Easy DIY Adding a Second Battery to a Yamaha SX210 (AR210) Jet Boat 2017-2020 2 Battery Dual setup

[@christofersundlof7974]

This was actually the first helpful video I’ve seen on adding a second battery. Thanks man

[@lflsremodeling]

Awsome video. Simple and to the point. I'm elbows deep into installing a second battery on my sx195.

[@pastorfred3460]

I noticed the seat belt about halfway through the video and thought, "Genius!"

[@Channel-About-Nothing]

That was the seatbelt off the jazzy I got the gel cell battery out of. I love to repurpose.

[@gonzchi]

Thanks for the video. Very clear, just now what I need. I have the boat in a marina and I would prefer not to have to charge the second battery periodically myself. I need automatic charging with an ACR

[@ksp81]

I bought a 2018 SX 210 that already has two batteries. It seems like both second battery posts are wired to the first battery posts. Or otherwise, the + (and -) on the 2nd battery is directly wired to the 1st battery not the switch. How will this effect operation? Thanks!

is that split loom protecting your cables? what size? 1/2" 1/4" ?

[@Channel-About-Nothing]

3/4" here is the link to it www.amazon.com/gp/product/B07N483W7K/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1

[@Channel-About-Nothing]

it was 3/4" which I don't see anymore from where i bought it.

[@serenitynoobosity5905]

Does the negative bus bar need to be grounded or bonded to the metal on the boat (mine is fiberglass, so it will be hard to find a spot), or is the fact that it is connected to both negative batteries terminals enough to create an acceptable ground?

[@Channel-About-Nothing]

The short answer is no. The ground in this case comes from the engines which is where the ground connects and is ultimately grounded to the water.

[@kenthale2010]

Great video and simple explanation - doing the same to my AR190. One Q: what gauge wire did you add (the ones your friend made)? Thanks so much!

[@Channel-About-Nothing]

Everything is 4 gauge except the wire to the fuse block is which is 6.

[@kenthale2010]

@@Channel-About-Nothing Thank you - one more question - your gel cel battery is grounded with the main battery - what is the second ground/black wire from the gel cel battery connected to?

[@Channel-About-Nothing]

@@kenthale2010 I should also say I did a second video that started more from the beginning. kzbin.info/www/bejne/jaOaY2uMgLGAaJo

[@PBS-nm1uu]

would of like to see how you wired it. different from others.also if it is better than marine please say what kind of cables they are.??

[@Channel-About-Nothing]

I should have done a step by step instead of an after video, sorry about that. The wire came from a friend that maintains a cable company's data centers. It was leftover and going to be thrown away so he got it. It cost an insane amount per foot, like $10-20. Such an overkill I didn't think anyone would ever buy it. If you want excellent cables made in the USA at great prices go to batterycablesusa.com . Cables from them will be in an upcoming video adding a fuse block behind the helm.

I am installing two amps so should they go connected directly to the battery or to the switch?And if to battery to which one? 1 or 2

[@Channel-About-Nothing]

I just did another video where I installed an amp. people will say connect it directly to the battery but I'm not willing to do that. I connected mine to the switch. I'm not willing to risk the amp running my battery down.

[@oma3710]

Van R does it matter that I am installing two batteries. Just connect them to the top right post.

[@Channel-About-Nothing]

@@oma3710 each battery should connect to a different post on a two battery switch. It sounds like you may be installing two batteries with a single battery switch which I don't think is a great idea.

[@oma3710]

Van R I am running two batteries and same exact switch you are. My question is should I connect the amp to the same post on the switch?

[@Channel-About-Nothing]

@@oma3710 I would connect it to the third post not either of the post that the batteries are connected to. That way you can be sure the amp is completely off and you can operate it off your second battery while the boat is not running.

[@jttribe7683]

Hey man! Great video! I did the same thing on a 2018 190sx. I just wanted to double check. When on selection 1 on the switch I have all electronic abilities. Blower, bilge, lights, horn etc. When selecting to selection 2 on the switch i have all the same abilities. That is normal correct?

[@Channel-About-Nothing]

Correct, that's the way it should be installing a switch in this manner.

[@tepot5]

Your bilge pump shouldn’t be hooked to battery #1 , if your switch is on the OFF position your bilge pump won’t work, you should always plug the bilge directly to battery so no matter what position you have the switch your bilge will always work.

[@Channel-About-Nothing]

The automatic function of the bilge is connected directly to the battery. The manual switch side is not.

[@tepot5]

@@Channel-About-Nothing ok perfect!! Thanks for confirming

[@BobChanter]

If it's hooked to "battery #1" it would still get power to the bilge pump as it runs directly back to the battery. If, however, it was connected to the "Common" then it would not work in the off position.

[@satoshione8145]

Exactly the video I was looking for 👍🏼🙏🏻Thank You brotha, Sweet 🚤 👌🏼Full parts list ?? See the switch link

[@Channel-About-Nothing]

I actually did another one redoing some of it and adding bus bars. It has a better parts list also. kzbin.info/www/bejne/jaOaY2uMgLGAaJo
