Like I said, I just find it hilarious that a self proclaimed clever bloke is so naive and gullible. NABO πππ Like I said, not as naive and gullible as those who gave you money to join your ACC. More assumptions from you. Can't help yourself can you ππ€£ππ€£

After plodding through 6 pages, much of it bile, I've come to the following conclusions. 1.Β Β Β If you don't sit about for days on end, and have some solar, lead acid batteries will suit your boating style at a reasonable cost. 2.Β Β Β If you want trouble free Li on batteries that do what they are supposed to do, AND you can charge your starter battery without frying your alternator or remembering to switch it on, or relying on an indeterminate length of thin wire, then you pay someone a lot of money to specify and install expensive control equipment. (Assuming you don't know how to build it or do it yourself. 3.Β Β Β if you rely on facebook et al to 'design' an alternative that combines both chemistries, you stand the chance of ruining your expensive batteries very quickly, just like lead acid. 4.Β Β Β Why has no-one mentioned unputoutable fires? Unputoutable fires are a problem because they can not be put out.

Unputoutable fires are a problem because they can not be put out. Yes I seem to remember you had a problem like that? Yes I had a thermal runaway with a small lithium ion jump starter. Quite bad but I got it out of the engine room and hung over the side before it went up in a large fireball. The vapour/smoke coming out looked wrong so needed moving. Runaway is a good word for it. I probably dodged a bullet there, as usual. Small engine room dirty oily clothes lithium battery fire not a great combination.

Yes lithium ions are a danger. I donβt think this has happened on a lithium iron though?

Why has no-one mentioned unputoutable fires? 1/ I think itβs one of those things like an iPad or an air fryer - you canβt see the point of it unless you actually try it. For us it means we have switched mostly to electric cooking with 2 minute heating uo time for the βovenβ, I cam run the immersion heater from the batteries if we need more hot water, etc. Of course if you find virtue in living it rough without the comforts of home, as plenty do, then you may not need it. 2/ Iβm not sure you need to spend a huge amount of money. Get bare cells, an off the shelf BMS for Β£150 or so, and it can talk to your solar charger. If you are prepared to wheel out Β£500 or so for an alternator controller then you will have the full all singing and dancing system, probably for close to or less than the cost of buying βdrop inβ with built in dumb BMS. 3/ Almost certainly correct. 4/ There are no unputoutsble fires with LiFePO4. Only with lithium cobalt or lithium titanate. These latter produce their own oxygen so will burn underwater. Not so with LiFePO4, and that doesnβt spontaneously combust. Just been looking at LiFePO4 cells from a 12v system that were connected to a failed solar controller, panels were directly connected to the battery and put in about 100v. Cells swelled up, vents opened, contents ejected but no fire. As I understand it it is virtually impossible to make an LiFePO4 go on fire unless you hold a blowtorch to it. All these fires you see on the news are not LiFePO4.

I've never overcharged a LFP.
The problem was I used non original leads. The pack had an SB50 socket so I just made leads with crocodile clips. Original leads had diode pack to prevent back charging.
Result was engine started and alternator voltage exceeded the pack top voltage (3s NMC battery) and went past the danger zone causing the runaway.
Up it went.

There are no unputoutsble fires with LiFePO4. Only with lithium cobalt or lithium titanate. . LTO are safer than LFP batteries. You can get a LFP to thermal runaway by overcharging it.

Be a bit careful nick, don't take it too far. How far did you take it? Well not as far as you did with your underage grooming of boys innit. Tell me why you have not been prosecuted for your historical crimes? It was a crime after all. I'm pretty certain you could still be prosecuted if a complaint was made to police Scotland, which in my personal opinion should be done. No criminal should escape justice, even if it was years ago.

You could be right about LTO. But as far as Iβm aware there havenβt been any instances of LFP going on fire, they just vent out the electrolyte if severely overcharged.
