Please disregard above. Jim, AJ8S, has suggested a product that my resolve my quandary.
A very good way to reduce risk is to limit the current available to the rig, I use a buck converter set to 12 volts out and with current limiting set to 0.7 amps. I use this one: For those of you running on batteries this device will also keep the voltage going to the rig at 12 volts even when the battery droops lower than that.
..if I am all wet of this, advice appreciated.
