Please look up why there are gaps on the nickel strips (over each cell). Those gaps serve a purpose, that you are not using correctly. Also, always check the voltage on cells that you are wiring in parallel. Don’t assume that new cells will all be charged to the same voltage when you receive them. Another issue: when connecting the BMS board, you should start with B-(ground), then B1 (4.2V), then B2 (8.4V), then B+(12.6V). Wow, the battery terminals are in danger of shorting out your cells. Perhaps some kapton tape or an insulator to prevent this? The charger you are using is only 0.5 Amps. At that rate, each cell in the 7P parallel arrangement will only see about 70mA. For a 2500mAh cell, that would take 35 hours to charge.
042723/0543h PST 🇺🇸 TEST-1 Thank you for pointing out the flaws in the assembly. I was like aghast when the spot welding was performed, quite unusually. Also, it’d have been quite appropriate if an insulating sheet was spread at the bottom of the cell array and specially on the top. When the lid with both terminals were being placed, I was in shock. Aw well…
Yes, i was doing it no problem. I am courius is this possible to connect in series to get higher voltage but i am not sure and i dont want to damage the bmss
