Marty Backe Posted December 26, 2016 Share Posted December 26, 2016 I ride them both a lot, but the ACM is still my go-to wheel of choice - it just handles so good. Now that the 1300wh 84v version is available it's tempting to upgrade. Link to comment Share on other sites More sharing options...
koto Posted December 27, 2016 Share Posted December 27, 2016 I prefer ACM since I drive it in a natural way. Msuper3 tends to keep vertical too early. Msuper3 is more difficult to manage at low speed. I cannot stay very stable at high speed on msuper3. ACM is more reactive. Msuper3 follows grooved surface while ACM behaves as expected.

LGJ Posted December 28, 2016 Share Posted December 28, 2016 Great info I use Kinsongs but need a bit more speed especially as they slow down when the battery gets lower, I also want bigger battery so was thinking which of these Gotways to go for, this helps and reminded me of an earlier wheel that had a wide tyre, that also went with the grooved serface.

Smoother Posted January 11, 2017 Share Posted January 11, 2017 The ACM seems to be a bit of a forgotten wheel, languishing in the shadow of the V3 and now the Monster. But you owners seem to hold it in high regard. its never really talked about, and on here, that can mean that it just works, period. Link to comment Share on other sites More sharing options...

Now that the 1300wh 84v version is available it's tempting to upgrade. I would wait a while..... The 1300wh Version seams to have the 2900mah cells (60cells on each side exactly like in the V3 1600wh)...there is also a Msuper V3 with 1300mah around now.... I would bet in one or two months you can also get a 1600wh ACM Version....because as i understand it they are just small on numbers with the 3500mah cells to put them in all their models... And as those 3500mah cells take the same place/room as the 2900mah cells, there is no reason not to have a 1600wh ACM also.... Link to comment Share on other sites More sharing options...

BTW, I just bought a 2200wh Monster, so I probably won't be buying another ACM anytime soon. Link to comment Share on other sites More sharing options...
nomad Posted January 12, 2017 Share Posted January 12, 2017 It would be interesting to know if they'll pack 1600Wh into the ACM later or if 1300Wh is already the max density / capacity. Just informed speculation or can someone confirm they are actually using worse cells? Link to comment Share on other sites More sharing options...

Just informed speculation or can someone confirm they are actually using worse cells? I dont know it 100% but as the ACM and V3 in the beginning both used the "flat" packs, which are now doubled...and have the same amount of space for batteries in normal config and so Need the "wider Shell" to double the packs.....there is no reason why it is not like i "speculated"... Also the V3 you can get now also with 1300wh...look at Speedyfeet.uk Normal: 20s6p = 74V * 3500mah * 6P = 1554wh == 1600wh "Light": 20s6p = 74V * 2900mah * 6P = 1287wh == 1300wh You can try that with One Parallel less for the 3500mah cells...and you end up with about 1300mah also...but as this Ends up with 5*20 cells...how will you split that on 2 sides? And how will you balance an uneven number of parallel Systems? I am pretty sure that are just the cells that are normally used in the 680wh V3......which are by the way not "worse"...just a bit less range. https://www.speedyfeet.co.uk/collections/gotway-unicycles But who knows if there will be ever a 1600wh ACM Version....as they use the better ones now also in the massive Monster?

nomad Posted January 12, 2017 Share Posted January 12, 2017 @KingSong69 Ok thanks for the extra info, it does make sense with the 1300Wh Msuper.. I didn't know the ACM had the same battery config. (If I understand it correctly with 4 packs of 24 cells it could be about 1300Wh?). It's most likely the same 6 packs as you say! If the capacity is lower with no benefit like higher discharge ability then IMO the cells are worse, except for budget.. I agree it's worth to wait in this case.

If the capacity is lower with no benefit like higher discharge ability then IMO the cells are worse, except for budget.. I agree it's worth to wait in this case. Nope, 24cells are not in the game..... On the 67 Volt System you normally have 32cells on each side of the Shell.....thats 340/410wh on a 16s2p (on one side!!!) config depending on 2900/3500mah cell.... =680/820 at all with 16s4p On a 84 cell System you have 60 cells on each side .....thats 643/777wh on a 20s3P (on ONE side!!!!) config depending on 2900/3500mah cell.... = 1300/1600 at all with 20s6p Correct way to calculate: 67,2 Volt: 16cells * 3,7 Volt * 2900mah = 171wh * 4 Paralell = 684wh = 680 67,2 Volt: 16cells * 3,7 Volt * 3500mah = 207wh * 4 Paralell = 814wh = 820 84Volt: 20cells * 3,7 Volt * 2900mah = 214wh * 6 Paralell = 1287wh = 1300 84Volt: 20cells * 3,7 Volt * 3500mah = 259wh * 6 Paralell = 1554wh = 1600 For some interest to the new GT16 by Rockwheel: They claim 858wh on their 84 Volt System and have said it is a 20s4P System 20cells * 3,7 Volt * 2900mah = 214wh *4 Paralell = 858wh!!!! So here also the Producer did not get the most strongest batteries available....and here in this case it is no "speculation" as i saw the used batteries in production line! and montage With the better cells they could have brought the Watthours on the GT16 up to 1036wh!!! But unfortunatly they didn't.... Seams they all run low on the 3500mah cells (or to expensive).....and please dont get fooled of Statements when they say that the 2900ers are "higher Quality" cells....they are in the same amperage capable league as the 3500ers.....

nomad Posted January 12, 2017 Share Posted January 12, 2017 If the voltage per cell is the same, and I now understand it always is, then it would be 101V for a 24-pack.. So I get it that this being an 84V wheel it must have 20 cells per pack then.. I used an online mAh to Wh converter and got the same numbers as posted above: Each 2900mAh cell at 3.7V give 10.73Wh so: 16 cells (67.2V) = 172Wh pack >> 20 cells (84V) = 215Wh pack << 24 cells (101V) = 258Wh pack Each 3500mAh cell at 3.7V give 12.95Wh so: 16 cells (67.2V) = 207Wh pack >> 20 cells (84V) = 259Wh pack << 24 cells (101V) = 311Wh pack @KingSong69 agreed, this 1300Wh ACM must have six 20-packs of 2900 mAh cells. And later they should release a version with 3500mAh cells! (only other option seems to be five 20-packs of 3500mAh cells it's too unlikely..)

nomad Posted January 18, 2017 Share Posted January 18, 2017 This russian shop came up in a search looks like they have the 1600Wh ACM already in stock: https://translate.google.com/translate?u=https://russegway.ru/index.php%3Froute%3Dproduct/product%26product_id%3D818 Link to comment Share on other sites More sharing options...
