Warnings and Safety Notes
battery at a high current rate (amperage) with a charging lead not rated for
the chosen amperage, the wire could get hot, catch fire, short out and/or
potentially destroy your battery and the charger. 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
specific 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 X4 AC Pro discharging functions are for two specific 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
Warning A LITHIUM CELL WILL DO PERMANENT DAMAGE. REFER TO THE
STANDARD BATTERY PARAMETERS TABLE ON PAGE 6 OF THIS MANUAL
FOR MINIMUM DISCHARGE VOLTAGES.
LiPo & LiHV 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 X4 AC
Pro 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 X4 AC Pro
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 first ten cycles will help
ensure full performance and service life from your Lithium cells.
