acceptable bottom balance voltage delta

I'm discharging my 280ah LiFePO4 cells from Xuba to bottom balance them. What is an acceptable delta in the cell voltage? Right now they are about 0.074 vdc between max to min (3.141 max, 3.067 min). Thoughts?

Personally, anything inside of .05V UNDER LOAD is acceptable to me. .03 is better.

For bottom balancing itself, they should be within <.01, or you can't say they're balanced. Best achieved by wiring in parallel and discharging all cells in the same operation.

If you find that you do not have well matched cells, top balancing is the better option.
