SPECIAL FEATURES

Optimized operating software

The X1 "auto" feature sets the charge and discharge current for you automatically, preventing overcharging which can damage your battery. In the event of an error, the X1 instantly disconnects the circuit and sounds an alarm once. This feature can be set by the user and controlled through the two-way link for maximum safety and minimizes these type of problems.

Internal independent lithium battery balancer

The X1 features a built-in a cell voltage balancer so you don’t need to fuss with external balancers while charging.

Balancing individual cells during discharging

The X1 also monitors and balances each cell in the pack individually while discharging. If the voltage of any single cell is abnormal, the X1 will display an error message and the process will end automatically.

Adaptable to various types of lithium batteries

The X1 will charge and discharge a variety of Lithium batteries, such as Li-ion, LiPo and the new LiFe series of batteries.

Fast and storage mode of lithium batteries

The X1 features two styles of charging. "Fast" charge reduces the charge duration while "Store" controls the final voltage of your battery, to optimize your packs for long term storage and maximum lifespan.

Maximum safety

Our delta-peak voltage detection program ends the charge cycle whenever a battery's voltage exceeds the set threshold.

- 03 -

SPECIAL FEATURES

Automatic charging current limit

Charging current can set by the user when charging NiCd or

NiMH batteries. The 'AUTO' charging mode, however, is recommended when charging NiMH batteries with low impedance and capacity.

Capacity and Temperature Limits

The charge process will terminate if either the charging capacity or battery temperature exceeds the limit set by the user.

Temperature function requires an optional temperature probe, which is not included with the X1.

Processing time limit

Protect your battery by setting a maximum time limit for charging and discharging.

Input power monitoring

The X1's input voltage is monitored to protect the battery from becoming damaged. The process ends automatically if it drops below the limit.

Data store/load

A maximum of five setting profiles can be stored for your convenience. The X1 will store the data pertaining to a program's settings and you can call up data at anytime.

WARNING AND SAFETY NOTES

To avoid a short circuit between the charge leads, always connect the charge cable to the charger first, then connect the battery. Reverse the sequence when disconnecting.

Do not connect more than one battery pack to this charger at any one time.

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 (may pose an explosion hazard).

Batteries that require a different charge technique from NiCd,

NiMh, LiPo or a 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 those which are electrically linked to other components.

Batteries that are not expressly stated by the manufacturer to be suitable for the currents the charger carries 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).

- 08 -

WARNING AND SAFETY NOTES

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 the charging 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 provided 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.

Connect the battery to the terminal of the charger: red is positive and black is negative. Due to the resistance difference between the cable and the connector, the charger can not detect the resistance of the battery pack. In order for the charger to work properly, the charge leads should be of adequate cross-section with high quality (normally gold-plated) connectors fitted to both ends.

Always refer to the manual provided by the battery manufacturer pertaining to charging methods, recommended charging current and charging time. Lithium batteries, in particular,should be charged strictly according to the charging instructions provided by the manufacturer.

Special attention should be paid to the connection of the Lithium battery.

Do not attempt to disassemble the battery pack arbitrarily.

- 09 -

WARNING AND SAFETY NOTES

Please note that Lithium battery packs can be wired in parallel and in series. In the parallel connection, the battery’s capacity is calculated by multiplying the single battery’s capacity by the number of cells with total voltage remaining the same. The voltage’s imbalance may cause a fire or explosion. A Lithium battery is recommended to charge in series.

Discharging

The main purpose of discharging is to clean the 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. A 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, a Lithium battery doesn’t need to be discharged. Please pay attention to the minimum voltage of a 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. It is said that NiCd and NiMH batteries suffer from this memory effect and 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 used until it has been subjected to 10 or more charge cycles. The cyclic process of charge and discharge will optimize the capacity of the battery pack.

CHK Time 10min

The X1 recognizes the cell count of the Lithium battery automatically at the beginning of the charge or discharge process to avoid an erroneous setting by the user. To prevent a deeply discharged battery, which can be perceived incorrectly, from causing an error, you can set the timer to verify the cell count by the processor. Normally, 10 minutes is enough to perceive the cell count correctly. For a battery of larger capacity, you may extend the time term.

However, if you set the it too long for a battery of smaller capacity, the charge or discharge process can be finished within the time term with an erroneous cell count. This may cause a fatal result.

When the charge process starts, the integrated safety timer starts to run simultaneously. If an error occurs or the termination circuit cannot detect whether the battery is fully charged or not, the unit is programmed to prevent overcharging and will terminate the charge process. Please refer to the statement below to calculate the timer you set.

Safety Timer Calculation

When charging NiCd or NiMH batteries, divide the capacity by the current, then divide the result by 11.9. Set this number of minutes as the setting for the safety timer setting. If the charger stops at this time threshold, about 140% of the capacity will have been fed into the battery.

For example:

Capacity Current Safety Time

2000mAh 2.0A (2000/2.0=1000)/11.9=84 minutes

3300mAh 3.0A (3300/3.0=1100)/11.9=92 minutes
