24v is needed to boost range , might be cool to add just one 12v in s but not 2 because of weight. to add one only is that ok ?

Ignore "Prakdrive". The higher the back emf the lower the consumed current. Its a natural speed governor for dc motors. You say you want "increase range" by which I take it you mean increase the distance you can go on one charge. The best way is to replace your existing 12V battery with a 12V battery with a higher Amp/Hour (AH) rating. You can connect more 12V batteries in parallel with your existing battery but you have to be VERY careful about how well matched they are in performance. You may find one of batteries getting VERY hot, possibly even bursting or exploding due to a mismatch.

Your power is the product of the current (amperage) and Electro-motive force (voltage) and therefore a rise in the latter corresponds normally to a drop in the former. However a motor is a highly inductive load and can take as many amps as it needs to overcome inertia. Adding another battery will give your batteries a longer mAH rating, but the induction of the motor will create an unsustainable back emf, resulting in an overcurrent which will either blow the fuses or burn the conducting system.
So no, don't do it. And don't put in a bigger motor either.

Sponge B is nearly correct. Adding batteries in series increases the voltage potential, adding them in parallel increases the the available amperage. Leaving the voltage at the required amount for the motor will not, however, pull more current. If your motor is a 24V motor, to do it correctly would require 4 batteries, 2 sets in series connected in parallel. If your motor is 12V, you can connect 1,2,3, or 4 batteries all in parallel. As long as your output voltage matches the motor's rating, you will be fine.

If already you have 2 x 12v batteries in series, which gives you 24v, adding another 12v in series will give you 36v, thus burning the motor out. If you are intent on adding another, put it in parallel but watch out for the increase in Amps, this will also burn out you motor.

depends on the control system and weather the control systemn controls the speed or not it is seriously unadivsable to do so because the speed control circuitry will need serious amounts of electricle skills youd be best getting 4 smaller (wieght) 12v and have a switch to alternate between the two series

You'll probably burn the electronic controller if you do this. If there isn't one, and the motor is a simple DC powered one, it will run faster, but will overheat. Why do you want to do this? If you want extra power, you'll need a motor with higher power handling capability at the same voltage. Don't risk it or you risk seriously damaging your bike.

NOT ok...
it would raise the power to 36V
at least overstraining, and most likely frying your motor outright.
to boost the 'battery cluster's' capacity, you have to connect them parallelly(spelling?) .

You will fry the electronics and the motor.

If you put them in parallel NOT series they will give you more range.
