          nope. All your charging equipment will need to support lithium for it to work.

        • DonWilson on 03/09/2022 - 16:28

          Not sure why Ahbal was downvoted, they're right.

          The most likely incompatibility is your charger. You'll damage a lithium by charging it using a lead acid/deep cycle charger. You need to check whether your existing charger has a lithium setting and if not you'll need to replace that too.

          You also want to make sure you're not regularly drawing more than ~50A/1,000W from the battery. It's incredibly unlikely you are with a fridge+pump+lights but maybe there's something else you didn't mention.

            @DonWilson: yeah no.. These are designed as a drop in replacement for SLA. LFP have a higher voltage, and you can use the SLA charger without damaging your lithium. However as you are charging to a lower float, you will get less capacity , approx half of the battery.

            LFP have a BMS to manage the charge / discharge, so you can't break it using a "different charger"

            • DonWilson on 03/09/2022 - 17:10

              @rooster: You're technically correct. I stand by my statement that Ulven is likely to damage it if they try it.

              • Ulven on 03/09/2022 - 17:50

                @DonWilson: Appreciate the insight. I was hoping it would be a simpler option but I guess not!

        • miicah on 03/09/2022 - 15:47

          Yes. The only risk is piercing the metal casing (and a cell) and ending up with a lithium fire.

        • SeVeN11 on 03/09/2022 - 20:46
          +2

          LFP are pretty safe, if you have an accident, the fuel in your car would be way more flammable and dangerous than the battery exploding from being crushed/pierced.

          If the battery is being crushed, you would likely be crushed too.

          • Jeff1001 on 03/09/2022 - 20:53

            @SeVeN11: right, do i still need a battery box for it? the space under the seat is small for any box, it is okay for the battery only

              +1

              @Jeff1001: That's up to you, but you'll have an exposed +ve terminal that you might want to cover up.

              Similar to your car battery, you don't want to drop a spanner or any metallic object between the terminal or between the +ve to the vehicle chassis.

              As long as you insulate that +ve terminal so you can't short it, you'll be fine.

    It's a pity these aren't the same VOLTX 100A LiPO4 batteries that ALDI had for 429. For some reason no one else has ever had the same model and they can do 4 in parallel.

      • yogihogi on 03/09/2022 - 16:12
        +1

        No not the same Aldi ones had 100A continuous discharge rate and could be setup in series or parallel. These are a cheaper version

        • lulzenberg on 03/09/2022 - 16:41
          +1

          According to VOLTX support they only support 4 in parallel, not in a series, and 50A continuous discharge.

          If you've got something that shows they can do series and 100A continuous I'd be interested in it, as while I got the above information directly from their support team, it was after about 15 emails of them telling me they didn't support Parallel, with me questioning this as it mentions parallel functionality directly on the battery itself, and then them finally coming back and apologising and saying that they did, so I wouldn't be surprised if the 50A & Series information wasn't entirely accurate.

          • SeVeN11 on 03/09/2022 - 20:51

            @lulzenberg: I have a cheaper eBay LFP, and they say you can't put them in series, but I do and it works fine in my application.

            The reason why they say you can't put it in series is because if the batteries are not balanced one of the battery BMS might turn off due to high voltage protection and you'll end up with an open circuit.

            So depending on your application you may or may not care about this.

            How I overcame this is to simply not charge it to 100% and I also balance the battery every 3-6m.

          • yogihogi on 04/09/2022 - 10:42

            @lulzenberg: Your probably right I use voltx to run all 12v gear( lights, water pump, freezer) and use it when I take out the kayak.
            Have my 140ah deep cycle separately running inverter for tools and cooking. Was hoping to simplify setup so as to not have to run 2 separate systems and for weight saving. Looks like I should keep it as is.

        • edfoo on 03/09/2022 - 17:02

          No, Aldi's VoltX is the same as this, only has 50A continuous discharge rate.

          • lulzenberg on 04/09/2022 - 14:59

            @edfoo: The continuous discharge is the same, they aren't the same batteries though - the ones from ALDI can be put in a series, you are still limited to 50A continuous discharge though.

          Mine from Aldi (has Aldi gurantee screen printed on battery) has only a 50A BMS. It is not printed on the battery or the box it came in but the user manual it came with (have battery, box and manual in front of me) says "Standard Discharge Current 50A", "Max Continuous Discharge Current 50A" and "Max Discharge Current 5 seconds 100A".

    Everglow 12V 100Ah Lithium Iron Phosphate Battery LiFePO4 Rechargeable Deep Cycle

    • SeVeN11 on 03/09/2022 - 20:56

      I got the everglow for $270 about 6m ago with the eBay 22% discount and I been using mine daily over the last 6m. I use 40A @ 40Ahr each day for 6m and they are still going.

      I also tested the capacity and it was close to 100Ah. From my google research, they should be recycled cylindrical LFP either used in street lights or electric vehicles matched with the cheapest BMS China can produce.

      Just make sure you test the capacity and load when you buy it.

    • tanksinatra on 03/09/2022 - 21:12

      I bought that one from ebay for about $280 some months ago. When I tested it I got ~106Ah. Very happy with it. Just be careful with the load rating, I've read that they don't have overcurrent protection and can burn out.

      • SeVeN11 on 03/09/2022 - 22:50
        +1

        I'm not sure how the over current protection works in the BMS, but I've definitely drawn over 50A for more than a few minutes without any fuse and it still worked. It is rated for 100A max draw for 5 seconds.

        Best to just put a 40 or 50amp fuse just incase if you're scared.

          Agree. A fuse is a good idea. It would be a lot easier to replace a fuse than opening a battery to replace a cooked bms.

    I got this brand as a 120ah from ebay on sale at $365 and has met my needs and preforming well. Needed new dc/dc charger and a new mppt charger for solar. As stated canno run parallel with other battery according to specs. Also 120a has 100a bms.

  • turbodude on 03/09/2022 - 18:22

    I have this from Aldi. It looks identical but may be a variation as is states on the battery itself: "Up to 4 identical batteries in parallel" whereas current specs say no parallel. My guess is that there may be variations of this sold over time with different BMS's. Mine has a 50A BMS and has an Aldi guarantee screen printed on the battery along with the rest of the specs. I have load tested it with about 35amps and got a capacity of pretty much dead on 101Ah but the BMS doesn't shut off until lower limit of 8.75v which is a bit low.

    Interestingly the BMS current is not printed on the battery or the box it came in but the user manual it came with (have battery, box and manual in front of me) says "Standard Discharge Current 50A", "Max Continuous Discharge Current 50A" and "Max Discharge Current 5 seconds 100A".

    Seems to be a good battery for fridge, lights, basic charging but as others have said 50A BMS limits it to only small inverters.

    The poor quality battery management system and B grade prismatic cells will severely limit the claimed life of these units. Live off-grid with 15kwhr LiFePo4 48V storage bank. Wouldn't feel comfortable about the life of any LiFePo4 battery if I couldn't see the voltage of each cell to 1/100 volt precision. In general keeping the battery state of charge between 30% -90% will help with longevity. Also I would not push the charge voltage beyond 3.5V per cell (14.0 V). This is > 98% charged. As LiFePO4 cells age they will unbalance and the useable capacity will decrease and the risk of shutdown by the BMS increases. The BMS specs are not known and I suspect there is no (or insufficient) balancer component at this price point. Poor quality BMS is why they can't perform reliably in parallel. If theses batteries don't die early and can get even 1000 cycles at 60% then you are probably ahead.

      I've got two everglow cheapo ones and use it in series with no problem, but I only change the from a UPS with a AGM charge profile so it doesn't charge it to 100%.

      I've also done about 200 cycles drawing about 40% on them over the last 6m.

      For most people who just want to replace UPS batteries or just power a camp fridge and LEDs during school holidays, weekend etc. Its more than sufficient.

      Charging them with a normal AGM charger is fine too as long as it's below 14.4V, I use to charge mine with a $5 buck converter powered by a laptop charger and it's fine.

      There's no need to spend $2k for battery + lithium dcdc + lithium mppt solar etc. Just to power a fridge for a long weekend trip.

    What can I use to charge a LiFePo4 battery from a car cigarette outlet?

    I have had a VoltX 100ah from eBay for more than a year to power my 47L camping fridge 24/7 it stays on even when I'm home (plugged into AC when I'm home).

    So far I've been using a Victron 15A AC charger to charge my battery when I'm home, but I'd like to be able to charge it from the car's cig outlet while driving too.

    Any specific product/links?

      To charge an auxiliary lithium battery properly in a car, you will need a setup with a DC-DC charger.

      • tanksinatra on 05/09/2022 - 18:02

        Yeah that's what we are looking for, a DC-DC charger powered from a cigarette socket. It would have to be around 10a obviously.

        • edfoo on 05/09/2022 - 19:28

          I don't know of any DC-DC charger that can be powered from a cigarette socket. Most of them required wiring connection from the car main cranking battery.

    • zombie hunter on 05/09/2022 - 19:34

      Since got a victron charger, get a victron dc-dc charger and wire straight to the car battery. Don’t abuse poor ciggie socket. Not designed for that.

    • bargainshooter on 05/09/2022 - 20:07

      A cigarette socket will only supply 12v and generally less than 10a. When it starts pulling a charge it will most likely blow the fuse. Most dual battery car systems are connected to the main battery via an isolator (voltage sensitive relay) to only supply a charge over 13.x volts, so only when the engine is running. You need more than 12v to charge most 12v batteries. But you could set up the isolator to output via a separate cigarette lighter socket if you want to use that type of connection. The better alternative is to use Anderson plugs rated for your requirements.

    • McScotty on 05/09/2022 - 22:33

      I use a 12V inverter connected to the boot cig lighter, paired with a 10A, 240V charger in my 2020 RAV4. Because the charger doesn't draw more than 10A, there is no risk of blowing the cig lighter fuse.

      It's a soccer mum car - I have no interest in pretending it is a 4WD. I occasionally go on long road trips or go to Costco before visiting my parents for a whole day, so the convenience of a fridge+battery is nice, with the modularity of a few pieces working together. No issues with warranty or cutting trim/running cable, either.

      It's also super handy having an inverter and charger in the car, often I'll power my laptop while I sit and wait for the missus to finish work.

      You asked for specific links (I keep tripping the referral link thing, ugh.)

      I reckon you could find cheaper on the charger, not much more to be saved on the inverter though.
