 Battery System For Regulator With Verados
I am currently repowering my boat with verados. We are looking at batteries for the boat and I need some advice on the setup I am currently thinking about. The boat currently has two starting batteries for each engine and one deep cycle house. Electronics on the boat include raymarine c120 gps/sounder/4kw radar, vhf and a stereo system which includes one four way amp and 2 pair of bose (I will be adding atleast one more pair of high end speakers and two 10 inch amped bazooka tubes for the lows), and an acr spotlight. With the current battery setup the radar and/or stereo would cut off if you flipped on the spotlight. I am assuming this was because the battery wasn't sufficient. I was thinking of putting 4 optima d31m's 1 for each motor two for the house or just two starting batteries and a big 8d deep cycle for the house. The boat has a protournament 3 bank charger on it now I would like to be able to use this. My question is if I go with two house batteries can I still use the 3 bank charger. I like the optima idea better because of their reputation but the 8d that I looked at had a 400 minute reserve capacity 90 minutes more than the two optimas. What would ya'll recommend I know some people are already using the 4 optimas, how do you like that setup? Any ideas on how to get this right would be appreciated. |
