This is my review of the ZK-J30 Coulometer sent in by icstation. Its a little module that hangs between a battery and a charger / load and keeps track of the power that goes in and out of the battery. This explains why there isn't much action in this video, charging or discharging batteries for hours isn't exactly exiting, you have been warned. The ZK-J30 gets its own power from the battery (or charger) it measures. If you want a "pure" measurement, the I show an easy modification to the module that allows that as an option.
