They then released an updated firmware which allows discharge to ~99V 

Thats what I thought when I mentioned earlier in the thread about Martys experience.

Yes I use the latest FW

So then this doesn't make sense.

I’ve posted this on various Facebook groups but wanted to also post on here for those that are interested in an aftermarket 3d printed alternative to the terrible stock CPro headlights. I designed and printed the mount to be used with the following LED light but I’m sure similar lights would fit:

Super Bright Bike Light for Safe Night Riding, 3000 Lumen 5 LED Wide Beam Bicycle Light, USB Rechargeable Bicycle Headlight Set, Waterproof Bike Headlight for Adult Kid Mountain Road Commuter Cycling https://a.co/d/fDXvHya
 

I designed the mount to be attached to the wheel using four M3 x 20 mm hex socket head screws. I will upload the STL file to whomever would like it!

It limits the max file size for the images so click here for the full set of pictures:

Wanted to make sure that everyone had access to this that wants it. I uploaded the front bumper extensions that are made out of PLA and updated the Cults3d listing today.

What's the method / best method for cleaning the suspension parts? I got caught outside in an unexpected light rain situation a few weeks back and while the wheel and suspension operate, the suspension feels "gritty", like it's being resisted by friction. I'm not sure what to take apart or clean, though, and with what.

Proper mudguards EUC producers, please..

(This just from wet ground and with extensions for the stock mudguard..)

As I have a thermal camera on loan for a few weeks, the EBCP after riding:
The motherboard is heating up the area around.
The hottest bit seems to be the part that holds the shocks, probably from the bearings.
The inside of the tire pattern is warmer than the outside (due to airflow I suppose)..

edit: I did not see any hot spots on the battery cases like one could expect from some BMS activity. Nice for the batteries that the temperature is even, but I would have liked a confirmation of balancing happening after charge. As it is only the distribution board area heats up after charge, and still is 12h after charge.

Thanks, yes it's nice doubling as a bumper and it would indeed help keeping the front clean from spray. 

As I do not like the internal spraying from the tire (ending up on the battery cases and a bit everywhere) I was more thinking of the internal mud guard though. I might model one someday..

Both, but more importantly I want to save the top of the battery cases from water spray, which the internal mudguard does a fairly poor job at.. I really wish the manufacturers could make a proper enveloping internal mug guard that would save the battery cases and underside of the motherboard case from unnecessary water and mud spray.

edit: If I recall correctly you had a BMS alarm go off after riding in the rain, with a rain cover. I suppose water must have come into the batteries from the spray of the tire, since the top was covered from the rain trickling down.

batteries are well sealed, the weask spot of the wheel are the trolley screws  and the motor cable.

not me but some people got a BMS alarm after heavy rain (happened to other wheels too), this could happen when humidity/water reach the charge board, once you dry it, it stops

Water not having entered the batteries sound like speculation to me (just like I speculate it might have entered). I'd prefer you where right of course.

I'd love to take your word for it, but I've never seen a disassembly of the battery housings confirming there is a seal. If you have a source for that I'd be very glad.
The top area of the battery housing is not protected from the wheel well either, allowing for water to end up on top of the battery case (I have seen it happen).

edit: It was GitDatPC here that had the BMS alarm go after riding in the rain with a backpack cover on top of the EUC. Hence me wanting a proper, well covering internal mudguard, to avoid excessive spray in the wheel well. Whether the water had traveled to the distribution board or into the batteries, the point remains that I'd prefer limiting that spraying.
