Nice device to verify internal resistance and other parameters of many types of batteries. I can't speak bout accuracy as I don't have a master reference to compare,but results are coherent with current given and voltage drop when loaded. Model IR502 come with a cloth bag to store and transport it. Well packaged and quickly shipped.
