    The price is around $500 without freight & only weighs 12Kg , my Fullriver weighs 36Kg & i have 3 of them.

    I will update as we progress.

    Sue nice article on your beast, looking forward to seeing it all setup!

    I don't suppose you have a link for this battery by any chance?.. I am presuming you already know it fits under the seat? Or are you looking at installing it elsewhere?..

    Now i know that you can fit 2 N70 in the battery area under the driver seat i will be getting a couple for my needs, one in the truck with 3 in the camper or more if i can fit them.

    We deal with a number of electrical factories in China, had no need for their batteries.
    As weight is starting to be a problem & room, i thought i was time too look at the options & Lithium looks the goods.

    Time to get some & test.

    The size of these batteries are smaller than the Fullriver 120ah. We are looking at 50ah, 100ah & 160ah, even the 160 is smaller & only weighs 15Kg.
    This may help some, but its just what i'm looking for for my problems.

    Cheers

    hey guys.....if you move the electrickery from under the drivers seat to up higher.....under the centre console......

    you can also use the drivers side seat box for more space......

    someone on here sells a special box designed for this......and the console just bolts on top.....it raises it up a couple of inches and makes it more comfortable as an arm rest......
    and you can drive through deeper water without the fear of drowning the ecu....

    Hi Witchdoctor and be very careful with adding a lithium battery to your set up.

    The brand and company you are looking at have a good name in the lithium field but a fully charged lead acid battery has a fully charged voltage of 12.7v, but a lithium battery has a fully charged voltage level of 13.2v.

    These two different voltage levels can pose problems, particularly as most standard type isolators are set to cut out when the voltage drops to somewhere around 12.7-12.9v, and lithiums sit at a constant 13.2 until they are nearly flat.

    Thanks drivesafe, these lithium batteries come with a built in BMS to maximise the batteries performance.
    So an isolator will not be required, very impressive.

    Hi guys,

    The only thing I know about electricity is if I stick my finger in it I'm cooked.

    But I bought some time ack a mini booster, the guy told me it could run a fridge for 2-3 days.. It's small compact, you don't need any solenoid thingies and that other thingy, you just plug into cigaret lighter to charge..

    I figured you could have two of these for the price of a dual battery set up, but I could be wrong because I know ack about hs subject..

    So here is a link, note- my one I bought is slightly bigger than this model but not by much. Can a tech head have a look at this and give us the Pro's & Con's on this as apposed to a dual battery set up. Cheers.

    Our fridge is 40 litres and uses about 4 amps per hour.. that Mini booster thingy is only 14 amp hr.. now where near enough power to run anything like a fridge for more than a couple of hours..

    Most batteries.. especially lead acid batteries may be 14 ah but you will only get 7-8 ah out of it before the voltage drops too low.. you will never get 100% capacity out of a lead acid battery.. and if you did that would be then end of the battery..
