We have installed 2 cranking battery`s on several boats and just connect them parallel. If one battery doesn`t have enough storage to run the accessories, It still won`t on that setup.
First off....I'm glad you responded. I was hoping you'd chime in. I see you help folks a lot and you seem to really know your stuff.
I know that simply paralleling another battery would help. Just thinking that an isolated battery would benefit my situation twofold. One, I wouldn't have to buy an identical blue top battery (I have three group 31's that are good in my garage, but non match each other or the Optima ). Two, if I did drain them both, I would still be trolling my [censored] back to the ramp to jump off the batteries. Lol.
The blue top lasted about 4-1/4 hours of start and stop fishing. It is only 3 months old and very well maintained. If I added another just like it, paralleled, it would likely not make it long enough for a full 8-9 hours of fishing.
Do you think that a group 31 with 125 minutes of RC could be able to run 4 3a graphs, a LSS unit, and 4 pumps on timers for a full day of fishing?
The previous boat, an older Nitro, only had one pump for the single, divided livewell. The Skeeter has completely separate livewells with dedicated pumps for fill and recirculate.
Mondays tourney was unusual though, I had a limit of big fish within 45 minutes of launching the boat and had to use both wells all day.
Any other opinions?
