Will it hurt a iPad battery if u charge it to early?
No because there is no way to charge it too early. Charge it when it is convenient for you or when it needs to be recharged.
No, you can safely charge the battery at any time and to any amount, does not have to be to 100% every time.
No. Charge it as often as you need. My rule of thumb is to charge it when you don't have enough power to get through the next day.
If anything hurts the battery it's running it down to nothing repeatedly
