Bro your best bet is a solid top balance, even if you have to use a genset to do it. haul the batteries down to the closest place with power and the 10 amp charger you bought and pay someone for the power to top balance them properly. if you have your setting wrong they will never balance.
I have had one perfectly balanced pack go out of balance due to setting the balance settings wrong. if the setting are wrong you will slowly lose capacity (not permanently thank god) but what will happen is as the top and bottom get further apart, they will cause the BMS to shutdown to protect the pack. for instance if not in balance, one cell will hit 3.65 and shut off charging...and balance at the same time while one of the cells is at 3.35 (for instance) then with each succeeding cycle the gap will grow and you will get less capacity with each succeeding charge until you cannot charge at all.
TOP BALANCE PROPERLY, reload or update your app, it should show a voltage for each cell or pack. it should show one temperature and only one as you only have one temp sensor for the DALY BMS.
is you have a separate smaller battery pack that you can use, then use it at a reduced level to TOP BALANCE. I cannot say it enough...TOP BALANCE. once you have done that 90% of your issues should be eliminated. anything after that is an APP issue. I have 3 16s packs and on 2P4S pack as my backup power source. the 48 volt packs take care of the house, the 12 volt pack runs my battery heaters, I can use for TOP BALANCING or as an emergency backup (for the essentials) I use the same APP for both 16s and 4S packs this is on an I Phone. until last year I used a android but my phone self destructed and I used a friends old I phone to run things. there were differences in the APPS and I had some issues with the first APP i loaded for the android... I loaded a different app and all was good. I has some minor issues with the apple APP but overall it has worked to date, either will work if you get the correct app.
As always, good luck and keep asking questions, provide lots of photos and as much info as you can.
So I found this in Appendix C of the overkill BMS manual
"If the pack is already assembled in series, and you are unable or unwilling to start over, you can still balance
it with the regulated power supply.
● Connect a charger to the battery with the BMS installed normally. (charger positive to BC[max] and
negative to C-).
● Charge the battery until the BMS reaches a cell overvoltage cutoff.
● Open your Bluetooth app or desktop app and navigate to the individual cell voltages.
● Find the lowest cell and connect your 3.650v regulated to that cell only, in the correct polarity.
● Allow the cell to charge up to 3.650v.
● Repeat this process until every cell is fully charged to 3.650v.
● Now cycle the battery with a load then a charger to verify that the cells are sufficiently balanced.
● If the BMS still reaches a cell overvoltage before the battery is fully charged, repeat this process"
I'm going to try that method
As far as taking the pack somewhere...my closest neighbor is 5mi after that 10mi and town is 30mi away...everyone out here uses a gene and as far as I know I'm the second person to build a lifepo4 pack.... I also don't want to tear down the pack as I've noticed my positive terminal on my last cell is stripped but still tight so if I remove it I'll have to fix the threads.... ?
As for the Daly app I was using the most recent one offered in the posts here as well as the PC software. The JBD/overkill is working though
