I tried every combination of wire, storage, and interface with all of Flux Networks' blocks and couldn't get anything to work until I ran my ID network through an Enderio capacitor bank.

it's not an issue

So basically Flux networks is not intended to be compatible with other mods' batteries or pipes? Or just Integrated Dynamics in particular?

@Shadowex3 No specific implementation has been added for Integrated Dynamic's Energy System, Flux Networks won't be able to supply to block if it doesn't implement Forge Energy, EU or GregTech. So it isn't a bug, but it could be added a later time. Can someone clarify though that Flux Networks doesn't send energy to Integrated Dynamics.

As far as I know Integrated Dynamics uses forge energy. I use Thermal Dynamics generators and machines with Integrated Dynamics logic cables and interfaces and I don't think that would work if it wasn't RF compatible.
