AUDIOROOT eHRS4-HSW-4W

With this cable, you can connect 2 AUDIOROOT eSMART batteries to BG-DU or BG-DU-REG for simultaneous use or replacement during operation. As this cable is passive, BG-DU will only display battery telemetry from 1 battery when 2 batteries are connected. The battery from which battery information is read is selected randomly (the first battery to respond to smbus master commands). Always the battery with the highest voltage supports the load. As the battery voltage is self-balancing during use, they will tend to share the load 50/50. At this point, the current and power information displayed on the BG-DU will be half of the actual values and the estimated running time will be correct.
