Yes if temps are within limits

Alright, just want to make sure before killing my new motors 
I have seen somewhere that someone posted a youtube link on how to add polyurethane rail protection to decks… i stupidly didnt save the link. Can anyone help me out with that one? My google fu has been weak.

I have problem with long steep hills. It seems as board just loses torque and then it stops. Thought I had mosfet thermal throttling, but no, temp didn’t go over 66 degrees C. Or could it be that only one ESC, not connected to telemtry, hits thermal throttling? Looking at log, power and current just decreases, no cut off or anything suspicious.
My setup is dual ESCape - with heatsink facing out of enclosure, 1:4 gearing, 8 inch, 180kv 80100 motors and 13s battery. I don’t see where lack of torque/power could come from
Btw I am talking about really steep hill, like 25%+

Steep hill starts at around 480sec mark

My escapes got replaced with TB6 this week for the exact same reason. Hottest esc was only getting to the low 80s according to metr, no faults, but slowing to a crawl on steepish hills. Start at 30mph and end up at 5mph.

Did TB6 solve your problem?
Only one ride(yesterday) and metr died so didn’t head to the hills yet. Would like to wait for my replacement to get here but will probably head that way today. It’s like 110 heat index though.

Let me know how it goes! It’s just hard to believe that escapes are not capable of something like this
You’re geared for ~70km/h top speed, that’s really tall for lots of hill action IMO. Do you ever go that fast actually?
Can you post a metr log?

I’m sure they are. Assumed there’s an issue going on and will send to @JohnnyMeduse once confirm TB6 work as should.

I’m only geared for 65kph and I do get that speed every ride. My logs are mostly over in the ride thread but I’ll try to find one where it happened. Metr signed me out and won’t let me back since it won’t connect.
nop, never reached 70 km/h - but I have 13s battery which gives me great top speed even when battery is almost empty. I just like to have more room until full throttle. Also take into account 80100 motos which should be powerfull enough even without 13s
Edit: I am logging with trampa app, I guess I could share csv file only?
same as with cisco…did you try fixing it with the metr guys?
Not that part but we didn’t work on e module for a while. They think it’s bad. Have four more coming and will get those first before bothering them again.

Steep hill starts at around 480sec mark, after 20 or so seconds I am walking next to my board while pushing throttle

Sensorless
For the record mine are not sensored. I can stand to lay the back of my hand on the cans but don’t truly know the temp. Unpopular fact…Flipsky dual 6.6 had no problem with the same task.

VESCtool is a pain in the ass… The left slider for zooming into a range doesn’t do anything useful and just stays at zero >_<
HFI or not?
Not sure what happened here. At 66c mosfet definitely not VESC thermal throttling, unless your cutoff start is earlier than the 85c default.
Maybe sensorless struggles at low speed / high torque scenario and looses track of rotor position?
Motors heating up too much and detection values drifting too far could have something to do with that too…
