Dedicated battery eliminates voltage drop from the trolling motor, and stator fluctuations as well as ignition noise from the motor. Both very good things to eliminate, but in reality the starting battery is usually good enough.
What kind of battery do I need for a fish finder?
Most fish finders use between 12 and 24 volts, and a 12 volt battery is plenty for most kayak fish finders. Ampere capacity is given in amp hours (AH).
How long will a battery run a fish finder?
with most fish finders using about 2amps, you could run it for 50 hours. most trolling motors use about 1amp per pound of thrust at full power. so if you had a 50 pound thrust motor running on high for two hours, your battery would be dead.
Can you run fish finder and trolling motor on same battery?
Agree with the posts just a above. The interference would come from a bleed over from wiring on circuits that run parallel to one another. Running them on the same battery should not pose an issue.
Can you wire a fish finder directly to battery?
Wire Fish Finders Direct To Battery
Wire the fish finder direct to the battery (either the cranking battery or an auxiliary battery). Don’t take shortcuts and run the fish finder power wire into a block or switch panel. … **Refer to your Humminbird Helix and Solix install manuals for the correct gauge wire and fuse.
Can you use a lawn mower battery for a fish finder?
You can use a small 12V sealed lead acid battery (“gel cell”) – an 8 amp-hour battery will run your depth finder for a good 18 to 24 hours continuously. A lawnmower-type battery is a pain, as you have to worry about spilling acid in your boat.
Are portable fish finders any good?
Portable fish finders are great for when you can’t permanently mount a unit on a boat. They are a superb solution for temporary mounting on small boats, taking on trips, and fishing from shore.
How long will a 12V battery last with fish finder?

What size fuse do I need for fish finder?
Pic – 10A Breaker or 3A inline fuse for Fish Finder.
What is the best battery to use for a trolling motor?
Most trolling motor batteries fail due to lack of proper charging. We suggest selecting a 12 volt deep cycle marine battery with at least a 110 amp hour rating, usually a group 27 size battery. The higher the amp hour rating, the more run time you will receive.
Can you use 2 fish finders at the same time?
Any time you run two units with the same frequency there is a risk of interference. However, with the modern noise rejection systems built into today’s fish finders, in most conditions when there is a unit on the front and back of the boat with the same frequencies, they will not interfere with each other.
Can you hook up depth finder to trolling motor battery?
You can run it to the starting battery with an inline fuse and it will work and that used to be the industry standard until recently. Running it to the trolling motor batteries is asking for issues.
