    I was googling last night at work when I had a spare few mins exactly the same thing

    my concern is stuffing it up and having a spectacular flash of white happen in my hand s
    with these you get good quality cells and a battery management system that allows 100-150 amp discharge so when you have a few batteries you can run hefty inverters to run microwaves toasters kettles etc

    You have to compare these to quality batteries around the $1500 range not the junk you see for $442 on special that only manage 50 amp discharges and 1/3 the cycle life

    the better batteries also handle higher input charges 40 amps or more for quick recharges

    Those 6 cylinder batteries would be 270 amp at 13.2volts at 493US.

    Those cylinder batteries are lithium titanate oxide and there cycle life it way better than the lifepo4, this guy stuck a nail into a small lifepo4 and wow it exploded, the guy that did the 280amp pack dose a test and hes very interesting and tests everthing with a bms.

    thats the internals of one of those sub $500 100a/h lifepo4 batteries

    Chris take note of that video "A Grade Cells" Chinese are known for recycling cells re wrapping old cells and classing them as new A grade also selling lower grade cells as high quality A grade they do it with all there lithium batteries, do agoogleon some of the stories before u buy

    Theres a reason aussie lithium titinate sellers charge $80-$120 a cell

    Aussie seller here they cant sell u gabage because they'll be sued easy https://www.capitel.com.au/products/...tanate-battery

    Buy from china its a big gamble read the reviews on ali express or dh gate
