Quote, originally posted by Jeremy96gase »I smell snake oil. I believe you're right. The alternator produces about 14VDC and while battery is charging, the voltage across its terminals rises and current drops to the little value, so it cannot be "1-2 kW" constantly consuming by the battery if it was charged up (if you keep constant charging current, say, for the sake of argument, as high as 10Amp, it'll be only about 140W of power, not 1-2 kW!!).Also, judging by the explanation of how to install this thing it connects in parallel to the battery and in my understanding can't do anything useful. To stop charging it has to be in series with the battery. Please correct me if I am wrong.
