The LEM HASS and the Honeywell CSLA families may work better in these applications. They slip over the battery cable so it is not necessary to cut the battery cable. They are also isolated from the conductor. Lastly, the power and signal connections are made using a standard MOLEX-type connector so it is more servieable than the PCB mount types. The two I have linked to use single supplies (+5V for the LEM and +8~+16V for the Honeywell) and are not a lot more money. If you are using the Honeywell part, you may have to use a couple of resistors to divide the output voltage down to make it suitable for the Analogue input on your C-Rio.
