I have an 01 220 Dauntless running a 200 Opti

The batteries are groaning a bit too much this year when starting, so time to replace. I think these are the orginal batteries. I am the second owner.

This boat has two batteries in the stern and two battery boxes in the console for a trolling motor.

I read about house vs starting batteries, but not sure I understand exactly what folks are talking about.

Do yall have one starting battery (#1) and then switch to a dual pupose battery (#2) when running for the VHF, FF, sonar,lights,livewell, etc? But can you mix batteries? Or just run a pair of dual use batteries? Running a pair of starters just doesnt seem the best way to go.

I am thinking of a pair of dual use batteries.

Do most of yall run on one battery half the day and the other battery the other half? Or one on the way in and the other on the way out?

thanks in advance for your thougthful answers.

I recommend the BEP 716 Battery Distribution Cluster and here is why. The BEP 716 is ideally suited for a single outboard installation.

Here is how it works:

The BEP 716 will ensure that the starting battery is recharged after each start. When your outboard is started the 716 VSR directs all the charge to the starting battery. When your starting battery reaches 13.7 volts the 716 VSR connects the starting and house batteries, allowing both batteries to charge together. When your outboard is turned off the battery voltage will begin to fall back to it's normal operating voltage, once it has dropped to 12.8 volts the batteries will seperate ensuring the starting and house batteries are isolated from one another. This ensures that your starting battery has sufficent power to start your outboard.

There is a third switch on the 716 that gives you the capability to align both your batteries in the emergency parallel configuration for starting purposes. This is in the event that neither battery has sufficent charge to start your outboard (think of it as the both position on a standard marine two battery switch).

Here is the actual schematic/overview of the BEP 716.

Nice electrical setup!

Is your Guest charger set up to recharge both batteries or just your starting battery?

Have you been happy with your Cabela's batteries/

The Guest 2620 is a dual battery charger that I have setup to charge both the start/house batteries simultaneously. The Cabelas Group 24 AGM batteries have been terrific. The only drawback are the small battery posts.

Thanks for the kind words. It's really a simple installation just take your time decide what kind of system you want to install, assemble all the pieces, and then execute your plan.

Here's a few more pictures ... might give you a better perspective of the install. 12095938/file.jpg 12095709/file.jpg 12492495/file.jpg 16205287/file.jpg

I second the nod for a BEP Marine distribution cluster. I have been using this system in My Outrage 22 for 2 seasons now, and it is flawless. Installation is not any harder than the typical 1-2-both switch, and use is even easier. Just put the start and house switch to the on position at the start of the day, and turn them off at the end. Here's an article with some more details:
