    i assume you need to buy a battery box for these?

    • shiftyphil on 02/03/2020 - 18:17

      Depends on what you are doing with it. A box provides protection, and usually a few connectors.

      If you are using it outdoors, most likely needed.

    • 0jay on 02/03/2020 - 18:51

      Boxes are generally a rip off, often don’t fit well and don’t really offer much beyond connections and containment.

      LiFePO4 can be stored and used in any config (don’t have to be upright and do not emit gas) so are stashable in ways other chemistries are not.

  • wombat81 on 02/03/2020 - 18:20

    Any comments on the quality of this brand?

  • tessel on 02/03/2020 - 18:41

    I'm confused. Are they saying only discharge to 50% of battery capacity? If so, that sounds a bit off for a lithium battery. That sounds like a deep cycle AGM. I do understand that discharging less will prolong the life of any battery but one of the selling points I thought of lithium was you could discharge more safely.

      Where are you reading discharge to 50% of the battery capacity?

      • tessel on 02/03/2020 - 19:00

        My apologies, forget my glasses. All good :-)

    • 0jay on 02/03/2020 - 18:48

      LiFePO4 is a different chemistry to regular lithium batteries and different again from AGMs.

      LiFePO4 can be discharged to 20% capacity and could last more or less indefinitely if looked after. They can be exhausted and will still last better than a comparable AGM or conventional lithium equivalent.

      • incipient on 02/03/2020 - 19:11

        Wikipedia disagrees with you on that. It states 2000 cycles as an average life for an LFP battery.

        Shelf life however is stated as ">10 years".

        • 0jay on 02/03/2020 - 19:17

          Exhaust it and you’ll get around 2000 cycles is what manufacturers will guarantee on.

          Baby it and they can last indefinitely meaning the batteries tested in this manner are still in service.

          It’s a reasonably new chemistry so there’s not a whole lot known about their lifecycle under different conditions.

      • nfr on 02/03/2020 - 19:43

        How to look after it?

        • alvian on 02/03/2020 - 19:50

          Disconnect and put it in a padded storage box in a climate controlled warehouse.

        • stumo on 02/03/2020 - 20:12

          The best way to baby these is to never fully charge, and never fully discharge. Just stay within the middle 90% of the battery, and so avoid the "knee" voltages at either end of the range where the permanent damage occurs.

    • Stevesie76 on 02/03/2020 - 19:00

      It says you can use the full 105Ah capacity. The maximum current draw is 50A.

      • 0jay on 02/03/2020 - 19:09

        You can but there’s a tradeoff.

  • Nitrollparty on 02/03/2020 - 18:57

    careful with these cheaper batterys, they tend to go bang. since these are such a low current too, kinda useless in a 4x4 if running fridge/lights/solar

    • ob123 on 02/03/2020 - 19:06

      Are there actual examples of LIFEPO4 batteries going bang?

      Also, 50A is plenty for a fridge (6A Cycle) Lights (10A Typical LED). It’s the 2000W inverters this isn’t suitable for.
      Hell this could even run a 12V oven (18A) along with the fridge and everything else at once…

      • fantombloo on 02/03/2020 - 20:15

        Not bang but I have had a prismatic cell smoke and catch fire pretty quickly. A properly sized breaker was fitted. Can only surmise it was a manufacturing defect or some very quick transient that didn't trip the breaker.

        • ob123 on 02/03/2020 - 20:45

          Was it LIFEPO4 though?
          I’m asking becuase I actually do run a LIFEPO4 inside the car - in the footwell behind the drivers seat inside a battery box.

          LIFEPO4 is meant to be a really safe chemistry so if there are examples if the batteries going bad I may need to redesign the setup.

          If smoke filled up the cabin of a car while going 110km/h that would be a major hazard

            @ob123: Yes it was. It was in an existing design with a BMS but had no cell balancing, and it occurred on discharge.

            Compared to other Li they are safe; a fire is much preferable to a bang. This was one cell out of many (like over a hundred) that I've played with.

            I've had some experience with cylindrical cells leaking over time and I would have much less confidence using them again. But prismatics with a proper BMS including some individual cell management and I'd be pretty confident.

            • ob123 on 03/03/2020 - 09:35

              @fantombloo: Thanks, very informative first hand experience.

    • [Deactivated] on 02/03/2020 - 20:06

      should be fine for a few days with a fridge (they use 0.7-2Ah). solar will keep it topped up.

    • willyroo on 02/03/2020 - 20:10

      Our maximum draw was 14 amps:

      • Evakool Fridge 5.2 amps start up
      • Water pump 4 amps
      • LED lights just over 3 amps (36 watts gets good lighting on a camper trailer)
      • Phones around 2 amps (roughly equivalent to 5A @ 5V)

      So I reckon 50A max should leave plenty of overhead for most campers…

  • Stevesie76 on 02/03/2020 - 19:03

    This review doesn't seem to promising https://www.youtube.com/watch?v=FE4kDB3t7Ck but it's missing any actual proof of capacity so it could be a competitor.

    • bentley on 02/03/2020 - 20:00

      I had a look at the video . Maybe he was testing max amps which the BMS will cut off at 50a. It's not a starter battery which will draw 300amp easy. It's a storage battery that will give yo 20amps for 5 hours every day for 6 years (maybe!) I have ordered one and will test it for capacity.

      • geekboy on 16/03/2020 - 19:26

        These are on 20% off at the moment so I'm a little bit tempted. How did your capacity testing go, are they a hit or a miss?

  • Jenny Death on 02/03/2020 - 19:04

    So in general im assuming you need an electrician to hook one of these up to an existing solar installation (in terms of legality)

    • incipient on 02/03/2020 - 19:08

      You'll need an electrician to do any work over 48V I believe is the cutoff?

    What is the Cell type? Prismatic or Cylindrical

    • 0jay on 02/03/2020 - 19:10

      Prismatic’s what you’re after.

  • vbt on 02/03/2020 - 20:33

    Wow! 3-4 times cheaper than a proven Lithium battery.

    How do they do it? :)

  • WV1 on 02/03/2020 - 21:30

    Be careful of this guy selling these. I purchased a folding solar panel from him rated at 120W for a caravan. Turns out it was a cheap panel with an o/c voltage of 12v meant for irrigation systems without a controller so could not charge a 12v caravan AGM which needs around 14V to fully charge. I got my money back but he continued to sell to unsuspecting customers on Ebay.
    When I left negative feedback to warn others he had it deleted. Did not even show up as revised just deleted, shows you what power sellers can do to to rig ebay. You have been warned.

    • antojamo on 03/03/2020 - 08:43

      Seems to be a similar pattern with all the -'ve feedback for this company on eBay.

  • herbo on 02/03/2020 - 22:13

    I have been considering this lithium battery

    I know more $ but seems to be a reputable seller who has a good rep on whirlpool forums amongst the green energy mob there, eBay coupons sometimes work on them.

    • antojamo on 03/03/2020 - 08:45

      I'm not familiar with SolarKing, but you could spend a little more and go for Renogy. I've been looking for a lithium battery for a battery box and Renogy seem to well regarded.

    • ob123 on 03/03/2020 - 09:41

      We have a 100AH SolarKing running in another vehicle. It's the older design with the cylindrical cells (should be the same as your link).

      Has been completely flattened once on a long trip bad bounced back fine and not exactly well taken care of - we used a AGM Charger during the first few years of its life but now have a proper Lithium Charger.
      Its coming up to 2 years now and no issues, lasts for 3 days running the fridge only.
      - I would recommend but I also bought from a brick and mortar shop so I could return easily for the 3YR Warranty..

    • Bob81 on 03/03/2020 - 13:37

      I have a 150AH solar king and it works a treat. Highly recommend.

      If you can hold out buying your battery for a little while, they are often on sale at Rockby Electronics for less. https://www.rockby.com.au/SearchresSql_12.cfm?Searchkey=100a…
