This is the Hitec X4-Eighty Four-Channel DC Multi-Charger. Featuring four identical and independent 80-watt power outputs, this easy-to-operate, microprocessor-controlled charger has a total output power of 320 watts! Each port is capable of charging all types of rechargeable batteries at up to 6 amps, whether it is a 6S Lithium pack to 15 NiCd/NiMH cells to 6-12 volt lead acid batteries. Four individual balancing ports eliminate the need for a separate balancer when charging Lithium batteries. Equipped with a twin fan cooling system and an internal sensor for controlling fan speed, the X4-Eighty delivers the reliability and safety required in charging your various types of batteries. Its powerful capability combined with reliable safety functions make it the perfect choice for all electric and nitro modelers. Whether you are a weekend flier, an aerobatic master, a basher or pro racer, this charger is an excellent choice.
Optimized Operating Software
The software in X4-Eighty automatically controls the current rate during the charging or discharging process. 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-Eighty 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-Eighty employs an individual-cell voltage balancer eliminating the need for an external balancer for balance charging.
Charges Most Popular Lithium Batteries
The X4-Eighty is compatible with the three most common Lithium chemistry batteries, Li-Ion, LiPo and LiFe
Multiple Lithium Battery Charge Modes
The X4-Eighty's programming allows for Fast Charge, Balance Charge or Storage Charge Modes for LiPo, Li-Ion, and LiFe batteries.
- Fast Charge Mode: Reduces charging time, but does not balance the cells, this mode only charges the battery to approximately 90% capacity.
- Balance Charge Mode: Monitors individual cell voltage, keeping the cells within an acceptable voltage range and charges the pack to peak capacity.
- Storage Charge Mode: 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-Eighty will auto-detect when the batteries are fully charged and shut off, even with low impedance NiMH packs.
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.
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.
5 User Customizable Presets Per Channel
The X4-Eighty features 5 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-Eighty offers a PC-based program which can analyze the characteristics of the battery via a USB port. It shows a graph of voltage, current and capacity curves. It also displays the individual voltage of each cell in the lithium battery pack.
* A PC-LINK USB adaptor can be purchased separately.
