SKT10

300w 25Ah lithium ion portable power bank with 1 year warranty, max 277.5WH
The LifePO4 are significantly more expensive at the moment so bitten the bullet and grabbed this instead
Small, light, excellent value for the price, good reviews
Somewhat small for camping but can buy 2 instead and still good value
I'm buying it to run a cricket bowling machine at the nets for my kids
$299, 10% off with SKT10, was $19 for delivery to Perth metro but I collected in person so didn't have to pay delivery

  how's it compare to the Bluetti EB4 - https://www.ozbargain.com.au/node/719898

    Cant comment on the quality. But this has 25Ah battery vs the bluetti 12ah.

    Example - A camping fridge would use between 30-40ah a day.

      I guess the EB4 is a LiFePO4 as well

    The Bluetti is a LifePO4 battery, therefore less risk of fire and longer lasting (more cycles). If it was a similar price, I'd go Bluetti

    Marked down from $600!. Deary me!
    For most uses one would be farrrrrrrrr better off buying a lithium battery… say 12V 100Ah for say $300. Here's an ozbargain example: https://www.ozbargain.com.au/node/723192 I'm not saying that is a brilliant battery, but compared to this setup I reckon it is! 1.2KWh nominal storage capacity vs the deal here @ .277 KWh - nearly 6 times the capacity! This is consistent with the weight of the item - 100Ah of 12V lithium weighs around 12 Kg, this weighs a bit over 2 all up.
    Life- 500 cycles @ 80% discharge is so appallingly low that I'm thinking they have no idea what that means.
    If you want an inverter or usb power, buy separate components and hook them up… what is in this deal is of no significant value.
    After reading a comment below I rechecked the specs, and realised this thing doesn't even have a LiFEPO4 battery! (the ones that don't flame out like the lithium cobalt etc ones.
    As someone with various LIPO batteries (the burning ones for RC models), a 48V lithium battery bank, numerous inverters and quite a few years playing with solar type stuffs I don't recomment this deal. If I overlooked various factors which would rule it out for me, I'd still reject it on price value. Just sayin…..
    I have no association with this or any other supplier.
    **as a further negative bonus… I see there is a max of 15A current drain =180W power @ 12V, which I am assuming is the "native" voltage of the battery, but curiously it is rated for and paired with a 300W inverter! Given inverter losses, that suggests it can only deliver 15A if directly connecting a load to the 12V, but magically can deliver about 29A if directly connected to an inverter. This simply makes no sense.

      Where to research inverters and components to attach to these batts?

        rooster7777 on 07/09/2022 - 20:28

        youtube is one starting point… keeping in mind it's good to look a lot, because no single video is likely to be relevant/ accurate to what your needs are.
        What are your needs?
        USB power stuffs from 12v car cigarette lighters are fairly common… ebay?

          @rooster7777: Is it feasible to build a home battery of i sissy have solar

          Any recommended channels? Just watched an eski type build n pretty cool

            @impoze: home battery of "i sissy have solar?" non comprendo… need more input/clarification.
            When I first started playing with stuffs my original source material were colin rivers booklets… they cover different fields ranging from motorhomes to solar, but many of the components and concepts are similar though some contemporary accuracy will probably have faded.
            There are a lot of videos about inverters, with a lot of inaccuracies, so gather info with a bullshit filter. Pure sine wave inverters are appropriate for stuffs with significant electronics… "power" inverters (non sine wave) are more suited to powering a heater or lights or other dinosaur stuffs. Not saying they won't power more complex things, but they aren't kind to them.
            A suggestion is search for giandel inverters… I've bought and used quite a few different ones with fair success. (meaning a few failures, but at a fraction of the cost of "real" inverters)

              @rooster7777: Lol sorry, i meant i have solar installed for my house. It may be something to look at after doing a few smaller builds.

                @impoze: If you mean is it feasible to build a battery for a solar house…
                the "Justin Case Solar Power and Bush Camping Australia" youtube channel is worth you watching. Unlike many youtube channels on the subject, he doesn't seem to do content for commercial benefit and many of the videos are relevant to your question.
                Complexity/ regulation increases for a grid connected system.
                My house projects have all been standalone (not grid connected) additions to a grid connected house - ie power the fridge/tv/computer etc via extension cord completely separate from the grid.
                Caravan/ motorhome projects can be very worthwhile, as the alternatives tend to be expensive… Colin Rivers publications are good here.
                Mine is more a labour of love with some payback… on a solely financial side it's been a bit like running a steam engine… if you love it it may be worth it, but it will be more of a money pit than a money saver. An off grid house is a different economic proposition, as power is always a lot more expensive than connecting to the grid (with the exception of those situations with very large/ isolated bits of land where running power poles can cost many multiples of $10K)

  Wish they had a deal on this model ITECH300P as it has a pure sine wave inverter so your electronics are safe when you use the 240v power.

  what sort of cells they use that are only rated 500 cycles at 80% discharge? Some really cheap/reclaimed batteries?
  ah.. not lifepo4…
  and inverter is probably modified sine wave.
  If you have 36V Ryobi batteries for something, their new 36V inverter is much better - pure sine, use existing battery.
  Waiting for a similar Ego one (next year)

  I would not recommend anything i-Tech, this is a cheaper brand that has very limited failsafes. I had a customer bring almost burn down his car, he was lucky enough to remove it from his car and obviously being lithium, couldn't put it out.

  EDIT: to add to this we refuse to install anything itech now on.
