    We're planning to go to disney this christmas where we will surely freeze!:Wink:

    Anyway, we have one 85ah battery at the moment. We will be using some lighting in the evening, say 2hrs a day and obviously have the water pump. Heating is not blown so no power drain, just the gas for that.
    We have original lights, so tubes in the ceiling and I think halogen in the cabinet fittings...(does this sound right?:Blush:)
    How much power would these use, say every hour, and which are best to use (lowest power drain?).

    Also we may want to put on a DVD to entertain our son (keep him out the way!) when were sorting things like dinner. We have a portable DVD player which we usually run from a small cigarette lighter inverter when we're driving for him or to charge the battery.

    Now, does the battery charge when the engine is on and idling, and would this be ok to run/charge the portable DVD also without killing the engine battery?
    Or should we get a cheap GENERATOR (got to the topic eventually)?


    Thanks

    3 days. Is my guess how long you last on a fully charged 85Ah battery.
    "Tube" lights are nearly as good as LED.
    DVD probably takes very little. We use our DVD/TV in that 3 day estimate.
    Generator is good insurance. We paid £200 for a new cheap sine wave 800W Chinese one from Trent. So far we've hardly used it but it was fine when we did.

    i think you may be under estimating your lighting usage......its dark by 4pm at christmas so, unless you plan on going out every evening, you will use a lot more.

    an alternator starts to charge as soon as its turning but the output will be low depending on the charge state of your engine battery but it will put back what the invertor takes out.

    a genny is a good standby......i lost all leisure power going to spain when the charge relay failed to kick in and i was running a standalone coolbox from the leisure battery. luckily we still had 500 miles to go so it got recharged after fixing the relay.

    Our plan would be to get up and be in the park early, then go back to van around 2 to eat and have a snooze, or at least a bit of a lie down! Then go back out (dark now) and into park until late. back to van and bed for the boy shortly followed by us!
    On the hunt for a cheapo:Blush: gennie at the moment. Will ask opinion before I buy:Wink:

    fair enough.....sounds like the useage will be about right then. :thumb:

    tv and dvd will use maybe 5ah between them and a couple of lights, maybe 1 to 2ah plus water pump and heating/fridge electronics.

    probably 2 or 3 days easy.

    still worth carrying a genny though.

    I'm on the case of trying to find a cheap gennie at the moment, just to keep the batteries topped up.
    We've got no room for gas bottles any bigger than the 6kg onee, so will have a couple of these.

    Is this the 1st time you've been in winter? We have been at various times of year, including October, December and Feb, and it is very cold there. Much colder than you would think so yes definately need a warm hat (I have a rather embarrassing Disney one which only comes out at Disney!:Blush:)
    We take a supply of thermals too as these are great as a thin base layer (you will need them).

    We've not been for NYE before. Josh will dress up, probably as a pirate. We don't have any adult costumes:cry:
    I won't ask what your wife is dressing up as then!

    Dont know how cheap you want to go but I have 1 of these in my van and it runs my drill and 5" grinder no problem :thumb:

    G850 Petrol Generator 850W - Machine Mart

    Its small, light, cheap and does the job but it isnt the quietest thing around and being 2 stroke needs oil in the petrol to run. Having said that what do you want for £75?? Its cheaper than a decent battery!!!!! :BigGrin:

    How about hiring one for trip ?

    From around £40 per week... if you don't need, or don't think it was a good idea .. no big loss..

    If you do decide to buy I would avoid the cheapo 2 strokes.. they are noisy and smelly... certainly won't endear you to the neighbours.

    Take a small genny, no worries then. Don't worry too much about noise nuisance, every other van will have one running, and besides, really noisy mechanical road sweepers spend an hour cleaning the site every morning, they start regularly at 3am:Eeek: That said after a day chasing kids around the park, most sleep through it (though not me:cry:)

    Have fun:thumb:

    When we bought our motor in March this year one of the extras we had fitted was an EFOY fuel cell it was an expensive outlay, but has been worth its wait in gold.

    It runs off methanol and the only noise when in use is a very faint humming, monitors the battery voltage and trickle charges the battery when required. We use 5 litre fuel cartridges and we still have at least 2 litres left on the first cartridge. We had six days at a site in the New Forrest without electric hook, we have also had about eight weekends wild camping in various places and the fuel cell has taken everything in its stride. Our van has one 85 amp/hour battery to feed the water pump, blown air heating, TV/DVD as well as fluorescent, halogen and LED lighting.

    If you need more info go to efoy.com

    Have a great time Disney:thumb:

    We went last year - cold? there were brass monkeys queuing at the welders:Laughing:

    Actually, we're cheating this year by traveling in the MH but staying in a hotel for a few nights over Christmas :Cool:
