EUC 0% battery voltage for various models

[RagingGrandpa]

For future reference:

"Tiltback voltage" is a misleading term, because many EUC's begin tiltback as a function of voltage and speed. So here, 0% means "when the EUC will not move at all without severe tiltback"

I think these numbers are right- any criticisms? 
Info for other models appreciated, thx.

Damn! The 18XL goes to 3.00v. Bold!

[meepmeepmayer]

Where do these numbers come from? You measured something, or just the "official" (as official as information we can get) 0% voltage?

Earlier Gotways (18650 etc.) all use 3.3V, unless there is an exception I don't know about.

16X: 3.15V

V11: @mrelwoodsays it is 3.15V too

V12: ???

[Freestyler]

Data from latest black controller and firmwares.

Rumor is that begode is releasing new firmwares that will allow lower discharge.

[Bizra6ot]

@RagingGrandpa Begode wheels from examining the latest firmwares by @Freestyler

https://github.com/freestyl3r/euc-dash/blob/main/js/begode.js#L7-L23

 

I can confirm that my Exn with black board started low voltage beeps below 78V

Yup, aggregating from various threads there in the forum, since many of us want to know how to set the EUC World custom battery levels precisely.

Thanks!

All added now.

... and I think the 'tiltback at 1mph' happens around 75.6V? 

[EMA]

@RagingGrandpa you can add commander tiltback at 74v

 

Begode future firmware will be 72v tilt for all wheels and low voltage alarm at 80v

[EMA]

forgot Master 104v

Yes 75.6V tilt back & 78V low V beeps

Edit, last one is 72V tilt back & 79V low V beeps

I had read somewhere that the Sherman cutoff voltage was lower with the newest firmware release. I haven't tested that myself yet; do you have any data that clarifies whether or not that is accurate?

Upcoming EUC World update will include improved battery level indications for various Begode wheels

[RagingGrandpa]

So has anyone discovered the 0% voltage for Kingsong S22?

And, did a 3.0V/cell Gotway firmware finally emerge?

Thx

Wow... I presume this would require reflash of 2022 firmware, which is not possible on many pre-2021 controllers?

[Freestyler]

Yeap, if it's not reporting a firmware version on euc dash (usually green controllers) then you are out of luck.

(Personally I wouldn't be eager to ride a wheel at 3v)

S22 goes below 3v cell

 

well below

 

im unsure of what the % the wheel was reporting at this point but I’m told it was still rideable 

 

 

[MexicanBatman]

Well this is interesting 

 

 

[meepmeepmayer]

2.5V? 

[EMA]

personally i'm fine with a 0% at 3v but i don't like at all going below that, maybe another s22 bug

Edited September 9, 2022 by EMA

[Planemo]

Going below 3v might be fine for a flashlight but it's madness for a self balancing vehicle that needs *large and immediate power demands*!

Very surprised that KS of all people would do this.

Edit: *even at low speeds*

Edited September 9, 2022 by Planemo

[MexicanBatman]

Not my S22

 

and bothe the phots I’ve posted are different wheels

 

the first sub 3v wasn’t ridden till flat

 

the 2nd one was ridden till it literally cut off and the rider bailed

 

however it’s madness!
