    12v power pack - 'Poopy Power!'

    Having purchased a tent for the first time for years, when I do go away in it, I intend not to use hook up, just have a simple grass pitch.

    However I don't want to go down the road of gas lamps or tilley lamps or even battery lamps, so I have purchased a small low wattage 12v awning light. Also I'll need to charge my phone and my iPadmini and it is generally handy to have a bit of power. Yes, I could charge everything from the car, but that would need the ignition on and the car unlocked.

    Anyway, I have 2 spare 85ah leisure batteries, both of which came with seperate Romahomes. I have a 110amp leisure battery which I have put in Hettie, so these two batteries are fairly redundant and have been cluttering up my kitchen for a while. I've kept them charged with the Ctek charger so I know that they are in good condition. Anyway, to cut a long story short, I have made a 12v power pack.

    I have an 85 ah leisure battery in a wooden box, powering 3 x 12v accessory sockets. They are on a switched 15 amp circuit and each socket is individually fused at 10amp. I have a 150 watt simple inverter as well, so I'l be able to run or charge most simple low wattage devices if necessary. The USB plug-in 2 x 2.4 amp charger also doubles up as a voltmeter to monitor the condition of the battery. The pack switches on with the green illuminted switch. There are 2 vent holes at the back to allow the battery to vent

    Also, I will be buying a Lidl/Aldi battery charger so that if necessary, I can at least partially recharge the leisure battery through the 12v system on the car, using the inverter with the battery charger plugged in.

    The box will double up as a work surface, seat, footstool etc. The main part of the box has the battery and wiring in and there is a small box section as seen in the last picture where the inverter, battery charger, spare fuses, Usb charger and odds and ends can be stored.

    Almost finished, I just need to attach two old webbing belts as carrying handles, when the paint fully dries and proper quick release battery terminals coming tomorrow.

    Due to the somewhat dubious colour, it has been christened 'Poopy power'......

        Looks great Panda, just the job.

        More or less the same as the unit I built for camping a few years ago.

        I cheated slightly though and used one of these as an "all in one" battery indicator, sockets, surge protector and fuse. https://www.amazon.co.uk/dp/B076Q2S7..._qVTaFbZ6YDV77

          Good project and looks really good. Plenty of power available for the camping trip.

          I built this a year or so ago to power my radio when out in the field and although only 14amp, it powers my radio, charges my phone and has built in LED lights. It is topped up during the day by a folding 45w solar panel. https://www.youtube.com/watch?v=Ofx1OfAz9c0&t=3s

            That's really nice. Like the use of the ammo box.

            I did look at using a big leisure battery box myself, but as I had a load of old tongue and groove in the cellar, hey, I used that!

                Quick release battery terminals all fitted. Just got to sort the handles tonight.

                  This is mine. There's just enough space in the battery box (a marine boat item) to hide the connections and cabling and the Bestek unit sits very neatly on a little recess on the lid.

                      All very ingenious, and neat.

                      I used to hoik the battery out of my caravan when going away in my Combi Camp trailer tents and bung it in a plastic crate, used it to power lights, charge phones etc using crocodile clips.
