Since nobody else asked, I will: What's the electrical item, and why does it need to be on in a barn?

LOL, Always good reading what has gone on with peoples comments.

The pump is no worry in the barn, and the tracker will last a long time on the battery - but I dont like the idea of going out knowing its not full.

and the idea of the spare battery is a good idea, and one I would do, but its a total pain to remove the battery - a two person job with plenty of sweat.

I have one of these: Clarke Heavy Duty Jump Start 4000 - Machine Mart which is one of the best value jump starter packs you can get.

And for no other reason than it is the latest model have just bought one of these: Clarke Dual Voltage Jump Start 12/24V - Machine Mart

With all my gadgets and gizmos I never know when I will need instant power, but once the fuel cells are fitted I will be fine

So if anyone fancies a deal on the now spare 4000 let me know (will start a 4ltr diesel)

On a side note,

A woman came up to me in the marina car park the other day and said "can you help me" I thought oh dear! what grief now, but anyway replied "what's the problem", she said "my grandfather changed a bulb for me in the car and has left the lights on, now my battery is flat and I need to get home, have you got anything that can help" I just could not stop smiling to myself because in my truck which I was standing next to was 3 x batteries fully charged, the two battery jump packs above and two sets of jump leads

God MUST have been looking down on her and sent her to me, peteR75 from this forum was standing next to me at the time, we just looked at each other and smiled, we were thinking the same thing. We told her that she had hit on the right guys and we could most certainly sort her out, anyway Pete went off with her and gave her a jump, so she was very happy bunny

I certainly know a lot, I haven't gone through life to retirement with my eyes closed but as for knowing everything, certainly not, unlike some I know, when I don't know something I am happy to ask, I don't just pretend I do, or make up some bull answer and post it with authority to make me look good, only to later get sussed out by those that actually do know

You get to an age in life where you actually don't need to impress people, you do things because you can or you want to, not just to keep up with the Jones's or because it is a fashion fad. You can also read people a lot quicker and easily see the bull sh..ers, or those that seem to have got through life having everything done for them so are clueless, it's quite funny really

Does that answer your query

Oi, keep on track, your getting me in trouble sort this leccie problem out for the chap or he will blow a fuse

Struggling manfully back to the topic - re charging from the car. A caravan socket (either a13 pin or a second 7 pin (7S) socket) gives a choice of a permanent or an ignition-switched 12V supply, designed for charging caravan batteries. So fitting one of these and as someone says above running the lead to a high current (DIN) socket on the boatto supply the battery(ies) is a neat way of doing it. I tend to think of it like recharging a flat car battery after a jump start - running the car for half an hour or more seems to do the trick

Check out carefully what type of wiring your car needs, modern electrics don't like extra wires just spliced into the loom, fouls up bulb failure sensors ans potentially much more complex stuff that runs trailer sensing, multiple bulb operation,etc.

You really want a bypass relay anyway in the wire to the boat so the connection only completes if the car is providing power -otherwise you risk the car trying to draw current from the boat

A simple solution may be to buy a another battery keep it charged at home and swap it for the discharged battery when you visit the boat or want to use it, then you can recharge that battery at home.

has already been suggested! but the battery is in an awkward place to change over

[Leapy]

Can't help but think something's got to give here...barn with no power, boat with things drawing current all the time, no sunlight for solar power, no provision to charge whilst towing, not always time to charge when moved to launch...

Personally, assuming the barn's a given, I'd be looking to make the batteries easily removable and take home one at a time to charge with a smart charger. Then, switching all off on the boat except the tracker.

Solar panels - too expensive, too big for a useful output, unreliable weather. Wind turbine Charging whilst towing - depends how far you tow, batteries still in an unknown state when you get there.

Better to start your journey with good, known batteries than arrive somewhere and find them flat
