my first build w 32650 LifePO4
#1
Hello.  I am thinking to buy the LifePO4 32650 batteries.  I want to build either 12 or 16 cell bteries to be used with a MPPT solar charge controller to charge another 48v LifePO4 battery (150 watts) away from the power grid.  I live off the grid so have some experience with batteries and charging, but this will be my first LifePO4 battery build.  I have a spot welder that needs fixed.  I don't know where to buy the weldable battery straps.  I am thinking that chinese cells will have a higher failure rate over time?  Is it doable to build a battery where the cells are inserted in a holder with spring loaded contacts for easy replacement?  Or is the resistance to much?   Thanks for any help you can give.

sorry for the duplicate post. My browser got me. I would delete one but don't see how.
