    New DIY 12V Build - low battery voltage from BMS issue

    I bet the capacity tester is putting enough of a load on the BMS to draw the voltage down. A light bulb would do the same thing. Your BMS is behaving the same way as mine did with the older app and the lock was on. I can suggest a few other things to try but they probably won't work. But try...

    CATL 271Ah cell issues.

    You will want to be sure to put insulating spacers between the cells. Don't allow the cells to touch each other because the cell case is positive with leakage voltage.

    New DIY 12V Build - low battery voltage from BMS issue

    Only other thing I can suggest, if you haven't tried, is to reinstall the app. If that doesn't work then your BMS is most likely faulty.

    New DIY 12V Build - low battery voltage from BMS issue

    The "Switch Function" is turned on in my app. Not sure that will make a difference but it's worth a try.

    New DIY 12V Build - low battery voltage from BMS issue

    I have posted twice in this thread, and now three times, the lock you refer to does not exist if using the latest version of the app.

    EVE 280Ah LiFePO4 Review (Dongguan Lightning New Energy Technology)

    If I had to do it all over again I would prefer the laser welded studs over inserting my own grub screws. The threads in the cells terminals are very easy to strip even if using a thread locker as I found out the hard way. Also the recommended torque for the nuts if using grub screws, or if...

    EVE 280Ah and CATL 280Ah For Sale Houston, TX

    Very strange indeed and makes zero sense. You posted the name of your company so everyone knows where your office is. You are posting in the corporate section of the forum and you are allowed to post a link to your website in this section as well as cell prices. If you are legit you are off to...

    EVE 280Ah LiFePO4 Review (Dongguan Lightning New Energy Technology)

    The cycle life is not more than 3500 for the LF280's. :) And to reach 3500 cycles one must use perfect compression throughout the SOC of the cells. Same applies to the LF280K which "claim" a 6000 cycle life. The easiest way to increase cycle life is to keep the cells SOC between the knees. But...

    EVE 280Ah LiFePO4 Review (Dongguan Lightning New Energy Technology)

    Yes but I don't know what the version of the datasheet you have is. It should be at the top of the spec sheet. I have a few data sheets for the LF280's, and data sheets for the LF289L, LF280K and LF280N and I don't see that error. Where did you get that data sheet from?

    New DIY 12V Build - low battery voltage from BMS issue

    The raised material is aluminum. The stud is stainless steel. I believe these laser welded studs have been tested up to 150 amps with little heating at the stud.

    New DIY 12V Build - low battery voltage from BMS issue

    Did you try putting a charge on the battery through the BMS?

    New DIY 12V Build - low battery voltage from BMS issue

    There is no lock mode with the latest version of the android app. Instead there are independent on/off modes on the main screen for charging and discharging and the OP has indicated he sees those settings. So he is not locked out.

    New DIY 12V Build - low battery voltage from BMS issue

    That was on the older app versions. A photo would be helpful to confirm you have everything hooked up directly. :)

    New DIY 12V Build - low battery voltage from BMS issue

    Are you using the latest version of the app that's available from Overkills website? And are you using Android? I had a similar problem when I first assembled my battery and discovered there was a lock/unlock in the app settings. Once I unlocked it the BMS came to life at the output. But I am...

    Scamazon Warehouse - Solar controller shoppers beware

    Today I returned 2 Crucial M.2 SSD's. I bought one and when it didn't work properly I ordered a second one thinking the first one was defective. The bios recognized them properly but with both when I rebooted, I could not even get into the bios until I removed the SSD. So I called Amazon tech...
