As a proud owner of a Unity and Enertion Direct drive mounted with a 12s5p battery pack from Eskating.eu and Nano-x remote, I would like to know if one of you guys had the same issue as me:
While going full throttle from a complete stop, the power cuts out, becoming really dangerous as it does not happen at the beginning, but 3/4 seconds after, once the board is already around 20/25mph. My friend had a crash on it last Saturday
The board has close to no power while going uphill, and if I press the throttle down, the power cuts out, same as the issue described before
Here you have my UNITY set up:
Does anybody has a fix on that ?
Which part would most likely create this issue ?
But i have the same issue with the new firmware., on 12s5p as well… it’s really make me worried… i crash once and i wont try my board again until they fix it
Try to re-calibrate your remote and make sure it’s in R-spec mode when you do, then run motor detection again. I’ve had a similar issue in the past after calibrating on slow mode only.
This may be related to incorrect motor detection issue. I’m not sure if there’s a firmware update that’s been released but there is a fix that I’ve been testing that does fix this. @Deodand would know better.
I will try later on the new firmware, but I am afraid to retry the test (full acceleration on the remote) as I broke my wrist already on it… Any suggestion to do the test in a “safe” way ?
Your Beta is too low, but that is not related to your issue. 23.42 is the latest official firmware, so usually your Beta should have the correct value. Where did you downloaded your firmware? If not from Enertions website, try to reflash it with the official release.
I still think that is not the cause of the issue. I have cogging trying to accelerate uphill from really low speed despite my sensors where detected correctly and I get a kind of cogging when I get close to topspeed, but it doesn’t feel like a complete power loss, so I am not sure if it’s the same.
Thermal throttling is more noticeable at acceleration in loss of torque. How far do you have set your thermal cut off values set apart? 100°C start 140°C end?
Did you updated the firmware with your phone via Bluetooth?
Enertion does not recommend this. Seeing the old Beta value in the new firmware looks like the update didn’t got through correctly. The temp limits can be set in the Focbox tool not the UI.
Lately there are a few reports on the same issue you have, mostly with higher kv 6374 motors, but not so many with the R-Spec hubs. It’s said that there will be a firmware update anytime soon which should solve the issue. I feel you it’s scary to get on a board with a known issue. That’s the culprit of having the latest tech. Let’s hope that with the new firmware everything will perform as expected!
