I am busy with setting up a basic inverter battery backup system. I want to use cells to  create my own battery bank. If I connect 2 same cells in parralel, each cell with 0.5C discarge rating. Does the rating now increase to 1C?

1C for one cell, yes.

But you could think of it the other way. Suppose you have two 50 Ah cells; for them by themselves, 0.5C is 25 A. But if you connect them in parallel, you have in effect a single 100 Ah cell-pair. So now they are capable of 50 A (with each working at 0.5C), which is 1C for a single cell, but it's still 0.5 C for the paralleled 100 Ah pair.
