  1. For my sins, I've spent 20 years writing server code that is exposed to the jungle of the 21st century internet: https://thekelleys.org.uk/dnsmasq/doc.html Making stuff secure and at least vaguely DoS resistant is therefore fairly second-nature. It's interesting though that one day I couldn't connect: it turned out that something/someone had made multiple TCP connections and used up all the (deliberately limited) connection slots. A quick rewrite to close the oldest connection when the limit is reached, rather than refuse new ones, fixed that problem. MP.
  2. The generator has not been used since we left lockdown at the end of March (but we did buy some juice from a hookup at the Retford and Worksop boat club last week.) I've not quite got the "power from fresh air" module in the software debugged yet. MP.
  3. I have a Kipor IG1000 and the manual says not to use fuel containing _more_than_ 10% ethanol, so it looks like that's in the clear, for now. MP.
  4. The algorithm I use is only little more complex, and works well. Amount removed from a cell is proportional to the difference between its voltage at termination and the voltage of the _lowest_ cell voltage. (So, if the cells are 3.56, 3.55, 3.56, 3.60, then the balance amounts would be 1Ah, 0Ah, 1Ah, 5Ah, or some similar ratio.) MP.
  5. I'm seeing cell voltages at charge-termination in the range 3.50 to 3.58, depending on which cell and state of balance, and end current of 20-25A. That suits me fine; I agree that there's no point in pushing the last percent for the sake of it. That sounds very good. All that wasted engine run-time MP.
  6. All looks quite familiar. I assume that C3's voltage actually drops towards the end because the charge current is dropping off? It's interesting how the same differences between the cells become evident at the very top of the charge cycle. MP.
  7. We think we have problems..... MP.
  8. I don't think you'll get a large enough gap to allow drainage even when first done, and by the time dust and muck have accumulated in there, you'll find it's permanently wet against the paint. The best option is probably to go for a good seal around the edge and enough sealant inside that to firmly stick it down. MP.
  9. Having had the same problems with water pooling under flexible panels and wrecking the paint, I stuck mine down with Sikaflex, onto newly-done paint. A year on, and so far, so good. MP.

  13. In an idea world, all Elsan points would be of the outside variety. So much more pleasant than a smelly shed. MP.
  14. Installation and use may be it. Ours is for the tunnel light, so it has a plug in it all the time, rather than the cap. I suspect some of the water ingress is from behind the socket, which is in a condensation-prone area. Whenever we arrive at a tunnel after a reasonable time tunnel free, I have to test, and jalf the time end up disassembling and fiddling to get it to work. MP.
  15. Noooo. The worst connector design in history. The sockets don't have springs on the contacts and rely on the springiness of the brass, which isn't. The waterproofing is crap too, if used outside. MP. ETA. I use the "Hella" 12v connectors. Not perfect, but a lot better than cigarette lighter. Originally used in WW2 german military vehicles, I understand.
