Been reading a lot more on this issue, my next concern would be if our cranking battery can run two units at once if needed and never worry about running the cranking battery too low. Ive seen here and other places recommend adding another battery but I dont really want to do that. Has anyone just upgraded to a group size 31 cranking battery? Ive seen that suggested with good results as well.

For reference I think a majority of the time if we switched to a size 31 crank the front sonar would be on while also running a couple of go pros? The only time we'd run both finders is if we were spooning? We are generally pretty cognoscente about not just leaving stuff on and or turning the engine on if stuff has been charging or running a while.

i haven't used it on my fishing boat, but there is a product I put on my ski boat in the early late 90's early 2000's that monitored the voltage and turned off my radio if it got to low to crank. it saved me more than once on a raft up listening to music and enjoying adult beverages and not paying attention. I think it was under the priority start name.

Could the 3-dc have two leads to a 24 v trolling battery system and the 3rd lead to the “house” or finder battery, or is the 3-dc designed for the big 36 volt trolling systems with all three going to those batteries?

. The DC3 has leads for 3 individual 12v batteries. I don’t see why you couldn’t use 2 lead sets to the 24v system and the 3rd set to the dedicated electronics. There is also a 4th set of leads that go to the start battery. When the start battery is charged it then charges the others. Sq

sounds like what i need (want). Starter charged up and keeping up the trollers and the electronics working. the last couple of days i have been researching the boat forums on the internet re this subject and have read about folks say, “go with the dc3” , or wished they had gotten the 3 instead of the dc-2. Thanks, sq
