Quick Charge SCOXU - Manual (Page 3)

If your charger is programmed for
Lithium Ion batteries the display will
read “FC” Final Charge instead of 80%
To discontinue charging, unplug AC power.
EQUALIZATION:
When using multiple batteries in a series string, cells become
uneven during charge and discharge cycles. At least once a month
perform two charge cycles back to back, this will give a chance for
cells that are lagging behind to catch up, and is important to overall
battery performance. NOTE: This only needs to be done when
using F2, F3, F4, settings, and a gassing/absorption setting of d0
or d2.
