Features and Benefits Procedure ModelGauge m5 Algorithm The EV kits are fully assembled and tested. Follow the Monitors from 2S+ Cell Packs steps below to install the EV kit software, make required Battery Pack Input Voltage Range of +4.6V to +39.2V hardware connections, and start operation of the kits. The Thermistor Measurement Network EV kit software can be run without hardware attached. It automatically locates the hardware when connections are Optional On-Board PCB Trace Sense Resistor made. Note that after communication is established, the Windows 7 or Newer Compatible Software IC must still be configured correctly for the fuel gauge to Proven PCB Layout be accurate.
