Hello!

Not entirely sure if this is the right sub for my question, but my Merdia eBig.nine 400 doesn't charge properly with the charger attached directly to the charging port. It works sometimes but most of the time it doesn't. It always charges though if I take out the battery and attach it directly to it.

Does that sound like a faulty charging port or does anyone know if I am missing something here? The instruction manual just listed "Plug it in", which is what I am doing.

The battery is a Shimano EN806 630 Wh with a Shimano EP6 motor.

I'd love any advice on what could be the issue, I do need the bike daily to commute to work so handing it to the vendor for a checkup isn't the most appealing right now.

Thank you so much in advance for any tips! 😊
