Dynamos are the new version of engines. All dynamos produce 80 RF/t at max output. As a reference 10 RF = 1 MJ. Steam Dynamos use some form of solid fuel such as charcoal along with water to produce its power. Magmatic Dynamos use lava or pyrotheum. Compression Dynamos use a liquid fuel and a liquid coolant. Reactant Dynamos use a liquid reactant such as mob essence, sludge, etc. and a solid reactant such as gunpowder, sugar, etc. Dynamos are also intelligent in that as power ceases to be needed and their internal power buffer fills they will slowly power down to a minimum of 4 RF/t or whenever they reach a power equilibrium.
You are correct that the energy cells work as RECs(Redstone Energy Cells) used to work in TE2. Additionally conduits have a limit per connection that is displayed on each tier of conduit. That means a limitless amount of RF may flow through any of the conduits but only the specified amount of RF may go into or out of the conduit grid.
In the future I would suggest you be a bit less rude and expectant from the get go though I will apologize for the rudeness of others who posted. It is unacceptable to meet rudeness with rudeness.
