No....you wire in series for 24v. Parallel gives you 12v

Two 12v in parallel is still 12 volts. Two 12v in a series creates 24 volts. I only have two in parallel to give me more juice and added weight on the bow. If looking for lightweight small and convenient, I would look into those lithiums.

They already have an off/on button..No need for a Switch to rust give problem down the Road..

And a setting choice to turn the transducer on or off. That is what pulls current anyway, in my thoughts. As an aside, tech support said turn it off if you have the transducer out of the water for more than a short run as it can overheat, particularly in the Texas sun.

Hmm. I'm going to test that. I'll just have to bring my Fluke with me, and measure the current the GLS10 is pulling. I already know it draws 13 mA when idling, or "off" (head off) while boat is sitting in the garage (tested when I installed). I will measure it in the "on" condition, with sonar on and off, and also will fool around with gain, range, and depth to see what affects current draw. For me to actually do that on the boat means it will have to be a VERY slow fishing day, or maybe I do it at the dock on the way home. Don't expect an update real soon, but maybe I'll start a thread after for those interested.

Now that would be a thread worth reading. My analysis was only situational and reflective of my experience with no scientific data to substantiate it. Your method would go a long way to establish a base of understanding. Great idea!

WE NEED THAT DATA!!!!

I have run my livescope over 9 hours in a single day with this dedicated battery, and its compact enough to fit in mist storage hatches.
