Have you checked the 5 Amp "CHARGE" fuse on your battery? It's a bladed ATC type, under a rubber cover that can be pried out. They've been known to blow for no apparent reason and when they do, will produce similar symptoms to what you are experiencing. Rad instructions for checking/replacing battery fuses can be found here:

Hey there, I just wanted to send a gigantic thank you, this worked perfectly for me.
Story mode for Google hunters in the future:

A few days ago, while willing to lock my battery on my Radwagon 2019, I tried to insert my key into the charging plug of the battery (wrong side!), it immediately cracked with electric sparkles and I thought "OOPSIE I just broke my 5,400 km and counting marvelous bike". But the bike electrical assistance still worked so 🤷 I thought everything was fine (silly me).

Then today I discovered that as much as I wanted it, my bike would not charge. Immediately I went to the rad power bikes website (Good bye Europe, ARGH!) to try to buy a new battery only to discover:
1. it's 500 euros (!!)
2. it's not in stock

I tried a few Alibaba searches but quickly realized my bike may be dead...

Luckily, I found your post after searching for "Radwagon no more charging". Then I went to my local supermarket, found a 5 Amp fuse, replaced it and... TADA!!! It works. You saved me man, thanks so much.

Now what I am fearing is that my battery will completely die and then I would not know where to find another one, even a third party one,
