Hey, I have a Power Cell hooked up to Solar Panels with FluxedRedstone Cables. The INPUT works just fine ( RF Gen -> Cable -> Cell ), but the Output doesnt work ( Power Cell -> Cable -> Farm ). PowerCells also do not work with the AE Energy-Acceptor.

That's not a bug with the powercells. They work fine with all other mods that use RF properly. I guess these mods implement things wrong in some way. You did configure the output right for the powercell?

Yep. I did configure the output right, because it worked when using it like hits Cable -> PowerCell -> Farm(ExU2), but it still did not work the same way on the AE Energy Acceptor or with the FluxedRedstone Cables.

Please report to those mods first. I'm not closing this yet because I want to be sure but I very strongly suspect the issue is on their side
