Popular Post Jean eRide.ie Community Posted October 1, 2019 Popular Post Share Posted October 1, 2019 (edited) 12 hours ago, Jean Dublin said: Someone on Facebook called "Way Chic" (not sure if that's Chicway, or not...) has been advising people not to buy 3108wh and to buy 2460wh instead, because 21700 batteries are used/second hand, from electric cars. Gotway confirmed that is not true, that they are brand new. Probably that seller just wants to get rid of the stock, or just keep selling more by telling people not to buy the only option with bigger battery. No idea... I know what the source is now... Chicway.Shop / Green Fashion (on Aliexpress) is lying about the 21700 batteries, saying they are bad, because they don't have them, and can't get them in stock yet... Gotway isn't selling to them anymore, they are buying the GW wheels from someone else, who is buying from GW... So when he's saying "wait until 21700 is mass produced and new ones are used by GW", he probably means "wait until I have them in stock and can sell them myself to you"... And he's telling people to buy the "safer" Nikola 18650 and the Monster 18650 2460wh modded by the shop/seller... (one arrived burned, remember?) So that may stop some people from buying the 21700, and get them to buy it from him once "they are safer" 🙄 GW isn't letting anyone buy anything anymore Who told me all this, is also in the industry, and can't get 21700 from GW either, for now. Here screenshot of what two friend of mine were told by Way Chic on Facebook Messenger (ChicWay). One wanted to buy Nikola 21700 100v 1800wh, the other wanted Monster v3 21700 100v 3108wh.

If a resellers insinuates GW such practices, one could come to the idea, that resellers do such things, too (selling reused batteries as new...). Anyhow it leaves a bad taste of the reseller - why does he continue selling products of a company doing such things! How could one be sure it does not happen with 18650 cells, too? Here where not really a considerable amount (?if any at all?) reports till now of bad battery packs in new wheels? Just seldom reports of single cell (pairs) going bad (?a bit?) too early - I'd account these incidents to bad cell matching/manufacturing mishaps? 2 Quote Link to comment Share on other sites More sharing options...
El-Rudio75 Posted October 1, 2019 Author Share Posted October 1, 2019 Moreover, I do not understand why Greenfashion all of a sudden raised prices, esp. 100v Nik. now. €2980??🤔 Quote Link to comment Share on other sites More sharing options...

Thanks for the info, so I guess what burned the inside was just the wheel trying to spin, but being blocked. I decided I'll buy the 3108wh, as soon as I sell the 1845wh, I just put it up for sale. I'll definitely ask them to protect the power button from accidental turn on... before shipping it. Also, whoever has the tool/part needed to fix the loose axle bolt, have it ready for me haha. Hopefully it won't be needed... Edited October 2, 2019 by Jean Dublin 1 Quote Link to comment Share on other sites More sharing options...

Very curious about the charging time and the milage you can get out of it, as well as the internals. Will you test and show us once its in your hands? Keep us posted! When will you expect it?

Jean eRide.ie Community Posted October 13, 2019 Share Posted October 13, 2019 I'm also looking at using a 100.8v 10A charger, otherwise the 3108wh would take forever to recharge on a +200km long trip with one break. I read before in this forum or the French one that GX16-5 has its limits... So I asked a chargers seller. I shared the answer here, let's see how this turns out.

It’s a simple modification to make the Monster (or any Gotway 100V wheel) take 10A. Simply run 4 pins/wires (+12-45) to an XT30 male and use 18AWG silicone stranded (instead of the stock 20AWG) to be able to support 10A. You’d need to modify the 10A charger as well to the aforementioned pin configuration. The +1 -5 configuration can probably at most push 7A without significant heat build-up. I did a range test comparing the 2460Wh Monster to the 2200Wh MSX, and it seemed to be as expected, 35 miles with 30% remaining vs 38 miles with 22% remaining for the MSX, traveling at an average speed of 30 MPH.

Popular Post meepmeepmayer Posted December 15, 2019 Popular Post Share Posted December 15, 2019 @Jean Dublin Good info. Wow what a disappointment this mod build is! You hope the (Chinese) sellers do what the (Chinese) manufacturers don't... and then you are reminded they're Chinese after all If you want a better built extra pack, get one from 1radwerkstatt.de. Costs extra, but maybe in the long term that's better. Looks like this 3108Wh 100V Monster build should be avoided. Too bad. 4 Quote Link to comment Share on other sites More sharing options...

Only about half of the battery works on mine. A few others also bought it. I noticed Jerry Fung in New York, with similar weather, was getting about double the range than me. It seems like he was more lucky than me. Also, I had the Monster V2 100v 1845wh before, so I also noticed I got less range than before... Measuring voltage, the result is 100v on the app and charging port. Also 100v on the battery packs. Voltage test, all good. Measuring Energy use by the charger with a smart plug, energy meter, I saw that it only used 1150wh to charge from 25% to 100% Next, test the separate battery backs, individually, to power the unicycle, or to test if they take charge. Test Failed for the custom pack. Not powering the unicycle, not charging. Then we remove the blue wrap from the battery that's not working, to find a very poorly built battery, with the cheapest component and not properly welded, 4 cells are not even welded and are dead with 0.25v! This is why I can't recommend anyone to buy this 3108wh modified Monster. I'll get mine repaired with spare parts I'll get from the seller, I've to stick with it after such an investment on it. In the meantime, riding it with only about 1500-1600wh battery (well, same as before, but with less weight). The BMS is the cheapest available, the cells have no name, no brand, no specs written on them. Thanks to @US69 for his help via WhatsApp. jerry’s range wasn’t all that amazing to begin with considering i saw he got 61 miles not really riding that wheel hard. I ride my wheel like a bat out of hell and can get 50 miles to 20% battery worst case out of my 2460Wh Monster. I did a 38 mile ride not long ago in the cold SUSTAINING 30+ MPH on a highway service road over 21 miles with no stops and still had 38% battery left. Thanks for the PSA! edit- I realized how dangerous this is after looking at the photos. if the disconnected nickel strips somehow touch during a bump or something, there would be a huge surge of power if the voltage difference is significant thus possibly causing fire. Glad you picked this off quickly and I would urge everyone who buys this wheel to do a full range test to confirm. At a rate of 40Wh /mile it SHOULD get 65.8 miles in a worst case scenario (deducting 15% from 3108 for residual loss and remaining capacity at 0% / 3.3V per cell.
