More Info on the Hobbymate AC/DC Balance Multicharger Quad Port

Equipped it with a built-in AC Switchable 110-240v power supply, Hobbymate Quad charger has four-port computer controlled capability with a built-in 550W power supply which can be powered by standard 110-220 volt AC household current. Simple to use and utterly reliable, this compact charger with battery management and integral balancer features four identical and independent 50-watt power outputs, for a total output power of 480 watts. Each port of the Hobbymate Quad can handle up to a 6S Lithium pack, 15 NiCd/NiMH cells or 6-12 volt lead acid batteries. Four individual balancing ports eliminate the need for a separate balancer when charging Lithium batteries. Its twin fan cooling system with an internal sensor for controlling fan speed provides the utmost in efficiency and safety.

The Hobbymate Quad charger can accept a variety of power inputs including the option of attaching it to a 12-volt car battery or a 11¨C18 volt DC power supply (450W max).

The Hobymate Quad charger offers a complete charging solution for novice and expert RC enthusiasts alike. The multi-tasking versatility of this new charger makes it a perfect fit for nitro and electric modelers, regardless of what you drive, hover, float or fly.

Optimized Operating Software

The software in Hobbymate Quad charger 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 Hobbymate Quad charger 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 Hobbymate Quad charger 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 Hobbymate Quad charger 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 Hobbymate Quad charger is compatible with the four most common Lithium chemistry batteries, Li-Ion, LiPo, LiHv and LiFe

Multiple Lithium Battery Charge Modes

The Hobbymate Quad charger's programming allows for Fast Charge, Balance Charge or Storage Charge Modes for LiPo, Li-Ion, LiHv 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 AC Plus 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.

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 Per Channel

The Hobbymate Quad charger 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 Hobbymate Quad charger 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.

Lithium Battery Meter

Check the voltage of a Lithium battery¡¯s cells when plugged into the balance port. The screen will provide a readout of each cell?s voltage, the total pack voltage, as well as the highest and lowest cells.

Battery Memory

You can program and store up to 10 different types of battery settings on each port. Then simply load the program to start charging using your stored battery settings.

Battery internal resistance meter

The user can detect the resistance of a single cell and the total internal resistance of the battery. Please connect the battery to the charger with main battery lead and balance wires to balance socket.
