The Rock-12-120 lithium battery is safe and reliable whilst being small and lightweight, with a long life and fast charging. Comparing the Rock-12-120 lithium battery with similar batteries, the volume and weight are around a third and a half respectively than that of ordinary lead-acid batteries. The build in battery management system(BMS) provides multiple protection: over-charge, over-discharge, over-current and over temperature. The Rock-12-120 lithium battery will last at least 2000 full cycles before minimal performance changes. This means it can last up to seven years, depending on the frequency of use. It can also be charged and discharged under high current without affecting its expected lifespan. The Rock-12-120 lithium battery can be used with solar inverter, vehicles, electricity grid and many other charging methods. It is very suitable for use in various vehicles, such as electric boats, caravans, RVs and so on.

    Country/Region of Manufacture: Australia, is it?

      Are you joking? Of course it isn't Australia, there aren't any LiFePO4 manufacturers here so the main component, the cells, must be made elsewhere. China is by far the biggest producer and produce some excellent (and lesser) cells. Obviously this will be made in China too.

      • m9 on 16/08/2023 - 12:09

        They're referring to the listing

        Edit: Rep has now changed it to China.

      It's China Manufacture and has Certification IEC 62619.

    Good grief, that is cheap. Even cheaper than Kings.

    What does Bluetooth get you?

      You can use the mobile APP to connect and check the battery situation at any time.

        No sure why you shared the link, the description is exactly the same for both versions, and didn't explain the Bluetooth functionality at all.

        Thanks for letting me know though.

          Likely hasn't got a clue about what can be done with it. Good battery mgt systems will allow users to change parameters as well as observe battery status. Hasn't bothered to answer my question about the BMS or cell type either. Suggests he doesn't know or doesn't want to expose its limitations. Imo consumers of cheap LFPs probably understand they aren't getting very good products and are happy to live with that but it should be their choice based on REAL and ACCURATE information. Some of their batteries specifically state "Tier One Prismatic cells (presumably claiming the cells are from a factory 'Qualified to supply multi-national electric vehicle producers outside of China' while not stating the grade of the batteries), but not these. Could be used, could be pouch… we don't know, Caveat emptor.

    Cycle Life > 2000 Cycles

    is pretty meh. Most coming out these days are 4000 cycles.

    • Stevesie76 on 16/08/2023 - 12:57

      I'm not sure how meaningful that vague cycle rating ever really is though. The cycle life is highly dependent on how the battery is used.

    • ConsumerAffairs on 16/08/2023 - 13:15

      Depending on what Depth of Discharge percentage they're quoting, some have 6000+ cycles but at only 20% DoD.
      Most are around the 2000 cycle mark when the DoD is going down to 80% or more.

      • Hyena on 16/08/2023 - 13:40
        +2

        Even 2000 cycles is 5.5 years if you fully charge and discharge it daily, which the vast majority of people will not do.
        I figure in 5 years time lithium battery tech will have progressed such that you'll want to replace it with something double the capacity and half the size anyway.
        The other caveat with batteries at this price point from China is it's common for them to use second hand cells from old EVs or whatever and just downrate them. Eg a 120ah battery may well be made from 150ah cells that are already years old and dropped their 80%, but will still give you another 2000 cycles odd while gradually continuing to degrade

        • ConsumerAffairs on 16/08/2023 - 14:35
          +2

          Fully agree, you've also highlighted another issue with how these are rated. Any legit seller using second-hand cells will quote what grade i.e. A, B or C on the cells they're potentially using. It really is a true gamble buying these batteries.

          • Hyena on 16/08/2023 - 14:42

            @ConsumerAffairs: "100ah LiFePO4. Made from C grade cells that were getting a bit sh1t in the old bus we pulled them out of, but should run your LED lights and camp fridge for the next few years just fine"

      2000 is plenty, if you uses for off grid camping that could easily outlast your van/tent, by the time capacity degrades to less than 80% you could have a new one with double capacity at less than half price.

      • watts on 16/08/2023 - 23:30

        Exactly why I didn’t stress about cycles when getting a new battery for my camper. It’s lucky to get out 20 days/year and lasts a few days per charge so the battery should outlast me.

  • LePhasme on 16/08/2023 - 13:09

    Are they fine to be put in the engine bay or will it be too hot for those ?

    • Cpt Archer on 16/08/2023 - 14:05

      I would not put a LFP battery under bonnet. Best case, battery will prematurely die.

      I did, no problems so far.

      • AMLagonda on 16/08/2023 - 16:23

        yes but it will shorten its life…

          I got it cheap, and have no other space for it.

  • harry2008 on 16/08/2023 - 13:43

    Hey Rep,
    Any 100ah options available to be used with trolling motors for a small boat?

    • Marketingedgepower ecorridor @ ECORRIDOR on 16/08/2023 - 14:32

      Yes, this battery can be used.

  • iamprabhath on 16/08/2023 - 13:46

    Both of the links are pointing to the same battery without the bluetooth .. can u please update OP..

    Deal says 120Ah, your specs say 100Ah here and on your website. Think you need to do some QA .

    What sort of cells are used in this battery and what is the BMS?
