The BEST Battery Size For Fish Finders | Livescope | Garmin | Humminbird | Lowrance

[@skipman4735]

I'm using DeWalt 9amp battery's with a buck boost regulater. I'm powering a 94 sv for ice fishing. Works great. I carry an extra battery and have never even had to use it. I own a lot of DeWalt batteries and wanted to utilize them. I can charge them in an hour with my solar inverter.

Thanks for this. Great explanation and exactly what I was looking for.

[@goodmanfishing]

Great to hear!

Some guys are running the 19v battery’s for the graph stuff. Usually with voltages, As voltage Increases amperage decreases. I would assume if you ran a system on a 12v and used a clamp meter to measure the draw, you would find that it’s a higher amp draw than when using the higher voltage. Yes as the voltage drops in the battery, the amps will increase. Measure it and see. Electricity works the same no matter the application

[@goodmanfishing]

Yes, Ohm's law certainly still applies here. Performance of the image does not seem to be improved, however the higher voltage will help mitigate voltage drop.

Dude awesome video and you made it so easy to understand this stuff I had no idea how it worked! Thank you!

[@MegaGlennP]

Just setting up my Livescope. Great explanation! Thanks

[@goodmanfishing]

Glad it helped!

Excellent video!!

I just installed a 93SV, and bought a Livescope to add on. I am going to make the live scope portable, mounting the black box in a crate or box, but most of the time I will just use it in my boat. The 93SV is powered by a 12v 10AH lithium battery (which is plenty for the 93SV). Should I also put a lithium battery in the portable crate for the Live Scope? Is hooking each to it’s own battery okay? Or do I need to buy a larger lithium battery to hook both units to? Your video was very informative.

[@LarsonFishing]

Underrated educational video here! 🤘🏼

[@goodmanfishing]

Appreciate it!

[@tubingtomtom]

Perfect information!! Thanks!!

[@ke3552]

Nice work, subbed. Thanks.

Great explanation.I was looking for information on using a deer feeder battery to run the striker 4. And 0.4 x 18 = 7.2 AH and I’m looking at a $20 battery that’s 7.5 Ah that should give me 18 run time.correct me if I’m wrong.

[@tommckelvey3609]

A $20 7.5Ah lead acid battery should not be discharged to 100% Depth Of Discharge on a routine basis, doing so will greatly reduce it's life span. To get a decent lifespan, a lead acid battery should not be discharged past 50% (12.1 Volts) on a routine basis, and it should be fully recharged as soon as possible after discharging it. You can run the Striker 4 for 9 hours without issue. IF you want to routinely get 18 hours out of it before recharging, get a 15Ah battery.

[@Harlanmote]

I would use anything other than a drill battery. Spend some money and get at least a 30ah battery. Drill battery’s don’t last very long. I’ve tried to go cheap and use them. But they just don’t last long not on a 106sv

[@BScyd]

I am wondering on the calculations. Lithium batteries, as I understand it, can be run to just about zero power. Lead acid can only run to 50% before battery damage. That would really change the length of time they would power the units. Am I thinking about this correctly?

[@goodmanfishing]

That's correct. It's factored into the spreadsheet based on what chemistry battery is being used. It's a big deal!

[@USL.Website]

Great Video Thank You! Just wanted to ask, is the math the same for DC volts and AC Voltages?

[@KevinR00753]

simple mind...sorry, need my math checked. 112 ulterra, 56 amps wide open, usually run around 7 or 40 amps. 36 volt 100 ah battery would be 25 hours of run time?

[@goodmanfishing]

Are you looking for run time at 40amps? That would be 2.5hr of run time on a 100Ah 36v battery. That's probably quite fast I would imagine, probably 2-2.5mph. So that's 6/7miles or so of straight trolling distance. I run a 36v 60Ah on my boat with a Force and only use about 20% on a long day of fishing.

[@qouavang3646]

Just get an amped 32 or 30 you'll be fine. Can go 2 days on a 32 with 70% brightness

[@goodmanfishing]

Amped makes a nice battery. I personally prefer LiFePO4 versus NMC chemistry batteries. I believe their 32 is NMC.

[@dennishodson990]

Power Draw (33W) /Battery Capacity (288 WH)= H ?? 288WH/33W=8.72H

[@ntj030885]

Is your eco worthy battery a good battery? I’m looking to buy and don’t know witch brand to go with.

[@goodmanfishing]

Been so far. Just don't charge it below freezing! I'm going to do a capacity test on it this week and see what it does

[@twhite1963]

With a 135 Mercury motor

[@twhite1963]

80 thrust trolling moror

[@cryptojohnny7781]

Ya I think you are over complicating it lol

[@goodmanfishing]

Perhaps. There are a lot of folks that just go by other people's random recommendations and get something way too small!

[@jdreichel4939]

You need a bigger charger. 🤣
