This is great! One question - I assume you did the battery-battery charger because you've got effectively a "low-output/dumb" alternator, and this was the easiest "plug & play" option...? As I understand it though, one big benefit of lithium when off the grid is the fast-charging ability you could get from a high-output/regulated alternator. For example on ISBJORN, which has just under 1,000 aH Lead-Acid AGMs, we can blast out 220 amps from the alternator, but only when they're dead. As soon as voltage comes up, amps go down, so the charging time extends the fuller they get. But with lithium, I can go full-blast right til their full, right?! So like on ISBJORN, that battery-battery charger would be less than ideal, especially since I've already got the smart regulator that has a pre-programmed lithium profile. Am I understanding this correctly?

@johanpren 5 жыл бұрын

If I understand you ( and the video) correctly, I think the lead-battery only really come into play when there is a sudden shut-off from the bms. Then it buffers the return current. Otherwise the current just passes it and it will not slow charging down.

@joarsvensson4968 5 жыл бұрын

Yes, you're absolutely right. The internal resistance in a LiFePo4 bank is not as high as Lead-Acid/AGM, so it can take much higher charge in general. If the DC-DC charger is powerful enough, it won't matter much if you charge using that or directly from the alternator. But most DC-DC chargers I found are rather expensive for a high Amp spec, so in your case, the alternator on ISBJORN would most likely work just fine instead (if it's setup for LiFePo4 that is).

Hi Andy, Its a good question and interesting for your particular situation. If i remember correct you have some type of advanced regulator with the alternator? If this is the case you might be able to change a few small setting and it would work just fine. Would need to take a look. Ryan

@markhooper3485 5 жыл бұрын

Yes, BUT - it's more than capacity to absorb amps. Max voltage is a big issue, most dumb regulators may allow the voltage to exceed the cut out in the BMS wired into the top of each battery, and if that battery is the only thing connected to the alternator, when it cuts out you blow the diodes on the alternator and are now left sending the alternator for rebuild as well as shipping the batteries back to the factory to have the BMS replaced. Expensive, and slow, and you're dead in the water. Other big issue, and one rarely talked about, is float charging. Lead acids/spiral/gel/AGM will tolerate floating at a higher voltage. LiFePO4 do not. One of the big characteristics of the charge profile for lithium is that after reaching max charge, the battery must be allowed to run down to between 30-50% of charge before reinitiating charging/float. Most dumb alternators will happily keep floating at 13.7, rapidly killing the lithiums.

Thanks for your clear advice. A few things I noted; Very important the battery parallel connections be of equal length between batteries to ensure the same resistance from each battery. It was not an issue for you as all your batteries were next to each other and you cut your own cables but some may be tempted to use an existing cable of different length they already have. Another thing to point out is that when disconnecting batteries always disconnect negative first and when reconnecting batteries connect negative last. André

A great video Ryan, well done. I had to chuckle about those Victron charge profiles though because I use altered ones depending on context - aiming at 90%SOC in port but always 100% heading into night during passage - you never really know what the weather brings tomorrow and I hate burning fuel to charge batteries. You touched on a couple of things that I did differently; not me correct making you incorrect, just different. My alternator charges only my LFP house bank, partly because charging LA beyond 80% is ridiculously slow. I switched to a Balmar alternator/external regulator to charge much that hose bank faster (fuel is precious during passage). You touched on alternators but I took that step. My LA starter battery is maintained solely, by DC-DC charger from my house bank, Sure, that means if my house bank suddenly vanishes then I die - but I'm over that. But it means that a single dead battery can easily just sit out without affecting the others. I'm also happier because this batteries can weld metal if you drop something on them. About connecting in my 4x100Ah LFPs, I went the Victron approach using a "Power In" to provide battery busbars, with a fuse for each battery, on top of the same sort of distribution bus bar arrangement. I didn't let my LFPs just sit "quietly" at first because their internal BMSs communicate with each other to give battery to battery levelling. And it works! I interrogated the BMS array that day, a week late, a month later again etc and the internal pack voltages are always nearly identical. The only thing I'm reticent about is that by windlass draws from my house bank as it did before but I'm on passage mode, at Panama on my way to Australia from Europe so that can wait until after I arrive and switch to fun sailing. An observation about my Victrom 100/30 MPPTs and I have one for each 305W solar panel. The fact is that they are just insane, never performing in concert under the same conditions - and it's anybody's guess as to which one misbehaves. Just crazy.

I'm looking to also install LiFePO4 and I really enjoyed your video. My design is going to be almost identical to yours, but I'd change one or two things. First is I'm planning on keeping the start battery separate from the house bank side but I'm still going to run the DC to DC charger like you're doing. The difference I'm thinking of doing is adding a toggle switch to the signal wire back to the ignition so I can shut off the charger if needed or if I don't need that extra power going to the house bank. The Alternator will still be connected to the lead acid starting battery so it's still connected. The other thing is your battery crimping should be more of a compression of the lug onto the wire in stead of a one sided crushing force. Better crimping tools will be marked with the lugs so that you get a nice even press and compression of the wire. Thank you for the very informative videos!

I am missing an important safety feature in this video. There should be a fuse installed as close as possible to the batteries, to prevent fire in case of a short circuit in one of the wires connecting the battery. It is enough to have a fuse only on the positive terminal. Do you have one installed and if so where? I find it dangerous to tell people to do a battery installation without mentioning the importance of the fuses.

I've been looking at a boat recently and planning on upgrading the electronics (radar, solar etc) and new batteries is one of them. Currently it has 3 Lead Acid House batteries, 1 starter battery and 2 fridge batteries. I was thinking of upgrading the House batteries to Lithium as there isn't a huge amount of space for lots of solar as I would need a frame and the transom is quite narrow.

Thank you for another excellent video. We have more and more clients interested in getting LFP batteries in their RVs. I have heard that the cold can ruin the batteries if they are not warmed up properly before using. In the video you mentioned that they are good for cold weather. I just don't want to recommend something that I don't have proper knowledge about. I would also think that a B2B would be needed as the alternator on the tow vehicle could do similar damage as on a boat. Thanks for all the great information!

I fitted six 12v, 1kWh or 80Ahr *SUPER CAPS* in parallel. My installation is exactly the same as described here. Victron DC to DC Charger set to 13.4 volts. They have a 1 *MILLION CYCLE LIFESPAN* or factory recommended lifespan of 45 years, they're non toxic, can be safely discharge to 0 volt and stored at 0 volts indefinitely, they're non flamible, can never explode, they are 99.5% efficient, and safe to transport by air. They weigh ± 15 kg each. We run an 80L deep freeze @ -19⁰C and fridge @ 2.5 - 4.5⁰C 24/7/365 plus lights, windlass too(1200W or ± 100amps). They also run nav station, auto pilot and bilge pumps. They start our 2000cc(50HP) Perkins diesel on a dime with change to spare. We've never seen them below 12.8 volt or 80% SOC and are normally fully charged by lunchtime and on successive cloudy days they'll charge to ± 95% SOC. We're charging with 2 x 330W pollychrystal solar panels. We'll change these to monochrystal though as they handle shadows better. We live aboard permanently and have had them on our 45ft cruiser for 3 years and they're functioning at 100%. They're also available in 48 volts. These are the best things since sliced bread. Two could do the job but if enough is good then more must be better...no? 😁👍🏻

When I was a boy I made an electric hot dog maker. It was just a bunch of railroad spikes in pairs nailed through a board. About six pairs. I ran house current to the first pair and then from nail Tek nail to the back now. As you’re saying in your video I ran the wires the hot in the cold to the first pair. I found that if I Try to make six hotdogs, one hotdog across each pair of nails, the first pair of nails cook the hotdogs very quickly the second pair let’s quickly the third pair even less quickly and the last pair didn’t cook at all. I bet you could’ve put both hands across the nails on the last pair without getting much of a shock. This was about 1955. Why boat manufactures didn’t know this is beyond me. I’m sure they did. The issue was that the boat buyers didn’t know!

Great vid! One thing came to mind tough. I was thinking that lithium battery bank should only be charged via battery to battery charger. In this setup inverter / charger loads only lithiums. That ok because engine starter battery is assumed to be full, because it is utilized on moments, and it is loaded then first. And finally to the question. Before you did this lithium upgrade, alternator charged Both battery banks. How did you disconnedted the original setup of Both banks? I am planning also Similan upgrade for Jeanneau boat. Just thinking last considerations..

A peek into the past is also a peek into the future. Germany lost 1/2 of it's PKW4 tanks to batteries in parallel. It was a good thing. In the morning, the tanks could not start and dead batteries could not turn the turrets. Yachts and semi trucks are often supplied with isolation switches. They allow batteries to momentarily tackle huge discharges such as starting, then be isolated for separate charging and storage. If i am going to buy two big 12 volt batteries, I'd instead buy two 6 volt batteries to use in series. They don't squabble in series. One gentleman on youtube yanked his electrical project, and posted a new article when he learned the right way he should be encouraging. When things go wrong, disconnect every single battery, and charge them individually. Don't leave anything in parallel. Fair seas, Maties.

Nice overview you provide Ryan. What I do not understand is the function of the B2B charger. The Li batteries are able to be charged at a much higher rate than SLA's. When all the charging is done via the SLA, will that battery not act as a hurdle for the Li and hence slow down the charging to a lower level than would be possible for the Li. I assume that quicker charging of the Li is better than slower, to minimize engine hours or maximize available output from the solar panels. Might there also be a temperature issue for the SLA battery? Would you care to explain when you have time and opportunity?

I am studying and trying to learn as much as I can there are so many choices at very different prices. A question that I would have will the three batteries to run all of your load with all of the boat systems,camera gear, laptops, and an electric heater ate the lytham batteries that much better that much better? Thanks for the video I enjoy your channel so much I can count on you to be technical stuff and for Sophie to lighten my day with her humor. See you the next time and be safe and have a fun day.

Hi Robert. Yes these batteries would be able to power all of the items you list plus more. Thanks for the kind words. Ryan

This two part series was a great explanation of Li Fe PO4 vs lead acid. When you gave your cost comparison, did you include the cost of new cabling and new crimping tools?

@RyanSophieSailing Жыл бұрын

No, not really. Its a very valid point though because that can add up quick.

Thanks for getting back to me Ryan.. My IP 35 is still in the Carribean at SXM For now, I’m gonna stick with my original 60 amp alternator and A 2000 watt Honda generator

I’m sure someone else mentioned this already aside from being a great video the thought occurred to me that the whole or the space underneath of the old battery box might be there to catch sulfuric acid if for some reason your battery would become damaged and it were to leak out. I don’t know if that’s why it’s there but that was just a thought I had

I think its just a construction thing. Not really sure either... was not expecting to see it when i pulled the old ones out. Ryan

Wow! Great video! Do you really run your hot water heater off 4x170ah lithium batteries? That is an amazing game changer!

hi Ryan, i have pretty much the same setup as you described in the drawing. i have my starter and housebank batteries connected to the alternator through a diode bridge. in order not to fry my alternator after installing a lifepo4 battery, i was wondering if it is a good option to connect a DC-DC charger between the Alternator and the LIFEPO4 battery instead of placing it between the starter and the house battery bank?

Hi Thanks for your videos they are great. We have 2007 Beneteau Oceanis , the same as your’s and about to add lithium batteries and Victron multi compact 12/2000. Where did you put your multi as no room in rear berth battery area?

Ryan - not sure you are aware; I am seeing alot of negative comments online (Amazon, et all) about lack of customer support at Dakota Lithium. Also saw the start of a tear down on the battery, where the short circuit test failed...

Great both videos!! One question: Can you have 2 or more batteries groups separated but in parallel? example: 4 batteries in one box and more 4 batteries in other box (2 meters distance) connected with the first box.

@SoundzAlive1 2 жыл бұрын

Yes you can but check that your Lithiums can accept being connected in series or parallel as some won't. The only other thing is when connecting a bank ensure that all the cables are the same length to keep the resistance the same to each battery and to each bank. The banks can be apart some distance. Best to use one of these to protect your batteries. sterling-power.com/products/alternator-open-circuit-protection-device?_pos=1&_sid=272ee4f3e&_ss=r André

Hi Ryan, very interesting video. I do have a question in reference to the 12V/12V charger to charge the lithium battery service pack from the engine AGM battery. I have Mastervolt on my boat and I know the Mastervolt Magic that is made to achieve this charging job. Problem is that Mastervolt Magic only exist in max 20 amps witch is a bit low compare to +/- 80 amps that the engine alternator can give. Can you tell me what alternative to Mastervolt I have for those 12V/12V chargers? Thanks for your help, Regards STEFAN

If the charger is set to charge on a Lithium profile. Will this be bad for the SLA. Or do we now need 2 battery chargers when connected too shore power?
