I am planning on a new 18650 triangle battery build using samsung 15q 18650 cells ,its going to be a 13s 8p,i see repakir to match the cells capacity but no mention of the cells internal resistance,im testing all the cells using a litokala engineer lii-500,some of the cells read 30 milliohm ir and some 125,how should i arrange them regarding internal resistance to keep them ballanced,i have a bt smart bms but want to do the best i can to match them for ballance,cheers in advance.
