    The pictures in this listing are interesting - I feel like I'm being lectured.

    Nice OP! Was waiting to get another slimline battery . Got one!

  • +1

    What's with the cartoon selling shenanigans?

    Alot of info of how crap one other battery out there is (which probably isn't even an accurate representation of all out there) but not much info about what they're selling themselves apart from a few perfectly edited factory photos….

    • +4

      It's amusing they're selling a no-name battery from an unknown manufacturer but their cartoons are promoting "Choose Legitimate Manufacturers"

      • +1

        Yea my thoughts exactly! I spent too much time looking at the listing curious if they mentioned anything substantial about their 'legitimate product'

      • +1

        Yep, had same reaction

        Be sure to choose batteries made by legitimate manufacturers instead of just keeping an eye on the "low price."
        The irony.
        "Brand Not Available"
        Cells - neither type nor grade provided
        BMS - no BMS manufacturer or specification provided
        10V cutout - common, but too low

        "low price" and 2yr warranty (if it exists) is good though.

  • What's the quality like on these? I need one for behind the back seat in my dual cab D-Max and thought one of these could work well

    • I have this running on my MUX for over a year and it has been rock solid.
      Much slimmer than the one Op posted and has metal housing.

  • +1

    I wish these were able to be wired in series. Would make a great 48v reasonably compact 100ah solution for <$900.

    • Why can’t you?

      • The sellers state: "This battery cannot be connected in series"

        I assume the BMS either cant handle the higher voltage when connected in series, or the batteries vary a lot so they don't stay balanced when charged/discharged in series…

        My basic uneducated understanding > When connecting LiFePO4 batteries in series you usually use matched batteries, same brand, capacity, age, and such, so they charge and discharge at exactly the same rate.. If you connect oddball batteries in series one will often charge/discharge faster than others then the BMS will cut out before the others have charged/discharged, so the battery bank ends up all out of wack…

  • How do you hook these up to use fridge, etc. Is there a battery box..?

    • BYO Battery Box. BYO other connections/wiring etc for accessories. Depending on your Fridge there will be little pre-made adaptors/cabling you can get to make it easy. These can often be bought online or from Supercheap/Autobarn/Repco/Bunnings.

        Cheers

    • Depends on the fridge, a battery box gives you some alternate connections, maybe USB output and a container/insulation from shorts etc for the battery, not an inverter to run AC powered devices, the startup current on a AC powered fridge is manifold higher than the run current- IE my AC powered fridge uses 280 watts once it has fully compressed the gas in the condenser coil but uses over 2000 watts surge current to start, your inverter and BMS need to be up to the surge current, which "may" or "May Not" draw more wattage than the max rated from this battery momentarily depending on the fridge and whatever else is drawing current from the battery … that will make the possibility of over current draw on either device likely (battery or inverter) always over size everything.

      A DC powered fridge is different, my large DC fridge is rated at 75 watts only

      Learn from this guy

      He knows what's worthwhile and what's not.

      • Thank you..

  • Can it be a back up battery for a dashcam for EV/Hybrid vehicles?

    • With a bit of stuffing around, yeah you probably could. But depends how far you want to go.

    • +9

      This would power a dashcam for approximately the remainder of human history.

    • +1

      This is akin to having a 10 acre substation just for your one-bedroom granny flat.

    • Equivalent to using a monster truck to squash a cockroach.

  • How are these so cheap and yet have 3000 cycle rating, max 200amps 100 in and out, sounds to good to be true, with I had some $! only downside is the BMS isn't good enough for series.

  • i wonder why not in series…

    • Refer to comments above approximately 2.5 hours earlier.

  • Anyone know the life expectancy of a lithium 100ah for a dual battery setup in a 4wd (to run a fridge). Had mine (alternative brand) for about 4 years and noticing my length of fridge run time is getting quite a bit less before the battery becomes drained

    • +1

      There are graphs around showing battery capacity to cycles for various DoDs (100% being worst) but really there's too many variables involved to generalise. Eg: battery and BMS quality (what it cost new will be some indicator), cell type, usage (no of cycles completred), typical drain/charge cycle (what's your DoD cutoff, 0 or 20%?), fast/slow charge, environment etc.

      What's 'quite a bit less'? Two thirds? Half? Does that take into account how hard the fridge is currently working (obviously a lot harder in very hot conditions so significantly more Ah draw). Have you measured total Ah draw to near depleted lately? If you drained and recharged every second day (unlikely) that's only about 700 cycles completed.
