This feature can prevent the user from overcharging their batteries which could lead to damage or injury. If the charger detects a malfunction, the circuit automatically disconnects and an alarm will sound, The operating functions of the X4 AC Plus are controlled through a two-way communication link in order to maintain maximum safety with minimal errors. All of these functions and settings are easily configured by the user. Internal Independent Lithium Battery Balancers Each channel of the X4 employs an individual-cell voltage balancer eliminating the need for an external balancer for balance charging. Balancing Individual Cells during Battery Discharging During the process of discharging, the X4 can monitor and balance each cell of the lithium battery individually. If the voltage of any single cell is abnormal, an error message will display and the discharge process will automatically end. Charges Most Popular Lithium Batteries The X4 is compatible with the three most common Lithium chemistry batteries, Li-Ion, LiPo and LiFe. Multiple Lithium Battery Charge Modes The X4’s programming allows for Fast Charge, Balance Charge or Storage Charge Modes for LiPo, Li-Ion, and LiFe batteries. )DVW&KDUJH0RGH Reduces charging time, but does not balance the cells, this mode only charges the battery to approximately 90% capacity. %DODQFH&KDUJH0RGH Monitors individual cell voltage, keeping the cells within an acceptable voltage range and charges the pack to peak capacity. 6WRUDJH&KDUJH0RGH Used for long-term battery storage. Adjusts the voltage level so the battery will not be damaged during long term storage. Delta Peak Technology for Maximum Safety The automatic charge termination program utilizes Delta-Peak voltage detection. When the battery's voltage exceeds the threshold, the charge process is terminated automatically. Automatic Charging Current Limit The maximum charge rate can be manually set when charging NiCd or NiMH batteries. The X4 will auto-detect when the batteries are fully charged and shut off, even with low impedance NiMH packs. 04 SPECIAL FEATURES Capacity and Processing Time Limit The charging capacity is calculated as the charging current multiplied by time. If the charging capacity exceeds the maximum limit set by the user, the process will terminate automatically. Additionally the user can set the maximum amount of charging time. If the charging time exceeds this limit, the process will terminate automatically. Temperature Threshold* The battery's internal chemical reaction causes the temperature of the battery to rise during the charging process. If the temperature exceeds the limit, the charging process will automatically terminate. * This function is available by connecting an optional temperature probe, which is not included in our package. 5 User Customizable Presets The X4 features 10 individually customizable presets so the user can store the charge and discharge parameters for any particular battery type. These presets can be recalled for the desired battery type without the need for any additional programming. Cyclic Charging / Discharging Batteries can be set to automatically Charge/Discharge or Discharge/Charge up to a maximum of 5 cycles. PC Based Analysis Using USB Communication* The Hitec X4 offers a PC-based program which can analyze the characteristics of the battery via a USB port.

It is critical that the same attention be paid to the discharging process as to the charging process. The final discharge voltage should be set correctly to avoid deep discharging. Lithium batteries cannot be discharged to voltage lower than the minimum voltage for the cell type. Doing so will result in a rapid loss of capacity and/or total failure. Generally, lithium batteries don’t need to be discharged and it is not recommended. If you choose to discharge your lithium batteries make sure to pay attention to the minimum voltage setting. Some rechargeable batteries have a memory effect. If they are partly used and recharged before the complete charge/discharge cycle is accomplished, 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.

CHARGING / DISCHARGING LEAD-ACID (PB) BATTERIES This program is only suitable for charging a lead-acid (PB) type battery with a nominal voltage range of 2 to 20 volts. Lead acid (Pb) batteries can only deliver current lower in comparison to their capacity. The same restriction applies to the charging process. Consequently, the optimum charge current for lead acid (Pb) batteries is only 1/10 of its rated capacity. You cannot fast charge lead acid (Pb) batteries. Please refer to the following specification regarding charging and discharging lead acid (Pb) batteries. Nominal Voltage Level: 2.0V per cell Maximum Charge Voltage: 2.46V per cell Allowable Charge Current: 0.4C or less Discharge Voltage Cut Off Level: 1.75V or higher per cell . 18 CHARGING / DISCHARGING LEAD-ACID (PB) BATTERIES NOTICE Due to the chemistry characteristic of a Pb battery, the cut-off point may be difficult to detect at times.
