Power management

[kprice52001]

Ok, I have an 06 Stratos 294 and I'm adding sonic hub and networking my three HDS units with structure scan I am also ordering led lighting for my live wells and storage compartments as well as the deck. What measurements can I take in order to ensure I don't kill by batt. Right now I have one cranking and two for my TM connected to a three bank inboard charger.

Look into a group 29 or 31 battery for your cranking battery.

go with the biggest you can fit but the LEDS hardly draw any power. the HDS dont draw as much as you think. not sure about the SS unit though. you will be fine with a 27 but go bigger if you can.
