Figure 5 – Whizbang jr. “More” Screen
When the battery is receiving a charge, the accumulated positive Amp-hours
figure will increase, as will the total Net figure. When the battery is being
discharged, the accumulated negative Amp-hours will increase, and the total
(Net) Amp-hours will decrease. As battery charging is not 100% efficient, the
total accumulated Amp-hours or “NET AMP-HOURS” should remain positive after a
discharge-charge cycle. A typical battery efficiency is 94 to 96%.
The Net Amp-hours tally can be configured to reset every time the Classic goes
to float. To set this option, go to the “TWEAKS” menu and press “MORE” four
times. Select “WBRST” and press the UP or DOWN arrow keys to select “YES.”
Press Enter to save. “NO” (or no reset) is the default.
If set to “YES”, only the Net-Amp-Hours will reset. The accumAH and –AH
will keep increasing. These values are stored into non-volatile memory every
night at midnight. If the Classic were to lose power, it would recover
accumulated Amp-hours from the previous day. These values can be cleared from
the Classics Logs menu, please consult the Classics owner’s manual for more
info.
From the WBjr main screen in figure 4 press the upper right button (Right Soft
Key) to take you to the first set up screen.
Figure 6 – Whizbang jr. “Setup” Screen
On this screen we need to set the Capacity of the battery bank. Remember that
batteries in series do not add in Amp Hours, only batteries in parallel.
(Example- 2 strings of 4 6 volt golf cart batteries that are 220 Amp Hours each
wired for 24 volts would be 440Ah) Holding Shift while changing the Ah capacity
will change in steps of 100. The Default setting is 400Ah.
