Re: 100AH lithium battery holds MORE power than 100AH lead acid??

Likely the most expensive cell out there


Evidence to support your claim?

Well if you only have eyes for one brand you are likely correct

Re: Average costs of land living to boat living

The above are my thoughts exactly

Our vessel is 100% self sufficient and we know how to cook and do it well
All appliances are 240v same as a house and similar amenities, if not better.

And that's why, after owning several sailing boats including cats we went for something big enough to not need a marina.

Re: Best boat for cruising

I'm mad on multis and built a few but efficient hulls aren't the best load carriers and as you point out, cost a lot.- $250k is not what I'd consider a lot for a decent multi

Re: What Do You Miss the Most? What Do You Like the Most?

My Burgman 650
Got that bike exactly how I wanted it and enjoyed riding every day and then this bloody boat forced herself upon me.

Oh dear, zombie post.

Re: Does a genset still make sense?

Don't like them either
Terribly inefficient use of resources in my eyes and I have a tough time understanding why anyone who actually knows boats or wants to be at one with nature would go that way....

Re: Does a genset still make sense?

Can't really compare you're 40 ft to a couple of hundred ft of luxury super yacht
Also consider that they have several full time staff on board, I daresay fuel is a small part of the overall bill.

Nope
Less is simply, less

Re: 100AH lithium battery holds MORE power than 100AH lead acid??

Do any cruisers that have nice things and a requirement for lifepo4 have a battery bank that small?

True

But that requires other electronic gadgetry like a balmar smart reg, Wakespeed etc etc to control charge and temp of alternator
And you also have the issue of the starts not getting charge...

Re: Is there a way to glue Starboard?

Anything is possible I guess
But if wanting to keep busbars the same length
Compression of cells the same
And easily movable
A single box is required.

Re: Strange behaviour at 3.4V always a different cell pack shoots up to 3.55V, rest 3

Have you turned it off and on again?

I had something weird happen like that a while ago
Unplugged BMS and plugged it back in again
Problem sorted

It's how you get 24v batteries from 8 cells

Re: 100AH lithium battery holds MORE power than 100AH lead acid??

The bit you're not getting is that electric vehicle batteries that catch on fire are a different chemistry to Lifepo4 used in boat house banks

MDF even cheaper


Small standard sized batteries you are probably right.
But nothing commercially available to suit ours.

Other chemistry bad
