Your views on Battery systems
My plan is to install 2 Group 31 batteryies. One inline to each main engine, with on/off switch, plus line to join, just in case. will have 15 Amp Pro mariner bettery charger dedicated just to charge the 2 house batteryies.* Mounted very close to starters for short cable runs. Poet eng. 80 Amp alternater to start batteries.* Then 2 6VDC gulf cart batts. wire together as the house power. I do not anchor out, either running or at dock, plus 15KW Norther lihts. I will put a Master-Volt 30 Amp battery charger to take care of 2 Golf cart batts. and with 30 amps should take care of normal DC loads at dock. Please shoot holes or give me your better ideas to make system the best. Thank you for your views.
