Fish Finder Question….?
…i have a portable Garmin fishfinder and what i want to know is ,is it possible to ditch the 8 rechargable batterys im using now and connect it to a 12v motorbike battery ? the recharagbles are 1.5v so that makes up to 12v but is simply cutting the wires and running with an in line fuse straight to a single battery gonna work???
