Would it be possible for someone to post a step by step method to measure IR on each cell?

Assuming you don't aready own a charger that measures it and that you do own a multimeter.

If i read correctly the procedure is ;;

measure voltage across cell.

Apply small load and remeasure voltage under load, as well as measuring current.

What I need is the formula for calculate IR from Open Circuit Voltage (OCV) and the Load Voltage (LV) and Load Current (LC)

Is it (OCV-LV)*LC= IR...?
