Finding a budget lithium battery for camping is a mindfield. Jaycar/RTM were recommended by my uncle who's bought and used them for 2 years so far, has about 30 year in EV and is quite frugal.

$600 is a good deal imo for a brand that has stores all around the country and who honor's warranty claims should things go wrong. 36 Months Warranty.

I can't find any extensive reviews, if anyone can find one or has experience with the brand, comment! I'm assuming it's compatible to the likes as Renogy which is currently at a similar price point.

    If you want a slimline 100ah you could get one of these for $200 less https://www.4wdsupacentre.com.au/batteries/100ah-slimline-li…

      Good price considering it has a 100amp continuous BMS vs the 50amp of the Jaycar. Maybe even worth creating a deal post for this.

    • Tiggrrrrr on 05/10/2023 - 15:23

      Cheers! Probably don't need one, but I can get scolded later.

    • Igaf on 05/10/2023 - 22:46

      Likely a case of ygwypf. They 'never' say what cells or BMS are in their products. Didn't see any warranty info on the link but if it's decent and your battery reliance isn't critical then at the price it's probably worthwhile. A lot of cheapies fit that category.

    I have some experience here so will chime in.

    Jaycar (Or any generic brand of Lithium Batteries) will just private label a standard design, meaning they did not design this battery from scratch but use just a generic design from any number of manufacturers. The Battery Management System (BMS) can vary from cheap quality to super high quality, apart from the cells this is the most important part of the battery.

    Let's look at the specs:
    100Ah capacity, 50A continuous discharge, rated at 1500 cycles @ 80% capacity.

    This is actually not great, the best batteries are able to do 100Ah continous discharge and up to 6000 cycles @ 80% discharge. The Renogy battery in particular is an in house design and they have been proven to be really well made with high quality cells and BMS. In general, the higher rated battery discharge current and cycles, the better quality the cells and BMS that is being used.

    Don't just fall for the cheap price, because a lot of these batteries are the same as the no-name $300 ones selling on ebay.

    Just my 2c.

      Would you recommend this one from Renogy? $499, 100A BMS, 5 years warranty.

      Was your brand recommendation a personal opinion, or are you associated with Renogy in some way?

      • croseks on 05/10/2023 - 10:27

        I have no association with Renogy, but there has been videos online with a complete teardown so you can see how its made and its pretty good quality components.

        I have no particular brand preference as this changes so quickly but for example these are good quality and cheaper then the Jaycar: https://www.aussiebatteries.com.au/giant-100ah-lithium-deep-…

        • team teri on 05/10/2023 - 10:42

          Totally different beast, but what's your opinion on this type of setup, 48V server rack, and ATG as a brand?

          A lot cheaper than your typical home batteries, and at 48V totally legal for a DIY install…

          • at9 on 05/10/2023 - 11:37

            @team teri: From memory it won't be ok for DIY as low voltage is considered 48v and under, but this is based on the the max voltage of the system which is 57.6v when fully charged.

            • team teri on 05/10/2023 - 14:58

              @at9: "Extra low voltage (ELV) means voltage of 50V or less (AC RMS), or 120V or less (ripple-free DC)."

              Since this is DC, even 2 in series would still be ok. I don't think they are rated for series operation, but you can have up to 8 in parallel, giving a whopping 40kWh of storage.

              At half the price per kWh compared to a Tesla Powerwall, this gets a lot closer to make economic sense. Especially when being able to save thousands on installation costs in addition.

      Yeah no way would I pay this for a JayCar 100ah, as you point out the specs aren't great to begin with.
      At that price I would get a Renogy that has been torn down and shown to be a quality battery, only thing about Renogy is I have read they aren't great at honoring warranty when things go wrong. Jaycar are normally good with warranties so that is a bonus but not for this price.

      These batteries are a bit of the wild west. I bought a SolarKing 100ah a couple of years ago, it is a good battery, come with 5 year warranty by Low Energy Development which have been a reputable store for many years now, but now they have changed their business to Preston Off Grid and who knows how'd I'd go making a warranty claim if an issue popped up.

      The specs say one thing, the images of the battery itself say another.

      Even if you download the spec sheet, zoom in on the battery picture. Discharge Current: 100A, Peak Discharge Current: 150A (same as product image).

      Would probably have to see one in person and do some testing to see which is actually correct (perhaps they have more than one version and are lazy about updating their product images?).

      I would find it rather offensive if the battery itself says 100A discharge with peak of 150A but can only achieve 50A/100A. They might want to change the label if they haven't already.

      • croseks on 05/10/2023 - 10:22

        Probably just a generic image that isn't of the battery thats for sale.

        Somebody needs to do a teardown to really see whats inside.

    Some great comments above.
    Does anyone get nervous about having lithium batteries camping with the recent news about electric bikes bursting into flames?

  • AmperSand on 05/10/2023 - 10:09

    Jaycar had these on sale for $399 not long ago.

    • edfoo on 05/10/2023 - 10:20

      Do you have that link? Don't recall it ever be that cheap.

  • rooster7777 on 05/10/2023 - 10:32

    Something to be aware of- data regarding the internal battery BMS can be critical, but is missing completely on the website, specs, download, and battery label.

    Reputable lithium batteries give information on maximum series and parallel battery connections.

    Why? If you connect say 4 of these in series, BMS face greater voltages than a single battery, leading to failure of the BMS if operating overvoltage. (48V is greater than 12V).

    Most lithium batteries will give max connections….and many can't be connected in series, or they will overvoltage and fry their BMS.

    The fact that there is no such data for these batteries is an indicator of very poor marketing…. leading to questions about their quality.

    The Renogy 100ah battery is only $499 on their website, and has 100A continuous output and 5000 cycles. Even cheaper through third party sellers on ebay. https://au.renogy.com/core-12v-24v-48v-100ah-deep-cycle-lith…

    Done some research and found this. Have not purchased the battery but have their battery box and the quality looks first grade.

    Thanks for all the informative comments and feedback! I think I'm now leaning towards the Renogy. Could someone help point out the difference or preferable battery between the following:

    • Igaf on 05/10/2023 - 22:33

      Suggest you research Renogy "warranty" and customer service in Australia. May have changed since I last looked > 12 months ago but was pro-rata. Plenty of other makers replace within the warranty period. Any decent 12v LFP properly managed should have a statutory warranty (ie full replacement) of at least 3 years. Their customer service here WAS problematic according to some comments I read.
