Lithium & Old Outboards

[@wayne558]

I'm no expert, but I'm staying with a lead acid starting battery for my Mercury EFI v6 2-stroke. I don't need 5 MFD(s), $224 dc to dc charger, $699 lithium dual purpose battery, 4 extra circuit breakers, just to catch a fish. Plus if you remove too much weight in the bilge, may have to buy a different SS prop for about $750. Interesting video though.

[@ruaraidhmcdonald-walker9524]

All in the regulator!! Low internal resistance LiIon batteries will take much more current ALL of the time when compared with lead acid so the regulator really needs to be li ion capable or it'll simply overheat! External regulator is the way to go for inboards but much harder to achieve on an OB. Great video!

[@Puma-cv2vk]

You should make a video on installation and testing

[@MrInsanityflea]

This is excellent, thank you! This is the information everyone is looking for before diving into lithium batteries. Looking at my charging system the diagram shows stator -> 2 voltage regulators -> starter solenoid -> battery. The voltage regulators have 5 wires, two yellow - stator input, two red - dc output and one grey wire for the tach. Looking at that, looks like I can't separate charge voltage. I'm happy to just keep running the factory spec.

[@rdsandy11]

I parallel a small Pb acid, about 7 AHr found in small home ups with my LiFePo4 to prevent any issues with disconnected batteries.

[@TheCornucopiaProject-bd5jk]

A good trolling motor lithium battery does a fantastic job. For bigger engines you obviously need bigger and more batteries. Always read the spec sheets.

[@JohnColeman-ul5rj]

I use the 2 EPOCH starting batteries on my twin 2005 200hp HPDIs without issues. WOT I have 14.7V on the stator. The BMS has a shut-off of 15.7V, which so far I have no issues.

[@fillingteck2726]

Very good subject for old engine owner

[@jamesroseberry2329]

Great video on batteries

[@BornAgainBoating]

Thank you!

[@scottraven8404]

I know you are focusing on the salt water side, but you need to research the bass boat side and see what lithium batteries they are using. Epoch duel battery you are demonstrating along with other brands works fine with Hpdi with stators. We actually want more voltage just to run graphs up to 20v for best imaging.

[@BornAgainBoating]

Yeah, the bass world is something I don't know alot about, you guys really load out them boats with a ton of electronics and what not, and they only ever have one engine so that's a complication lol

[@michaelpowell9164]

This hurt my head.

[@masteryoda9341]

At Costco, they got a h8 interstate amg with 900cca , I’m currently eyeing it, with a three year warranty and selling for $169. Vs buying the interstate marine 750mca lead acid batterie with a 12 year warranty for $98. I’m looking at adding a few electronics and figure the weight difference is less then 5 pounds, and should give me more amps hours with more chance to start the 1996 Yamaha 9hp 2 stroke.

[@MrBdogg317]

I have a Yamaha hpdi ox66 3.1l 225. So I was told I could use ionic lithium cranking battery on my motor with out any issue. I don’t have a rectifier on it. Was I told wrong?

[@BornAgainBoating]

Well, it sounds like a couple of things are not clear, sounds like you don't have an HPDI but do have the OX66 which would be the 3.1L Vmax, and they do have rectifier regulators. Not sure about the output and whether or not it's stable enough to put on a LiFePO4 or not :/ you have to see if it's stable, if it's not or the voltage fluctuates, you need the dc-dc converter

[@rudyu2767]

This video was gold. I have 1 question. How do you make sure that the stator or alternator senses the battery? Is it the ground wire coming back from the battery? I have twin Yamahas hpdi and I’m rewiring it because now they share 2 batteries. I want to put each motor on their own battery.

[@lakeratatouille]

You almost did a Kamala salad on the stator, stator unburdened from what has been. Btw thank you for your professional explanation of this been wanting to dive into this

If you find Kamala less straight forward than Dump you shouldn't be allowed to go on the water near other folk.

[@gdebrango]

So I'm staying with lead on starting but my second bank I want lithium. I'm concerned about 30 amp being enough. I'm understanding that you go from lead acid to DC to DC charger. How would you wire multiple DC to DC chargers to increase amperage. Much appreciated with this video

[@johnnygolden7401]

Those chargers would need to be ran in parallel. Amperage is additive in Parallel. Voltage is additive in series. Basically, you would need to apply the voltage from the engine to each of however many chargers you want to get the desired amperage. IE: the example he gave was using 3 of those 30 amp chargers, wired in parallel, that would give you 90 amps of current available.

[@simonadventum]

I want to use a LiFeP04 for the electric trolling motor and other electric stuff on my bass tracker, could I still use the old 2 bank battery 12v charger? I have another lead acid battery just for the 40hp 2t Evinrude motor

[@BornAgainBoating]

No, you won't be able to use that battery charger on the lithium, unless it as a lithium setting, but most likely it doesn't, and depending on your trolling motor, most likely it's not 12V, could be though in that case it would work if you can set the charger to charge the lithium :)

[@simonadventum]

@@BornAgainBoating it doesn't have a lithium option. The electric trolling motor is an Minn Kota Edge 45 lb

[@djpat5998]

You can make your own lithium battery out of lead battery case. While you're on here look up diy lithium battery and all you need is good BMS.

[@BornAgainBoating]

That's over my head lol :)

[@robertcelebre7247]

Great video very informative

[@timrainger8908]

Good stuff!

[@jims4539]

Would using the DC/DC charges help with LA batteries? Seems clean voltage would help all systems.

[@BornAgainBoating]

Nah, LA's are super durable and stable :)

[@jerryq1000]

I definitely have a plain Jane fishing boat. '06 Yamaha, 2 cycle, 50 hp. Never thought about using a lithium battery for a starter...have considered it for the 24v trolling motor to replace the two 12v lead/acid. I'm pretty sure my electronics run off the starter battery...other than having to replace the onboard charger, do you run into any situations like mine? A hybrid if you will...

[@BornAgainBoating]

Plenty of people do that, you just have a charger for the lithium battery that is your trolling motor battery. You won't need to charge it with your engine, that thing will outlast you on the water and then you just charge it the night before going out, they charge up super fast! And yeah, all the electronics should be off your starting battery, you're probably using it as the house and starting, same as what we are here too, super common on small boats

[@jerryq1000]

Thanks!!

[@davidday6426]

Same situation here. Thinking of loosing 200# and get them for the 24v minnkota. I don't think my 3 bank Pro Mariner will charge Lion though. IDK might need a new on board charger.

[@GreatestGenerationCausedThis]

I use the LiFePO4 to run my electronics(radios and chartplotter). I just charge it as needed off of my shop power. I have 3 layers of over amp or short protection between the battery and the electronics: A trip/reset 50 amp breaker I use as an on/off power disconnect, a fuse block to feed power into and of course inline fuses for each component. I also added USB and cigarette lighter type outlets to charge or run additional electrical devices as needed. Everything else, engine, lights , trolling motor, pumps, anchors is run off of lead acid and deep cycle batteries.

[@thecableguy1128]

Did you see the information about the lithium batteries in your instructions with your minn kota terrova? I seen something about it in the instructions but I haven’t read it yet. I will be using gel batteries with mine.

[@reefslayer21]

Let’s say I am using an ACR and want to get a lithium battery for the house, would I put the dc/dc charger between my relay and the house battery? I’m running a 200 hpdi with an optima blue top for the starter

[@randyosburn533]

Still using lead acid batteries in my newer Cape Fisherman right now. Too many issues associated with using lithium. Juice is not worth the squeeze.

[@rivera4413]

Do you know if a f150txrd yamaha is good to use with a lifepo4 without buying any extra stuff? It's an 06

[@BornAgainBoating]

That has a stator whether or not the rec/reg will work, I'm not sure exactly :/ probably be best to use the DC to DC, someone just said they've been using lithiums with twin 200 HPDI's though so it's hard to tell, like I said, it's confusing lol ;/

[@rivera4413]

@@BornAgainBoating thank you brother appreciate everything you do!

[@Skits_Missions]

People sooo over think this. I have been using lithium LiFePo4 for 2 years in both my large boat, 225HO G2 - crank hybrid lithium charged directly from outboard, house 200ah battery charged via 30amp victron DCDC charger and solar. This boat has a heap of power draw. (Fridges, 2 x displays, lights, stereos, radars, etc etc. Also have 36volt lithium Minn Kota setup in the same boat. Over 8k in battery’s. Also hybrid lithium in my small boat with 40hp E-tec. Hybird crank lithium is designed for charge direct from most chargers. But yes good video to explain the older setups.

[@bobwhite9670]

Easiest thing to do is not use lithium on a 2 stroke. I run 03 175hpdi on wally world cheapies and have zero issues. Every two years swap em. And wally has a two year guarantee or free replacement so you figure it out...

[@brianpino7274]

Will these charge on the evinrudes non g2 series?

[@cooletti]

install a DC to DC charger with those old Outboards ?

[@MrSilviable]

Did you do a video on the dif lithium type batteries and why they’re no bueno?

@@BornAgainBoating you da man

[@UltraMagaFan2]

Personally, I don’t see the need to do this conversion on a small boat. I think lithium batteries are overkill. Lead acid batteries are more than sufficient enough to run a 12 volt trolling motor and start a 90 horsepower outboard.

[@Boaters_hub]

How do i get one of them shirts😂 i have see you wear them for years. I am afraid to use lithium because i dont know enough about it. But it seems that power charge regulator is the ticket to using one. 👍

Batteries are always so dramatic, just look up “how to make your iPhone battery last longer” . There so many dances and rituals they say to do

[@manuelfuertes5875]

How save are they . I've seen alot of videos batteries catching fire for no reason

[@matthewwhite8129]

Lithium iron phosphate are safer than lead acid, they are completely different from nmc or any of the nickel cobalt chemistries. Even in an over charge failure situation they may smoke but they do not reach combustion temperatures.

[@BornAgainBoating]

Yeah LiFePO4 are super safe, it's the other make ups that have the harsh thermal run away and catch on fire. That's why it's so important to stay away from cheap lithium batteries, even the ones that go in your impacts and stuff, seen way too many of the cheap stuff catch on fire because they aren't put together properly.

[@blankrobber]

Don't care what's in front of the LiFePO4 to clean up the current. If the engine relies on the battery I'm not using a battery that has a BMS. Period.

[@JaneDoe-qf4xb]

Obviously I need to do more research...... but ... why? Yes, I am a total noob and probably part of the population that help battery setups become even more dangerous xD

[@blankrobber]

The cells of LiFePO4 are fine till one of them drops more voltage than the others. The BMS will usually shutdown discharge in this case. Not so much safety as in fire hazard but reliability that makes lithium batteries increasingly less desirable in this boater's opinion

[@JaneDoe-qf4xb]

@blankrobber right, that makes sense even to me! ^.^ thanks for responding, I'm with you!

[@blankrobber]

@@JaneDoe-qf4xb I'll use LiFePO4 for a trolling motor. They're light and energy dense and won't spill electrolytes so the advantage is obvious when they're in the bow. But for critical systems I'll stick with the tried and true.

[@jaytua730]

I have watched all your videos since your channel inception but this video is the most confusing content I have ever seen. Maybe have some graphics for such a technical subject.

[@BornAgainBoating]

Thank you! And my bad, sometimes I lose track and miss opportunities to explain things better without the tech talk lol :)

[@jasonmiller1325]

He is saying that these batteries have a circuit board inside of them that can get fried by the old style charging systems that these motors use

[@dylantaylor8931]

@@BornAgainBoatingI don’t agree with the original comment but I do already have a good understanding of 12v dc systems. It was interesting to hear it explained in an outboard motor context

[@boatcrafterscollective]

lol. “Graphics” If you need graphics then you probably shouldn’t be working on your own boat so maybe go watch a Mr. Beast video instead.

[@daveconrad9698]

I was under the perception that a lead acid battery would still be required. Even with the Orion. I can’t say that is an absolute, but makes sense that the stator would charge against the lead acid and the Orion charges the lithium which supplies house loads. This is how I intended to add some house capacity to my setup, which currently has two starting batts(twin engine) and a house batt. I want to add two more house batts and eliminate one lead acid. This will give me approximately 6 times the usable power I have now for house loads. The Orion can charge in either direction, so the lithium bank could be also used to charge the starting battery. Again, I may be off base, but I did not think we could or would want to run the charging circuit directly to the Orion as a BMS cutoff could still create a disconnect situation. The lead acid acts as a buffer to all of this. It would good to hear from some experts in this field.

[@L3Dhelpguide]

This should be good......

[@qzyyyy1]

All these rumbling and it is just install a dc-dc charger

[@joebruno2437]

Why two breakers?

[@AVMAR]

Well your're all over the place on this one, Those dc to dc chargers are meant to be hooked up to a lead acid battery/starting bank then its output to a lithium battery bank also using that older model dc to dc charger with a 90HP is really not a good choice
