Edit: Removed from heading, but read below to get it for effective $159.
Woolworths Marketplace has a really great deal on this battery. Good ratings. Has 5 year warranty. "On special" elsewhere for $649. Aldi had it for mid $400s a few months ago.

Everyday Rewards gives 5,000 bonus points (total 5,870, worth $29).

Already a great price, what makes this a steal is the TopCashback deal of 35% (ends midnight tonight). Cashback is calculated on GST inclusive price.
https://www.ozbargain.com.au/node/865702

That gives $101.15. My purchase tracked in 32 minutes.

$289 less $29 Everday Rewards value and $101 cash back makes the effective price just under $159. If not using TopCashback, there is a $10 coupon for first time Marketplace buyers. Don't use that coupon if using TopCashback because it will probably invalidate the deal.

Specs for the battery show maximum 100 Amp discharge rate (200 amps for seconds).

Another good deal on Marketplace is a budget Devanti 90cm induction cooktop for $445.95 (not the best price around). But with today's cashback deal it effectively becomes $290.

    can this used in an EV as the startup battery?

    • tunzafun001 on 10/09/2024 - 15:44

      You mean EV Aux battery…not sure.
      I have mine rigged to a 12v inverter, and sometimes pull 200 amps continuous (making a coffee). It wouldn't be able to do that.
      But if its just the stereo, internal lights, BMU etc .. should work.

      But I guess there is a reason why they put SLAs in there and not lithium ?

      • team teri on 10/09/2024 - 17:48

        Yep, penny pinching. SLAs are cheaper, or at least were until very recently.

        Neverthless I believe Tesla switched to Lithium a while ago, because swapping over SLAs that die during warranty is not cheap either. A dead 12V battery is probably the most common reason an EV needs roadside assistance.

        Only a matter of time before other makes follow.

    • AndyRoo on 10/09/2024 - 16:27

      Most likely not just due to size

    • team teri on 10/09/2024 - 17:33

      I ordered one and will let you know when it arrives. I don't see why not if the size fits.

      If not, I've got a good alternative use for it anyway.

    Err startup battery in an EV? What would it be starting?

    It is 12 volts and 100 amps discharge rate, designed for RV usage for fridges, lights, etc, not huge current draws. Not suitable for starting vehicle ICE engines.

    • team teri on 10/09/2024 - 17:37

      The main EV battery (high voltage) is usually disconnected for safety reasons when an EV is not 'running'.

      A 12V batter is used to start up the electronics and switch the contactor that brings the main battery online. Then a DC-DC converter is used to top up the 12V from the high voltage battery and to supply loads like lights, AC, radio.

      I reckon, unless the car is stupid enough to start up the AC before connecting the HV battery, the current draw from the 12V battery should never exceed 20 or 30A.

  • internet-stranger on 10/09/2024 - 15:38

    Are there any budget inverters that can by used with these for 240v?

    • HappyPants on 10/09/2024 - 15:43

      Check out Giandel inverters, fairly well reviewed for a cheapie I believe.

      • internet-stranger on 10/09/2024 - 15:46

        They look good.
        Any ideas of there is anything on the market to both charge and discharge from 240v, e.g. like a UPS

        • ozhunter68 on 10/09/2024 - 16:23

          And some on ebay even have 25% off if paying via afterpay. They are good units designed in AU.

        • bamzero on 10/09/2024 - 17:16

          I have the 600w giandel sine inverter and it's been good so far (obviously light duty stuff).

          I also have renogys 3000w sine inverter but haven't tested much yet. It has ups function (though switch over time quite slow, around 50ms from memory so maybe not suitable for computer gear) but no charging.

          They do have one with charging and ups function, was a bit pricey for what I wanted at the time, around $700 or $800 so no idea what it's like.

    • tunzafun001 on 10/09/2024 - 15:46

      At 100amps, you would probably want two to take it to 24v. Then you have 2400 watts to play with. 1200w is a little limiting. Ie.coffee/ kettles/ hair dryers are generally 1200 - 2400 watts.

      • internet-stranger on 10/09/2024 - 15:48
        +1

        Yea. Was dreaming of a few of these and making my server rack “green” charge from 240v when solar was in excess and then running off battery overnight.

        • tunzafun001 on 10/09/2024 - 15:53
          +2

          Should work. Just don't burn your house down to save $5…

          I got my inverter from Kogan (used the credit card sign up credit). Way exceeded my expectations. 2500w - 5000w max

          Ran building AC power tools off it all day. Never missed a beat.

          *Make sure you get a pure sine wave inverter.

      • rooster7777 on 10/09/2024 - 16:33

        The ad states up to 6 parallel and 6 series connections. This brings up alarm bells to me…. most cheap lithiums state no series connections.
        The relevance is (I believe) in the voltage rating of BMS components. One battery alone only needs a bit over 24 volts rating on components… but 6 in series is a bit different.

        I talk about the problems of series connection lithiums a bit ruefully… I bought 4x12v lithiums that had been advertised as connectable up to 4 in series, for use as a 48v battery bank (supposedly good brand batteries at north of $500 each) . Overall it has not been a good purchase…. while individual battery cells probably remained in balance, different batteries went wildly out of balance. The ramifications were if I tried to charge at a reasonable voltage, some (differing) batteries went very high voltage, others being low. They chopped and changed like ants on fire. It was very hands on at the charge voltage, before one finally crapped itself….and I'm talking about trying to charge @ 4x14.3V = 57.2V, when they were supposed to be able to charge at 14.6V.

        • tunzafun001 on 10/09/2024 - 17:06

          Interesting..but I can see how it would go belly up if there is no way to keep them balanced across packs.
          We have home solar batteries..and they need to be within 1% of each other at all times.

          • rooster7777 on 10/09/2024 - 17:17

            @tunzafun001: nodsnods
            to run as a battery bank, I reckon the pragmatic option is to gut all the batteries, put the cells in a common container, and run a 16s BMS… and in a deal like this, where cells are probably seconds…. to have a few fat amps of active balancing as a BMS feature.

        • Igaf on 10/09/2024 - 18:09

          In one of the videos I linked the bloke couldn't even get one battery to balance after charging. Given the variable and unknown quality of the cells you might get two good ones and you might be lucky with the BMS amanging two in series but probability is that one, or both, will deteriorate pretty quickly. To avoid disappointment the low price should be accompanied by low expectations.

  • BuyoTheCat on 10/09/2024 - 16:00

    would this be a legit product? at $289, it is almost "too-good-to-be-true"

    • battler on 10/09/2024 - 16:03

      more in market at similar price point: https://www.ozbargain.com.au/node/865782

      • BuyoTheCat on 10/09/2024 - 16:07

        those have always been under/around $200 because they are lower quality (but still good for the price) pouch batteries

        VoltX batteries are usually around $400 and are regarded to be higher quality

    • Igaf on 10/09/2024 - 16:30
      +1

      VoltX get decent reviews. They don't say what quality the prismatic cells are - probably low grade or failed to meet A grade spec- but with a "5 yr warranty" at this price possibly doesn't matter for recreational use.

      This review trashes their BMS balancing. https://www.facebook.com/alloffroadau/videos/new-2022-voltx-… His teardown showed a battery (BMS) failure, can't find any update: https://www.youtube.com/watch?v=XOSnaGev07E

      Voltx's website is threadbare. Anyone bought one of their LFPs? If so did it arrive with details of the 5 year warranty? Pro-rata? Replacement with equivalent product?

  • jjsnacks on 10/09/2024 - 16:03

    Nice, been looking for a pair of these to run in series to power my house during power outages

    These actually state they can be run in series whereas the ones in the other deal don't recommend it.

    • Keplaffintech on 10/09/2024 - 16:46

      wouldn't you need 20 of these in series?

    Even better at $159 (read the text). I did have that in the title but apparently not wanted.

    It scores good reviews if you look around. I ordered one last Friday. It arrived yesterday and looks good. Based on its quality look but mainly the cashback deal I ordered a second one.

    • HappyPants on 10/09/2024 - 16:07

      Do you happen to know if these use pouch cells, like the Gentrax?

      • jjsnacks on 10/09/2024 - 16:08

    • team teri on 10/09/2024 - 17:41

      Did it come with warranty information?

      Even on the VoltX website there is some confusion, at the top they say 3 years, in the specs they say 5 years. When I last looked (many moons ago), only the Pro had 5 years.

  • anthman on 10/09/2024 - 16:10

    • Igaf on 10/09/2024 - 16:34
      +1

      The teardown I linked above showed no cell info at all - dates, QR codes etc. Price reflects that. "5 yr warranty" is your fallback for a low quality BMS and cells.

  • YipD on 10/09/2024 - 16:11

      In series? The BMS is probably not up to balancing batteries in series. Best to contact VoltX.

    Being picky, the sellers description is quite creative, lol

    It's designed to last for up to 4000 life cycles and provides 100% of capacity for maximum output with every use

    Not a hope in hell of getting 100% of capacity at anywhere near 4000 cycles like they imply….

    The durable aluminium casing ensures durability and houses prismatic cells

    The prismatic cells have a thin aluminium casing and they're housed in a plastic outer battery case….

      Not to mention the "6 batteries in series" from the ad. I bet individual battery balance in a battery bank would vary wildly…. even if you regularly top charge them separately.

    • Igaf on 10/09/2024 - 16:43

      Yep, check out Phil's teardown here: https://www.youtube.com/watch?v=XOSnaGev07E

      He's previously mentioned on FB that cell balancing on VoltX Plus can be problematic beyond 80% DoD (so every charge will effectively reduce the life of cells not getting fully charged), but each battery probably differs because if the low grade cells used and you might get a good one (his video -above - of the basic 100Ah surpridingly came with perfectly balanced cells).

  • MrrMagic on 10/09/2024 - 16:28

    Hmm wonder if these would be work on my caravan

    • Dabbler68 on 10/09/2024 - 16:34

      That is a very common purpose and the reason for my purchase. 100 amp maximum discharge rate (common for lithiums) will run fridges, lights, pumps, etc but not a microwave or portable electric stove or other high current draw appliances. Two batteries would solve most of those.

      • MrrMagic on 10/09/2024 - 16:35
