I have two lowrance touch 12 and one HDS 10( I think gen 3) and a SS2 box for structure scan. When i night fish I have problems with low power after I run my units and night lights. If I did not use my LSS2 how would that effect my structure scan quality and would it help my power loss? I have run gr 31 AGM Batteries in the past and have had pretty good luck. I just tried a gr 31 heavy duty sealed and the problem is still there. My two units at the console have a separate power wiring direct to them. The touch 12 up front and the SS2 run of the original factory connections. When I ran a heavier size wire to run the two units at the console it seemed to help a little but the problem is still there. I run the info on my units and my boat motor charger shows it is getting 14.4 volts to the units. The units drop back to low 13 volts when the motor or charger is off and when my battery charge gets below 12.2 volts my units start shutting down on their own. Sometimes when they shut down the Ethernet source on the sonar and Structure scan changes. Never on both on a unit running both on screen. My boat is a 2013 Ranger Z522 that came with two HDS 10's and a LSS1.
