S2 E1 Installing lithium and AGM batteries (Dominican Republic) 

So true!

THIS!

those Vatrer LiFePO4 batterys have a BMS built into them

Thank you :)

I thought I heard the same thing. AGM and Lithium should never be linked via a bus bar.

You use separate vitriolic baterry charger diferent charging voltage

@@gyropilot1 The discharge rates/properties are different as well. Having an agm in circuit without a dc to dc convertor could at best damage the lithium, at worst, result in a fire.

What I ment you need an isolator victron where you can separate the charging without connecting both bank to same buss. I have agm and a Bomar the alternator and regulator let me decide battery type. In the future I am going 24v all lithium and only 1 agm for starter. I know I have alot of blu boxes to buy to attach. Engine,shore input solar and wind mill . But will be fun

A DC/DC converter would be my recommendation, thats what they're for.

Thank you!

My general rule of thumb is to have the larger capacity bank charge the smaller one. The way Nicole described the system thus far without isolators or dc to dc units and just connected by a bus runs the risk of damaging the batteries and fire. If the lithium system ignites, one can only hope the fire doesn't spread to nearby boats in the yard. If that AGM is in circuit with the lithium, it needs to be disconnected immediately.

Aw haha glad I can help!

Yes, that’ll definitely be on my list of things to do when the boat gets back in the water :) right now I’m prioritizing projects that need to be done on the hard.

Yes! I have the schematic that I can reference. Labeling will make a great rainy day job!

Each sealed battery has one inside.

It is super satisfying. It’s a lot of hurry-up and wait and the waiting part is actually the most painful!

Thank you for watching and commenting!

Haha yea!

Thanks for keeping up with me!

Thank you 😊

Not sure a total layperson would understand parallel vs series. or other electrician like terms. And believe we are dealing with Lead Acid.

no they are new lithiums and they are not connected properly, they NEED to be in Parallel to stay Balanced correctly and also to increase AMP LOAD CAPACITY It needs to 'behave' as ONE big battery , not 4 separate batteries. Especially with Solar MPPT based charging and pulling load from a 3000watt ( 6000peak) Renogy Inverter

Thank you!

Thank you!!!!

Yes, that goddam patriacy at work again I see (joke, please don't cancel me)

Have fun!

That’s a helpful perspective. Thank you

Yes! I had a lithium battery on my old boat, the Columbia 26 I sailed from FL to the DR. It worked great, I could even run the little wonder water maker off my solar!

I definitely could have, now that you bring it up (a couple other people commented this too, I think).

@@SailingArtha you still are very impressive Nicole! Much love🙏

@@CowboyUp99 live player, hate more

Yes, right now I’m prioritizing what needs to be done on the hard but once the boat is back in the water I’ll be working on prepping the boat for a sail!

I didn’t seen any cutting inserts in the hydraulic crimper but that would have been very handy! And yes, I definitely decided to organize the panel in a way that I have some spare switches

I used Carmen Cargo. Flat rate shipping

Yea that’s for sure

Yea I would really like some new tools that’s for sure!

@@SailingArtha Then invest in good and durable basic equipment. It's not as expensive as it sounds at first. A set of electric screwdrivers (fully insulated) and a set of locksmith screwdrivers are available from around $50 each (including tax). With proper care, they will last forever. Now add a set of ring wrenches and a set of open-end wrenches as well as a set of good pliers (pliers, needle-nose pliers in straight and curved versions, side cutters and pliers for stripping smaller cable cross-sections) and you can get good quality pliers for a total of around $200. You don't need a ratchet box to begin with. Although it makes the work much easier, it takes up a lot of space, is heavy and expensive. Instead, buy a set of socket wrenches for the most common Allen screws on your boat. You can also expect to pay around $40 for excellent quality. Then add a simple drill (not a cordless screwdriver, they are always empty when you need them) and a small cutting disc for cutting and grinding (together under $100) and you are equipped for almost all repair work on the boat. You can borrow special tools if you are in a harbor and, for example, you have to install a new hatch or you have to do welding work or generally work with large-scale grinding work on the underwater hull. All in all, you can certainly get by with $450 to $500 for a reasonable and durable basic tool kit. At first glance, that sounds like a lot of money and, if you live frugally, it's enough for at least a month or more of living on the boat. But the investment is worth it and will save you frustration, time and health later on. And that is priceless!

Yea, sometimes it works, sometimes it doesn’t!

I’ll be building a box for the house bank when I’m not longer prioritizing yard projects 😊

Maybe! I had some people tell me that the wires would be smushed though and a cutting disk would be better. I shoulda used the cutting disk.

ya got it did aint much more that counts

A VSR won't work on a lithium system because the voltage is 13.2v so the VSR will always be connected, not just when the engine is running. A DC>DC charger between the AGM engine start battery and the hybrid bank would be a better solution. Connecting the first positive and last negative is wrong and will cause each battery to charge and discharge differently. The way she has these installed is correct particularly with the same length cables.

Calm down weirdo 😂

@@connergiven89 can’t. I’m too weird

creepy stalker

I ended up hiring easily one of the best marine electricians, Brock on S/V Polaris. He did an AMAZING job. I’m so thrilled.

Out of my control, but yea, I’m not opposed to that at all

Please share a photo of the diagram on your RU-vid Community page.

@@sailorpenceI uploaded mine on Community Forum as well

Isnt there a fire risk with being charged with the agms off the alternator via the same bus bar?

@@anonymous.notatall6419 Yes a bit perhaps , but equipment damage is the bigger concern
