Is that a 5.5mm port?
Last week i was try to remove the charging port n accidentally insert the allen key into the port n its spark with smoke. So i quickly remove disconnect the battery, motor and the charging port cable. Lucky my battery n motor still working, only the charging port + n - has weld together as on picture.

Does anyone has to his charger port and knows where to get dust covers?
I did not change the charger.Well, I kinda didn't want to switch chargers or ports really. Hoping just the cover is easier to find...or so I thought.

Yeah, I guess that's an option. Splicing on different connectors might be a last ditch effort.
If so, maybe upgrade to a double-hinged plastic dust cover.
try this, get our main charger PLUG and some blu tack, use the plug to make a inprint into the blu tack, your basily making a mold, that you then fill w hotglue, you should be able to make a hotglue cover, that will last for now...till you find a proper one...worth a try

I've got a big 3" roll of black vinyl tape that I've been using that usually lasts a couple of chargings. Quick and cheap.
Gonna see if I can adapt this. Sticks out a touch but I could buy extra when the hinge fails.

As a electroinc desinger I must point out, that a 3 pin plug, for charging, really should stay 3 pin plug, as the 3rd pin is always a safety pin, for cell voltage or temp sensor, it would be unwise to change any 3 pin plug to 2 pin plug..... I know your not doing that so your all ok, its more for other modders.I've got a big 3" roll of black vinyl tape that I've been using that usually lasts a couple of chargings. Quick and cheap.

If on the other side (battery) you have only 2 cables to charging (+ and -), i think that 2 pins or a jack with 2 contacts are enough, no ?
Correct Patdam
sure mate, all good, maybe my post was not needed....I don't know each bike plugs it comes w yet, but in general its best to keep the 3 pin there if your modding to another plug...that already has a 3 pin plug...

I appreciate the friendly reminder. My only attribute is that not knowing better, I'd stay with the stock plug interface out of fear of messing up my electronics. That and avoiding plugged-in toaster ovens while in the bathtub especially if the spurned ex girlfriend is offering to heat up breakfast strudels.
Luckily, less water ingress potential in the desert here...but definitely dust intrusion can plug it up.

The connector has nothing to do with it. It depends whether they are using that 3rd pin or not. As someone who has spent 20 yrs as an ee in aerospace and an ev oem, it would not be a 3 pin connector to support battery temp sensing. They would use a rtd with a differential input so it would require a 4 pin connector. In this case the charger is not handling low temp lockout, the bms most likely is.

Ugh oh! This thread topic is in danger of turning into an Eye-Triple E mini symposium.
For us laypeeps....Institute of Electrical and Electronics Engineers. (I'm from a fam of EEs, but not me obviously).

Still kids at heart.
48V batteries are provided by the frame builders. For those i have: dengfu, SZZS and generic (for the lightcarbon) they have only + and - for charging, may be bafang battery (43V) use 3 contacts ?
I have lce930 with different charging port.
For 2A bafang charger you can fitt standard round 5.5mm connector.
Yes, you can fitt 5,5mm connector. In order to use it there are two options.
1. Buy lab psu 60V 5A.
2. Modyfiy ori 2A bafang charger, you will need 4,7kR and 15kR resistor, both 0,6W. Next solder then in the charger an replace bafang cable wit standard cable with 5,5mm plug.

Get some gorilla tape to secure the broken one and contact Linda/jean and ask for two of the v3 motor covers.
