Low Battery and Arming Buzzer

I use multiple APMs currently, mostly for multi rotor vehicles. I am using them also for a few modified RC vehicles. I know that I can setup a buzzer for arming and low battery warnings with the multi rotor firmware, but I cannot seem to find the option in the parameters for rovers. Is there an option for this?

Much easier to be belt and braces and use one of these

Not at the moment. I use the battery voltage warning in the MP as I am using the 3DR PM to power my APMs.

Thanks Gary. I know I could use an indicator, but I just assumed since the power module monitors battery level and is used under the ArduCopter for the same idea it may be here for ArduRover. Either way it is not a problem. Either I will add my own software to do it or go with the indicator.

When testing with MP, I do use the battery voltage warning, but there are times I just want to go out and drive/test without MP. I am using this in conjunction with Linux and ROS, so I do not use MP very often.
