I know the esc has a 30 amp fuse on itif that is any help- im no electric guy- im just trying to get the boat running. The batterys run in my cars and last a long time but have very little power for a long time. It's hard to explain. It's like they will go fast for about a minute then wil ldrop to half or under power. Maybe it's a combination- and in that case the boat may become a shelf queen. What would an ESC run me?
