Yet another problem with my er9. So, 2 RD died for no reason, that's being sorted.
But last night I put the er9 on my road bike to charge ahead of a mountain ride today. Battery was over 70pc when I put it to charge, I just wanted to make sure I wouldn't run out. In the morning, I start the ride, two bars as per be Garmin unit. And it wasn't a fluke. I did the whole ride trying not to shift and the battery died at the very end of the ride.
I plugged it in the wall. It was blinking green. It's not exactly the first time I handle the stuff.
So wtf happened this time? How is charging overnight actually draining the battery? Like wtf?
I am losing patience here. I really want that stuff to work, but man... This is really testing my patience, I feel like I should be getting paid to ride that stuff and debug it.

I had exactly the same thing a couple of hours ago. Previous derailleur died of water ingress. It seems like one bump on the road fried the 2nd one.

On a different topic, does anybody know which OSPW is compatible with this groupset? Not too long ago, I placed LTWOO's OSPW on an indoor bike, and the difference in sound is dramatic. Can we use the same one, and if so, which version specifically?

The repeated issues with this groupset are almost pushing me towards disregarding the groupset entirely and move to shimano. As a final and desperate move, I will try it with higher quality batteries. Thanks for the input all.

Not sure if this prognosis is exhaustive, but there is probably a problem with 1 of the 14500 batteries I had on my bike. Just compared two "new" 14500 batteries which were giving ±4 volts. The ones installed were giving ±3v (which apparently is the cutoff?) and ±3.5v.

Did anybody have to deal with a groupset that was only charging a couple of seconds after connecting it?

If so, was there a fix to deal with it? I have had numerous rides now where midride, the batteries are empty, even though I charged them the night before (or so I thought).

Clean build, thanks for posting! your saddle is tilted funny and your saddle bag is an eye sore though :p

I actually stopped to change my saddle angle, which on the pictures indeed looks weird. Sorry about the saddlebag; learned it the hard way to have some additional gear with me at all times.

I will definitely circle back the pictures, and can provide details on the build process. Especially on the topic of going mechanical this time.

Two pages fully corrupted. Is there a way to retrospectively clean pages from these corrupted files?

And back to the 268 frame topic: what would be the ideal approach to mount a narrower bar on this frame? Would it be advisable to use the headset provided by VB or take a different route entirely?

 

I'm planning to build my e-gravel with this group.
Would you mind to explain the known issue(s) of the group, as there are already 30+ pages.
The "dielectric grease" intrigued me 

The number one issue (and admittedly my only one) is water ingress. On my first set, after the first ride, I already started having issues. Note that I live in the enticingly moist Netherlands. After ride nr 5, I decided to add duct tape to the connections, which temporarily seemed to resolve all issues, until the 31st of Dec, when the rear derailleur died on me mid-ride.

The duct tape is not a full fix, and I personally only have one ride with the dielectric grease setup, but the latter solution seems to work for many people having this set.
