i need to know if the batteries i plug in will try and charge the solar panel instead of the solar panel charging the battery. so basically will this blow up?

you still have the diode or the battery backwards.
The + of the solar panel should be connected to the anode of the diode, and the cathode (+) should be connected to the + of the battery.
In other words, the arrow of the diode should point from the + of the solar array to the + of the battery.
the negative of the panel is connected to the negative of the battery.
put the + and – symbols on the battery and on the panel, it will help.
edit: I get the cathode and anode reversed, sorry. I just look at the arrow, it should point in the direction of conventional current.
edit2: re latest sketch, you have the battery reversed, with – terminal connected to the diode, should be the + terminal. Put the “+” and “–” symbols on the battery, it will help. battery – should be connected to array –
