GARMIN LIVESCOPE Voltage Drop Test

[@iceholepower8012]

In this video I test the voltage drop of the Garmin Livescope using 18AWG and 10AWG wire at various voltages. I also discuss the power consumption of the black box while the unit is off. #lithiumbatteries #iceholepower The Amped Outdoors 48Ah NMC battery can be found here: ampedoutdoors.com/collections/lifepo4-battery/products/48ah-lithium-battery-14-8v-nmc-with-charger?aff=8 For the Boat box that was seen in the video: www.iceholepower.com/product-page/ihp-boat-box Follow me on Facebook! facebook.com/iceholepower All batteries that I recommend based on my reviews can be found below: www.iceholepower.com/lithium-batteries Tools and supplied that I use in this and other KZbin videos can be found here: www.iceholepower.com/tools-and-supplies Contact Information: For business inquires or other KZbinrs ONLY.

Jeremy, great work. Thank you for the time and effort to set up this demonstration and present the data. I spent 32 years trying to show young technicians this "Voltage Drop" principal. I stopped calling it "Voltage Drop" a long time ago as a don't like to use slang. I refer to it as a "Voltage Usage" test. Of course, we want the LOAD, in this case your fish finder, to use all the voltage and not the wires delivering the voltage. The 10 AWG wire is superior to 18 AWG wire and your data proves it. I would also like to thank you for mentioning more than once a technician cannot monitor "Voltage Usage" to a LOAD if the LOAD is not being asked to work. Thank you thank you thank you. I also asked the technicians to use the unit of measure millivolts (mV) any time the voltage results are less then 1 volt. For example, 0.056V is written and spoken 56mV. Take care and thank you.

Great content! So what you are saying is the larger the wire the lesser the voltage drop. However in this case these are from relatively short runs of wire and the voltage drop is negligible. Thanks Jeremy these short little lessons are very helpful

I really like what you've done in this video. I was hoping you'd test voltage sag difference, if any, between SLA/AGM and lithium (NMC and LFP?). Everyone talks about how much power those Garmin Livescope units pull, and I guess it's a lot compared to conventional sonar, but it's not like those are huge numbers. I bought a 2nd-life LFP battery module, out of retired medical equipment, that has about 18.5AH worth of capacity ($45). That's enough to run Livescope for about 10 hours. It connects to the wires on my unit with an XT30 connector and about 3' of wire run, so total overkill. I can spell "attenuation", but there's none on my boat!

As always, great content. I know I appreciate what you do for everyone. Thank you.

AWESOME job Jeremy, i love the info. I am VERY new to this and I am getting my first Livenscope this week and I want to put a battery in the rod locker of my boat to run it, but I have NO idea what I need. I am getting the Garmin 32lsv with 92sv unit. Can you please give me an idea of what I need?

Don't laugh too hard but using Helix 7 SI G4N with Mega Live from my float tube. Looking to make new battery box with two SAE ports, one switched to turn Mega Live off when not in use. Luckily I already have a couple of 23ah LiPo batteries. Hard part is finding the perfect sized case.
