batteries
 

i have a battery problem. The battries drain overnite and i don't know what it could be. Any idea of what it might be?

a draw. need to be more specific.

So, diconnect the batteries and measure the current be drained. I must be a large drain or your batteries are already exhausted (since you gave no info about battery age).
Did you recharge them? What charger did you use?
More infos needed...
