5.5 Equalization
CAUTION
Proper equalization is necessary for the health of the pack. Too little equalizing may lead to
sulfation and decreased capacity, whereas excessive equalizing may lead to high water loss and
more maintenance. We recommend equalizing at least once a week, possible more with heavy
usage.
The equalization schedule is stored in the BMID and run automatically (see the "BMID
Programming Manual" for information on how to modify the pre-set equalization schedule). To
manually schedule an equalization during a charge, press the "Equalize" button at any time during
a charge, the equalize light will start flashing indicating an equalization is scheduled, and the
battery pack will be equalized following the fast charge.
To bypass the fast charge and start an equalization charge on a battery pack at any state of
charge, press and hold the "Equalize" button for three (3) seconds, the equalize light will illuminate
without flashing, and the charger will start a partial equalization on the pack without a fast charge.
Note: The charger EQ button may be configured to only work under certain conditions (EQ day of
week, etc.). Please review the advanced features manual for details.

IMPORTANT INFORMATION – SAVE THESE INSTRUCTIONS
Always run a full equalization charge prior to a fast charge on any battery
pack that has had a cell replaced to ensure the pack is balanced.
