Stupidly i upped my lipo pack to 36s and looks like i have killed my 18fet lyen
I belted this motor hard for 20ks and it hardly got warm.... Just need better brakes now.
The 4115's generally don't really tolerate running near the 150V design limit like the 4110's take 100V. 32S is about as high as I would take it.
You must not be beating on the motor enough, since mine was burning hot to the touch after 5 miles of 100Wh/Mi abuse.
Also, it's looking like my bike is more efficient now. It's surprising how much it has changed after a few miles of using it, but the bike rolls much smoother now that it has 50 miles or so on it. I'm getting similar or better efficiencies than what my 1000W GM did, no concerning sounds or issues from the hub or wheel.
I backed the controller down to 8.x kW now that I blew up my 12 FET at 12-13kW, and the bike feels slow. It's really odd how big of a deal the few extra kW is. Going from roughly 8.5kW to 12.5kW is a HUGE difference in rideability. You can snap the throttle WOT at any point now and its just a gentle acceleration, but back when it was at 12kW, it was a wheelie machine that needed to be carefully throttled. It used to feel like a real monster when the front end never stayed down, AND it was accelerating to top speed in something like 2-3 seconds.
I need to get a beefy controller and run it at 15kW. Should be about the limit of whats sane for the frame. It does really good burnouts as is, the motor is SUPER heavy, and it has more than enough power to spin at 40 MPH, so the tire smokes quite a bit instantly.
