For remote applications, you can manage the battery pack by the BCC. In this scenario the BCC needs a separate power supply, together with the power supply for the remote-control hardware (GSM modem, etc.)
By means of the BCC you can shut down the operation of the battery pack remotely and you can restart the operation remotely as well.
Again be sure to contact GWL/Team for a paid assistance for the complete design of the solution and the detailed analysis of the operation. (approx 3 hrs of support time)
