  • Post in thread: Preventing 32 EVE batteries from moving...

    Hello, I just received my batteries in the mail and now I need to find a way to secure them in the basement of my 40ft bus. I am going to be making a 48V battery bank out of the 32 cells so I need to be able to connect them all together either with bus bars or cable and then making a frame to...
  • Post in thread: Canadian Import fees ?

    Where in QC? How many are you planning on ordering? I'm going to be ordering 30-40 of them want to do a group order? I'm working with my supplier over there to see if we can get a price from the factory. He sources all my products and is very reliable. Let me know what you think. Im near MTL

    maybe, I run the AC all day long. I didn't think it would do that though. Nothing different than the other days.
  • Post in thread: 3600w solar system only getting 2000w??

    Hello, I have a 48v system with EVE batteries, 32 of them, and 9 400w panels on the roof of my converted bus. I run a Victron Mppt, Victron Quatro, Victron Cerbo GX and a REC Q1 bms. Recently the solar system started only sending 2098w max to my battery. I just cleaned the panels with no...
  • Post in thread: Battery not balancing well.

    Ok, so that sucks. I did just let them sit without a charge. When I did that I didn't have any way of charging them because I was at an off-grid cabin with a very small solar system and my bus conversion solar system was not set up. What do you recommend that I do from here on?
  • Post in thread: Opinions on how I'm connecting these 32 * LFP 280Ah cells (16S2P)

    Hello, do you have a finished product photo of your battery bank. I am planning on building the exact same set up on shelves as well. Thank you
  • Post in thread: 3600w solar system only getting 2000w??

    It doesn't matter because when I turn everything off it doesn't give me any more power from the panels. It is the same when there are loads and when there are no loads. But the AC load is usually around 700-1000w while charging. I used to get around 1400-1800w of charge while running my AC.
  • Post in thread: About to order my battery bank. Got a question

    So this is a good deal? Or should I just go with the bulk ones and save a bunch of money? Also, would you recommend buying one or two more cells to use as a swap if one of the cells in the bank is off?
  • Post in thread: Fuse Sizing

    Ok so I have a Quattro 48v 5000w inverter. So you are suggesting that I would need a 730amp fuse? Is this the Class T fuse that you are mentioning adding right by the battery? yes, that's what I have. I was thinking of putting it before my contactor actually and then putting the fuse on the...
  • Post in thread: WHOA! That was weird, Need some help plz

    it's a DIY Lifepo4 pack. 2p16s, 32 cells. Tomorrow I am taking the battery apart, if I can't get another solution tonight. It's going to be hell to top balance them as I am off-grid and running on solar. haha good times are ahead. Please let me know your solution.
  • Post in thread: WHOA! That was weird, Need some help plz

    Yes, that is true but then it gets balanced back down with the pack. If I set my max at the same as the end of the balance then I would have the issue as well but it would be above the max that the cell is rated for.
  • Post in thread: WHOA! That was weird, Need some help plz

    Hello, I have been running a LiFePo4 48v 2p16s battery for the last two years and two days ago it dropped off a cliff. Now when I try to charge it back up it keeps on hitting the max voltage for my settings and stops charging. I have attached screenshots of everything I have, I lost my logs...
  • Post in thread: Cabin 24v battery system. It gets cold!

    Hello, I am building a battery bank at our cabin in Canada. It is a summer cabin and the batteries will be left here during the winter months, it gets to -20c(-4f) in the basement in the winter where the batteries will be. It's a family cabin so not everyone is DIY capable/comfortable. I have...
  • Post in thread: Battery not balancing well.

    Hi, I'm not sure what is going on with my battery/BMS. I have a 32 cell pack, EVE 3.2 280ah, with a REC Q1 BMS. When the battery is drained past about 60% SOC the next day as the pack is charged back up everything is great, the cells charge at an even rate and the BMS doesn't need to work at...
  • Post in thread: WHOA! That was weird, Need some help plz

    No, I have never had them the exact same. The battery doesn't go that high. Should they be the same?
  • Post in thread: About to order my battery bank. Got a question

    I'm not sure if it is worth it. This is the first battery that I have ever built and I have never set up an off-grid tiny home before. I'm still learning but I can see that this is worth getting over the battle-born batteries or the Nissan Leaf batteries.
  • Post in thread: Battery not balancing well.

    After changing the balancing settings the battery balanced much better but the other day things didn't charge up as they usually do. I cleaned my panels and it started charging better but as you can see on the last few days the cells didn't balance well. Do you have any suggestions on why this...
  • Post in thread: Fuse Sizing

    Thanks for clarifying that. I was planning on a 300amp fuse but maybe I'll look for a 200-250amp fuse. I will put the fuse right off the bus bar and connect it to the wire going to the switch. If the fuse blows then I will not be able to shut off the power when replacing it though. This was my...
  • Post in thread: 24kw-30kw Off-Grid System Build

    Hey, thanks for the reply. This is actually going to be a vehicle-mounted system. It is a school bus that I am going to be traveling with. I plan on spending 2 full years in it traveling through the southern USA, Mexico, and up into Canada during the summer months only. My mistake on the...
  • Post in thread: Battery not balancing well.

    Thank you. I have finally got a log going so that I am able to track the cells charge speeds. So once I have a week or two of data I will check to see if it is the same cells every time. I'll let you know. Once I have that data I will be able to swap cells to make the pack better.
  • Post in thread: About to order my battery bank. Got a question

    So the ones that I was quoted are the New Version EVE Genuine Grade A batteries. not sure what the difference is between the two. I would save $1000 if I went with the 90$ battery. How did you connect your 36 cells?
  • Post in thread: Battery not balancing well.

    Ok, I will look for one. I am currently in Mexico so I will have to find one at a big city. Can you please explain this a bit more, I don't completely understand what you mean. Thanks
  • Post in thread: 3600w solar system only getting 2000w??

    I see what you are saying but in the past, I have had no problem charging up. It also used to show the amount of power coming in regardless of the load and that is not increasing above 2098w. I used to have 2800+w during the middle of the day.
  • Post in thread: 3600w solar system only getting 2000w??

    I do not have any fuses on the roof for this reason. I have all panels plugged into a busbar stud on the roof. I will climb up when I get a latter to check but the wire coming down to the MPPT is fine and showing the same voltage as the Cerbo. I will look for a DC clamp meter it's a good idea.
  • Post in thread: REC Q1 BMS Balancing Question. 2s16p LifePO4 pack

    Hello, I have a 32 cell pack, 2s16p at 48V and the BMS is heating up at every charge. It gets up to about 53c while it tries to balance the cells. I have attached screenshots of the settings I have set in the BMS, do you think that the settings are causing the issue? Sometimes the pack...
  • Post in thread: Fuse Sizing

    I have a material called Puck Board. I used to use it for practicing stick handling. It's the type of material they use on the side of hockey rink boards. You can rub the crap out of it and it hardly damages it. I am going to put this in between each cell and on the outside edge as well. I have...
  • Post in thread: 3600w solar system only getting 2000w??

    I did change the absorption and float voltages but not that much, it doesn't even get to the absorption max voltage. On the MPPT it says bulk most of the day. My Max charge current is set to 70 or 100amps and my panels are only 9.69amp panels and they are in 3p
