I've been searching for all the connections you identified in this video. Perfect solution.....thanks for the effort and on-point video...

[@honeybadgervoodoooutdoors7305]

Glad I could help. You might want to check out this video as well: kzbin.info/www/bejne/p6O5hpihbKZrbrs

@@honeybadgervoodoooutdoors7305 Yes I had that lithium battery already on my Amazon list and I already own an battery monitor I can mount on top of the case you showed in this video. With the connectors you identified that may be the way to go. Also think I can mount the battery charger in the case with a connector to plug it in. Thanks

This works great! Thank you so much! 🤘🏻🤘🏻

[@maytheforcetry]

Ha "somethings gonna get blowed up" is right, I had an optimum battery on my inflatable dinghy trolling motor that started smoking while i was out on the water! Now I also switched to lithium :)

[@honeybadgervoodoooutdoors7305]

That's scary. In theory, lithium is supposed to be a little more dangerous, but they've come a long ways in terms of safety. And they are *so* much lighter.

[@KalvinLo]

love your cool video, somehow i never feel safe going out there like you guys

[@honeybadgervoodoooutdoors7305]

To be honest, I never feel that safe either, lol. But most things in life that are fun involves a little bit of uncertainty :)

Thanks. Glad you found it useful.

[@gregg7924]

Love the video. Thanks. One question I was looking to get some input on. Why do you have the wiring in the middle of your set-up. Ie. why don’t you use the wires that come out of the lithium battery (oliyin EC5) and splice them directly into the black waterproof wires (LED JUMP) coming out or into your box? Ie. I don’t understand why the middle wires (the Hopkins 2 pole) are needed? Sorry if the answer is obvious or I missed it in the video. Last I am assuming the female LED JUMP wire that connects to the male LED Jump wire (that comes out of your box) is then spliced directly to the wiring harness that comes with the Garmin Striker unit? Thanks for any of your help. And thanks again for the video. Much appreciated.

[@honeybadgervoodoooutdoors7305]

Hi, I need the quick connect/disconnect because I have multiple sources of power. I sometimes spend 10+ hours on the water, so I need something that I can swap out quickly. And yes, the LED is soldered directly to Garmin. Use heat-shrink and/or lots of electrical tape. If any part of the wiring becomes corroded (common), you'll face the most annoying gremlins.

[@gregg7924]

Thank you again.

[@honeybadgervoodoooutdoors7305]

@@gregg7924 Don's mention it, braddah. Go out there can catch some fish!

[@thepctech]

I think that your starter battery also has a round barrel connector that can output 12v at 10 amp. This is designed for a cigarette lighter adapter. I think that output might be a better choice for your fish finder and may give even longer run times. Have you tried connecting the fish finder to that output jack. Most of those starter batteries use the port you did because they can handle 600+ CCA (Cold Cranking Amps) needed to start a car. Your fish finder may use 2/3 amps. The 12v output on your starter is a much better choice to run the fish finder.

[@honeybadgervoodoooutdoors7305]

Thanks for the tip. I'll check it out when i get a chance.

Since the battery pack feeds 12v , is an in line fuse neseseary?

[@vm8854]

I have a Lowrance Hook 4. I purchased DBPower DJS80 12800mAH/47.36Wh/1000A. Before I did all the wiring, I tried to test just clamping the aligator clips direct to my FF wires. The FF powers up to main screen then shuts off. I do not know if the "intelligent" current protection is stopping it from working. I tried with and without powering the unit on. Do you need to turn the DBPower battery on? I ordered some EC5 connector cables, I am hoping by going direct will solve my issue. Appreciate any advice.

[@honeybadgervoodoooutdoors7305]

Hi, did the EC5 cable work? That's what I had to do with mine.

[@KristianSloth]

Hi Victor. I had the same problem as you. Check which plug in the car jumper EC-5 socket is hot and which is neutral. It was reversed compared to the OliYin connector cables on my jump starter...

[@shin90505]

Does Jackley or any other solar pawer generator work with fishfinder? so when I go camping with Kayak I dont have to worry about fishfinder battery.

[@honeybadgervoodoooutdoors7305]

If it outputs 12V, then it should work, although that's an expensive part that will get ruined if salt water finds it. I'd recommend something like this: amzn.to/2S6opWa

Great video as always! Do you need to push the power button or just turn on the power switch. I bought another jump starter that claimed 99900mah lol. Powered my lowrance hds7 for about an hour and a half. I have this specific one on the way now. I'm hoping to get 5 hours out of it.

[@honeybadgervoodoooutdoors7305]

Thanks. Are you buying this *specifically* to use it as a ff battery? If so, I think there is a better solution: TalentCell 12V Lithium ion Battery PB120B1 amzn.to/32CBoBF

[@KristianSloth]

I got inspired by your project and bought an Audew 1500 A, 20000 mAh car jump starter to power my fish finder but also to run my 12 v Bravo BTP 12 air pump when pumping my inflatable Zodiac. I don't have my fish finder at the moment so I have only tried the battery with the air pump. I can get it to run if I connect the battery by using the "intelligent jumper clamps" and press a boost button on the side of the black box but if I run a direct connection from the battery EC-5 socket to the air pump I get no current. Do you know what the problem is? You setup seems to be working fine without going through the "black box".

[@honeybadgervoodoooutdoors7305]

Gosh, not familiar with that model, so it's hard to say. Do you have a multimeter?

[@KristianSloth]

@@honeybadgervoodoooutdoors7305 I just did a test running the air pump from the cigarette lighter in my car and then from the car jumper through the intelligent jumper clamps and with boost button pressed. It sounds like the air pump is running at 1.5x speed from the car jumper and that worries me a bit. I don't know if the cigarette lighter from the car delivers too little current or the car jumper too much (if that is even possible?). I don't have a multimeter but I can get a friend to do some measurments. There is no "boost" button on the black box connected to the clamps on your DBPower battery? I'm not sure what happens when I press the boost button on mine but I hear a "click" and then I can turn on the air pump.

[@honeybadgervoodoooutdoors7305]

@@KristianSloth Yes, I'd rec getting a multimeter. Even the cheap ones on Amazon are pretty good.

[@KristianSloth]

​@@honeybadgervoodoooutdoors7305 I tested the socket with and without the black box and it delivers 14.9 V in both situations. That why the air pump was running so hard. Maybe a bit much for a 12 V appliance. My Garmin Striker Plus 4 cv will run on 10 to 20 Volt so it should be fine for that at least.

how'd that meat hook gaff end up working? Been pondering the same thing myself...

[@honeybadgervoodoooutdoors7305]

hi, for the couple of times i used it, i thought it worked pretty well. for a kayak application, i think the meathook just makes more sense. the longer gaffs are just too unwieldly, imo. i don't think it takes any more effort to bring a fish next to the yak, as opposed to trying to gaff it from 3' away. having said that, i don't keep many fish, and any fish requiring a gaff is one that i'd most likely turn loose. on rare occasions, i'll keep eater-sized fish, but that's about it.

Hi, I've since moved on to the honey badger double barrel battery compartment populated with twelve18650 batteries but I don't see any reason not to use the jump starter if you have a smaller fish finder. You might also want to take a good long look at the link for the talent cell battery blow. It is essentially a housing for the same dozen 18650 batteries.
