findhorn,
We have a 8Kw generator and so far have only one seasons experience without solar. We also took an option from Jeanneau to change out a water tank to a diesel tank as we have both the generator and the larger 110 Hp motor and with a desalinator it is easy to make water but not possible to make diesel!
Last season we were four adults on our maiden delivery voyage and each morning at anchor we chose to use the generator for about one and a half hours to fully charge the batteries from the previous days usage, heat the water in the water tank and make another 100 litres of water from our water-maker to top up our small 400 litre water tank. I believe with solar, I could reduce this at anchor to every other day especially as in future there will only be two of us on the boat most of the time.
Every cruising couple has a different lifestyle, we are energy hungry, we have fresh water flush toilets and like long hot showers. Every day we use a coffee machine, hairdryer and as mentioned before run two fridges and a freezer. We tend to keep AIS, VHF and navigation instruments running while at anchor and we like our music entertainment, with LED lighting we are lit up at night like a Christmas tree, so I don't think we will ever be totally reliant on solar unless we are passage making when we can run our water maker off 12 volts and our motor can heat the water tank.
Incidentally although our domestic battery bank are Lithium we still have AGM batteries for our starter motor, bow thruster and electric bathing platform. I do not believe Jeanneau spec a different alternator as the Lithium have their own built in BMS.

also I asked the seller to NOT INSTALL a separate charging plug and also put a bigger BMS 150amps ( additional charge is 20USD for the bigger BMS)
and finally I will put in the bin all my wet batteries on board...

should be - but I want them in UK - to test all properly and will ship with other stuff to my boat later in the winter...
e.g. I want to be sure about do they do exactly what it say on the tin e.g. 120AH, 150amps continuous and 10v min and 14.6 max - I use my battery bank to heat water using my invertor and for bow thruster and anchor and need to be sure that it can survive in 150amps for 30min and that the BMS is doing the job that is expected

Not sure if another discount campaign is scheduled ( like the annual 11/11 ) in the foreseeable future on Aliexpress ? Will check it out as these sell offs usually offer a substantial price cut . I been around quite some time , years in fact , on Aliexpress you see. Also bear in mind some serious custom tax will be involved to import these batteries. Regards

Regarding links: It looks like they doesn’t work opened in AliExpress app directly but work if copied in browser (like Chrome) Strange... I’m also thinking about LiFePo route just didn’t educate myself sufficiently yet. Nevertheless it’s quite $$$ if something goes wrong. Lead-accid is still something you can not screw up completely easily. There are also big problems in any attempt of mix system. As far as I’m concerned it is either all in or stay on lead. It’s cheaper that way 😉.

I have a mastervolt dc DC charger to charge my forward agms using my lithiums. I ended up with 1120ah of lithionics and about 1100w of solbian solar. 2 victron 12/3000/120 inverter photos.app.goo.gl/YZv6xncC821Rquqn8.

Nice project on Coder. I’m too little educated in electric systems to follow all the gear you showed on photos. I think I’ll cook myself nice 600Ah bank of 3x200 LiFePo @12v and add one 60Ah for start and another for BT and get rid of lead as soon as my home bank goes south-ish. Still got a season or two in them. Of course some sort of start assist will be required I think. I have Victron multi 2000/80/230 which has lithium profile and is configurable so no sweat there (at least hopefully)

Before buying cheap Chinese made batteries you might want to check this out.

alenka,
many thanks for posting the link. It just goes to prove, time and time we see this, "you only get what you pay for" The idea that these cheap Chinese imports are value for money is a fallacy or at the best, they are not built or designed to last.

I also tend to doubt that many will have the required CE approval. Which makes me wonder how an insurance company will look at a claim (fire) if it is caused by an unapproved import.

I agree with you. However, after the end of this year if the government cuts all EU laws and regulations at a pen stroke as they have promised we could see a flood of poor quality items entering the Country. It will become a nightmare to choose a quality product or we could just stick to the European manufactured items that retain the CE approval!

we cannot just say - when you buy from China and it is bad : for example I ordered a big batch of li batteries (18650) from following link in aliexpress and they are better then very expensive panasonic - panasonic hold about 2600mah and the china one 2800mad on fraction of the price www.aliexpress.com/item/33022373013.html?spm=a2g0s.9042311.0.0.27424c4dHxZ5Znpicture of actually capacity attached:

Vasko, we are not saying just because they are made in China they must be bad, we are just suggesting that without stringent controls, regardless of where they come from, there is a greater risk of purchasing shoddy goods.

I think the only way for me to buy chinese LiFePo battery would be by bits and pieces meaning cells, BMS, cabling all seperately. This is the only way you can know what you have. You need to be knowledgeable and skilled in the area of course but not an expert. Regarding insurance - do you realy think all your gear and all installation is made acording to standards? Guess not so insurance companies will always have a picnic if they decide so. Yes, bateries are mission critical but not nearly as much as a loose wire.

Hi I replaced the three house batteries with three Transporter Energy (Battle Borns name in Europe) 100amp lithium ion units together with a Victron Energy Multiplus Charger inverter. What a difference it has made to my 42DS, I have power well in excess of what I hoped and can even use my electric winches when close tacking to windward which I could never do before without alarms ringing for the low battery charge. So in my opinion do not think about it too long just go for them. Phil

Phil,
Do you have any low temperature protection? Battery heater pads, etc??

No I don’t just a straight forward swop, Transporter Energy based in the UK came up with exactly what I needed for the installation and my local marine electrics engineer fitted it. No one has ever mentioned anything about heat pads, mind here in Jersey we rarely get below 0 degrees C. Certainly no one has ever flagged it as a problem, I also sail throughout the winter and everything works equally well as when it’s 30 degrees in the summer.
