      At 1:43 I think you made a bad assumption. Just because they are all connected there is NO guarantee that they are at the same state of charge. Unless each of them was TOP Balanced together you may be getting batteries from different batches with different SOC's ... We had a server pack at work not pass their UPS Emergency run time and it turned out that one of the batteries was way out of spec from the others and therefore shutting down the charging way before any others. Let me know if I am not thinking straight ...

    Excellent video Will! I’ve run the numbers several times on those battery packs trying to come up with a more cost effective solution versus buying server rack batteries but by the time you add the bms the savings just aren’t there. This is especially true if you start to take into account the features like built-in breakers, communication ports for the BMS, etc. In this video you implied that there may be a way to build a large battery bank using fewer BMS‘s. Obviously that would help make the whole thing more cost effective. I would love to see a video or hear your thoughts on a big DIY build that might compete with the 30 kWh a full server rack from EG4 give you.

      @@ncsojourner200 Hey Rusty, I'm on mainly using it for Emergency Backup power. A couple years ago we had a Snow Storm and were without power for 3 days. I have 2 Gasoline powered Generators but if you can't get gas the generator won't do you any good. This system can supply 20amps of 110V so it can power anything you want up to that 20 amp limit. It could power a Small AC unit, Space Heater, and pretty much everything you have on your list. The reason I went with 24V instead of 48V was to keep the cost down. I spent the extra money on the Solar Panels to get the battery charge back up with limited sunshine. Thats it for now.

"If you need help I will help you, If you screw up I will help you, if you kill it I will refund your money , send me back the dead BMS" LOL you can't go wrong. The only thing I will do is use SS set screws and bottom them out at 15 inch pounds. That way when tightening the nuts down I can hold the stud made by the set screw still. That way there is not chance of stripping the threads. Shipping of the BMS was very fast.

    I got some of the "extra" smoke out of a BMS when I plugged the balance connector in without ensuring that each balance lead was wired according to the diagram. The easiest way to make sure that it is correctly wired -- before plugging the balance connector into the BMS -- is with the multimeter negative lead on the black wire connection and then touch each white wire with the positive multimeter lead -- in order -- and the voltage should step up at each white wire .... 3.6v, 7.2v, 10.8v, etc. I got lucky since they had programmed extra smoke in the BMS and it did no harm -- the first time.

    Just to let everyone know. Everyone is shipping fast. I ordered the battery on April 14th 2022 and it arrived on the 19th. It did not have the hardware packed with it, but it doesn't matter I will be using studs instead bolts anyway. I ordered the BMS on April 14th and it arrived on April 18th 2022. I paid the extra $10 to have the lugs crimped on and would recommend it to all. BTW due to my dual use of this pack I need it as a small lightweight (somewhat) pack some of the time but plan on adding another battery bank when I'm out in the middle of no where and can't set out solar. At that time I'm going to have to decide whether to switch between batteries or ( I know I know ) run them in parallel. This pack was just too well put together for me to pass it up. It fit my needs very well. Thanks for the heads up and tutorial.

      No.. However the BMS can monitor the wattage use for you. I added it to my solar bank and so far it charges and discharges as advertised!! The cells are also at perfect balance. One thing i learned in using cells and this BMS is that the leads from the BMS MUST be very secure. The slightest loose or frayed connecting will result in a "false" voltage reading and will cause the BMS to go off on alarm!!

    Hello from Sacramento CA. I was cruising your channel last night expecting a new video and missed it and I am scribed??? Will definitely be looking into this. Just about done with the water damage/seal of my 1970 airstream remodeling. We are putting the bedroom in the back and the bathroom in the middle. Not sure of the position of the bed. So were taking it out this week to decide if we like the current mockup. This will decide how and were the batteries will go in the trailer. I plan on putting in floor lockers for the batteries and that footprint will change depending on the placement of the bed. And the more low slung weight closer to the axels the better. This is a major systems upgrade and 5years of planning on two different floorplans to even out weight distribution I have already taken out over 60 feet of copper pipe. I am planning on loadsharing the trailer and the boat with the houses electrical grid. I mean why have them sit idle. My goal is to be grid free but have the option to reconnect to the main power grid when and if we move. Great job Will quick and to the point.

      Yes indeed but that other spot doesn't crimp that well. I only use the uninsulated spot. the insulated one is too close to the cutters and I've messed them up using them like that

    • @glenndennis6801
      @glenndennis6801 2 роки тому

      Yeah have to agree, need proper crimpers. Crimps are not done the best here, really amateurish. Which is too bad because the info here is great.
      Not sure of the gauge of balance conductors but looks from video to be smaller than 14 - 16 AWG, (Blue) terminal, maybe need 18 - 22 AWG (Red) terminals.
      I find when instructing people on how to do something, do your best and if some a little sloppy at first, at least they were shown the correct method.

    DO you have a tutorial for a 12V DIY from scratch?
    I would like to build my own 12V LiFe batteries and I have a very very VERY tight budget, but my flooded batteries can't take our needs and I am draining them.
    Thank you! Your videos are incredible!!

      Did you build your 12v system? Care to share which brand of products you purchased? (Battery,charge controller, solar panels, inverter) There are so many brands now, it's hard to tell cheap junk from budget friendly goid!

    I was surprised that a crimp connection is better than solder. Can you explain? Is it because solder can crack? Thanks.

    I'm currently building 4 48v batteries from 8 of these battery packs. I purchased the 48v version of the bms you used in this video from overkill solar. It all seems quite straight forward except for 1 thing. The wiring diagram that came with the bms clearly shows the BC0 lead connecting to the main negative, then BC1 connecting to the 1st cell positive, then BC2 connecting to the 2nd cell positive, then BC3 and BC4 connecting to 4th cell negative and positive. Then BC5 and BC6 connecting to cell 6 negative and positive, BC7 and 8 connecting to cell 8 negative and positive. It continues like that, skipping every other cell and connecting to negative and positive. The wiring diagram you show for the bms you have shows the same, but you wire every balance lead to the positive of every cell, just like every other bms video I've watched. So, which way should it be, the way the diagram shows or the way you did it?

    Hi and thank you for your awesome videos. I been wanting to build my own battery and I found this video. I have a all in one 24v 3kw inverter that clearly says for seal, agm, and lithium battery only. I was wondering if a 24v lifepo4 with a BMS like the one you are building on this video will work with my inverter? The battery connector on my inverter is only one connector so is has charge and discharge function. Thank you.

  • @BlkFireHawk427

    Just got mine this week took a little over 14 days to receive it and it was damaged. The box looks fine but the cell on the pos end is pushed up and the buss bar is in a bind. I have emailed them today and hopefully will hear back soon. I am worried if I tried to pust it back down it would damage the cell or bust the welds. Was really looking forward to assembling this today.

    If the bolts are too long, you can either file or cut them to make them shorter vs hacking by adding washers or adding a nut :)

    Question-
    Hey Will
    I love the depth of information you provide and the way you explain the info .
    My question for you is if I'm wanting to make a solar set up that is going in my work trailer wanting it to be able charge all batteries for cordless tool the biggest batteries i have are the milwaukee 12amp ones , but I also like to be able run my table saw and chop saws and all corded tools from this and if the ever blackout I like to be able run extention from trailer to the standing freezer and chest freezer and fridge and be able to run these continuously, if have sun every second day to top batteries back up . Was hoping to be able to do this for under 3-4 thousand dollars.
    I sore that you said those 250w panels that $60 where good also I have a 3000 w inverter already , but if you can't let me know if what I'm trying to do is even possible?
    Thanks heaps for your help on this will

    I would like to know if you can make a recommendation for batteries for a marine application. I have twin diesels and 3 batteries. I need them to be able to crank the motors and then run the electronics. I’m more concerned with practicality and safety as well as cost. Not going to have a completely solar setup, but may expand to that in the future.
