Does the current affect the battery drain speed
The motor speeds up, back-EMF increases and current decreases, until the back-EMF is only a bit lower than the battery voltage. At that point the current is quite low. While the motor is speeding up it gets hot because of the high current. If used as designed, the current will decrease before the motor gets hot enough to cause any problems. - Download [PDF]
