I use a house battery in my boy 16ft Starcraft. I run my helix 9, helix 5, fishhawk x4d, marine radio, CD player and charge phones of a group 27 that's not hooked to the main battery. Never had a problem and never have went below 11.5volts with the group 29 I have now. I am getting new cannon digitrol 5's and was wondering if you guys thought I could hook them to the house battery or if I should run them of the main battery hooked to the main outboard group 27? My kicker is a 5hp 4stroke and doesn't add enough charge to make any difference. Thanks for any help in advance. Sent from my iPhone using Tapatalk
