They do not communicate with the charging system, they are standalone and just isolate the battery from the system. The 12V group advocates these for the hybrid setup with a lead acid left in parallel so the alternator or other charger does not suddenly loose its power sink and give a voltage spike.

If Stenson lock is closed is there a shortage of water travelling downstream. I have no idea if there are any other feeds between Stenson and Shardlow.

We spent a few days there in June, moored in the Oozells Street loop VM, no shortage of space in the area.

Is the boat a residential boat, i.e. a liveaboard. If it is then the gas work should be done by a gas safe fitter with LPG and boat acreditation. I have no idea if this would cover running a pipe but not making any joints or connection of appliances.

The gearbox dipstick is integral with the filler plug, the brass nut seen in the lower left corner of the gearbox in the photo above. When you remove the plug there should be a 150mm long steel rod about 4mm diameter attached to the nut with marks on the lower end for the oil range.

How about when the whole boat lifts up as it goes over the obligatory washing machine on the Rochdale creating a significant point load.

Carling Galore !!!

Time to get your multimeter out and check if there is power at the fridge to eliminate that as a problem.

We have one of these in the galley mushroom vent and one in the shower room. 12V light and fan

Timing lately has been critical, we sold our old boat early 2020 and then cursed because later that year prices increased. We signed the contract for our new build in early 2020 and cursed when lockdowns put delivery back from Oct 2020 to April 2021. We thanked our luck with the timing when new boat prices escalated significantly through 2020 and 202, we were probably one of the last boats through the builder before escalation or availability problems.

12ft widebeam, isn't that going to make it a wide load so transport firm will need to do more planning and notification of the authorities. For questions of mooring in London, join the London Boaters Facebook group, they probably have more up to date / local info.

The price rises over the past year or two have a lot to do with it. 2020 would give you a boat with a much higher spec for £170,000, with top quality crafted joinery and fit out. Those £170,000 boats are now £205,000 due to raw material increases. 3 years ago it would have been a £135,000 boat.

Enlarging the photo it does not look like solid bus bars along the whole length but a series of short interlinks between each adjacent battery, so a double interlink connection at most battery terminals in the daisy chain.

For the avoidance of doubt I meant The measured total voltage is not necessarily the mathematical sum of the 4 measured voltages because the BMS may use a different sensor for the total voltage and not just add up the 4 individual voltages. I thought this would be understood from the context.

The individual cell voltages and total cell voltage may be being measured by different sensors which have their own inaccuracies and may therefore read slightly different. The total voltage is not necessarily the mathematical sum of the 4 cell voltages.

As you are in Burton on Trent have a look at Aqua Narrowboats, they are based in Foston on the A50 so not far away. Good record of fitting out boats over a number of years.

Perhaps they have closed on line purchasing for Christmas Hols, banner at the top says open on the 4th.

someone filled the pantry at that end with too much Christmas food.

3 or so years ago. Restrictions are slightly less onerous if you are a member of the British Model Flying Association.

The same rules applying to drones now apply to radio control planes and helicopters. I fly RC planes and have operator ID from the CAA (civil aviation authority). All things like drones and RC models are classed as Unmanned Aircraft Systems (UAS) in the Air Navigation Order, the law covering all flying.

Here are some possible settings to start with, but really, the BMV needs to be tuned to your system and batteries to work correctly, there are several videos on Youtube from Victron describing this. Battery Capacity - 440 Ah (but as Tony above says, they may no longer have this actual capacity) Charged voltage - this should ideally be about 0.2V below your absorption voltage so if you normally charge at 14.4V then set this to 14.2V. Tail current - 1.5% - this means that when the charge current is less than 1.5% x 440 = 6.6Amps and the voltage is above 14.2V then it will go to 100% Charged detection time - leave at default 3 minutes Peukert exponent - leave it at the default 1.25 Charge efficiency Factor - 90% Current Threshold - leave at default 0.1A Discharge floor - 50% Leave everything else at default. The key things to getting them to show a bit more sense are the Charged voltage, the tail current and the charge efficiency factor. However, once again, I echo Tony's comments above, if the BMV is not tuned to your batteries then it can lie to you, so watching the voltages and currents is a good indication and the BMV gives you this data. I trust my BMV but I started with new batteries and spent time watching how the batteries charged to tweak the parameters.

Blackrose, That is good info for the future, guess I am lucky that when I did use it over a large surface the cork tiles were flexible enough.

I only had about 5mm space under my bare steel hatch so i glued some 3mm thick cork tile on with a no more nails type glue. You have to do it the hatch is dry and warmer and try to press something against the tiles to avoid an air pocket while it sets, something like an upside down broom wedged on the rear steps. Worked for me. Do not use the self adhesive tiles, the glue releases when the hatch gets very hot in the sun.

Remove it from the negative post and see if this makes a difference. It works by creating a small voltage for the controller to read and if the case is not isolated you may have created a ground loop affecting the voltage, hence affecting the measured temperature. My Victron one is bolted to the negative terminal but the case on that is definitely isolated.

My Tracer was once a month but that may have been a nominal month, i.e. 28 or 30 days. However, I had it set to 0 min duration.
