Portable power

Every installation i've done, the smaller size of the cell pack is a benefit.
That’s what I was saying, sometimes it makes sense, usually not.
Warranty is a thing too though and adds value. What warranty do you offer on your batteries? I’m not trying to catch you out or argue, but you’ve ignored this several times now and it would be useful information for this apples to apples discussion.

Bearing in mind OP wasn’t even asking about batteries but full power solutions with charging and inverter built in, it’s a huge leap to building the battery
 
And how does your insurance company know the quality of your construction? Most people are not qualified professional electricians with professional insurance, so self build just isn't feasible whether financially viable or not. Fogstar ticks the box for insurance, as do portable power banks, but components sourced from AliExpress and self assembled rarely would.
More thread drift but so far I have installed around 200 of these packs or batteries for customers and not one has had insurance questions let alone problems. I have literally only seen people say they were asked on this forum (despite having had full quotes after providing full details of my own install from at least 6 major insurance companies ; not one of whom asked about LFP) and the only question seems to be was it professionally installed . As there is no legal professional standard in the UK I would guess anyone who met the ISO minimum requirements could answer yes.

I don't think Paul or I are touting for business by promoting cells over drop ins - people can choose a drop in or to self build or have people like us build them but there is demonstrably a cost saving (large or small) - which may or may not matter depending on budgets and attitudes but as I said before its about quality for me. I put my professional indemnity on the line installing anything and having seen the quality of many types of drop in, even from very well know makers , I choose not to use them in most cases.

As I noted above, Battleborn are a prime example and the villain du jour , but have a (possibly worthless) 10 year warranty and would tick the insurance box... but now I have seen the way they are made I would not have one anywhere near me or my customers. Same goes with many others. Each to their own I guess

I guess lithium really is the new anchor when it comes to topics

It was you that drifted the thread onto insurance issues and i responded to that. You wriggled and twisted to try and justify your incorrect comments regarding savings, insurance problems and now warranties.

Have you notified your insurance company about your DIY Lithium installation ?
 
A couple of points.
I'm probably a bit out of date with my info, being something of an early adopter. When I built my first battery five years ago, 'drop in' units were far outside my budget, and nobody in the UK was selling the components. So direct from China was the only sensible option, and it worked brilliantly.
It's entirely possible that these days it doesn't make as much sense, both because of a general fall one prices, and better availability locally.

Second point, on insurance: with the combination of sailing area, boat value, and boat age, I was stuck with Pants. They wanted to know what make and model of battery I had fitted. I really didn't think my DIY system would pass muster. I ended up going third party and the requirement was dropped.

So it’s a no on the warranty then?

I have not wriggled and twisted at all. Insurance always prefers professionally built and supplied products to homemade things as there is someone to sue if it goes wrong. Your speculation that they don’t care is just that.

Of course it is and you knew full well that i'm not going to be buying a product with a 1 year warranty and passing it along to customers with a 10 year warranty, especially as i supply the cells at cost, Fogstar do not give any trade discount on their cells.

You started off by saying "Most people are not qualified professional electricians with professional insurance, so self build just isn't feasible whether financially viable or not. Fogstar ticks the box for insurance,"

That's what i responded to in post #49 and expanded on in post #56

I am not promoting custom cell packs as the only way to go, but the arguments you put forward regarding insurance are incorrect. As i keep saying, the battery is but one component, if you use a Fogstar battery as part of your self install it makes zero difference to the insurance company. If they want a pro install your Fogstar battery doesn't make that true, it's still a self install, you specified and fitted the cables, the fuse, the isolator and the other necessary components.

You keep skipping the question "have you notified your insurance company of your DIY LFP installation ?" If not, there are some companies where your insurance is void.

I can see the Insurance angle getting worse in the future for non pro-install lithium.

We all know exactly how hard Insurers can wriggle with a payout looming......................................

Until we have a firm specification with strict easily adhered to guidelines accepted by insurers for litium install, I'm sticking to my LA bank supported by my Bluetti.

Which for me, as a leisure boater, not a liveaboard, works fine.
