DO I REALLY NEED A BATTERY TO RUN MY FISHFINDER?

DO I REALLY NEED A BATTERY TO RUN MY FISHFINDER?
I need to replace the independent battery that runs my fish finder. This video shows how I did that so you can also do it yourself. I run a separate battery to operate my fishfinder so that the battery on my Twin Troller will not be run down by my fishfinder.
My battery is getting old and does not hold a full charge any more than a few hours so I am replacing that battery with one of larger capacity that is almost the same size and weight and cost me almost the same price as my original lithium-battery.

I now use a different battery for a larger fish finder I now have on this boat. You can see that here: kzbin.info/www/bejne/norKaYmIgKmmbsU Thanks for watching, Gerry

[@clydeyoung63]

You have confirmed for me what I suspected...that I do not need a deep cycle lawn mower size battery weighing around 10 lb or so to power my kayak fish finder..a Garmin striker 4..I'm getting older as well but not too old to learn..thanks for teaching an old dog a new trick ..definitely subscribing..

[@LunkerFishing]

Clyde, we all need something new to learn! Gerry

[@Domino705-]

thats a pretty slick set up, i like how portable it is, reliable. thanks.

[@LunkerFishing]

Domino, it works well. Thanks! Gerry

[@pamelaklemp5615]

That is a really slick battery setup. I wonder if I could use that same battery for running bow and sterm LED lights. I have a PELICAN MONACO DLX PEDAL BOAT for fishing from. I don't keep her out on the lake at night but having a setup like that attached to running lights would be a wise addition. Say maybe for an approaching storm or for anytime dusk or darkness arrives before I get back to the boat dock or shoreline. Thanks for showcasing your system and I'll research getting something similar for myself. Nice video!

[@LunkerFishing]

Pamela, I see no reason to stop you from using this kind of battery especially for LED lights since they use little juice. The battery I originally had would run my fish finder for two all day fishing trips and this battery is considerably larger. Gerry

[@Hoggy1963]

Cool

[@LunkerFishing]

Thanks Don. Gerry

[@kagnewmp12]

As usual Gerry you have an awesome engineering mind or your just an expert at rigging things up and making them work. I plan on a second GPS fish finder as well but as I'm buying two 31 series batteries cause I fish from dusk till way past dark I should have enough power for everything. I am down to just 38 days Gerry till I make that call to Freedom Electric and it still seems so far away but I still have a foot of snow to get rid of.

[@LunkerFishing]

I have a T-Shirt from my 6-mos old granddaughter that says "If Grandpa Can't Fix It No-One Can!". T-minus 38 days and counting. Global warming can take care of the snow. Gerry

[@ginnyrueter3336]

Jerry, Is there a way to use a lithium battery like from a drill to run a simple depth finder like a Lowrance 4.

[@LunkerFishing]

Yes, I believe so. Somewhere , Amazon, eBay, etc. I saw an adapter that slides on to some batteries for drills and gives you wires to connect to a fish finder or something else. Do not forget to install a fuse between the battery and the item you are powering. Gerry

[@randallvanzalinge4544]

I love all your videos, I would love how to set waypoints ext. with the fish finder that comes with the boat, your tutorials are great, please consider doing a video for us first time boat owners

[@LunkerFishing]

Randall, the fishfinder that comes with the TT does not have GPS capability. Gerry

[@ronzzzo1]

Nice explanation Gerry. I have a Hummingbird fishfinder and I bought a Scotty transducer mount that I’m putting on the transom. The Scotty mount allows the transducer to be raised and lowered as well as extended to the appropriate depth.

[@LunkerFishing]

Let us know how it goes. Gerry

[@ronzzzo1]

Will do. I’ll send photos.

[@LunkerFishing]

👍🏻

[@jerryculver4370]

Jerry where did you get your connector that connects from the fuse to the battery and what size fuse did you use thank you

[@LunkerFishing]

Jerry, I am not sure where I got the connector from the battery to the fuse. I think I either got it at a auto parts store (like Pep Boys, Autozone, NAPA, etc.) or I got it at a place like Radio Shack or similar electrical supplies. Possibly a hardware store may have all those items also. The fuse holder came from an auto parts store and takes regular blade type small automotive fuses. The manual for the fish finder dictates the size of the fuse required. Mine is 3-amp. Good question. Gerry

[@LovingIdaho]

I run fish finder and trolling motor off same battery .

[@LunkerFishing]

I choose to not use the battery that gets me home for things other than that. You certainly can do that in your boat, it is a decision I have chosen for me. Gerry

[@LovingIdaho]

@@LunkerFishing , I have a smaller spare that rides in the stern of the kayak for emergencies. Never have had to use it yet . But , if the fish keeps biting …

[@LunkerFishing]

@@LovingIdaho Why bother having it with you and not using it? I am not in a kayak. I use my separate battery to power my electronics so as to not run down my propulsion battery. Trying to swim home with the alligators and snakes is not what I want to do.

[@LunkerFishing]

Since this video was aired I replaced the fish finder on the side and that extra battery. I installed a 9" Garmin and also added LiveScope and have two 16ah lithium batteries. One for the Garmin, one for the LiveScope, in addition to a Battle Born 100ah lithium as the main propulsion battery.

[@clydeyoung63]

Can I use one of the small say 30 to 50000mAh rechargeable power banks (like the one I carry in my truck to jump start stranded motorists) for this same purpose..and just recharge it at the end of the day?..you have really got wheels turning in this old mechanical engineering mind of mine..Thanks I needed that!!..power pack?

[@LunkerFishing]

Clyde, Without knowing the demands of your fish finder I cannot really say. If your fish finder draws less than the power banks supply then yes you can use them. In this video I am using a smaller fish finder that I no longer use. The battery I show you was more than enough to power that fish finder for an entire day, plus part of another fishing day. I now have a 9" screen Garmin fish finder. I quickly found this battery was not large enough to power that fish finder for more than a couple of hours. In order to power that new fish finder I went to a 16ah Lithium battery (If you look at my more recent videos there is a link to that battery below the video in "Show More") and I find that is more than enough to power the larger unit all day plus some power left over. I guess to answer your question, it depends on the amps your battery holds versus the amp hours your fish finder uses then multiply that times the number of hours you will use the fish finder before recharging it again. I hope helps, Gerry

[@clydeyoung63]

[@thefwaynes]

If I were to hide the battery and then add a switch that is connected directly to one of its wires to be an on/off switch would it hurt the battery?

[@LunkerFishing]

It would be no different than disconnecting the battery from the fish finder at the coupling, so no it would not bother it. I would however, keep the battery in the on position so after fishing you should turn it off at the battery. You would likely be charging the battery at that time so you would notice the little red light was still on at the battery switch indicating the battery was still on. You should install a waterproof switch away from the battery in case you are in the weather to avoid corrosion of the contacts inside the switch. Good question! Gerry

[@martyk9643]

How do you connect the wires in the box and what type of connectors and waterproof cables did you use.

[@LunkerFishing]

Marty, in the video I show you how I connected all the wires. Some of the waterproof connectors I purchased on eBay but when I look I cannot find them. If you go there or Amazon and search for 12V automotive connectors. They are more waterproof than what I used. The fish finder you use may require different electrical components than what came with my unit so make sure you read your manual so you do not forget to install something. Gerry

Jahangir, I am not sure how long it will last. I fish all day using it and then put it on a charger when I get home. I suspect it would last two full days of fishing at least. Gerry
