Lund Power Supply Setup

[seanc25]

Hey Everyone, looking for some help with making sure I have an adequate power supply for next season. Here's where I am now:

 

2017 Lund Rebel XS Sport

Humminbird Helix 9 Mega DI GPS

FishHawk X4

(1) Scotty 1116 DR

Minnkota Powerdrive 55lb TM

Mercury Analog Prerig w/Gauges

 

Looking to add:

2nd Scotty 1116 DR

Marine CB Radio

Kicker or Terrova AP (still trying to decide)

 

Right now I only have the 2 stock 12v batteries onboard (one under the rod locker and another at the stern) and need some help with what I might need to keep everything stable/reliable.

 

Do I need an onboard charging system?

(2) inline 12v batteries?

Something else?

 

Attached are a couple photos of the battery slots as they are today, with everything unbuttoned for winter.

 

Thanks guys,

 

Sean

Do you troll with the big motor? You have enough power on board already for everything.Those 55 pound 12 v motors will drain a battery quickly  just bass fishing from my experience.  dedicate a battery for just the tm. Then add a on board charger to charge the tm battery when you get home. I am assuming that you trailer the boat.

I run 3 batteries on my Lund. 2 for the 24v tm and the other for everything else. I have drained the starting battery before when I am on the trolling motor while bass fishing and the big motor isn't running.  I have never had that problem while trolling

Unfortunately we do use the main motor to troll. Right now I have everything on the main battery with the exception of the fish hawk, which is on the TM (front) battery.

We troll primarily, then drift/cast second. I've owned the boat for 3 years and have used the trolling motor twice. Just not a bass guy. I've really only kept the TM on the boat as an emergency power source.

If I add a second rigger and the other stuff I mentioned am I still good running off the main battery?

Yes. The big motor will keep that battery charged while trolling.

On board charging for convenience only. Another batt if you go 24v TM.

Separate breakers for the DR's to cranking battery

I like a main fuse or breaker between fuse block and battery. Convenient when working on the electrical.

That helps a ton thank you.
