AudioRoot eHRS4-HSW-4p

This cable can be used to connect 2 x AUDIOROOT eSMART batteries on a BG-DU or BG-DU-REG for simultaneous use or hotswapping.

Important notes:

• As this cable is passive, the BG-DU will display battery telemetry from only 1 battery when 2 batteries are connected. The battery from which battery info is read is selected randomly (first battery to respond to smbus master commands).
• It is always the battery with the highest voltage which handles the load. As the batteries’ voltage balance themselves during use, they will tend to share the load 50/50.
• At that point, current and power information shown on the BG-DU will correspond to half the actual values, and estimated runtime will be correct.
