INTRODUCTION
Congratulations, you have purchased the most advanced and feature
rich Lithium balancer on the market. It is the first ever balancer to
feature three modes of operation; Stand Alone, PC Controlled and
Xtrema balanced charging.

REALITY CHECK: Even though every effort has been made to
provide safe reliable operation with our products, electronic products
can and DO FAIL. DO NOT rely solely on balancing equipment while
charging. Lithium batteries can spontaneously ignite. Supervision
when charging Lithium batteries is mandatory.
PRECAUTIONS - WARNINGS - PLEASE READ ALL OF
THESE!
DO NOT CONNECT the balancer DIRECTLY to the Xtrema
Charger without the Balancer Interface Module - BIM in
between. The BIM has opto-isolators needed for both reverse
polarity protection and because the expansion port ground is at a
different potential than the (-) battery lead. Plugging the balancer
direcly into the Xtrema without the BIM will void your warranty
DO NOT USE the balancer with the Xtrema if the 10 pin ribbon cable
is loose or frayed. Always check all connections!
DO NOT LEAVE the balancer connected to the battery for long
periods after balancing. A tiny amount of power drain is always
present.
DO NOT CHARGE Lithium Polymer / ION batteries unattended.
Ever!
DO NOT CHARGE inside a vehicle
DO NOT CHARGE in direct sunlight
DO NOT CHARGE when ambient temperature is very HIGH or
LOW.
DO NOT CHARGE when Li battery pack is hot or near flames
STAND ALONE OPERATION
For normal Li Polymer, Li Manganese and in general most Li Ion
batteries the Jumper settings may be left at the default settings If you
will be balancing M1 cells (A123 Systems) you must move the jumper
from the default horizontal position to a vertical position across
jumper option 4 before connecting the balancer. (See jumper settings
below.)
Connect the balancer to your lithium pack aligning the negative end
of the balance connector on your battery with the pin on the balancer
labeled BLK (-). After a few seconds you will see the corresponding
number of LED's flash at least once.
If the pack is out of balance the LED's corresponding to cells with the
highest voltage will blink until those cells are reduced to the lowest
cell. The STATUS LED will also blink while balancing indicating how
far out of balance your pack actually is. After a 5 second pause the
LED will blink once for every 10 mv of imbalance up to 200 mv.
Ex: one blink = 10 -19mv. imbalance, two blinks = 20 -29mv, 9 blinks
= 90 - 99mv etc. Over 200 mv imbalance will cause the STATUS LED
to blink continuously.
When the battery is balanced, the display will simply stop blinking. If
at least once cell of the battery is below the minimum acceptable cell
voltage the STATUS LED will come on for 5 seconds and the unit will
then shut down. If all available cell LED's blink together in unison
then they are all over the maximum voltage and the balancer will
bring them down until they are balanced at the max voltage. NOTE:
maximum and minimum voltage are either jumper selectable or finely
adjustable via the PC interface.

PC CONTROLLED OPERATION
You will need our optional Xtrema Data Cable to communicate with
your PC. (part number XTR-USB or XTR-232) This is the same
cable used to connect the Xtrema charger to you PC. Prior to
operation download the free XTRBalancer program and the full
balancer instructions at our web site
