DD Mad Speed. 12s4p TB battery and enclosure | FSESC 6.6 dual | Mad Hubs DD conversion kit | TB 110 | TB 218mm trucks | sector 9 drop through deck, top mounted.
Simple recepie, lots of hard work, (courtesy of @pookybear) and some borrowed components also @pookybear The results are amazing! So far able to top out at 43MPH…the speed is insane this Direct Drive is nuts!
Although the drives I received need a little attention, and I believe a loose magnet may have blown two of my vescs, This comunity is really coming through with the support! Thanks to @pookybear who let me borrow his DD kit and also his FSESC 6.6 Dual, I am not only up and boarding, but also boarding on what is a very sweet and smooth set up! I know the TB battery and enclosure is not ideal, due to its size and the discharge BMS, also my old sector 9 deck is not the best, but it works well, and handles beautifully! In the future I am hoping to migrate this build either to a HAYA or maybe a Hummie, but for now this will work.
A little about the drives themselves. As with other DD set ups and Hub motor builds, breaking at low speeds is not very good, but I’m talking about under 5 Mph. Also hill climbing, still playing with settings but so far it’s not as good as my previous belt drive set up…but I wasn’t really expecting it to be. Currently my settings are:
Battery 30A
Motor 60A/-60A
Sensorless
The torgue is great, and I have not tested the 60amp set up on a big hill yet, will test that later today and post my findings. Also I understand that with the gigantic TB wheels I am expecting to see less torgue.
This is all I got for you at the moment, feel free to ask question, this is my first build thread, also input is appreciated. Again big shout out to @pookybear for helping me make this happen! And of course @rey8801 for organizing the group buy!
On the app I only see the possibility to select forward/reverse I guess I need to use the PC. DOes the unity now support TCP connection or I need to open the enclosure?
Loooool! No that label is staying on! Mostly tho for testing to see him much heat it can handle loooool! I’m surprised it hasn’t melted off or set on fire yet!
BT connection on unity was sketchy when I had it. Not sure about now as well as if it supports TCP connection. I’d open the enclosure up. Post in unit support thread?
Ok rode home with this setting. It works 200%. Even too much. I would say half of the value you calculated are already good. I could fully brake because the first time I did I approced the cross by sliding the last meter . It also held me on slope. But you have to be more conscious about brakong because otherwise they try to go reverse that’s why better to lower it I think. I will try around 2000 next time.
I aspected as I’m the Ackmaniac firmare thst reverse is only engaged from fully stop wheels but actually no if you go full reverse or even close to that it will start trying to go reverse and lock your wheels.
