  • Post in thread: Daly BMS (250A 4s 12V) reading wrong cell voltage for first cell

    Well I have taken a look at my batteries today and the cells are all within 1Mv of each other. I have just let them sit for the past couple of weeks with without any charging or discharging. As I said, I had a significant difference with one cell but never tested that cell with a meter to see...

    Put the correct size screw driver in. Hold firmly and give a good solid hit with a hammer.
  • Post in thread: Buying from AliExpress within the EU

    Welcome Brian, There are many on Ali express that will take your money and sell you duds and a few on Alibaba that will do the same. Probably the best thing to do is find the name of the seller and do a search on here to see if anyone has left positive reviews. Take a look at Amy Wan from...
  • Post in thread: Which MPPT/PWM controller between sun panel and LiFePO4 battery?

    I use an EPEver Triron and I have no issues with it. Buy the Bluetooth module to go with it and set the App up on your phone and you can see all the data you require.
  • Post in thread: BMS help

    I have an EPEver Triron and dont have the documentation with me nor can I remember the settings i used but they will be the same as listed below. On page 24 of the link below are the LifePO4 settings that you can use but double them as you are now using a 24v system...
  • Post in thread: BMS help

    I did see that you were also asking about compression somewhere but couldn’t reply to you. There are those for compression and those that can’t be bothered. I actually compressed mine at first then just simply clamped them up and taped them together before removing the clamps. At between 3000...
  • Post in thread: Safety tips for me (newbie)

    Great to hear that you managed to succeed. :)
  • Post in thread: BMS help

    Set your charged setting on the Shunt to 14.6v. Set absorb to 28.8v Set Float to 27.6v Put some serious current draw on your system like a 1000w heater, 3amps at 24v is just a trickle. You seem to be overthinking the role of the BMS and what it actually does. It does not make the decision of...
  • Post in thread: DIY solar battery storage

    Hi Wattmatters, yeah i been reading lots of your posts and you have built a beautiful system :). Have you looked at connecting into the grid or aren’t you allowed? I purchased cells from China for my caravan so have 560Ah@12v, but have an itch to buy some more :unsure:. That of course means...
  • Post in thread: Battery Lost Power too quickly

    Your 100Ah battery has approximately 50Ah capacity so if your inverter remained switched on and as Mike says uses 1.5A per hour then in 24 hours that is 36Ah. That is what you need to replace each day plus any additional power you use. Although your panel can produce 16A under ideal conditions...
  • Post in thread: EG4 batteries screw issue.

    As I said…put the best fitting screw driver in and give it a good bang with a hammer. It is the same principle as removing the retaining screw on a vehicle brake drum. But take a look at your screw driver ends to make sure that they aren’t chewed up. Looking at the bottom screw it is chewed up...
  • Post in thread: Inverter beeping

    Looks like you have another bad product. I can only suggest you send it back and get a refund as the reviews for that inverter are horrid.
  • Post in thread: Help with MPPT settings

    You are 100% correct lol. You and i knew what I meant but we have to express it in every little detail for those that don‘t.
  • Post in thread: BMS help

    No you need to monitor each cell. The last thing you want to do is try and take shortcuts.
  • Post in thread: Battery Weight over Floor joists

    I could do the calculations for you but straight out you are talking about the weight of two adults and structurally your floor most certainly can take that. Without even looking at the stress grade of your floor joists at a 10 ft span they wouldn’t even have any spring in them let alone be...
  • Post in thread: My negative experience with my solar charger Epever Tracer10415AN and a warning for using it with Lithium Battery

    The manual I showed you also does not have a dedicated setting for lithium batteries, this is because there are numerous types of lithium batteries which require different charge rates. Instead you have to choose the user setting and nominate the values listed under the correct lithium type...
  • Post in thread: Some corrosion on one of my new cells vent, should be ok?

    To me it looks like some of the liquid has condensed under the seal or that there was a small amount there that has since evaporated.
  • Post in thread: Low Cost Chinese inverter doing its wonders

    Ok you have mixed things up a little between an inverter and a solar controller I believe your question relates to the solar controller. The link you supplied doesn‘t go to the product you are referencing. Untill we can see the specifications for the controller we are unable to advise you...
  • Post in thread: Daly BMS incorrect current polarity.

    Just did a quick check whilst the rain has stopped and no the reset did not correct the negative display issue. Will wait for the software update if ever they release one but I have always known that it was working.
  • Post in thread: Just a total noob building a 8S JBD BMS from Amy Wan

    Yes, but you still connecting to the positives even in the middle of the busbars. Think about which way the current to the BMS runs irrespective of whether your + of one cell is connected to the - of the next cell. Just remember to take your busbars off to drill them as we don't want to see...
  • Post in thread: My negative experience with my solar charger Epever Tracer10415AN and a warning for using it with Lithium Battery

    Lithium batteries do not require equalisation but under the user profile it is unable to be turned off so it is set to 14.6 or lower so it becomes like part of the absorption cycle. At the bottom set absorption time to 0 mins. Tim
  • Post in thread: Seplos 200Ah BMS

    Not sure but this may help you.
  • Post in thread: What's the point?

    Ha Ha Stuart I’m an ex Alway boy living in now, sunny at the moment Australia :cool:. You don’t need aircon there but I’m coming over in August so get rid of them clouds.
  • Post in thread: 2 mppt controllers compatibility

    I do it and many others do it. It is not a problem as long as you set the parameters the same on each controller. You may get one controller shut off before the other but your battery will be very near fully charged.
  • Post in thread: Hello from sunny England

    So on a rough calculation your feedback to the grid would almost cover the daily standing charge. Therefore you only have to consider the amount of electricity you will consume from the grid and whether it is cost effective as opposed to the cost of buying batteries. In my case it clearly isn’t.
  • Post in thread: My solar panels are not fully charging, Low power on Epever Tracer4215BN 430 W solar / 280Ah LifePO4

    Ok firstly that one cell is way over and showing 3.951v. You need to discharge that cell quickly or you will destroy it If you haven’t already. Unless you have a means of discharging the one cell then you need to discharge your battery and get that cell below 3.65v. Looking back through your...
  • Post in thread: Mixing different solar panels

    My understanding is it is all about efficiency in that if you use lower voltage panels with higher voltage panels then the lower voltage panels will drag down the voltage of the higher panels. Some people will do all they can to obtain the highest efficiency possible and other will accept a...
  • Post in thread: Controller help please!

    In relation to your solar panels the type of battery does not matter. Your controller matters in relation to the type of batteries and the voltage. If your Rich solar controller is the one in the link below then yes you can use that instead of the Colman controller. Connect the controller to...
  • Post in thread: Will my panel be to much for my battery ?

    Just buy a mini controller as long as your battery isn’t Lithium. It is exactly what I have for my boat. Just leave and forget. Mini solar controller Just don't buy from Australia lol.
  • Post in thread: Daly bms wont stay on

    My pleasure, just keep in touch to let me know how it works out.
  • Post in thread: My solar panels are not fully charging, Low power on Epever Tracer4215BN 430 W solar / 280Ah LifePO4

    Hi again Missoo. Firstly stop worrying about the SOC shown on the BMS for the moment and lets get your battery sorted. Even if the SOC is showing 50% when it is at 95% the BMS isn’t going to use the SOC to regulate the maximum level of discharge as it uses voltage to do that. Here are a link...
  • Post in thread: Help with fuse size for inverter?

    Don’t even think about buying it! Everything about the advert is wrong so buyer beware. Firstly as pointed out it says 4000W when it isn’t. The inverter is nowhere near the size a 4000W inverter needs to be. the cables shown to the inverter are nowhere near the size required for 4000W. The...
  • Post in thread: Choosing the right ring terminal

    Have you thought about putting a little solder in to fill up any gaps?
  • Post in thread: I accidently deep discharged my LiFePo4 prismatic cells

    No need to apologise as it seems like you have enough on your plate. Hope it all works out for you. I need to do some tests on the Daly BMS to see how much they drain the batteries and why they didn’t shut down when reaching low voltage. At 0.2A it will take forever on yours. As mine are...
  • Post in thread: Hi from Brisbane, Australia

    HI Peter, welcome. I’m actually up at Bulimba at the moment, live at Corlette, Port Stephens and on my way to Port Douglas. I have built two 280Ah batteries each with a Daly BMS and have no issues For my caravan. There are recommendations of where to buy cells from on this forum but more than...
  • Post in thread: G'day guys

    At that price I wouldn't mind knowing which supplier if you would care to share.
  • Post in thread: Using Tape to Compress LifePo4 Cells

    Agreed, except I stole some of the poly chopping boards from the kitchen which my wife is still looking for :ROFLMAO:. The blue, green, red, yellow and white also add some colour and the board handles make great handles for my caravan batteries.

    Hi Matz, Welcome, I’m from Corlette, Port Stephens. Hope you get addicted :ROFLMAO:
  • Post in thread: Problem with a lithium battery

    When you said you were looking at VoltX batteries and I saw your nic then I had a guess that you were. I think VoltX are only in Australia. I’m at Nelson Bay NSW. Glad to see you got your battery going :).
  • Post in thread: Hello from sunny England

    Welcome, I have just had a 9.9kW system installed with an 8.3Kw inverter, but I’m in sunny (supposed to be) Australia. Back visiting the UK in August. First thing to consider is when you actually use the majority of your electricity because if you can use most of your electricity in daylight...
  • Post in thread: My solar panels are not fully charging, Low power on Epever Tracer4215BN 430 W solar / 280Ah LifePO4

    Settings seem ok but I have my differential set at 0.02v. If your were charging when you posted that photo then why is the BMS allowing the battery to be charged if you have a differential of 0.074. You have indicated the balancing to commence at 3.4v but what are your cell settings to turn...
  • Post in thread: Safety tips for me (newbie)

    The last post alerted me back to this topic and just wondered how you went Maggie? Tim
  • Post in thread: Door to door sales people

    Yes ther are plenty of incentives to install solar here. I’m on a one year contract so I am able to change utility companies if I want to after that. Some of the companies offer plans to install solar for you but then you are tied to them for about 7 years.
  • Post in thread: Battery Lost Power too quickly

    Great to hear :) A great warning but i think you will find that he means 10AWG from his solar panel to his controller ;)
  • Post in thread: Smart BMS App settings...?

    The SOC is not an accurate measure of the actual state of charge. I have two real Daly BMS’s and mine are out significantly even though the voltages on each battery are the same. I can actually set the SOC on mine to whatever I like but really 1.3% difference in the SOC is nothing to worry...
  • Post in thread: Which CC for small home-made LiFePo4 camping battery?

    Consider that solar blankets laid flat will produce about 50% of the rated power. Even tilted then you will struggle to get 80%. Will take a look at the Victron for you.
  • Post in thread: diy off-grid regulation in Australia

    Just came across this thread. Australian Standards are not laws and are only enforceable when called up by legislation. In other words there has to be Acts or Regulations under Federal or State legislation that call them up then they become referenced documents and they can then be...
  • Post in thread: Hello from the UK

    Welcome Louise, Sorry to hear about your long term Covid and I wish you a speedy recovery. What part of the UK are you? I’m originally from Newport South Wales. Winter will be hard for you especially with little sun so firstly you may wish to consider a backup power source like a generator...
  • Post in thread: Charge controller

    Ok what you first need to look at is your power consumption as you want to run your fridge all week. Is it a 3 way fridge? What is the power consumption on 12v? i think it will be way more than your battery is capable of providing. it would be more economical to run it on gas.
