Dual Battery Setup 2021 195S

I think I'll wait and see if I can run an extension cord.

Ok let us know if that works out ok.

Another option I forgot to mention since you don't want to mess with the wiring, is you can ask if the dealer will put in a second battery and dual-battery switch for you - probably a few hundrew bucks but then any warranty issues they would have to cover.

(actually, that is one of the things I got my dealer to throw in--during more normal times, that is)

Have your dealer install one of these, and the second battery. This is basically the stock switch on two battery boats. The engine charges the start battery first so you won’t get caught out with a flat battery. That would be suckatude of emended proportions, then it starts charging the house battery. The dealer should also move all of the house load over to the new house battery. You really should have this system regardless.






You are going to need about 200 watts of solar or larger to properly charge the house battery. You have to have enough amperage to push at least 10 amps at 15vdc to properly charge the battery, and on occasion equalize the batter, or it is going to sulphate like 212s stated. And it has to be able to do it long enough to complete a charge.

And there are only a couple of ways to verify your batteries are properly charged. The easiest is with a volt meter and a hydrometer. The second, and really in addition to the first step is to have an ammeter on both batteries to verify how much charge is going to the batteries While you are underway. The most accurate is to use a shunt type of ammeter, and second, which is the easiest is with a Hall effect type of ammeter.

There are pretty cheap but accurate enough ammeters judging by a couple of the reviews.

Or, you can rig up the house battery (with the BEP switch) so that you can remove it easily and take it home with you and put on a charger at the house. The engine should easily keep the start battery charged up.

And if you can get 120VAC power, install a quality battery conditioner such as a MinnKota PC 220 which will charge both the start and house battery separately and concurrently.

I’ve Looked at putting a 300 watt panel on my T top that will support and charge my OEM house battery while I’m on the lake using my fish finder, live well, and stereo. But that project is ways out yet.

my 2 batteries were just installed. new one directly behind the stock one. I have 1 large perko switch. 1, 2 and off and each number is for each battery. they both do the same thing. run the boat and stereo etc. I was under the impression that if you had 2 batteries 1 would just be for the boat, and 1 just for the stereo if you are sitting still.
i have no idea. rekon it doesn't matter if they are hooked up properly? also had a dual bank noco genus installed. all i have to do is plug it in.

It depends how it's wired. Seperating the house from starting load can be done but requires more hardware, wiring and install time. You can always run engines on both batteries and switch to 1 or 2 only when engines off and using the stereo.

@traderfj....if you only want the second battery as security I like @212s suggestion. I have the GB40 in case I run my single battery down. I DID up-grade my single battery to a TPPL which is waaaay stronger that a conventional battery. That way I avoided all the add-ons, a second battery that could unbalance the boat weight wise and changing wiring on a boat under warranty.

My 2021 190 fsh sport came with 2 battery, for starter and the other for accessories. I can run it independently or parallel. I thought this came standard for 2021 boat?

Hi,

I just bought a 195S Yamaha boat and want a backup battery and use a solar panel to top off both batteries. I also would want a 2nd bilge with a float to work off the 2nd battery. Do you think this would work? I'm open to suggestions.View attachment 141262

No this will not work.

I would not suggest experimenting with wiring on a new boat.

Like others have said, there are lots of posts on here on how to properly hook up batteries,chargers, and and or shore power in many different ways over the years.It is fantastic reading.

The accessory Yamaha volunteers for adding and charging a second battery:

BEP Marine Dual Battery Kit | Yamaha Motor Corporation, U.S.A.

It comes standard on many Yamaha boats. It comes with clear instructions.

A water resistant solar panel and charge controller can trickle charge the boat’s battery (or batteries with aforementioned kit) through the 12v power outlet next to the radio. These 12v outlets usually have a 10A fuse on them.

I use both the Yamaha dual battery kit and a battery tender 10w solar panel placed across the windshield on top of the boat cover, tied to the center cleats of the SX192 in the slip, plugged into the 12v outlet

But it is not necessary.

In 5 years I had to switch to the second battery once, when the original group 24 Imterstate deep cycle battery physically cracked open after 6 years of use.

As stock, these boats are designed to be left in the water with a single battery left on to run the bilge pump occasionally for 2 weeks with no issues.

Solar panels and extra batteries / wiring mainly provide piece of mind but little else except for added complication.
