  4. Then there are loads more that are wrong here is another and the test I did on a car today is wrong Automotive Charging Systems - A Short Course on How They ... https://www.carparts.com › classroom › charging

  8. Really? I advance you this, I did try it today on a car ad it did regulate the voltage, turn lights and fan on and it upped output How Does an Automotive Voltage Regulator Work? | It Still Runs https://itstillruns.com › Electrical

  13. They should otherwise the batteries will end up cooked!! or is that boiled? thats what the regulator pack is for to regulate

  15. Maes which is a local vehicle electricians big concern, one of the mobile guys is a friend of mine so he did it for us, but most alternators drop to float after bulk charging older ones anyway, modern ones are controlled by the ECU
  16. Why not have your alternator regulator built to the correct voltage? John who bought 4 of my batteries has one thaat goes to 13.8 then drops to 13.2 volts which is ideal
  17. I had the magic smoke when the mosfets failed on my curtis speed controller, easily and cheaply replaced though, and the use of them is why we have PWM speed control rather than resistive speed control which wastes loads of energy
  18. Mine is stuck to the steelwork and to the woodpanels so its double thickness,, the owner went over the top on this boat I think
  19. Kingspan or its equivalent is better than the rockwool, seen to many soggy boats because of badly installed rockwool, whereas the foil gives a vapour protection as long as its sealed, I have sprayfoam and thinsulite on the back third of the boat, and double thinsulite on the front two thirds, the stern is warmer plus it gives better vapour protection to the steel. Rockwool is cheaper than kingspan, I have just paid 16 squids a sheet but it is the better product even on your fibreglass roof
  20. Thats the issue Mike, Valence say the board in the battery requires a BMS to control it Geeks from the USA say that if you connect the batteries together with the leads the batteries do talk to each other, all I know is that the board is live but changes when the puter is connected, however even when reaching 100% and the puter not connected the cells are well balanced, which shows when the puter is plugged in and cells are green. what this has done is give me a false sense of security, backed up by my recent check of the van, which works very hard, both in acceleration and regen, maybe the constant solar keeps them balanced? maybe its luck? or maybe valence are telling porkies and the board is a BMS which balances cells. But as I dont really know maybe I should check more often? but its a faff so I dont bother unless I am doing stuff on the batteries By the way that listing is for LA batteries
  21. I do know, they are all balanced and I know that because when I last checked them with the puter months years ago they were fine...........................I have however checked them on my truck and that works harder than my boat batteries and they are all linked, all balanced and cells balanced as well. so i will check them next year just to make sure they are ok? Seriously Mike these batteries are top spec which is why they are expensive secondhand
  22. I go out to watch a film and have a few bevies and this whole thread gets ever more complex!! However I am sure between you a cheap drop in system will be deigned and for sale shortly, just dont try to sell me one my system works just fine for me
