Moving & Converting Boat Batteries To Li Ion!

[@sterlinghousewashpressurew9594]

Best boat content out there. Brother you're helping so many people get back on the water and saving their wallets.

[@randyosburn533]

Very nice work. The next time you install electrical components, you may want to review how you determined cable and lug sizing.

[@dainperrault585]

Love these videos, always nice to see bits like this make a huge improvement

[@Free_Ham]

Great video. Loving this series. It goes to show how valuable it is to be able to refresh a solid older boat. Especially since new boats are so expensive.

[@yourmedicareguylarrybelt7792]

I have a couple questions because I’m going through this now One, could you have just use one battery for starting and for the house? It appears like you left the former lead acid for the house, is that correct? What is the wrap you used around the wires in the back that looks like pretty nice stuff.

[@BornAgainBoating]

The wrap is this: amzn.to/3B3oQuB We used 1 battery for the house and the starting battery as well and removed the lead acid

[@c.shoefish]

Great video man. I converted my 16' tiller boat to full lithium and I dropped 87 pounds out of the boat, and I can definitely tell the difference. It's also nice being able to run ALL day and not having to worry about it, especially in some of these electric only lakes up here in NJ.

[@josemanuelfernandezsanjorg7042]

Great video! Awesome work! Congrats

[@billwallenstein3387]

Love your work as always. I think I would have pulled the leaning post when we started, my knees don’t move that well anymore. 👍👍

[@BornAgainBoating]

Lol believe me, if I could have I would have, Key West in their infinite wisdom, through bolts the seats in! You have to drill them out to remove that post! Crazy unfortunate

[@Oakleyshooter]

How come you didn't hide the primer bulb in the rear stbd hatch where the fuel filter will go?

[@brucebarnes8039]

That's not were it goes

[@BornAgainBoating]

Didn't think I had the space, probably would have been a good idea lol

[@lb7wade518]

Top notch!! Looks professional

[@RSteel517]

Not sure if you did or not, but making the battery cables long enough to pull the battery out and disconnect would be a nice feature. It would make it easier in the future to replace the battery, or to pull it out and troubleshoot other issues or add new items to the console.

[@BornAgainBoating]

Yeah, I should have done that lol :(

[@etothelij]

Can run gels or lithium ions under the floor of the cab, more wire involved but about 90% less corrosion related issues. (Not leads because they offgas)

[@Englewood_guy]

Very appropriate for me as I have a 1720 as well!

[@fishhuntadventure]

The thing is with replacing lead acid batteries with lithium is that you can’t charge them below freezing. So if you’re in the north east like I am essentially you’ve disabled your boat with the inability to charge the battery - do you want to start the motor that’ll be fine, but then the charging starts and unless the battery protects itself, it will damage the battery. And at what point does it get warm enough to finally start charging? Not everything new is appropriate all the time for everyone.

[@JonQuattlebaum]

Per ABYC Soldering connections is prohibited except a Soldered connection that joins a battery terminal connector can be used if the solder is 1.5x the diameter of the stranded portion. The reason soldering is not acceptable is that it turns stranded wire into solid and will eventually cause strand breakage which reduces the capacity of the stranded conductor.

[@mickemike2148]

Clean install!

[@BornAgainBoating]

Thank you!

[@chadmills4210]

Great instructional video.

[@DanielLann-e9x]

Do you have any input on only using flooded lead acid on a ‘01 merc 90 hp? From what I’ve been told I shouldn’t use anything else, not even AGM, never dual or deep cycle, etc due to the charging system with stator and voltage regulator

[@BornAgainBoating]

Lot's of variables there, here's most of how I understand it: kzbin.info/www/bejne/mnyblIOlbs2efck Lead acid is just super stabile for that old 2-stroke though

[@giannigrasso6424]

hi, can you tell me what material the panel you created is made of? I can also attach the busbar fuse box etc. A thousand thanks.

[@BornAgainBoating]

That panel was made from Acrylic by New Wire Marine: 2ly.link/1z7Rf

[@davidd8435]

Can't wait for the maiden voyage.

[@MrInsanityflea]

For that battery Epoch claim it's not compatible with a stator, doesn't that 90 Yamaha 2 stroke use a stator? (let me go check your lithium battery video)

[@BornAgainBoating]

Lot's of variables there, here's most of how I understand it: kzbin.info/www/bejne/mnyblIOlbs2efck

[@dougwhite2695]

Most insurance companies will not cover you if your lithium ion batteries are not ABYC certified and some require the installation to be made by an ABYC certified installer

[@kelevra002b]

Dumb question but I figured I'll ask anyways to get some opinions. Currently working with a 18ft cape horn, want to reroute the batteries for better weight distribution. We have a center console with a flip up lid and 36 gallon tank mounted underneath. There is room around the tank itself to mount batteries and it is well ventilated. I know possible sparks near a fuel source isn't a great idea but I don't think if mounted properly it shouldn't be an issue. Any thoughts?

[@BornAgainBoating]

There are a lot of boats that have the fuel tanks and the batteries in the same compartments, but yes, you need to make sure there aren't any leaks on the tank and that you can get proper ventilation in that area, which there should be already if the tank is in there already, not sure if that was factory from Cape Horn, I've not seen any of their smaller boats, just the bigger ones and I like them, but the tank should be vented to the outside of the hull as well. But quite a few flats boats, bass boats, bay boats, and other boats do have the fuel tank and the batteries in the same compartment, though most try and build some boxes or something to separate them, you could put something between them or kind of closing off that fuel tank into it's own area :/

[@kelevra002b]

@BornAgainBoating it does have a vent hose running to the port side of the center console to atmosphere. I've been looking at most likely relocating the trolling motor batteries to the forward compartments and then the house/cranking to the center console. Definitely going to be a winter project lol already rewired the WHOLE boat over the summer. Never again

[@seanur2414]

What is the product used to wrap the cables around 5:18 ?

[@fixedgear09]

Spiral Wrap. I want to know what size he used.

[@BornAgainBoating]

amzn.to/4fWkhBR 3/4"

[@hectorrodriguez9713]

What is the product number for the new wire power panel box you put behind the seat

[@BornAgainBoating]

We had it custom made from New Wire Marine 2ly.link/1z7Rf

[@rudyu2767]

I’m thinking of rewiring my boat and adding a new battery set up. Thank you very much. Your videos have been extremely helpful. Thanks again for creating this great content. I looked on the website for the battery you bought for the starter and it states that NOT COMPATIBLE FOR OUTBOARDS WITH A STATOR. I’m not sure why it says that. Just make sure this will not fry your alternator.

[@BornAgainBoating]

Lot's of variables there, here's most of how I understand it: kzbin.info/www/bejne/mnyblIOlbs2efck

[@CT-gc1ck]

I think those batteries epoch sells are lithiums but rather lithium iron phosphate and not lithium ion.

[@mwatkins2464]

I need one of those batteries to take the place of the 3 I now use. Never had a lithium battery before 🇺🇸🙏

[@kerrytodd3753]

It won’t replace three batteries……

[@Laserman99]

Moved my engine battery to console so I could put dual batteries in back for my Minn Kota trolling motor. Wish I would have moved all three for the weight of batteries and four stoke engine puts my self bail at the water line.😢

[@wmp89]

I thought you can't use lithium for cranking battery because the alternator on motors isn't compatible with charging requirements?

[@BornAgainBoating]

Lot's of variables there, here's most of how I understand it: kzbin.info/www/bejne/mnyblIOlbs2efck

[@bimini99]

Will the alternator properly charge a lithium battery without a BMS ?

[@BornAgainBoating]

I don't think that would be very safe, lithium can be super dangerous if it's not done right. You gotta be careful with super cheap lithium they can be dangerous, here's how I understand the lithium charging issues: kzbin.info/www/bejne/mnyblIOlbs2efck

[@Dbars19]

weight is good for boats unless its some sporty bass boat.

[@JohnColeman-ul5rj]

I bought 2 EPOCH starting batteries. One has already stopped displaying on the app and have had 0 customer service. No reply from email, their chat, or FB page. They suck. I will be looking for another company for a 36V trolling motor battery.

[@JohnColeman-ul5rj]

They called me today and are addressing the issue!!!! They said they have been having some issues with communication but are on the path to addressing all their customers!

[@mrgoldfpv7331]

If those batteries have integrated BMS board and that thing stops working in the ocean.

[@tavaftw]

What gauges are these battery cables?

[@BornAgainBoating]

4 gauge, The Yamaha's probably 6 Gauge

[@AVMAR]

The Epoch batteries are great batteries the free replacement warranty is 3 years. A $200 group 24-27 AGM deep cycle battery for that small 90HP engine would had made more sense and would last a good 5 years and you don't have to worry about the BMS disconnecting for whatever reason and frying the rectifier, most older outboard engines charging systems are engineered for use with lead acid batteries, not lithium.

[@acme9538]

Yeah . . . even my new Yamaha F70 4-stroke can have issues with lithiums just as you say, so I passed . . . . IMO they're great for trolling motors, but it's a lot more complex when you are using them as a starting/ house battery.

[@warren6172]

They have to be real close to making them safe to charge. I’ve had a lithium battery in my motorcycle for years and no problems. And it cost the same as a replacement lead acid.

[@AVMAR]

@@warren6172 LiFePO4 batteries when left fully charge for a long period of time tend to lose some of their capacity they also need proper maintenance charge/discharge cycles and most people won't do it correctly specially when used as a dedicated starting battery.

[@fishhuntadventure]

Some truth there, but a couple things are not necessarily so. A lithium battery designed as a drop in replacement for a deep cycle lead acid is gonna work fine with a traditional charging system.

[@MP-qn1jw]

Aluminum wire? I no like. Thanks for the video anywayz...

[@BudgetBasshead72]

Can that new fancy battery take 17.9V through its teeth when my 70hp evinrude is iddling lol

[@hansgruber2509]

What a dumb move what does that battery cost 4X the price and what does it get you? A smart move is to have 2 batteries, lead acid cheap and reliable

[@BornAgainBoating]

You the man!

[@mulletoutdooradventures6286]

I love the people that think they will end up dead in the water using lithium. I switched over to full lithium last season and the only way you will have an issue is if something were to go catastrophically wrong with your electrical system. You have to make sure your connections are solid and you'll never have an issue. I love them. I lost almost 80lbs of weight between both and my run time when fishing at night is ridiculous. I really wouldn't recommend using lithium on older motors.

[@kerrytodd3753]

Hmmmm, the main reason you moved it was because of the water……water and lithium doesn’t like to play together.

[@jonblair5470]

Isn’t it pronounced “E pock”??

[@BornAgainBoating]

I didn't think so but maybe I'm wrong :/ lol
