Bug Report for Sophisticated Backpacks

Description of the Bug:
The battery upgrade in Sophisticated Backpacks mod is not discharging power as expected. When connected to a power source via cables, the backpack charges normally. However, it fails to discharge power when attempting to use it as a mobile power source for devices. The backpack only discharges power in the battery upgrade page's output slot, which is not practical for mobile use.

Steps to Reproduce:

1. Open the backpack interface.
2. Ensure the battery upgrade is installed and charged.
3. Connect the backpack to a device requiring power.
4. Attempt to discharge power from the backpack.

Expected Behavior:
The backpack should be able to discharge power to connected devices

So I double checked it and yes it does not work with AE2.
Modern Industrialization cables can only extract from Modern Industrialization Energy storages according to their description.

It does work with TechReborn.
So I'll investigate what is going on

Also checked against the NeoForge version of Sophisticated Backpacks and AE2 is not working with that either.
