Hello

Hope you are all doing well. Im new to the group and have a few questions

I want to build a 15kw powerwall with 18650 with harvested cells.

So far I am running into cells with 50%, 75%,100% capacity and various resistance.

The question is can I combined various capacities and internal resistance. I want to use cells of more than 1500mah and less that 250 of IR. I am checking if they heat during the charge and dischage with the Zanflace c4.

Would it work?

Thanks

Also find the cell testing flow charts, they may help your testing process & weed out bad cells early.
