Very nice well done.

I noticed that you have a lot of Sony US18650GR ** cells in pack 2 and 3 . At least that is what they look like.
Please be cautious with those cells as they have a tendency to be high in IR and can cause pack imbalance.

Hi. thank you for this warning. 

for the moment cells are not correctly dispatched. 
finally i have decided to make a 14S120P battery. 
Because of you intervention i've read discussions around this type of cell. 
when i'll mount the battery i'll be carefull. 

Tongue  May the Power go to the wall  Tongue

Best regards.

And I want to thank you as your Videos on Pack 5 pushed me to do it exact cell tested number.   Takes a bit of time to find them all but it's not too bad.    

When I capacity test each pack I am within 1Ah of each other.   and that's 4.2 - 3V   I run my Wall 3.5 - 4.1
