[Bugs] Battery not storing and Side Connector Bug

[moeux]

My battery doesn't seem to charge, despite having input.

Also the side connector does not work as intended. It only accepts input from the side which does not have the input texture.
See screenshots below.

I'm using Fabric and mechanicaltech-0.3.0+1.16.
