Can you run a stereo off the trolling batteries?

[Scott1298]

I have a light 1542 jon and fish small waters... and I've got a little marine stereo with no moving parts (radio/mp3/sd card) I'd like to add. Will my two non-cranking, deep-cycle batteries keep up for a day if I run the stereo (quietly), fish finder, and 55 lb thrust trolling motor off them? I can isolate the ff if necessary (because of electrical "noise").

Thanks

You could also get noise on your stereo because of the TM.
You didn't say how big your batteries?
I'm going to say it's probably okay but would be better if the TM had it's own battery and everything else on the other battery.

That stereo won't draw hardly any current at all compared to the trolling motor. You may get some noise though from the motor but some noise filters may fix it. You gotta try and find out.

Thanks guys, the way I have the wire run I could isolate the radio too, just the 27 would run the trolling motor and the 24 could run the stereo... but if I cut the wires there's no going back!
