This is concerning a case of TOPBAND 25ah Lifepo4 New Cells purchased from Battery Hookup.
I'm still waiting for them to respond to my emails.
There is a voltage reading on some cells that the other cells Do Not Have.
I'm assuming one of these behaviors is normal and the other is a failing cell.
The voltages of the cells arrived with typical shipping voltages.
I check the voltage of the cell. Then, I remove the Neg lead from the cell and
place it anywhere on the metal casing of the cell.
Some of the cells show around 0.500v - 0.650v on their case.
While other cells have No voltage reading whatsoever on their case.
Are the cells that have a reading of voltage on their case, Bad?
Or, are the cells with a voltage reading on the casing the good ones?
Are they beginning to Internally Short? Dendrites?
Shouldn't all cells show or not show voltage on their casing?
I purchased these cells to make an E-bike 48v 25ah pack.
Thank you, I really need some advice.
