Re: Domino throttle

Domino throttle use variable pot resistors meaning that you wipe from 0 - 5V. Most throttles use hall sensors which wipe from 1 - 4V. Most controller are configured for hall sensors so won't respond between 0-1V and will cutoff over 4V for safety purposes. So you have 3 options: 1) Easiest: Buy new ...

Re: Cheapest, Dumbest BMS?

Just because the tubing is stronger does not make an unbraced truss as strong as a braced one. I'm guessing the top tube to seat tube joint will go first, because it's the corner of the unbraced square with thin walled tubing on both sides. Agreed. Not the optimal geometry, but strong enough for th...

Are you using the battery case as a stressed member? Because otherwise, those right angle frame joints are going to be none too happy.
I am but even then this is plenty strong - Did some calculation and this is stronger then the original frame.

INWO, Building a pack/case for my bike with the 30 x 11ah. I ordered a 30s BMS, but it does not have balance function. Have you found it necessary? How would you wire the 2.7V Cap balance modules? Could I setup 3 x 10s modules together? Also, do you think just folding and crimping the Al tabs togeth...

Re: Battery packaging 11ah and 53ah LTO

Hey INWO/Dave, Got the cells (that was quick) and currently building a case for 30s1P. 11" x 6" x 8.75" ... now I need to figure out how to mount on frame. Pretty impressed with the cells I received so far - all within 1 mV - except one. Can't wait to test'em out! https://lh3.googleusercontent.com/G...

Re: Hallomotor hubs on ebay, August 2015

I wonder if this motor is the same as the leaf 1500w. Hey SamRich can you open your motor and measure the thickness of the stator laminations? I hope they are 0.35mm like the leaf. I wish hallo motor would put up a dyno graph or at least give us an efficiency number. I also saw this motor from Gree...

Re: Hallomotor hubs on ebay, 2015

I purchased that hub motor from Hallomotor last January (2015) and have about 2500 miles of mostly commuting on it so far and it's my favorite motor yet (have or had a Cute 128R, 9C clone, BMC V3, Bafang BBS02 750). With a basic Chinese 45 A sinewave controller it will run just shy of 40 MPH on flat...

Re: Surly Troll Build with New 1500W Leaf Kit

It will be a fun ride! I built something similar (1500W leaf) as my daily commuter with a 13S/18 FET sine wave controller...perfectly silent and hits 40 mph no problem. Having a large chainring also means I can actually push the bike over 35 mph and get a bit of exercise. :) Over 1000 miles on the h...

That's it I'm pretty much sold on these motors for my Sikk gas electric build. Still going to mount the MXUS 3000w in it just cause I already got everything to do it, but now will start looking for the next bike for the MXUS. :lol: Might want to look at hallomotor.com: http://www.hallomotor.com/201...
