Yep I re emailed them. 100% the BMS as I switched them from my other battery pack that has no issues(should have done that first) The problem followed the BMS and it was throwing numbers all over on the other battery pack. Thanks everyone for chiming in.

Well it doesn’t seem to be the crimp. Recrimped 3 times using a ratch and a simple cline crimper For whatever reason that cell #8 once it hits 3.45 the bms starts shorting out almost like it’s hit an over volt and shutting it off. Once it gets to 3.42 or so it kicks back on. Works fine charging...

I think I just need a better crimper. I have an i crimp which is like the wire fly I believe. I wasn’t trying to skimp on the tool just didn’t know which to choose. Or maybe go with metal leads and add the heat shrink rather than already has the heat shrink.I did notice the #8 was the issue I...

Agreed

And of course once I fully remove the battery and put on a work bench it starts reading

That was from the cell #8. Full pack from cell#1 terminal to #8 connector pin reads 27.44

Yep it 3.440 at the connector so traveling the lead line to the bms

And to clarify I have top balanced so I don’t think there was an actual cell over volt. I think the one cell reading dropped and it caused the readings to go haywire.

I also just tested at the negative cell terminal and the bms connector pin and got 3.440 so it is traveling to the bms

I disconnected the bms lead connector from the bms and tested voltage from the cells teminals

Anyone know what would cause this? The batteries have been running fine since January. I did have something similar in January but it was a loose crimp on a wire. Once I recrimped it was fine. I removed #7 and #8 lead and tested continuity from the lead to the pin connector and both were fine...

Don't know if people saw but all of Shenzhen got shut down for the week for Covid. I don't know how many more things can jump in the way for me. It's comical at this point. Just rolling with it.

@John_B don’t leave comments here if you don’t want to contribute. We all are open minded about individual results and truly want to understand if there is a problem. If there is then we can either all work together to fix it or let everyone make there own educated decisions on how to move...

Thanks for trying Just John. People be people. :poop:

Didn't take it aimed at anyone. I agree that the system is seriously F'ed right now and that has nothing to do with the suppliers or the shippers. I would say it's not the consumer's job to ask for a better shipper, always. If someone says to me it will come by FedEx I would assume that's pretty...
