Just to clarify if you are ever wondering on IR. IR is like proportional to the capacity of a battery of the same chemistry. So a 6000 mAh shorty will show a much better lower reading than the 4600's.


The best tool and I know you are going to buy it is the ESR meter available at Progressive RC. This is the standard and anyone else with this tool will be able to report their findings and we can all see and not worry on how each charger is calculating this. You can measure at Storage Voltage around 22 to 25C temp and charged up if you like.
