Battery Voltage Recorder BVR20 is a portable, handheld device primarily intended for measuring battery voltages and temperature while battery is either connected or disconnected from the network. BVR20 can also provide data on the density of electrolyte by communicating with an external Density Meter (DMA35) over an infrared (IR) link. An additional feature is the cell tags readings enabled by cell recognition over Radio Frequency Identification (RFID).
