Depends on the FF. Look through the manual and it should tell you the current consumption of the battery. Multiply that by how many hours you plan to be out and you'll have your battery size. For example if your FF consumes 0.5A and you plan to be out for up to 12hours then you'll likely need at least a 6Ah 12V battery. I have a really low power one and run it off of a 2AH RC NiMH battery.
