• Did you set up the adequate current for charging or discharging?
• Have you checked the battery voltage? Lithium battery packs can be wired in parallel and
in series, i.e. a 2-cell pack can be 3.7V (in parallel) or 7.4V (in series).
• Have you checked that all connections are fi rm and secure?
• Make sure there are no intermittent contacts at any point in the circuit.
WHEN ADJUSTING YOUR X1-200 TOUCH CHARGING PARAMETERS, BE SURE
YOU SELECT THE PROPER BATTERY TYPE AND CELL VOLTAGE FOR THE TYPE
OF CELL YOU ARE CHARGING. CHARGING BATTERIES WITH THE WRONG SET-
TINGS MAY CAUSE THE CELLS TO BURST, CATCH FIRE OR EXPLODE.
Charging
Before charging your batteries, it is critical that you determine the maximum allowable
charge rate for your batteries. The X1-200 Touch is capable of charging at high rates that may
not be suitable or safe for your particular batteries. For example, Lithium cells are typically
safe to charge at 1C, or the total mAh÷1000. A 1200mAh battery would have a 1C charge rate
of 1.2 amps. A 4200mAh battery would have a 1C charge rate of 4.2 amps. Some manufactur-
ers are off ering Lithium cells that can be charged at greater than 1C but this should ALWAYS
be verifi ed before charging a Lithium battery at rates higher than 1C. Voltage is just as critical
as the charging amperage rate and this is determined by the number of cells in series, or “S”.
For example, a 3S LiPo is rated at 11.1 volts (“S” multiplied by a single LiPo cell with a nominal
voltage of 3.7 volts DC. 3 cells x 3.7 volts each equals 11.1 volts DC).
Connect the battery’s main leads to the charger output: red is positive and black is negative.
Keep in mind that the gauge or thickness of your charging leads from the X1-200 Touch to
your battery must be of an acceptable current rating to handle the applied charge current.
For maximum safety and charging eff ectiveness, always match or exceed the main battery
lead rating when assembling or selecting your charging leads. If you charge a battery at a
high current rate (amperage) with a charging lead not rated for the chosen amperage, the
wire could get hot, catch fi re, short out and/or potentially destroy your battery and the char-
ger. When in doubt, always use a higher gauge wire (lower AWG number). It is common to see
charging leads constructed of 14AWG, 16AWG or 18AWG wire.
Always refer to recommendations from your battery manufacturer for your specifi c battery
type and size before initiating a charge or discharge process.
Do not attempt to disassemble or modify Lithium or Lead-Acid battery packs.
Discharging
The X1-200 Touch discharging functions are for two specifi c purposes:
• Refreshing the capacity of a Nickel-based battery that has lost capacity over time (NiMH or
NiCd).
• Reducing the voltage of a Lithium battery for safe storage.
LITHIUM CHEMISTRY BATTERY PACKS SHOULD ONLY BE DISCHARGED TO
THEIR MINIMUM SAFE VOLTAGE, NO LOWER. DEEP DISCHARGING A LITHIUM
CELL WILL DO PERMANENT DAMAGE. REFER TO THE STANDARD BATTERY
PARAMETERS TABLE ON PAGE 10 OF THIS MANUAL FOR MINIMUM DIS-
CHARGE VOLTAGES.
LiPo charge/discharge cycling – Lithium batteries are known to reach full capacity after a
break-in period of about 10 charge/discharge cycles. We do not recommend you use the
X1-200 Touch charger to do this, normal use and recharging will achieve the same results.
If you wish to perform a Lithium break-in on the bench with the X1-200 Touch, discharging
to minimum acceptable voltages and performing a balance charge at 1C maximum rate is
recommended. If you choose to break in your Lithium batteries under normal use, charging
at only 1C for the fi rst ten cycles will help ensure full performance and service life from your
Lithium cells.

POWER SUPPLY CONNECTIONS
The X1-200 Touch requires a DC power supply for operation. You can use a 12VDC
automotive battery or an 11 ~ 18 Volt DC Power Supply with an output current of
at least 12 Amps. If using an automotive type battery, make sure it is fully charged
before using the X1-200. A fully charged 12VDC automotive battery should have a
nominal voltage of about 13.8V.
Using alligator terminal clips
attached to a car battery.
Using the supplied 4mm bullet
connectors and ePower 30A power
supply.
