i am using one of these 9v batteries -
but if i had a 9v battery that did power it long enough would i be conneceting it right and if the 9v battery link i gave you didnt work which battery should i use?
i was thinking a rechargeable battery but none were high enough power and i cant really use AA or AAA becuase my 3d printer dosent have a huge print bed only about 4 inches or 125mm x 120 mm.
