Mine has a shitty rubber lid that opens up on its own, but it is at least high enough on the frame that its away from the wheels and pedals.
I also have an internal connector that is exposed when I remove the battery, but that is a pain to access, the battery is very hard to remove.
Is the charging port of your ebike accessible during biking? With my e-bike, the connector is well protected while the battery is mounted.
