Discharging
The main purpose of discharging a battery is to clean the residual capacity of the
battery or to reduce the battery’s voltage to a defined level. It is even more critical that
close attention be paid to the discharging process as failure to properly monitor the
process can destroy your batter. The final discharge voltage should be set correctly to
avoid deep discharging. Some rechargeable batteries have a memory effect. If they
are partly used and recharged before the complete charge/discharge cycle is accom-
plished, they remember this and will only use that part of their capacity next time. It is
generally known that NiCd and NiMH batteries suffer from this memory effect.
Discharging Lithium Batteries
Lithium batteries cannot be discharged to a voltage lower than the minimum voltage
for the cell type. Doing so will result in a rapid loss of capacity and/or total failure.
While the X2-400 monitors each individual cell during the discharge process the
discharging cutoff is based on the total pack voltage. Generally, lithium batteries don’t
need to be discharged and it is not recommended that you discharge them. If you do
choose to discharge your lithium batteries make sure to pay attention to the minimum
voltage setting as well as the individual cell voltage.

POWERING THE CHARGER
WARNINGS AND SAFETY INFORMATION
The Hitec X2-400 charger can also be powered by a 12VDC car battery using the
included large terminal clips with matching 4mm female bullet connectors or it can be
connected directly to a DC power supply. When connecting to a battery or power supply
it is critically important that you use either a fully charged 12 volt car battery or a high
quality DC power supply that has a voltage range between 12 to 18 volts DC and a
minimum current rating of 60 amps. Failure to use proper input power can result in unreli-
able performance and may damage the charger.
