Surely the BMS can be engineered to manage the profile better, given that most of the drop ins will be into a 12v system charging at 14.6. I realise that temp sensing and regulators are important especially in larger systems.

Surely the BMS can manage the charging profile?

whinging with style!

Apparently reject cells from the big manufacturers are bought for cheap and packaged up into the odd brands we see giving huge profit margins and bad reputations. Provided the cells are good quality it seems that the built in BMS is the key to the whole exercise, as I was saying lithiums are a common upgrade and an oem fitment to high end bikes, as a group performance biker are very onto technical benefits and there is very little chatter about lithium issues so i would imagine that cheap and nasty brands simply dont survive. In the RV/Marine world the market is huge and the tech is maturing s

Interesting, lithium battteries are a pretty standard upgrade. A typical size is 14 ah so maybe they can afford a higher quality BMS?

I have read mainesails blog extensively over the years and its probably the best yachting resource for lithium conversions and as Ladyhawk infers, complex and expensive to get right. That said, its a very common upgrade for a bike- trade the LA for a drop in lithium. I did it a year ago and its been trouble free. Hence the question for a boat. The short version from the responses is not yet! AGM and Gel al may be useful but in the end the easiest and cheapest option may be replacing like with like.

Whats the issue with windlasses? i would have thought it would be an ideal power source for one

Have used lanocote and the other henley product, its all essential the same stuff- sheep grease but presented differently.

if you use say 30 amps a day then instead of getting a FLA of about 100 or more then you could in theory get a 50 ah lithium. Lighter not too much difference in cost and many times the life

Are they ready for prime time? I see plenty advertised now at reasonable prices that include sophisiticated BMS's, you can downsize the Ah requirement because you can go so deep on the discharge The concern is that they can be a bit of bomb, make the alternator work overtime etc but the advertising is suggesting that the BMS manages that without external temperature sensors. Anyone done it, thoughts? https://www.jaycar.co.nz/12-8v-100ah-lithium-deep-cycle-battery/p/SB2215

legendary!

No one has a bigger boat than you on this board!

Heres Casey Stoner, what a great rider

Italians do it in style, my font is the current Ducati font BN Elements, but yours is very slick

Raz are you sure its plastic and not some kind of GRP? It would have to be a pretty hard material to avoid getting scratched which is pretty unhygenic, which is why I presume most bowls are porcelain. If its a Jabsco check with Lustys but in any case if you cant find a lightweight replacement its not going to lose you any races, one bad tack and all that!

Nice, interesting titanium hinges, the look 3D printed and as you say spendy, im guessing 2 boat dollars?

Theres no limit on posts

No one outside yachting will notice or even care that much if they do. It's such an odd pursuit, carefully marketed to cultivate an association with average NZers but in reality its a competition between extremely wealthy individuals who couldnt give a hoot about nationalism, red socks or whatever unless it provided financial relief! Dalton is doing his job which is to extract as much money from whoever to achieve his goals, be it the Govt (you and me) or the Saudi's or the Frackers- the source of funds does not matter, nor does the location of the event. For me personally the gloss has

Does anyone else feel a bit over the endless posturing?

Next dipstick needs to be longer!

What is this thing "guardrail" that you speak of?🤣 No lifelines or pushpit on a Stewart!

Good discussion, I want to get a panel but since space is limited to an area approximately 1.2 m square on the coachroof I will need one that I can walk on when flaking the main if it is to be permanently fixed. I for boats under 12m that is probably the biggest issue; spare real estate. The alternative is a demountable rigid panel but that has its own set of issues with stowage, so its a bit of a tricky problem if you need a permanent power source.

The so called modern anchors are not that modern anymore but the general difference is a concave scoop rather than convex flukes i.e ploughs dig in by literally making a furrow so they require a bit of runway and seabed composition like a farmers paddock and if you have ever ploughed a field with a wee Massey Fergusan 35 then you know how important soil structure and the absence of rocks are! The modern anchors are all a variation of a digger bucket with differences in degree of concavity, blade area, stiffness of structure etc. The Excel appears to be a hybrid with elements of the plough and

Generally if there is an issue with a rudder its a good idea to remove it and inspect it carefully, consider it maintenance. It will be pretty basic and youll work it out quickly once its off. Rudders dont generally fail when its sunny and pleasant and you dont want to find out that it has a problem when youre smashing home in the Colville channel

As the fuel pump is ok most of these small diesels are easy to work on.
