lithium ion battery for livescope...is it worth it? I need a new battery on my boat. Is the ion battery worth the extra $400.

Ernest,

I bought a dedicated battery for my livescope that runs the black box and my 1042 screen. You certainly don’t need to spend 400 plus. I bought the 14.8v 19ah version and I have never come close to running out of juice.

I plan to get with David at shut Up And Fish and move my electronics to a 100ah Lithium before next year. Currently have 2 31M gel batteries in a front compartment to run both scopes even though I seldom turn the second one on. Several folks I know run 2 12s all day on one 100ah lithium.

Just got my 30 amp/hr in yesterday
I’m running it as a moveable unit so it’s all concealed in a tool box

Anyone tried using the DeWalt 20V volt batteries as shown on youtube?

I looked at the Dewalt 20v and worked through all the options to go down this path but finally opted for one battery in a concealed box being able to take the very light box with me. I used the box idea from Ice Hole Power on YouTube and built my own box. It was pretty simple.

With this setup I run both my Echomap 93sv AND the GLS10 livescope brain with one SAE connector on the side which also doubled as the charger port. The battery is a 14.8v NMC Amped outdoors with 19Ah inside the plastic ammo box. I have used this setup for 8 months now and could not be happier and always have plenty of power left. Now I usually only fish a max of 6-7 hours with the Livescope running the entire time and suspect this setup would last even longer. One other benefit is that when I am done and back home I also charge my iPilot Link Remote through the USB ports on top of the box when charging the battery.

Dakota lithium just announced an 11 year warranty on all batteries, even retroactive purchased

Is it 11 years free replacement or 5 years replacement. 3 years pro rated and 3 years a 15pxt off coupon? Look at the warranty more than the years with the lithium’s!

I tried the Milwaukee 18 v and it only would last 5 hours max, But they're 3 year old batteries. So I just took 2 for the day. I was surprised it was a simple $16 converter. I ended up running it to my main motor battery which is a Everstart group 31, no issues for 18 months. Back to your question, does a lithium make a difference? Not enough for another $400, I bought Litiums for the trolling motor.

The 100AH GYLL is working great! I experimented with it last weekend, I fished a total of 16 hours in 2 consecutive days. Upon putting the boat on the trailer Sunday, I looked at my Garmin screen and the voltage reading was 12.2V. The battery is running a Garmin 1222 and (2) Lowrance Carbon 12” units. So far,so good! The 16 hours of use was without a battery charge between trips.

I use 2 Milwaukee 18v 8ah tool batteries. One powers the black box, one a 1022. Fish 8 hrs no problem. At the end of 8 hrs, graph reads 19.1v.
The Garmin can run on 20 volts. The 18v lithium batteries read 20.1-20.4 when fully charged. I wouldn't want to put a 20v on the system as they might reach 22v fully charged. Might over power the system. Price on Amazon for 2 Milwaukee 18v lithium 8ah batteries with charger was $238.

The 14.8v 19ah lithium with charger from Amped Outdoors is $169.99. IMHO, no need for a $400 lithium battery for Livescope unless that is what you want. I like the lithium batteries for less weight, which allows you to mount them at the front of the boat without the weight. Closer to the Garmin, the less power loss thru wiring.

Look at Amped Outdoors website for the power usage data on Garmin units. Very informative.

lithiums are great but watch the voltage on the unit while your fishing, because when they crash, they crash fast. once they drop to around 12.3 volts volts, they drop to 9.00 or lower very fast and MrGarmin will close shop on you.
Im running an 18 volt Dakota lithium and have fished 7 hours intermittently , putting the unit to sleep between spots, and the lowest it dropped was 13 volts. I carry a small 360 cca lawnmower battery in a very small igloo cooler, just in case. im going to test it soon and see how long it will power the system, in case I would ever need it.
I also wired my battery charger directly to the battery, so I dont have to worry if the clamps that came with it are making contact or not.
next im going to add a volt meter on a switch that is mounted to my portable livescope box, so I can just push a button and see what the voltage is before I go out.
lots of different options out there, I thought abt buying the RIGID POWER TOOL BATTERIES. as they are advertised to have a lifetime warranty,. but after trying to decipher the warranty terms, I got a headache and gave up.

Looks pretty solid.
they say if defective in the first 5 years, they will replace it, if after 5 years to 11 years they will repair it, free of charge. as long as it was not abused, over charged, salt corrosion, ect.
If they actually stand behind the warranty, only time will tell, but I havent found a better value out there

I have an eighteen amp hour Dakota and a ten amp hour in an ammo box. i usually fish until I run down one battery and then switch to the other. I was thinking I read it is better to run down the batteries before recharging them.
Dakota has a ten percent discount for all veterans also.
