The charger includes two independent charging channels, each with dedicated battery and balance ports. A speed shuttle key allows for easy navigation through menus and settings. Additionally, a USB 5V port is available for charging external devices, and an update port is provided for firmware upgrades.
Setup
1. Unboxing and Initial Inspection
Carefully remove the HOTA D6 Pro charger and all accessories from its packaging. Inspect the unit for any signs of damage. Ensure all components listed in the packing list are present.

2. Power Connection
Connect the provided AC power cable to the AC input port on the back of the charger and then to a suitable wall outlet (AC 100-240V). Alternatively, for DC input, connect a DC power source (6.5-30V) to the DC input port using an XT60 connector.

3. Initial Power-On
Once powered, the charger will perform a self-check and display the main interface on its IPS screen. The fan may activate upon power-on.
Operating Instructions
1. Navigating the Interface
Use the 'CH' button to switch between Channel 1 and Channel 2. The speed shuttle key (red wheel) is used to scroll through menu options and adjust settings. A short press confirms a selection, and a long press typically exits a menu or stops a task.

2. Connecting Batteries
Connect your battery's main power lead to the XT60 output port for the desired channel (CH1 or CH2). For balanced charging, also connect the battery's balance lead to the corresponding balance port. The charger supports 1S to 6S balance leads directly.

3. Selecting a Task
From the main screen, select the desired channel (CH1 or CH2). Press the speed shuttle key to enter the task settings. You can choose from the following tasks:
- Charge: Standard charging mode. The charger will automatically balance the cells if the balance lead is connected.
- Discharge: Discharges the battery to a specified voltage.
- Ext. Discharge: For completely discharging a battery, often used for disposal.
- Storage: Charges or discharges the battery to a safe voltage level for long-term storage. This is crucial for battery longevity.
- Balance: Rebalances individual cells within a battery pack.
- Sync Charge: Combines the power of both channels to charge a single battery at a higher rate (e.g., for very large capacity batteries).
- Power Supply: Converts the charger into a continuous DC power supply.
4. Setting Battery Parameters
After selecting a task, adjust the battery type, cell voltage (for LiPo/LiHv), cell count (S), and current setting (Amps). Always ensure these settings match your battery's specifications to prevent damage.
Charging Current (1C Rule): For most LiPo batteries, it is recommended to charge at a "1C" rate. This means the charging current in Amps should be equal to the battery's capacity in Amp-hours (Ah). For example, a 750mAh (0.75Ah) battery should be charged at 0.75A. Some batteries may support higher charge rates (e.g., 2C or 3C); always refer to your battery's manufacturer specifications.
5. Wireless Charging
The HOTA D6 Pro features a wireless charging pad on top. Simply place a compatible mobile device (e.g., iPhone X, iPhone 8, Samsung S8) on the pad to initiate wireless charging.

Maintenance
- Keep the charger clean and free from dust and debris.
- Store the charger in a cool, dry place away from direct sunlight and extreme temperatures.
- Regularly check cables and connectors for wear or damage. Replace if necessary.
- Ensure proper ventilation around the charger during operation to prevent overheating.
Troubleshooting
1. "Battery Polarity Connected Wrong" Error
This error indicates that the battery's main power lead is connected with incorrect polarity. Immediately disconnect the battery and re-connect it with the correct positive and negative terminals aligned.
2. "Abnormal Battery Connection" Error
This error can occur if the balance lead is not properly connected or if there is an issue with the battery's internal balance. Ensure the balance lead is fully inserted and check the battery for any physical damage.
3. Charger Not Starting Task
Verify that all battery parameters (type, cell count, voltage, current) are correctly set according to your battery's specifications. Ensure both the main power lead and balance lead (if required for the task) are securely connected. The charger may also prevent starting if a safety parameter (e.g., max capacity, safety timer) is exceeded or if the battery's internal resistance is too high.
4. Fan Always On
The charger's fan may run continuously to maintain optimal operating temperature. This is normal behavior, especially during high-power charging tasks. If the fan noise is a concern, check system settings for volume adjustments, though continuous fan operation is often for cooling efficiency.
