Gene Martin Posted January 14, 2020 Share Posted January 14, 2020 Just curious about the physical differences between a 100V motor and an 84V motor. Winding wire size? Number of coils? Could you use a 100V motor with an 84 volt control board? What about a 100V control with an 84V motor? I am sure the control boards are voltage specific, but are the motors also? 1 Quote Link to comment Share on other sites More sharing options...
Popular Post meepmeepmayer Posted January 14, 2020 Popular Post Share Posted January 14, 2020 (edited) Exact same motor. Just driven at different voltages. For example, the 84V and 100V Monster, MSX, Nikola use exactly the same motor, the one motor Gotway uses for all their current 16 inch and bigger wheels (not sure if the Tesla motor is the same or an older revision of their "one" motor). Older 84V EUCs had ebike motors that had 60V printed on them. So motors do not need to be voltage-specific. In the end, it's just a hunk of metal that gets connected to a power source. As long as nothing melts or fries, it works. Edited January 14, 2020 by meepmeepmayer 8 Quote Link to comment Share on other sites More sharing options...

meepmeepmayer Posted January 14, 2020 Share Posted January 14, 2020 Sure In addition, as the battery gets empty, the voltage it provides decreases from its maximum (e.g. 84V) to its minimum which is like 25% lower (e.g. 66V or 60V for a "84V" wheel). So a "fixed" voltage doesn't exist anyways. Quote Link to comment Share on other sites More sharing options...

Not worth it. You would need a new board and new batteries* (buying batteries separately is almost as expensive as buying the entire wheel). Selling the 84V and buying a 100V makes much more sense because it saves you a lot of money and work. *update because of thread revival: you can mod a 84V battery into a 100V battery if you absolutely want, but it's still a lot of work and you still need a new 100V board.

As I understand it, it seems to be the same controller board. So yes, by changing out the (3) 20S3P batteries with (2) 24S3P batteries, you should be good. Correction (see below): You'd also have to change out the mainboard. I should have looked into it even further, because it is indeed a different board as @Planemo and @meepmeepmayer state.

Planemo Posted April 28, 2020 Share Posted April 28, 2020 The boards are not the same at all. Look closer at the listing in the link you posted. I have converted my 84v msx to 100v. 3 Quote Link to comment Share on other sites More sharing options...

No, 100V and 84V are always different boards. 3 Quote Link to comment Share on other sites More sharing options...

Hello , i need to do the same , please can you telling me if something particular to do ? i received soon a 100V board and have already a 84 msx without board and batterie pack . I would test this borad with my MSP pack . Thank you for your help. Quote Link to comment Share on other sites More sharing options...
Planemo Posted June 2, 2020 Share Posted June 2, 2020 Not sure I understand. So you have a full 100v MSP battery setup to fit into what was an 84v msx? If so the only other thing you need to do is fit a 5 pin charge port. Well, you dont need to, but its doing the job properly. Quote Link to comment Share on other sites More sharing options...

A friend give me a msx84V without pedals and a dead mother board. I will convert this msx in 100v and use my msp battery to check if it works. Because I don't want buy pack for the msx it is to expansive and I don't found a good value aftermarket battery pack. My question is on the cable routing regarding a 100v and a 84 v board. Is it the same connectors? Do I need a specific things? People confirm 84v and 100v motors are the sales. This is my goal. Thank you for your quick reply I really appreciate. Have a good day Quote Link to comment Share on other sites More sharing options...
Planemo Posted June 4, 2020 Share Posted June 4, 2020 Depending on the manufacturing date of the board, some of the smaller plugs (led/front light/usb etc) moved positions on the board so you may need to extend one or two of them. I think I had to do one. Not a big deal. Overall battery/charging/motor wiring layout is the same. If you are using MSP battery packs (21700?) you would also need the wider MSP side panels no?

Yes i will try only one side pack to test if the wheel is operational Do you know where we can find a wiring layout ? regarding boards? thank you Quote Link to comment Share on other sites More sharing options...
