Auger Battery for my Sonar

Post By: malty falcon      Posted: 11/30/2022 5:17:05 PM     Points: 9422    
After buying a fancy lithium battery for my ice-fishing sonar 2 years ago, I was left without sonar twice last season because of bad charger issues.

My Ice Auger is powered by a Milwaukee 1/2" drill, and a big 5 AH Lithium battery. There are adapters for their batteries to power other things, like USB for phones, jackets, etc. The Milwaukee brand version has a little plug in the side as well as USB port, for $30.

I found a cheap little cord to fit the 22 AWG DC outlet, and fashioned spade connectors for my sonar. Now have a great power supply, should the sonar battery die again.

Another reason I like the drill to auger setup is I can drill pilot holes for my shelter's stakes with a 5/16" drill bit, and get set up quickly.

Hope you get onto the ice soon. I've been bored out of my skull recovering from wrist surgery, and can't reel or even unhook a fish for another 3 weeks. Grrrrr.

I built a short harness for the battery on mine so I didnít have to mess with the spade connectors to the battery anymore. Used some leftover connectors from a battery tender. Their plugs had a nice cover so I didnít need to worry about water etc.

Thatís a pretty nice setup! Anyone who solders and hear shrinks is ok in my book!

Hey Matty,
Not sure if this applies to your sonar, But this spring I set-up my Garmin Live scope with milwakee batterys and it works awesome, but was then planning on doing the same with my bow mount Lowrance HDS9 to keep less items tied into my main battery bank. I was ready to install and was told by Lowrance that 18v and 20v would burn out my screen. After further research i was told the same with Hummingbird. Basically only Garmin would operate on 18v + systems. Hope this doesn't apply to your unit, but wanted to make sure you were aware.

Chodeman, Good Heads Up!

I bought a cheaper converter for the Milwaukee battery that only had the direct output. Fortunately, I tested it and found 21Volt output!

That converter is sitting on the bench, useless to me. The Milwaukee Brand converter puts out a steady 12 Volts. Good warning to others- CHECK THE OUTPUT VOLTAGE BEFORE USING!

Good stuff malty! And chodeman great point to clarify. I am going to go look at these converters - great backup option, I have 3 Miilwaukee 18v batteries & can easily throw all them in the sled. Inevitably I run out of juice on my FF - (and my phone so have a battery bank or two) ... excited about this, didn't even cross my mind.

Great post! I will be ordering one of those milwaukee adapters.

Here is the battery adapter I am using with Milwalkee 4ah batteries, They also offer for Dewalt and Rigid.

I can run my Garmin Livescope for almost 4 hours per battery

and for powering your phone and other items, I use this.
