mokwichi Posted December 5, 2015 Share Posted December 5, 2015 Hi Guys, I just finished upgrading my TG F5 which I love so much with a 500W motor and Controller (w/ bluetooth app) upgrade that I bought from Alibaba (see links). And the best part was that it was 95% swappable. The only thing that did not plug in to the new board from the TG board was the 5V led that's on the power switch, which I simply left unplugged. Everything about this mod was easier than I thought. The order from alibaba could not have been smoother. The Fashion MicorWorks company is on point. The shipped my item within 1 business day and the contact person emailed back within an hour of recieving my emails. I was expecting more trouble, but it all went smoothly. I am working on a video of how to do the mod which I'll post. But in short, my TG-F5 now goes upto about 17mph and I have the gotway app from which I can see info about the system. And I still can play my music and have my leds, so all is good. Stay tuned for video and pics of the mod if you are interested. Link to comment Share on other sites More sharing options...
Nevin@Tec-toyz.com Posted December 6, 2015 Share Posted December 6, 2015 @mokwichi hahaha, you couldn't wait huh. Just don't push it past the 30km/hr. Now you can keep up with us Link to comment Share on other sites More sharing options...
SlowMo Posted December 6, 2015 Share Posted December 6, 2015 USD 260 just for the replacement motor and board. It would have been more cost effective to buy a better unit as a whole. Link to comment Share on other sites More sharing options...
Compuatic Posted December 6, 2015 Share Posted December 6, 2015 Well done mokwichi Link to comment Share on other sites More sharing options...
esaj Posted December 6, 2015 Share Posted December 6, 2015 If it weren't for the high shipping costs (and possible customs payments), I'd get those (well, at least the motor) just for learning purposes (building a motor driver / custom mainboard)...

mokwichi Posted December 6, 2015 Author Share Posted December 6, 2015 Yes. The shipping costs are somewhat high. But like esaj said it was a learning experience for a tinkerer like me. Also, I couldn't find a uni that didn't have issues and that had Bluetooth music, an app and LEDs. The gotway mcm4 which I was looking at had some concerning reviews. The ninebot did not have a large enough battery. Neither did the IPS zero. So I was left to build my own. And after $250 mod, the whole uni cost me $740. It goes about 17mph and has LEDs, a large 528wh pack and Bluetooth music. So I got all I wanted this way for equal or less than market cost...

Nevin@Tec-toyz.com Posted December 7, 2015 Share Posted December 7, 2015 When you think about, it's a pretty good upgrade compared to buying a new wheel. Most brand name wheels 500Wh+, usually start above $800 anyways. Link to comment Share on other sites More sharing options...
Tomek Posted December 7, 2015 Share Posted December 7, 2015 Is the Gotway app fully compatible with this board? Link to comment Share on other sites More sharing options...
mokwichi Posted December 7, 2015 Author Share Posted December 7, 2015 Yes. I have had no issues connecting the Gotway app to this board and its (the app) that the manufacturer sent met! It's great. Link to comment Share on other sites More sharing options...
Colestien Posted December 8, 2015 Share Posted December 8, 2015 @mokwichi I think what you have done is great! I've been thinking about doing something like that myself. Thanks for sharing it, When I read about someone doing it, I think I might be able to do it as well. Link to comment Share on other sites More sharing options...
mokwichi Posted December 8, 2015 Author Share Posted December 8, 2015 good to hear Colestien. Its definitely doable. The hardest part was taking apart the bolts on the wheel. They will be secured on there tight. Really tight. So get a vice, a heat gun and some patience. Can't wait to hear how your mod goes... -mokwichi Link to comment Share on other sites More sharing options...

BecauseFun Posted December 8, 2015 Share Posted December 8, 2015 This is some inspiring work here. As a ninebot owner, I'd love to be among the first to try an 800 watt motor upgrade to a ninebot E+. Granted I have no idea if it would just be a straight swap from 500w to 800w (or 1000w… bwahaha!), or which motors to even look at, but from what I've seen, the E+ controller is used for the P which has the 800 watt motor. Until a P+ board is inevitably released, I think the cooling issues for the existing board using an upgraded motor could be addressed with either a small fan, an upgraded heat sink or both.

electric_vehicle_lover Posted December 10, 2015 Share Posted December 10, 2015 @mokwichi Thank you for sharing!! <3 I just created a wiki page sharing this information, I hope you don't mind: https://github.com/generic-electric-unicycle/documentation/wiki/Generic-Electric-Unicycle-upgrade-modding Link to comment Share on other sites More sharing options...
zlymex Posted December 10, 2015 Share Posted December 10, 2015 This is awesome. The board looks like the so called second generation(characterized by two large electrolytic capacitors but no current sensor IC) and one of my friends(I gave my IPS A130 to his son) assembled several EUs using the same board which performs very similar to Gotway MCM2. The cost is significantly less though at about 300 USD each with 340Wh Samsung batteries. Link to comment Share on other sites More sharing options...

That's the point of sharing mods. I'll try to get pics and any video up this weekend. Link to comment Share on other sites More sharing options...

Although I have a photo of the battery pack but I don't know the inside construction. I did tried idling very hard on the pink EUC and no BMS shutdown happened.

mokwichi Posted December 19, 2015 Author Share Posted December 19, 2015 Not on mine. I haven't been able to go fast or ona slope steep enough to get a shutdown... Link to comment Share on other sites More sharing options...
mokwichi Posted December 19, 2015 Author Share Posted December 19, 2015 Also though, shutdowns usually occur because of the bms not the motor controller... And there are ways to prevent shutdowns that you can see on other parts if this forum but you sacrifice something too. Usually over discharge protection. But some EUs have well designed or 'safe BMSs' and don't need any mods. Link to comment Share on other sites More sharing options...
