Is it staying dry now, or will you have to wait for middle of winter again to assess?

I'm not arguing with you, Dr. Bob - My post was an enquiry. If your recommendation is 14V based on addition of cell values rather than multiplication of cell values, I understand your concerns. What I didn't state, and perhaps I should have, is that my BMS controls both individual cell voltages and pack voltages - any anomaly in either results in protection. So, I have my cells set at 3.75V and my 8S pack at 30V - either limits a dangerous situation. And as Nick has pointed out my chemistry includes yttrium, so my limits may not apply to other LifePO batteries.

I think you are further confusing the issue. My term "Recommended maximum voltage" and your term "maximum recommended voltage" are not the same terms. You are misquoting me, as well.

I can't understand pigheadedness - the term "maximum" is what is you're missing MtB. None of your replies include that. You choose to ignore it.

Please do not ascribe bullshit to my name. Read my post carefully. Then, if you wish to quote what I said; you can cut and paste exactly what I said.

I don't know where 14V comes into a "dangerous" zone in the case of my Winston cells - The supplier recommends a maximum charge of 4V per cell which is 16V if I understand maths correctly? https://files.gwl.eu/inc/_doc/attach/StoItem/3861/ThunderSky-Winston-LIFEPO4-100Ah-WIDE-Datasheet.pdf

I took a simpler route for my LiPo4 bank. I don't charge them via alternator. Solar only. And a genny for winter necessity.

That would certainly end my boating days...or all my days.

You might be thinking of Nitrogen?

You'd only need to rest them on a couple of match sticks to allow the cold air out?

I recently discovered some mould in the back of a cupboard - it's against the lining of the cabin about a couple of inches above the floor - behind the lining is a gap between the edge of the floor and the spray-foam insulation. I think the cold air in the bilge is causing condensation to form in this area, leading to the mould. So, I have some questions...is this gap to allow ventilation to the bilge - what would happen if I closed this gap with more spray foam? - just the area behind the lining of the cupboard - bear in mind the other side of the barge would still have the opening. Would it be better to have vents in the cupboard panels to draft more air through this area? Or both? It's easy to remove and attach the cupboard and lining for access. The other thought I had was in how the bilges are constructed - reinforcing cross-members span the bottom plate - channels are cut to allow water flow to the rear of the vessel - for water...but the top of the cross member is used as a platform to support a batten that supports the floor - the battens, as far as I can ascertain are not notched to allow air to circulated - so each reinforced "cell" between the supports does not have good air-flow barring the side sections, which as I have mentioned allow the cold air to cause mould on the cabin lining inside the cupboard... What about sealing the entire interior floor section - airtight, then dropping in Argon gas to prevent mould and as an anti-rust? I imagine it would be simple enough to fit a membrane under the floor, with a gas valve to introduce the Argon? Because Argon is heavier than air, it should stay there and topping up would be a simple affair, when needed? Any thoughts?

I recently had my Chinese diesel air heater also run badly - unlike yours, mine was white smoke and not starting at all. I disassembled the burn chamber and found it to be clogged with carbon. After a good scrape out, it is back to normal - I have adjusted the pump and fan speeds to try to lean out the burn to prevent this from happening again - this was after a year of running. You may have a fuelling issue too, but you may have caught it earlier than I did. I suspect mine would have gone through a smoking phase before it failed on ignition.

The argument here isn't really how coal was formed, rather it is whether coal is still forming. As the Wiki page tells us - 90% of the coal formed in a specific prehistoric period when certain conditions were favourable. Those conditions since that period have been sporadic and intermittent since, the coal seams found around the world point to this.
