Notes:
1) The host of the terminal voltage 10.8V is the basis for the test, perhaps the
battery voltage is 12V, but lower than the voltage across the host 10.8V, this is
because the power cord to connect the host is too small, resulting in pressure drop
too much. Then please use the thick wire from the battery directly to the host power
supply.
2) The 16V is the voltage for the detection of the host based on the normal 12V
electrical panel in the line, the terminal voltage is 13.8V or so, if more than 16V it is a
problem for the system.
