I've never run the battery down so low that the stereo would cut out. I've run it at 3/4 volume 3-4 hours.
I have 2 other group 24 batteries for starting the engines.
How does your 29M battery charge? Do you have it connected your alternator or just rely on a onboard charging system? Im just starting to learn how this stuff goes, so sorry for the lame questions.

I have 2 Perko switches. #1 on each switch is for the starting battery on each engine. #2 on both switches goes to the deep cycle. That way I can charge the deep cycle off either engine. I never put both switches on #2 when running. If I switch both switches to ALL, as long as I have one good battery, I can start both engines. I do not have an on board charger. A few times when I have run the stereo hard for a long time I will charge the deep cycle with a 10 amp charger overnight.

Thanks Griff, your help is always appreciated.
