State Of Charge:
The Kid in conjunction with the Whiz-Bang JR. offer a real battery S tate O f C harge meter.
There is some set-up before using the WBJr. It is necessary to enter values for Battery bank size in Amp-
Hours, battery efficiency, Battery temperature compensation reference, and percentage of change per
degree C. Refer to the battery manufacturer's documentation for these values.
To enable the WBJR on The Kid:
Press Main Menu button.
Scroll to the right, Until Aux is in shown in brackets, <AUX> Press Enter.

Battery Efficiency:
Batteries are not 1 00 percent efficient and some loss does occur. This setting will improve accuracy

will lower with age, 94% is a good starting point for most battery banks. Your battery bank will reach
1 00% charge as soon as it hits float stage.

may vary by manufacturer and battery type.
