Yes I know that. I am referring to the fact they are visible not that someone can alter the settings. If you had a grands worth of Victron gear with bluetooth someone standing outside the Boat could see what was in there just by having the app. It must work like that otherwise if you got a new phone you could never use it if the devices were not visible. Given the value of some of the gear people put in Boats it would be worth doing something about this as it seems to me to be a dodgy security flaw.

Thats an idea. This is getting into a 'How d'you like my BMS, don't you think its sexy, come on sugar let me know' type of discussion. Lead is an idea but also defeats the usefulness of being able to check the battery status when on the lavatory.

Its interesting. With the Victron MPPT one can turn off the bluetooth with the phone but for obvious reasons it has to be switched back on using a computer and a wired connection. It is a basic flaw of a very convenient product but if one can just unplug the BT module that is great. I did wonder about metal box but I am sitting beside my nuclear bunker in another Boat and my app can see the Victron even though there is 5mm steel between me and the unit.

They will be password protected but they must be visible to the phone app otherwise how would one connect to the device? That is the security flaw. Being visible and identifiable to anyone with a mobile phone running the app. I am guessing the app is freely available.

You mean it is not visible to someone who has the app on their phone? That would be good.

I don't want bluetooth batteries in my electric launch. I could go off shopping and some non specific could stand beside the Boat put their bluetooth on and find out what is in there. Expensive batteries are worth nicking. Maybe the ne'er do well non specifics didn't think of this. What does the battery show up as? My Victron controllers are visible from outside and despite putting individual names on it still says what the hardware is. Security flaw.

The Eco also has no heating pad in it. Interesting about the cell grade. I thought they said grade A but you are right there is no reference to the grade. Intriguing. Also the warranty for the eco is 6 rather than 10 years. Cycle life is interesting. I am not sure but I seem to think assembled LFP batteries which are being marketed as suitable for charging at 14.4v by alternators may have a shorter life than plain LFP batteries which are charged at say 13.6v by controllers where you can set the voltage. The 14.4 is advice but may be a bit high and thus the expected life is reduced on an assembled battery marketed as a lead acid replacement.

Maybe he meant a spin.

Not sure but the Drift 'eco' has REPT cells whereas the others have EVE cells. Presumably the EVE cells are more expensive. Maybe BMS difference also? I have been thinking of getting 4 of the 'Eco' 100Ah batteries for one of my electric launches. Price looks nice. £200 each ! They must be inferior to the standard product. The 'Pro' range have com ports (RS485).

Another approach is to write down voltage v soc levels from research papers. I have LTO batteries. Approximately 400Ah at 15v. This website is good for SOC OCV graphs. Of course in my case there is no draw overnight as I have no mod cons on this Boat. So these figures are probably reasonably accurate as they are open circuit voltage. For LTO @15v the figure is multiplied by 6. https://www.researchgate.net/figure/The-OCV-SOC-characteristic-of-the-LTO-based-battery-measured-at-different-temperatures_fig4_324117029 for LFP batteries the curve is much flatter between the 'knees' so more difficult. As Nick said about just keep it over 13v all the time and life will be Good.. https://www.researchgate.net/figure/SOC-versus-OCV-Curve-for-an-18650-Lithium-Iron-Phosphate-LFP-Battery-Cell_fig1_304655337

The back deck cants seem to wide to me.

My mother used to call such areas 'dogshit alley'. Its remarkable how concentrated it can be. Obviously horses have a tendency to use the same place. I guess naturally dogs do similar without training so a hotspot could be caused by a small number of animals doing the same thing every day.

It seems odd that dogs are not trained in strategic defecation location techniques. One of our lurchers was brilliant about this. She would disappear to an area where nobody normal would ever go then return having offloaded the extra weight. It was amazing. In a hedge, in a McDonalds, scrap car or whatever. I think in reality dogs could be trained for this. It could be a whole new industry. Doggie poos training. Fed up with taking bags and that warm feeling? Bring your faithfull mutt to doggie poos strategic defecation training and we'll have them crapping wherever you like. Special offer 6 sessions for the price of 8.

Definitely. However having done some research it appears these bolts usually go into the drum. I think @blackrose might have had the same unit as I did. It was a Zanussi 3kg compact 1300rpm spin. The machine did operate in that the drum was not locked but the bolts were holding the concrete counterbalance weight. Thats why it was walking all over the place. And I thought it was the Woman overloading it !

I guess the non-specifics are doing well out of fly tipping.

I had a similar problem with a Zanussi compact machine. It turned out that there are transport bolts fitted which prevent the machine being damaged during transit. I had not read the manual and thus did not know about them. I ratchet strapped it down to stop it moving about then someone told me about the bolts and it was much calmer after I removed them. Something to do with the balance weight.

I had an indesit tumble drier when I was living on the barge with the Woman and the offspring for several years on a mooring. It was alright but I did have a rule about only operating it when someone was on the Boat. I am pretty sure the fire risk is associated with people failing to clean the filter screen. RTFM. It gets blocked with light material which causes two negative outcomes. One is that the hot air can not get out of the unit so easily and the second is that there is a load of hot dry combustible material available. So yeah. Clean the filter screen regularly and be on the Boat when its running and problems go away. Tumble driers are marvellous contraptions IF you have the power. These days I am off grid with no generator so nowhere near enough power for all this sort of thing but with adequate provision I would certainly have one.

That is also possible. I wonder if humans ought to consider similar used food displays. With modern LED lighting one could make it very beautiful of an evening.

That might well be why they have been removed.

I am navigating the upstream leat for Clewer mill right now as it happens, in one of my launches. It is ironic given the amount of water running down the River that only a tiny sweetening flow is going down here. Its like mid summer. Putting hydroelectric in mills seems sensible. having said that the chanel is very badly maintained once past the Windsor acecourse marina.. Nice day for a short Boat trip.

It would be worth checking the inverter as suggested. Its not implausible that the washing machine was only used when connected to mains elastic trickery. Inverters and washing machines are uncomfortable bedfellows. I can be similar to having a hoarde of small lobsters in your bed. Definitely worth checking. Water use is relevant.
