New version of Wayne Giles' battery internal resistance tester
The official new ESR/IR Mark II meter thread – NB: READ THE FIRST 10 POSTS - RCG

The meter measures the Effective Series Resistance or “Internal Resistance" of each cell in a LiPo pack. This provides a direct measure of relative cell condition and comparative pack performance. Used in conjunction with a very simple web based “LiPoTool” the meter provides an extremely fast non-destructive indication of the sensible maximum current limit for any model LiPo to preserve its life and avoid overheating. It has brought some sanity to the often outrageous claims of C-rate on the label of some vendor’s packs.

Almost 1900 of these meters are in use worldwide and now…….

There is a new version with the same accuracy and reliability - but much quicker and more convenient to use. It is a development of Wayne’s design by well known RCGroups modeler Rick Distler (rampman) who has been making the original version for some years now. ...
