    This is about half the price of the cheaper 100ah LiFePO4 units, I’m very suspicious. Also being sold via Kogan, catch, and a few other spots that doesn’t inspire confidence.

    Reviews are mostly “wow this is so cheap” superficial stuff but one person claimed to test and said capacity was 60ah not 100ah.

    • [Deactivated] on 03/06/2022 - 12:36

      one person claimed to test and said

      link? Some persons cannot measure (profanity), lol

      I got my 100ah for $250, still doing good, from jewelleryidea ebay.

      • enigma48 on 03/06/2022 - 13:33

        Pretty sure it was an eBay review but don’t have the link right now. It wasn’t a detailed post, just that their capacity check showed closer to 60ah.

        You’re right - most people don’t have the gear to test this properly, but most 100ah lithium batteries 50% cheaper than their competition tend to exaggerate their capacity. I don’t know which one is true in this case.

      But the picture says 100% real capacity 😁

    Seems a bit light for 100AH, li-ion or not…

      1 100ah 3.2V cell is 1.9kg, x4 = 7.6kg cells only. Case and BMS at 1.2kg? probably.

  • BuyoTheCat on 03/06/2022 - 12:45

    is there any way to check if the battery is really 100AH?

    • [Deactivated] on 03/06/2022 - 12:48

      Yea, you need this meter https://www.ebay.com.au/itm/333140454916, some 12V load and patience

    • CletusDB on 03/06/2022 - 12:50

      Add 1 amp load and wait 4 and a bit days?

      • peter_mcc on 03/06/2022 - 13:13

        5A and wait 20hrs would be better - I think capacity is usually measured as 20Ah.

        Remember also that a 100Ah battery doesn't have 100Ah of usable capacity - it will disconnect with 10-20% left. If it was a Lead Acid battery discharging it below 50% regularly greatly reduces the battery life - LiFePo4 batteries can discharge further but eventually the BMS will disconnect to protect the cells.

        • at9 on 03/06/2022 - 13:59

          It should still pull 100ah the BMS shuts off when any cell hits 2.5v which is when a LiFePo4 cell is empty. Not running down to 2.5v will lengthen the life of the cell but you are talking 3000 cycles vs 2000 cycles. That being said these will defiantly have used cells so will degrade faster.

  • Italkdigital on 03/06/2022 - 13:08

    Whats everyone using these for?

    Was thinking of (if there's the room) as a battery backup to my car battery,. well to use it to run things for long use, like hours apon hours instead of using my cars main acid battery, well you can't kill these running to say 20% capacity as a lead acid battery, even worse almost dead flat,..anyone's thoughts, what seek medical help lolz

      I use mine for my caravan and aux battery in my car. My 100ah AGM was 30Kg and only got about 60ah out of it and took so long to recharge. My 100ah Lithium (not one in this deal) is 12kg and I get close to 100ah at 12v out of it.
      same for my car, run the fridge from my Lifepo4 so the start battery doesn't discharge.
      I'd never put a lifepo4 in my engine bay as they aren't designed for high heat or amp draws.

      • Uncle BucK on 03/06/2022 - 13:25

        I recently did a similar thing. Bought a battery box and a dcdc charger to charge a lithium battery from the alternator and then run a fridge from it when camping etc.

      under bonnet install with Redarc DCDC charger for powering portable fridge

    • Timm on 03/06/2022 - 14:39

      I use a 100ah LiFePo4 battery and a battery box to power a 12v fridge and charge phones etc while camping. With the battery fully charged and the fridge pre-chilled I can go for 3-4 days without charging.

    These cheapies are usually built with 2nd hand or B grade cells that may initially show the advertised capacity, but lose this within months to become basically duds within a year.

    You definitely won't get a real 'cycle life' of 2000+, maybe 20 - 100 if you're lucky.

      And seriously, how do you know that? Super-fast degradation of LiFePo4 cells with initially correct capacity? I'd love to see where it is coming from.

    "Connect In Series Less than 2 identical batteries
    Connect In Parallel Less than 2 identical batteries"
    I don't understand.
    Less than 2 is 1.
    How can you connect 1 battery in series or parallel ?
    I could understand "maximum of 2 batteries".

    • Mischaseb on 05/06/2022 - 09:02

      Lol, I thought the same. One would assume that it's supposed to be "maximum of two". It doesn't say whether you can do two in parallel and two in series at the same time; probably not I'm guessing.
