Ultimate 400W Ultimate 400W
Internal independent lithium battery balancer
Ultimate 400W employs an individual-cell-voltage balancer. It is not necessary to connect an external
balancer for balance charging.
Balancing individual cells battery discharging
During the process of discharging, Ultimate 400W can monitor and balance each cell of the battery
individually. Error message will be indicated and the process will be ended automatically if the voltage of any
single one cell is abnormal.
Adaptable to various type of lithium battery
Ultimate 400W is adaptable to various types of lithium batteries, such as Li-ion, LiPo and the new LiFe series
of batteries.
Fast and storage mode of lithium battery
Purposes to charge Lithium battery varies, fast charge reduce the duration of charging, whereas store state
can control the final voltage of your battery, so as to store for a long time and protect useful time of the battery.
Maximum safety
Delta-peak sensitivity: The automatic charge termination program based on the principle of the Delta-peak
voltage detection. When the battery's voltage exceeds the threshold, the process will be terminated
automatically.
Automatic charging current limit
You can set up the upper limit of the charging current when charging your NiCd or NiMH battery; it is useful for
the NiMH battery of low impedance and capacity in the 'AUTO' charging mode.
SPECIAL FEATURES
WARNING AND SAFETY NOTES
Capacity limit
The charging capacity is always calculated as the charging current multiplied by time. If the charging
capacity exceeds the limit, the process will be terminated automatically when you set the maximum value.
Temperature threshold
The battery internal chemical reaction will cause the temperature of the battery to rise. If the temperature
limit is reached, the process will be terminated.
This function is available by connecting temperature probe, which is not included in the package.
Processing time limit
You can also limit the maximum process time to avoid any possible defect.
Data store/load
For user’s convenience, it can store maximum 10 data of different batteries. You can establish
the data contains program setting of the battery to charge or discharge. These data can be called
back at any time you need and the process can be executed without program setting.
Cyclic charging/discharging
1 to 5 cyclic and continuous process of charge>discharge or discharge>charge is operable for battery
refreshing and balancing to stimulate the batterys activity.

These warnings and safety notes are particularly important. Please follow the instructions for maximum
safety; otherwise the charger and the battery can be damaged or at worst it can cause a fire.
Never leave the charger unattended when it is connected to its power supply. If any malfunction is
found, Terminate THE PROCESS AT ONCE and refer to the operation manual.
Keep the charger well away from dust, damp, rain, heat, direct sunshine and vibration. Never drop it.
The allowable input voltage is 12~18V DC
This charger and the battery should be put on a heat-resistant, noninflammable and nonconductive
surface. Never place them on a car seat, carpet or similar.
Keep all the inflammable volatile materials away from operating area.
Make sure you know the specifications of the battery to be charged or discharged to ensure it meets
the requirements of this charger. If the program is set up incorrectly, the battery and charger may be
damaged .It can cause fire or explosion due to overcharging. This warranty is not valid for any damage
or subsequent damage arising as a result of a misuse or failure to observe the procedures outlined in
this manual.
Charge in an environment where the temperature range is between 10℃-30℃（50℉-86℉）.
Charging may not be as effective when performed in other environments.

Never attempt to charge or discharge the following types of batteries.
A battery pack which consists of different types of cells (including different manufacturers)
A battery that is already fully charged or just slightly discharged.
Non-rechargeable batteries (Explosion hazard).
Batteries that are require a different charge technique from NiCd, NiMh, LiPo or Gel cell
(Pb, Lead acid).
A faulty or damaged battery.
A battery fitted with an integral charge circuit or a protection circuit.
Batteries installed in a device or which are electrically linked to other components.
Batteries that are not expressly stated by the manufacturer to be suitable for the currents
the charger delivers during the charge process.
Please bear in mind the following points before commencing charging:
Did you select the appropriate program suitable for the type of battery you are charging?
Did you set up 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 firm and secure?
Make sure there are no intermittent contacts at any point in the circuit.
Charging
During charge process, a specific quantity of electrical energy is fed into the battery. The charge quantity is
calculated by multiplying charge current by charge time. The maximum permissible charge current varies
depending on the battery type or its performance, and can be found in the information by the battery
manufacturer. Only batteries that are expressly stated to be capable of quick-charge are allowed to be
charged at rates higher than the standard charge current.
WARNING AND SAFETY NOTES
WARNING AND SAFETY NOTES
Connect the battery to the terminal of the charger: red is positive and black is negative. Due to the
difference between resistance of cable and connector, the charger can not detect resistance of the battery
pack, the essential requirement for the charger to work properly is that the charge lead should be of
adequate conductor cross-section, and high quality connectors which are normally gold-plated should be
fitted to both ends.
Always refer to the manual by the battery manufacturer pertaining to charging methods, recommended
charging current and charging time. Especially, the Lithium battery should be charged according the
charging instruction provided by the manufacturer strictly.
Attention should be paid to the connection of Lithium battery especially.
Do not attempt to disassemble the battery pack arbitrarily.
Please get highlighted that Lithium battery packs can be wired in parallel and in series. In the parallel
connection, the battery capacity is calculated by multiplying single battery capacity by the number of cells
with total voltage stay the same. The voltage imbalance may cause fire or explosion. Lithium battery is
recommended to charge in series.

Discharging
The main purpose of discharging is to clean residual capacity of the battery, or to reduce the
battery voltage to a defined level. The same attention should be paid to the discharging process as
charging. The final discharge voltage should be set up correctly to avoid deep-discharging. Lithium
battery can not be discharged to lower than the minimum voltage, or it will cause a rapid loss of
capacity or a total failure. Generally, Lithium battery doesn’t need to be discharged. Please pay
attention to the minimum voltage of Lithium battery to protect the battery.
Some rechargeable batteries have a memory effect. If they are partly used and recharged before
the whole charge is accomplished, they remember this and will only use that part of their capacity
next time. This is a memory effect. It is said that NiCd and NiMH batteries are suffering from memory
effect. NiCd has more memory effect than NiMH.
Lithium batteries are recommended to be discharged partially rather than fully discharged. Frequent
full discharging should be avoided if possible. Instead, charge the battery more often or use a
battery of larger capacity. Full capacity cannot be reached until it has been subjected to 10 or more
charge cycles. The cyclic process of charge and discharge will optimize the capacity of battery pack.
