Okay, got the DD motor hooked up on the bike.
Installation was stupidly easy. I plugged in the stock hall + phase connectors directly into the 9FET that. No problems!
I am glad i chose the MAC motor over a DD. This motor takes almost the same watts in ( 33 amps instead of 36 ) and does just a bit less work. It is also quite loud to the outside world. People seem to notice it, whereas they don't seem to notice the MAC motor, which puzzles me. Something about how it radiates sound outward i guess. My lady said she could hear me outside. This is contrary to everything i've been told about DDs.
Only tested it at 36v so far. Top speed was 26mph while pedaling. Steady speed is about 23mph or so.
The one positive thing i have to say is that the throttle action is SUPER buttery. I can dial it down to hearing the individual phases firing off. There is no lurch and jolt of acceleration, and low throttle uses low amps, which in turn gives a very linear and responsive feel. I like this a lot.
Another positive thing is that the pedal drag isn't all too bad, then again i do not have regen enabled. The MAC definitely feels like pedaling a regular bike.. this feels like you have a very slightly rubbing brake.
Well, the meanwell's fan apparently doesn't work. It got super freakin' hot inside and started making a buzzing sound. I put a PC fan on top of it and it started shooting out mega hot air. wtf?
Shortly thereafter, voltage jumped from 41v to 48v and amps were all over the place from 4a to 5a. Opened it up and it was a bit smelly inside. Fantastic
Edit: the 48v meanwell has recovered, thank you cosmic jellybean. After cooling off some, it started back up at 41.5v and the current is now at a steady 6.67A as it should be.
Another edit: Oh dear, now that i started it up, it's charging at 6.66 amps instead of 6.67.
