I'm using a overkill bms on my 280ah lifepo4 batteries. It was working fine in my system. I took the battery apart to top balance these new cells using CV cc device. Charged them up and then reassembled into pack with bms. Hooked it back up into my system but now with the slightest load it shuts down discharging. I was able to keep it on with a 2 watt led light but anything more shuts it off. I do the reset option in the software it allows discharging and when I turn on anything it shuts it back down. The BMs is still showing cells are at 3.41 or so, pack voltage is 13.7. Before I top balanced I was able to run a heat gun at 1300 watts. What did I do? Thanks
