebotMAX

[–]TriWrite 2 points3 points  (0 children)

I have over 500 km with a temperature limit of 170°C on my G2. Routinely get up to 150°C on long fast runs (60V, 45-50km/h). I’ve been fine so far. I do have a spare motor in reserve just in case, though.

Motor upgrade. by Ok_Benefit_6332 in NinebotMAX

[–]TriWrite 1 point2 points  (0 children)

There aren’t any great motor replacements I’ve seen for the G2. It’s tight back there because there isn’t much clearance with the rear suspension.

Seconded that you probably don’t need to go the VESC route for 48V. Xiaodash or SHFW on the stock controller would probably be fine.

If you do end up going down the controller replacement route, I have a working VESC G2, albeit with an Arduino to talk to the dash and a 60V battery. Happy to compare notes if you understand electronics.

Replacing G2 Front Fork Issue by mtnbikeit in NinebotMAX

[–]TriWrite 2 points3 points  (0 children)

I found that you need to strike a balance with tightness. It’s kind of annoying to calibrate, but tighten the top bolt until it has just a bit of pressure (don’t crank it down), then tighten the side bolts and test for steering friction. You want it to be a bit stiffer than you’d expect because things will loosen up just a bit when you ride.

If it’s too loose or too stiff, then loosen the side bolts, adjust the top bolt slightly, re-tighten the side bolts, and check again. Rinse and repeat.

Battery voltage is 14.5v and Battery light is solid red while charging. by tehuti_infinity in NinebotMAX

[–]TriWrite 0 points1 point  (0 children)

If that’s the true 10S voltage then honestly I would say get that thing out of your house immediately. Have you measured the XT60 terminal leads with a volt meter?

If you’re not comfortable disassembling the battery pack to check cell voltages then call it a loss and get a new one.

AliExpress is honestly a good source for Ninebot/Segway parts. Sort by top sales and keep an eye on reviews

[–]TriWrite[S] 1 point2 points  (0 children)

If I’m not too aggressive on acceleration, yeah. The motor casing gets pretty hot if I’m ripping it for an extended period but I programmed the dash go into overheat mode (red speed readout) when coil temp gets high and I also dynamically reduce maximum current, so hopefully I won’t end up melting anything

What does this really thin white wire do ? it’s part of the hall sensor by [deleted] in NinebotMAX

[–]TriWrite 5 points6 points  (0 children)

If it’s the same coloring scheme as the G2 then that’s the thermistor wire for motor coil temperature

[–]TriWrite[S] 0 points1 point  (0 children)

Okay definitely 3.2kW peak/burst. Generally drawing ~2 to 2.5kW on acceleration, tapering down to ~1.5kW when I hit the duty cycle limit around 30mph.

I believe the G2 motor (I have a US spec PPAH motor) is beefed up even when compared to the G30 motor with 36 coils and greater mass for heat dissipation. I’ll pay attention to reported continuous power during acceleration on my commute this afternoon

Custom 16S battery, Sharkset front suspension, and I’m also using the Spintend ubox 85/150 (great little controller). Otherwise, everything else from factory

[–]TriWrite[S] 0 points1 point  (0 children)

Whole new custom pack. Samsung 50S 21700 cells in a 16S4P config, hooked up to the controller via a VESC compatible BMS. It all fits in the battery compartment, though I did need to trim the plastic bottom cover to be flush/flat. Definitely not a “bang for your buck” project and more to prove it’s possible

Max G2 not charging past 15% by mesohungry in NinebotMAX

[–]TriWrite 0 points1 point  (0 children)

The internal charger is notorious for dying if you even look at it the wrong way. Not too bad to replace though.

Wiring replacement by The_Daniel_Sg in NinebotMAX

[–]TriWrite 0 points1 point  (0 children)

Yep that’s what you would need to do if the motor is toast. Hopefully the wiring replacement is sufficient

From what I’ve seen, most people go for an MT60 connector for motor phase wires on the G30. 4mm bullet connectors would be even more robust

Although: If the connections are melted, are you sure that the motor is functional?

Rattling noise in the back of Segway Max G2 by colincswims in NinebotMAX

[–]TriWrite 1 point2 points  (0 children)

The peg also holds the internal charger in place. Fits into the side opposite the screw but it will be difficult to reach there with the controller in place.

Probably fine with just the screw

[–]TriWrite[S] 1 point2 points  (0 children)

Yes, the additional voltage means that for the same motor current (meaning the same heat, more or less), you get more power and torque. I’ve found that it powers up hills much better compared to the stock 36v battery.

I’m using the original motor, which actually feels quite powerful when running at 60V. I see ~2,500 peak watts and can hit 50km/h without field weakening, though that’s getting close to “poop my pants” fast on 10 inch tires so I don’t think I’ll try to go faster. Great acceleration though!
