It is so tempting to call it bullshit on every slide. Well, there are clips of a video of someone riding an ET Max coming out of Hong Kong. If I were to take the pessimistic view, I would say it is a next generation, 168 V Master based on the Extreme chassis, as opposed to the EX30 chassis. And that I am not expecting much from the suspension. EDIT: Oops, someone beat me to it. 1 Quote Link to comment Share on other sites More sharing options...

I heard it first from Chance Hinz, who's had insider info on these things. Here's the response I got (below). As you know. Sometimes the initial numbers aren't accurate - remember how the extreme was originally supposed to be 77 lbs? Turned out to be a fair bit more than that. Honestly I doubt it'd be less than 99 lbs if it has metal battery boxes, a 4500w motor and 3000wh batteries. 1 Quote Link to comment Share on other sites More sharing options...

Ah, alright, yes at least it seems unlikely that it would be lighter than the Master V4 which is 42kg's. Quote Link to comment Share on other sites More sharing options...

Popular Post Jason McNeil Posted January 8 Author Popular Post Share Posted January 8 (edited) On the tire front: BG claims that tubeless doesn't work on the ET Max rim, have requested that they test this regardless—since the rim casting is of fairly high quality, I don't see a good reason why this won't work. Sourced a couple tire for independent testing, the CST-6501 tubless & a couple different sizes of the Maxxis S98 ST, those are tubeless as well. Another slick tire, similar to the 6501 is the C922, but not in stock.... Edited January 8 by Jason McNeil 5 Quote Link to comment Share on other sites More sharing options...
YCC Posted January 9 Share Posted January 9 (edited) Is it possible for a wheel of 3600WH battery with 168 charging voltage? 40 batteries * 3.75 nominal voltage * 5 AH(21700, 50E) * 4 package =3000WH Therefore, we could have 750WH per package of battery with 168 charging voltage, and it is possible for choice of 3000WH, 3750WH, 4500WH battery capacity with 168 charging voltage.

BleepBloopBlop Posted January 9 Share Posted January 9 Not with 5ah 2170 cells. You are looking at ~750wh per 40 series bank. So we are looking at 750, 1500, 2250, 3000, 3750, 4500wh. Typically Begode does 2-4-6-8 parallel so the next logical step up from 3000wh is 4500wh and then 6000wh. 1 1 Quote Link to comment Share on other sites More sharing options...

Maybe higher voltage is possible for 3600WH capacity. For example, 900WH package of 48 batteries with 5AH 21700 cells is able to compose 3600WH capacity, however, the charging voltage would be 201.6V(48*4.2).

I did once array of 100 aliexpress caps in parallel to get the crazy capacity to jumpstart the car - but it survived just two cycles. Can we find label of cap ?

You could also use a 40S8P arrangement with 3ah 18650 cells to get 3600wh but I doubt begode will go there as they don't produce any wheels with 18650 cells any longer. 1 Quote Link to comment Share on other sites More sharing options...

Begode boasted 20 capacitors on the ET Max controller in their launch video. Not sure why Begode went in a new direction on capacitors in their new controller. Begode had been using fewer capacitors but of larger capacitance in the past. The contention in question is why we only see 19 capacitors instead of the claimed 20 in the launch video.

Same place for buttons and charge port. (Extreme Pro) Don't know what to say about that plastic seat. One big drop sideways on a rock or concrete and gone is your water resistance. Also why give up the included seat philosophy... Rest looks sturdy to me. Quote Link to comment Share on other sites More sharing options...

I bet it's just whatever is on special at the factory. If the smaller caps are cheaper per farad then the bigger ones - well, just swap'em all out ;P It's a fairly pointless metric, the marginal gains of more caps are going to be pretty minimal.

alcatraz Posted January 12 Share Posted January 12 I saw somewhere that caps in serial provide higher voltage resistance. Like two 30v caps in series can handle 50v. Is that what they're doing? Quote Link to comment Share on other sites More sharing options...

Or use 40s 8p with 2170 50s cells. That gives you just under 6000wh with 30kw continuous (5c). That’s the same layout as the Master Pro, but with slightly taller packs with more voltage. This is basically the max you can fit on a large wheel (17”+ rim). Not really possible on a 20” wheel though because the pack will extend past the rim towards the bottom.
