...is there a way to get some sort of red and green led so i can see the charge state? then i dont need to open the box to test voltage etc.
What do you expect the LED to tell you?
Any time the sun is not shining, then by definition, the battery has a charge deficit (its terminal voltage is less than the ideal float voltage of 6.83V). You don't need a LED to tell you that...
If the sun is shining, then either it has not been shining long enough to put back the charge consumed during the previous night, and the battery hasn't yet reached 6.83V, OR the sun has been shining long enough, and the battery has reached 6.83V.
I would have no LED if the battery is low, and light a LED if the battery has reached full charge. That way, you are not adding 10 to 20mA of load to the battery when the sun is not shining!
I modified the circuit I posted above to include a LED that indicates that the regulator has begun to shunt some of the panel current away from the battery, meaning that the battery has reached the "float" voltage (not necessarily that the battery has actually reached its full charge state). To determine that requires a hugely more complex circuit...
I sharpened the knee so that the LED turns on more abruptly. R5 now takes some of the heat, so must be rated for 5W. I plot the battery voltage V(bat), the LED current I(D1) to show when it turns on, the power in M1 and R5. Note that the power dissipation is now split roughly 50/50 between M1 and R5.
i did start looking at this, but i dont want 230v and the input voltage isnt high enough

All of the crap to the right of that schematic is nothing but a four step voltmeter, which crudely measures the battery voltage, but doesn't really tell you any more than the simple one-LED circuit above...
