    Aside from capacity, how does this battery compare to this one? https://www.ebay.com.au/itm/304315952043

    I was thinking about getting this battery for use with a trolling motor (Striker 60), would it be okay for that?

    Thanks!

      Yes that would do it. I bought 2 of these recently and they were world apart as to when they would stop charging 14.4 vs 13.8 fab living the seller was a pain to deal with. Ebay stepped in and all was good. it seems like the quality is a bit hit and miss. I se t them both back and went a 200ah single battery. Very happy with my choice.

      • ozhunter68 on 22/12/2024 - 12:57

        That was unlucky for you, think I read an earlier comment from you stating this.

        At least you got a good outcome and you got refunded? What brand of 200 Ah battery did you

        end up getting as I am also interested in getting one in future?

    • ozhunter68 on 22/12/2024 - 12:53

      I have four of those Gentrax 100Ah batteries, and they are decent and have been proven to be reliable,

      well build and have a decent quality BMS in them. In saying that, the listed battery represents great value

      for specs if you need bigger capacity and 200Ah discharge. Not sure on this brand and quality,

      and for your usage, the 100 Ah Gentrax would be plenty and easier to handle.

    I looked at these the other day, I couldn't really find any info about them, with the 16.6kg weight I suspect they're pouch cells not prismatic, decent price though….

    I ended up spending a bit more, $414 for a 200Ah PowMr delivered:
    https://www.ebay.com.au/itm/156534333315

    They seem to be new prismatic cells and a name brand JBD BMS, screwed connections and such, teardown of a 100Ah here:

          Looks good, super fast 200 Ah max charging rate (tweaked their own BMS design),

          24 month warranty ok too. They show pictures of prismatic cells, but did not read

          that on their listing from what I see?

            @ozhunter68: Been looking at their 100Ah batteries as well. Not unusually for Chinese sellers, their claims are all over the place.

            X cycles in places, Y elsewhere. Warranty ranges from 10 years (possibly typo, lack of listing QC) to 5 years to 2 years. The images specifically say 6000 cycles and 5 year warranty.

            Also selling the 'same' battery on eBay for $255 and $229

            I've messaged PowMr and the seller in the deal - no response yet.

            • ozhunter68 on 23/12/2024 - 22:06

              @Igaf: Yeah, see your point. Can actually get the second link price for $215.79 which is great price

              using the code "DCMBR17" as the second which is accepted. I am not buying anymore

              100 Ah batteries for now lol.

      opo56565 says the Werchtay is also A grade prismatic cells, doesn't specify if new or used.

      • FLICKIT on 23/12/2024 - 21:23

        16.6kg seems very light for prismatic cells, most 100Ah 3.2v prismatic cells are 2kg each, 200Ah cells 4kg, so a 200Ah battery would be 16kg for just the cells, then you have case, BMS, wiring, and such on top of that…. But who knows, with how unreliable Chinese specs tend to be they could weigh 20kg and not the 16.6kg listed, lol

        • abuch47 on 24/12/2024 - 11:11

          PowMr battery is also smaller than Werchtay deal battery

        Not to be picky, just out of interest, where do they say the Werchtay are 'prismatic' cells?, I cant spot it…

        That was a big part of my reason for dodging them, I figured if they were prismatic cells they'd mention it, and I couldn't see it anywhere…

      Prices are definitely coming down everywhere, but without a teardown by a knowledgeable commentator, I'm not game to take a punt on a 200Ah batt. I recently got a 100Ah 'Wattcycle' as mentioned by @FLICKIT on the basis of two detailed teardowns. It has its nameplate capacity and has been doing fine (too soon for any real comment beyond that though) https://www.ozbargain.com.au/comment/15893456/redir

      • Igaf on 23/12/2024 - 20:31

        On further investigation I have two main concerns - no mention of cell balancing, and discharge cutoffs appear to be low. The PowMr appears to be a seriously bad/low 2.2V/cell for the 100Ah (a video seemed to confirm that). Werchtay doesn't mention specific voltage cutout.

        • Horacio on 24/12/2024 - 02:59
          +1

          I went and looked at the wattcycle specs, and their BMS is apparently set to 9.2v so that's 2.3v/cell, lower than the usually recommended 2.5v too. I haven't discharged mine till it cut out, I stopped at 100Ah.

        • FLICKIT on 24/12/2024 - 12:11

          I noticed the under and over voltage protection seems on the extreme side of what's considered normal, at first I figured it might be an error in the specs but looking up the JBD BMS used in the 100Ah teardown video it seems that BMS does have those specs:
          https://www.alibaba.com/product-detail/JBD-ZP04S016-4S-12V-l…
          From those specs it appears the balancing doesn't turn on until 14v, which seems high, I might have to bump my normal 14v charging up to 14.2v to ensure it balances… … I'm not too bothered by the protection limits, I don't really push my batteries to the extremes…

          I notice the Ecowatt batteries that are the same size, weight, with similar specs also list the same over and under limits for their JBD BMS:
          https://ecowattenergy.com.au/products/es200
          I assume with those ones having bluetooth there's a good chance you could probably log into the BMS as JBD admin and chance the limits…

          There's a few brands around with the same cases and very similar specs, I do wonder if they all come out of the same factory, just different grade cells and such….

        • FLICKIT on 24/12/2024 - 13:13
          +1

          To add to this.. Just out of interest I looked up the data sheet for the REPT CB56 cells shown in the PowMr 100Ah teardown video, it actually lists the cell Operating voltage range 2.0-3.65V, so I guess that's why the cutoff voltage has been set to 2.2v in the BMS…. Even though it's not ideal I guess they can be dragged that low 'safely', it probably just impacts the life span if it's done regularly…

          It seems they're a 104Ah cell, they capacity test them down to that 2v, a normal operating voltage range would give around the 100Ah I guess…

          I have no idea what cells are in the 200Ah battery, they could be the same as above but who knows, it's the usual gamble with all these low end batteries….

          • Igaf on 24/12/2024 - 16:14
            +1

            @FLICKIT: Unfortunately 2.2V cutoff suggests they don't know what they're doing - or don't care, much like some of the build practices (and some of the programmed BMS settings) regularly exposed by Prowse teardowns. Come with the price I guess. Being aware of limitations like unsuitably low voltage cutouts and no temp regulation (not a huge issue here if you're careful) means you can make adjustments but there's no way around passive cell balancing.

            I've sent mutliple queries to three different eBay sellers about their warranty details. They answer parts of my questions but conveniently ignore the warranty, apart from "X years". As you've said, about the best we can hope for is that the bigger operators are still selling in a few years time.

            • FLICKIT on 25/12/2024 - 16:28

              @Igaf: This is what I find a bit odd, JBD aren't a no-name brand or new to the market, they're one of the better BMS manufacturers that have been around for years, you'd think they'd know what they're doing…. You'd think there must be some logic to the settings they use, god knows…

              I'm not too bothered by warranties, everything from chinese sellers on ebay I pretty much class the warranty as the 6 month Paypal protection period, generally trying to get support from them without that Payapl leverage isn't really worth the trouble… With most these cheaper batteries, if they arrive in one piece, work, provide the rated capacity for a couple of cycles, the odds are they'll be ok for a good couple of years… If the capacity drops off after a couple of years it's unlikely you'd get too far with an attempted warranty claim with the chinese seller or chinese company… I was keen to get a battery with screwed BMS connections and such so if down the track I need to replace the BMS it's going to be a lot easier than dealing with the soldered connections that seem to be in a lot of the cheapest batteries…

  • ocular on 22/12/2024 - 17:36

    The Bluetooth app seems limited in that there is nothing to confirm that it actually reports the voltages of each of the four cells or the difference between the highest and lowest cells. This feature is useful so as to determine how balanced the battery is as each cell voltage approaches 3.4-3.5V But for this price expectations should not be high.

  • Blue89 on 23/12/2024 - 08:29

    Just by the look of the pictures on the eBay site, I would already avoid them! Almost every single picture telling us how great their batterie is and how bad all other brands are. Huge no go, if you don't want to deal with rubbish later on.
