The Blue View Battery Management System gives you visibility to how your battery system is doing. A simple, graphic interface shows amps, volts and capacity remaining. It also has the capacity to look at each cell voltage and temperature individually. Alarm outputs for over/under voltage, over temperature and over current are also provided. The video output is compatible with most monitors and DVD players. $300 for the computer and $15 per pod that monitors a battery cell. Up to 256 cells may be monitored. Wiring is a snap, only four wires are required for the pods, no matter how many are used!
